Abstract

Although remdesivir, a prodrug of nucleoside analog (GS‐441524), has demonstrated clinical benefits in coronavirus disease 2019 (COVID‐19) treatment, its pharmacokinetics (PKs) in patients with COVID‐19 remain poorly understood. Therefore, in this study, the PKs of remdesivir and its major metabolite, GS‐441524, were evaluated using a population PK (PopPK) approach to understand the PK aspect and exposure–clinical outcome relationship. The serum concentrations of remdesivir and GS‐441524 (102 points in 39 patients) were measured using liquid chromatography–tandem mass spectrometry. All patients received 200 mg remdesivir on the first day, followed by 100 mg on 2–5 days, except for one patient who discontinued remdesivir on day 4. The median (range) age, body surface area, and estimated glomerular filtration rate (eGFR) were 70 (42–85), 1.74 m² (1.36–2.03), and 68 mL/min/1.73 m² (33–113), respectively. A compartment model with first‐order elimination combined with remdesivir and GS‐441524 was used for nonlinear mixed‐effects model analysis. Remdesivir was rapidly eliminated after infusion, whereas GS‐441524 was eliminated relatively slowly (half‐time = 17.1 h). The estimated apparent clearance (CL) and distribution volume of GS‐441524 were 11.0 L/h (intersubject variability [ISV]% = 43.0%) and 271 L (ISV% = 58.1%), respectively. The CL of GS‐441524 was significantly related to the eGFR (CL × [eGFR/68]^0.745). The post hoc area under the curve of GS‐441524 was unrelated to the recovery rate or aspartate aminotransferase/alanine aminotransferase elevation. Overall, PopPK analysis showed the rapid elimination of remdesivir in the blood, and GS‐441524 accumulation depended on eGFR in patients with COVID‐19. However, no relevance of exposure–clinical outcome was not suggestive of the dose adjustment of remdesivir.

PURPOSE: This study evaluated the risk of medication-related osteonecrosis of the jaw (MRONJ) in patients with cancer who received denosumab or zoledronic acid (ZA) for treating bone metastasis. METHODS: The medical records of patients were retrospectively reviewed. Patients who did not undergo a dental examination at baseline were excluded. The primary endpoint was a comparison of the risk of developing MRONJ between the denosumab and ZA groups. Propensity score matching was used to control for baseline differences between patient characteristics and compare outcomes for both groups. RESULTS: Among the 799 patients enrolled, 58 (7.3%) developed MRONJ. The incidence of MRONJ was significantly higher in the denosumab group than in the ZA group (9.6% [39/406] vs. 4.8% [19/393], p = 0.009). Multivariate Cox proportional hazards regression analysis revealed that denosumab treatment (hazard ratio [HR], 2.89; 95% confidence interval [CI], 1.65-5.25; p < 0.001) and tooth extraction after starting ZA or denosumab (HR, 4.26; 95% CI, 2.38-7.44; p < 0.001) were significant risk factors for MRONJ. Propensity score-matched analysis confirmed that the risk of developing MRONJ was significantly higher in the denosumab group than in the ZA group (HR, 2.34; 95% CI, 1.17-5.01; p = 0.016). CONCLUSION: The results of this study suggest that denosumab poses a significant risk for developing MRONJ in patients treated for bone metastasis, and thus these patients require close monitoring.

Background: Enzalutamide is useful for the treatment of castration-resistant prostate cancer (CRPC). Despite its usefulness, adverse events (AEs) sometimes force patients to discontinue treatment. To maximize patient care, we developed an ambulatory care pharmacy practice that allows collaboration between a pharmacist and urologist to manage patients with CRPC receiving enzalutamide. In this study, we investigated the efficacy of this collaborative management. Methods: A retrospective chart review of 103 patients with CRPC receiving enzalutamide in our hospital between May 2014 and December 2020 was performed. Our collaborative management was implemented in October 2016. Before being examined by urologists, patients visited the oncology pharmacy consultation room for a face-to-face consultation, wherein the oncology pharmacists assessed factors such as adherence to enzalutamide, any AEs and their grades, and provided their suggestions to the urologists. The time to enzalutamide discontinuation and prostate-specific antigen progression were compared between patients who started enzalutamide before (n = 41) and after (n = 62) the implementation of the collaborative management. A multivariate Cox regression analysis was performed to analyze the factors associated with enzalutamide discontinuation. Results: After implementing collaborative management, the pharmacists had 881 patient consultations. Among the 476 suggestions from pharmacists, 345 were accepted by urologists. The most frequent suggestion was supportive care in enzalutamide treatment (224 suggestions). Multivariate analysis showed that collaborative management [hazard ratio (HR) 0.53, 95% confidence interval (CI) 0.31-0.89, p = 0.017] and higher prostate-specific antigen (PSA; HR 2.41, 95% CI 1.36-4.28, p = 0.003) were significantly associated with enzalutamide discontinuation. The median time to discontinuation (18.9 vs. 7.6 months, p = 0.012), time to discontinuation due to AEs (not reached in both groups, p = 0.001), and time to PSA progression (13.3 vs. 5.8 months, p = 0.002) were all significantly longer in the after group. Conclusions: We implemented a pharmacist-urologist collaborative management program for outpatients with CRPC receiving enzalutamide. The results revealed that collaborative management was useful for prolonging the time to enzalutamide discontinuation.

The antiretroviral drug favipiravir inhibits RNA-dependent RNA polymerase. It has been developed for the treatment of novel coronavirus (SARS-CoV-2) infection disease (COVID-19). However, its pharmacokinetics in patients with COVID-19 is poorly understood. In this study, we measured favipiravir serum concentration by liquid chromatography-tandem mass spectrometry and conducted population pharmacokinetic (PPK) analysis. Thirty-nine patients were enrolled in the study: 33 were administered FPV 1600 mg twice-daily (BID) on the first day followed by 600 mg BID, and 6 were administered FPV 1800 mg BID on the first day followed by 800 mg or 600 mg BID. The median age was 68 years (range, 27-89 years), males were 31 (79.5%), median body surface area (BSA) was 1.72 m² (range, 1.11-2.2), and patients requiring invasive mechanical ventilation (IMV) at the start of favipiravir was 10 (25.6%). Two-hundred and four serum concentrations were available for pharmacokinetic analysis. A one-compartment model with first-order elimination was used to describe the pharmacokinetics. The estimated mean clearance/bioavailability (CL/F) and distribution volume/bioavailability (V/F) were 5.11 L/h and 41.6 L, respectively. Covariate analysis revealed that CL/F was significantly related to dosage, IMV use, and BSA. Simulation study showed that the 1600 mg/600 mg BID regimen was insufficient for the treatment of COVID-19 targeting EC50 (9.7µg/mL), especially in patients with larger BSA and/or IMV. A higher favipiravir dosage is required for COVID-19, but dose-dependent nonlinear pharmacokinetics may cause an unexpected significant pharmacokinetic change and drug toxicity. Further studies are warranted to explore the optimal favipiravir regimen.

<h4>Background</h4>Pneumocystis pneumonia (PCP) is a potentially life-threatening infection. Trimethoprim-sulfamethoxazole (TMP-SMX) is considered as the first regimen for PCP prophylaxis according to several guidelines. The recommended prophylactic dose of TMP-SMX has been determined based on patients with normal renal function, but the appropriate dosage for patients undergoing hemodialysis is unknown. The aim of this study was to investigate the efficacy and safety of low-dose TMP-SMX in patients undergoing hemodialysis.<h4>Methods</h4>HIV-uninfected adult patients who were undergoing hemodialysis and administered TMP-SMX for PCP prophylaxis, were included, and divided into standard-dose (≥6 single strength (SS, TMP-SMX 80 mg/400 mg tablets/week) and low-dose groups (< 6 SS tablets/week). The endpoints were cumulative incidence of PCP and cumulative discontinuation rate of TMP-SMX due to adverse events. For comparison of the groups, we employed the chi-squared test for categorical variables and the Mann-Whitney U test for continuous variables. Risk factors for the endpoints were evaluated using the Cox Fine and Gray method.<h4>Results</h4>The median age of the 81 patients included in the study was 67 years (IQR: 60-76 years), and 52 patients (64.2%) were men. No patients in either group developed PCP during the observation period. The yearly cumulative incidence of discontinuation was 12.1% (95% confidence interval [CI]: 0.027-0.29) in the low-dose group and 35.6% (95% CI: 0.20-0.52) in the standard-dose group (P = 0.019). The adjusted hazard ratio of the low-dose group compared to standard-dose group was 0.18 (95% CI: 0.04-0.86, P = 0.032).<h4>Conclusions</h4>None of the study patients developed PCP, and the cumulative discontinuation rate of TMP-SMX due to adverse events was significantly lower in the low-dose group compared to that in the standard-dose group (P = 0.032). These results indicate that low-dose TMP-SMX is an appropriate regimen to maintain a balance between PCP prophylaxis and prevention of adverse events due to TMP-SMX administration. These findings can guide health care professionals to determine TMP-SMX dosage when considering PCP prophylaxis for patients undergoing hemodialysis.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common adverse event associated with several antineoplastic drugs; however, the precise risks and time course of reactions of particular drugs are not clearly understood. The aim of this study was to evaluate the relationship between anticancer agents and CIPN development using data from the Japanese Adverse Drug Event Report (JADER) database and to characterize the time-to-onset and outcomes of CIPN. Chemotherapy-induced peripheral neuropathy was defined using the Medical Dictionary for Regulatory Activities preferred terms. Disproportionality analysis was performed by calculating the reporting odds ratio (ROR) with 95% confidence interval for signal detection. Data of nine Anatomical Therapeutic Chemical (ATC) drug categories correlated with CIPN development, in addition to the data of the time-to-onset and outcomes. Among 622,289 reports in the JADER database from April 2004 to March 2020, there were 1883 reports of adverse events corresponding to peripheral neuropathy. The ROR (95% confidence interval) for vinblastine, sorbent-based paclitaxel (sb-PTX), oxaliplatin, and bortezomib was 20.4 (12.5-33.4), 13.6 (11.9-15.7), 26.2 (23.6-29.1), and 30.8 (26.6-35.8), respectively. The median duration (interquartile range) to CIPN development after the administration of vinca alkaloids and analogues, taxanes, platinum compounds, and monoclonal antibodies was 11.0 (5.0-46.5), 22.5 (6.0-82.5), 22.0 (6.0-68.5), and 32.5 (11.3-73.8) days, respectively. The median duration (interquartile range) of sb-PTX and nanoparticle albumin-bound (nab)-PTX was 35.0 (7.0-94.0) and 5.5 (3.0-29.3) days, respectively. Our analysis of records in the JADER database revealed several drugs associated with a high risk for CIPN development. In particular, the development of CIPN after vinca alkaloid administration should be closely monitored for 2 weeks after administration. CIPN caused by nab-PTX showed significantly faster onset than that by sb-PTX. Patients who receive taxanes or monoclonal antibodies often do not show an improvement; accordingly, early treatment is required.

Drug-induced gastrointestinal obstruction (DIGO) and gastrointestinal perforation (DIGP) may be the result of gastrointestinal hypomotility and severe constipation, which may lead to potentially fatal complications of bowel ischemia, sepsis and perforation. We evaluated the onset profile of DIGs (DIGO and DIGP) associated with prescription drugs by analyzing data in the Japanese Adverse Drug Event Report (JADER) database. We selected 161 DIG-related drugs and categorized them into 19 classes based on the Anatomical Therapeutic Chemical (ATC) Classification System. Finally, we focused on 58 drugs and conducted subsequent analyses for the time-to-onset and outcomes. We extracted 79 preferred terms (PTs) with the strings "ileus," "stenosis," "obstruction," "obstructive," "impaction," "perforation," "perforated," "hypomotility," and "intussusception" from the Standardized Medical Dictionary for Regulatory Activities (MedDRA) Queries (SMQs) of SMQ20000104: gastrointestinal perforation, ulcer, hemorrhage, obstruction non-specific findings/procedures; SMQ20000105: gastrointestinal obstruction; and SMQ20000107: gastrointestinal perforation. Among the 667, 729 reports in the JADER database submitted between April 2004 and November 2020, we identified 11,351 occurrences of DIGs. The reporting odds ratios (RORs) (95% confidence interval) of "barium sulfate containing X-ray media," "drugs for treatment of hyperkalemia and hyperphosphatemia," and "oral bowel cleanser" were 142.0 (127.1-158.6), 25.8 (23.1-28.8), and 29.7 (24.8-35.6), respectively. The median number of days (interquartile range) until the onset of an adverse event caused by each drug category was as follows: barium sulfate containing X-ray contrast media [2.0 (1.0-3.0)], diazepines, oxazepines, thiazepines, and oxepines [8.0 (8.0-18.5)], drugs for treatment of hyperkalemia and hyperphosphatemia [29.0 (8.0-55.0)], non-selective monoamine reuptake inhibitors [19.0 (7.0-47.5)], and oral bowel cleanser [0.0 (0.0-0.0)]. Depending on the drug, the time to onset of side effects ranged from days to several months. Our results highlighted the need to perform detailed monitoring of each drug for possible association with DIGs, which might otherwise have fatal consequences.

<jats:p><jats:bold>Background:</jats:bold> Pirfenidone is an anti-fibrotic agent used to treat patients with idiopathic pulmonary fibrosis (IPF). Managing adverse drug events and ensuring compliance with pirfenidone treatment for a prolonged period are important to reduce the rate of disease progression. To maximize the benefits of pirfenidone treatment, we established and evaluated an ambulatory care pharmacy practice, a model of pharmacist–physician collaborative management, for patients receiving pirfenidone.</jats:p><jats:p><jats:bold>Methods:</jats:bold> We conducted a retrospective chart review of 76 consecutive patients treated with pirfenidone in the Kobe City Medical Center General Hospital, Japan, between January 2012 and January 2019. The first group (61 patients) received pirfenidone treatment as conventional management, whereas the second group (15 patients) started pirfenidone based on collaborative pharmacist–physician management. The drug discontinuation rate and time to drug discontinuation were compared between the groups. To analyze factors associated with pirfenidone discontinuation, we used a multivariate Cox regression analysis to evaluate the baseline characteristics of patients, including those receiving the collaborative management. Clinical outcomes were compared using a propensity score matched analysis.</jats:p><jats:p><jats:bold>Results:</jats:bold> In the collaborative management group, pharmacists made 56 suggestions, including suggestions for supportive care (51 suggestions), to the physicians.

PURPOSE:The aim of our study was to characterize the clinical features of immune-related adverse events (irAEs) associated with immune checkpoint inhibitors (ICIs) in a real-world setting using the Japanese Adverse Drug Event Report (JADER) database. METHODS:The irAEs were defined using the preferred terms of the Medical Dictionary for Regulatory Activities. irAEs were categorized as follows: adrenal insufficiency, colitis, eye diseases, hematological disorder, hepatitis, hyperthyroidism, hypopituitarism, hypothyroidism, myasthenia gravis, myocarditis, nephritis/renal dysfunction, pneumonitis, rash, and type 1 diabetes mellitus. We used several indices such as reporting odds ratio (ROR) to assess disproportionality in pharmacovigilance data, time-to-onset analysis using Weibull shape parameters, and the association rule mining technique to evaluate possible risk factors between variables in the spontaneous reporting system database. RESULTS:The JADER database contained 534 688 reports from April 2004 to June 2018. The RORs of pneumonitis including interstitial lung disease for nivolumab, pembrolizumab, and ipilimumab were 7.02 (95% confidence interval: 6.55-7.52), 9.08 (8.28-9.97), and 1.74 (1.27-2.38), respectively. The median onsets (quartiles, 25-75%) of myocarditis caused by nivolumab and pembrolizumab were 28.0 (15.5-60.5) and 18.0 (13.0-44.5) days, respectively. Co-therapy with nivolumab and ipilimumab may be associated with irAEs in several categories as per the association rule mining analysis. CONCLUSION:Our results demonstrated a potential risk of irAEs associated with ICIs, based on RORs and time-to-onset analysis. Furthermore, our findings indicated that patients receiving nivolumab and ipilimumab as co-therapy should be carefully monitored.

The aim of this retrospective study was to identify variable factors affecting tacrolimus blood concentration during the switch from continuous intravenous infusion to twice-daily oral administration in allogeneic hematopoietic stem cell transplant recipients (n = 73). The blood concentration/dose ratio of tacrolimus immediately before the change from continuous infusion (C/Div) was compared with that between 3 and 5 days after the change to oral administration (C/Dpo). Median (C/Dpo)/(C/Div) was 0.21 (range 0.04-0.58). Multiple regression analysis showed that concomitant use of oral itraconazole or voriconazole significantly increased the (C/Dpo)/(C/Div) of tacrolimus (p = 0.002), probably owing to the inhibition of enterohepatic cytochrome P450 3A4. In addition, 5 of 18 (28%) patients who had the lowest quartile (C/Dpo)/(C/Div) values developed acute graft-versus-host-disease (GVHD), which was significantly higher than in others [5 of 55 (9%) patients, p = 0.045]. Although the switch from intravenous to oral administration at a ratio of 1:5 appeared to be appropriate, a lower conversion ratio was suitable in patients taking oral itraconazole or voriconazole. In patients whose blood concentration decreases after the switch, the development of GVHD should be monitored and tacrolimus dosage should be readjusted to maintain an appropriate blood concentration.

Pemetrexed plus carboplatin therapy is widely administered to patients with non-squamous non-small cell lung cancer. Although severe neutropenia is often observed during this combination therapy, its predictive factors are unknown. Therefore, we investigated the predictive factors for severe neutropenia in 77 patients treated with this combination therapy at the Department of Respiratory Medicine, Kyushu University Hospital, between September 2009 and September 2013. All data were retrospectively collected from the electronic medical record system, and univariate and multivariate logistic regression analyses were performed to identify risk factors for grade 3 or 4 neutropenia. Among the 77 patients, 34 (44%) developed grade 3 or 4 neutropenia. Multivariate analysis revealed that lower baseline hemoglobin values (odds ratio [OR], 1.97 per 1 g/dL decrease; 95% confidence interval [CI], 1.39-2.99, p<0.01) and lower baseline neutrophil counts (OR, 1.71 per 1000/mm(3) decrease; 95% CI, 1.14-2.71, p=0.01) were significantly associated with grade 3 or 4 neutropenia. During 4 courses of pemetrexed plus carboplatin therapy, the incidence of grade 3 or 4 neutropenia in patients with baseline hemoglobin values of <11.6 g/dL was significantly higher than that in patients with values of ≥11.6 g/dL [84% (16/19) vs. 31% (18/58), p<0.001]. In conclusion, patients with lower baseline neutrophil counts or lower baseline hemoglobin values, especially those with baseline hemoglobin values of <11.6 g/dL, should be monitored more carefully during pemetrexed plus carboplatin therapy.

BACKGROUND: Differences in error rates between pharmacists and nurses in terms of drug confirmation have not been studied. The purpose of this study was to analyze differences in error rates between pharmacists and nurses from the viewpoint of error categories, and to clarify differences in recognition regarding drug name similarity. METHODS: In this study, preparation errors and incidents were classified into three categories (drug strength errors, drug name errors, and drug count errors) to investigate the influence of error categories on pharmacists and nurses. In addition, errors in two categories (drug strength errors and drug name errors) were reclassified into another two error groups, to investigate the influence of drug name similarity on pharmacists and nurses: a "drug name similarity (-) group" and a "drug name similarity (+) group". Then, differences in error rates of pharmacists and those of nurses were analyzed respectively within three categories and two groups. Furthermore, differences in error rates between pharmacists and nurses were analyzed in each of the three categories and two groups. RESULTS: Error rates of pharmacists for both drug strength errors and drug name errors were significantly higher than that for drug count errors, and similar results were obtained for nurses (P < 0.05). However, there were no significant differences in error rates between pharmacists and nurses in each of the three categories. Furthermore, error rate of nurses was significantly higher than that of pharmacists in the drug name similarity (+) group (P < 0.05), while there was no significant difference in error rates between pharmacists and nurses in the drug name similarity (-) group. CONCLUSIONS: These results suggest that in contrast to pharmacists, nurses are easily affected by similarities in drug names. Therefore, pharmacists should offer information on medications having plural strengths or similar names to nurses, in order to minimize damage to patients resulting from errors.

BACKGROUND: Severe hypocalcemia sometimes develops during denosumab treatment for bone metastases from cancer and is, therefore, an important issue. However, limited information is available on the risk factors for hypocalcemia and the appropriate interval for monitoring serum calcium concentration. OBJECTIVE: The present study aimed to identify the risk factors for grade ≥2 hypocalcemia and to investigate the time course of serum calcium concentrations in patients receiving denosumab for bone metastases from cancer. METHOD: The medical records of 66 cancer patients treated with denosumab between April 2012 and August 2013 were retrospectively reviewed. RESULT: Of the 66 enrolled patients, 11, 5, and 1 developed grade 1, 2, and 3 hypocalcemia, respectively. All 4 patients with a baseline estimated glomerular filtration rate (eGFR) of <30 mL/min developed hypocalcemia. Hypocalcemia occurred in only 20%, 24%, and 15% of patients with an eGFR of 30 to 59, 60 to 89, and ≥90 mL/min, respectively. Multivariate logistic regression analysis revealed that lower eGFR values (odds ratio, 1.72 per 10 mL/min decrease, P = 0.02) were significantly associated with grade ≥2 hypocalcemia. In 11 patients who developed hypocalcemia during the first treatment course, the mean calcium concentrations decreased from 9.8 mg/dL at baseline to 8.4 mg/dL during the first week and reached a nadir of 8.1 mg/dL during the second week. CONCLUSION: Our results support more frequent monitoring of serum calcium concentrations at baseline and during the first 2 weeks of treatment in patients receiving denosumab, especially those with an eGFR <30 mL/min.

STUDY OBJECTIVE: To evaluate the efficacy and safety of aprepitant added to standard antiemetic regimens used in high-dose chemotherapy for allogeneic hematopoietic stem cell transplantation (allo-HSCT). DESIGN: Retrospective medical record review. SETTING: Hematology ward of a university hospital in Japan. PATIENTS: Of 88 patients treated with high-dose chemotherapy followed by allo-HSCT, 46 received aprepitant and granisetron as antiemetic therapy (between April 1, 2010, and December 31, 2011), and 42 received granisetron alone (between April 1, 2008, and March 31, 2010). INTERVENTIONS: Patients in both groups received 3 mg of granisetron intravenously 30 minutes before the administration of anticancer drugs. In the aprepitant group, 125 mg of aprepitant was administered orally 60-90 minutes before the administration of the first moderately to highly emetogenic anticancer drug. On the following days, 80 mg of aprepitant was administered orally every morning. The mean administration duration of aprepitant was 3.3 days (range 3-6 days). MEASUREMENTS AND MAIN RESULTS: The primary objective was to evaluate the percentage of patients who achieved complete response (CR; no vomiting and none to mild nausea). The CR rate in the aprepitant group was significantly higher than that in the control group (48% vs 24%, p=0.02). Multivariate analysis showed that nonprophylactic use of aprepitant was associated with failure to achieve CR (odds ratio [OR] 2.92; 95% confidence interval [CI] 1.13-7.99, p=0.03). The frequency of abdominal pain was lower in the aprepitant group (9% vs 25%, p=0.03). Rates of other frequently observed adverse drug events were similar between groups. There was no significant difference in neutrophil engraftment (median 18 vs 17 days), platelet engraftment (median 32 vs 32 days), the incidence of acute graft-versus-host-disease (63% vs 55%, p=0.52), viral infection (74% vs 67%, p=0.49), or 1-year overall survival (63% vs 62%, p=0.90) between the two groups. CONCLUSIONS: The addition of aprepitant to granisetron increases the antiemetic effect without influencing transplantation-related toxicities in allo-HSCT.

PURPOSE: Antiemetic effectiveness and safety of aprepitant in patients with hematologic malignancy receiving multiday chemotherapy were evaluated. METHODS: All data were retrospectively collected from the Kyushu University Hospital's electronic medical record system. Patients age 20 years or older with hematologic malignancies who received multiday chemotherapy were included in the study. All patients received 3 mg of granisetron i.v. 30 minutes before chemotherapy administration. Patients in the aprepitant group received 125 mg of aprepitant orally 60-90 minutes before administration of the first moderately to highly emetogenic chemotherapy (day 1). On day 2 or thereafter, an 80-mg oral dose of aprepitant was administered in the morning for up to five days. The primary endpoint was the percentage of patients who achieved complete response (CR). RESULTS: A total of 42 patients were treated with aprepitant and granisetron as antiemetic prophylaxis between April and December 2010 (aprepitant group), and 40 patients were treated with only granisetron between March 1, 2009, and March 31, 2010, before the introduction of aprepitant. The percentage of patients who achieved CR in the aprepitant group was significantly higher than that in the control group (p = 0.01). Factors that were significantly associated with non-CR included the prophylactic use of aprepitant and chemotherapies containing ≥4 g/m(2)/day of cytarabine. The rates of adverse drug events (ADEs) did not significantly differ between groups. CONCLUSION: The addition of aprepitant to granisetron increased the antiemetic effect without influencing ADEs in patients treated with moderately to highly emetogenic multiday chemotherapy for hematologic malignancies.

Intravenous injection of bendamustine often causes venous irritation and also deteriorates the patient's quality of life. Thus, we evaluated the risk factors associated with venous irritation induced by bendamustine in patients with follicular lymphoma or mantle cell lymphoma. We also evaluated the effectiveness of intervention of changing the preparation procedure for bendamustine. All data were retrospectively collected from the electronic medical record system. In the initial analysis of the total 43 courses of bendamustine therapy, most patients (88%) were administered bendamustine with 250 mL of diluent according to the bendamustine package insert in Japan. The median concentration of bendamustine solution (0.56 mg/mL vs. 0.24 mg/mL) and the incidences of venous irritation (66% vs. 0%, p=0.01) were significantly different between the patients receiving bendamustine at 250 mL and 500 mL of diluent. Based on this result, we proposed changing the final volume of bendamustine dissolution from 250 to 500 mL, which is recommended in other countries. After this intervention, the incidence of venous irritation was significantly reduced from 58 to 20% (p=0.02). The incidence of venous irritation increased in a concentration-dependent manner (≤0.40 mg/mL: 6%; 0.41-0.60 mg/mL: 62%, p<0.001; >0.60 mg/mL: 75%, p<0.001). We conclude that a high concentration bendamustine solution is a risk factor for venous irritation and that 500 mL of diluent is ideal. To further reduce the incidence of venous irritation, the concentration of bendamustine solution is recommended to be 0.40 mg/mL or less.

For patients receiving high-dose chemotherapy, a 5-hydroxytryptamine 3 receptor antagonist combined with dexamethasone is a standard antiemetic therapy. Despite this prophylactic anti-emetic treatment, many patients still suffer from uncontrollable emesis. In this study, we retrospectively evaluated the antiemetic effectiveness and safety of aprepitant (a neurokinin-1 receptor antagonist) in addition to 5-HT3 antagonist in Japanese patients with hematologic malignancy receiving high-dose chemotherapy prior to autologous peripheral blood stem cell transplantation (auto-PBSCT). Twenty-six patients received aprepitant and granisetron (the aprepitant group), whereas, 22 patients received granisetron alone (the control group). All patients received 3 mg of granisetron intravenously 30 min before chemotherapy administration. Patients in the aprepitant group additionally received 125 mg of aprepitant 60-90 min before administration of the first moderately to highly emetogenic chemotherapy. On the next day or thereafter, 80 mg of aprepitant was administered in the morning until the last administration of moderately to highly emetogenic anticancer drugs. The percentage of patients who achieved complete response (CR), defined as no emesis with only grade 1-2 nausea, in the aprepitant group was significantly higher than that in the control group (42% vs. 5%, p=0.003). Logistic regression analysis showed that non-prophylactic use of aprepitant was significantly associated with non-CR. The frequencies of adverse drug events (ADEs) were not significantly different between two groups. In conclusion, the results of this study suggest that the addition of aprepitant to granisetron can improve the antiemetic effect without increasing ADEs in patients receiving high-dose chemotherapy prior to auto-PBSCT.

BACKGROUND: Neutropenia is one of the most frequent and dose-limiting toxicities in amrubicin (AMR) therapy. However, the predictive factors for the development of severe neutropenia in AMR therapy remain unknown. METHODS: The subjects were 61 advanced lung cancer patients treated with AMR monotherapy. All data were retrospectively collected from the electronic medical record system. A stepwise logistic regression analysis was performed to identify risk factors for grade 3-4 neutropenia. RESULTS: Of a total 61 patients, 50 were male and 11 were female. The median dose of AMR was 35.0 mg/m(2). The incidence of grade 3-4 neutropenia during the first course was 62%. In multivariate analysis, female gender (OR = 6.68; 95% CI 1.01-134.15; p = 0.049), higher AMR doses (40 mg/m(2) or more) (OR = 5.98; 95% CI 1.77-23.74; p = 0.003), and lower hematocrit values (OR = 2.04 per 5% decrease; 95% CI 1.04-4.38; p = 0.036) were significantly associated with severe neutropenia induced by AMR. CONCLUSION: The present results suggest that female gender, higher doses of AMR, and lower baseline hematocrit values are predictive factors associated with severe neutropenia induced by AMR in patients with advanced lung cancer. Patients who have these predictive factors should be monitored carefully and considered for early granulocyte colony-stimulating factor support.

OBJECTIVES: The aim of this study was to evaluate the effectiveness of prophylactic treatment with laxatives and antiemetics on the incidence of gastrointestinal adverse reactions such as constipation, nausea and vomiting in cancer patients who received oral opioid analgesics for the first time. METHODS: A multi-institutional retrospective study was carried out, in which 619 eligible hospitalized patients receiving oral opioid analgesics for cancer pain were enrolled from 35 medical institutions. The primary endpoint was the incidence of opioid-induced side effects in patients receiving prophylactic medication. Odds ratios of the incidence of adverse reactions in the absence or presence of premedication obtained from several institutions were subjected to a meta-analysis. RESULTS: Among 619 patients, the incidence of constipation was significantly lower in patients receiving laxatives, including magnesium oxide, as premedication than in those without them (34% vs. 55%, odds ratio=0.432, 95% confidence interval=0.300-0.622, P<0.001). However, the incidence of nausea or vomiting was similar regardless of prophylactic medication with dopamine D2 blockers. The results of the meta-analysis revealed that prophylactic laxatives significantly reduced the incidence of constipation (overall odds ratio=0.469, 95% confidence interval=0.231-0.955, P=0.037), whereas dopamine D2 blockers were not effective in preventing opioid-induced nausea or vomiting. DISCUSSION: We showed evidence for the effectiveness of premedication with laxatives for prevention of opioid-induced constipation. However, premedication with dopamine D2 blockers was not sufficient to prevent nausea or vomiting.

Oxaliplatin is a key drug for colorectal cancer, but it causes acute peripheral neuropathy (triggered by cold) and chronic neuropathy (sensory and motor neuropathy) in patients. Neurotropin, a non-protein extract from the inflamed rabbit skin inoculated with vaccinia virus, has been used to treat various chronic pains. In the present study, we investigated the effect of neurotropin on the oxaliplatin-induced neuropathy in rats. Repeated administration of oxaliplatin caused cold hyperalgesia from Day 5 to Day 29 and mechanical allodynia from Day 15 to Day 47. Repeated administration of neurotropin relieved the oxaliplatin-induced mechanical allodynia but not cold hyperalgesia, and inhibited the oxaliplatin-induced axonal degeneration in rat sciatic nerve. Neurotropin also inhibited the oxaliplatin-induced neurite degeneration in cultured pheochromocytoma 12 (PC12) and rat dorsal root ganglion (DRG) cells. On the other hand, neurotropin did not affect the oxaliplatin-induced cell injury in rat DRG cells. These results suggest that repeated administration of neurotropin relieves the oxaliplatin-induced mechanical allodynia by inhibiting the axonal degeneration and it is useful for the treatment of oxaliplatin-induced neuropathy clinically.

BACKGROUND: Oxaliplatin is a platinum-based chemotherapy drug characterized by the development of acute and chronic peripheral neuropathies. The chronic neuropathy is a dose-limiting toxicity. We previously reported that repeated administration of oxaliplatin induced cold hyperalgesia in the early phase and mechanical allodynia in the late phase in rats. In the present study, we investigated the involvement of NR2B-containing N-methyl-D-aspartate (NMDA) receptors in oxaliplatin-induced mechanical allodynia in rats. RESULTS: Repeated administration of oxaliplatin (4 mg/kg, i.p., twice a week) caused mechanical allodynia in the fourth week, which was reversed by intrathecal injection of MK-801 (10 nmol) and memantine (1 μmol), NMDA receptor antagonists. Similarly, selective NR2B antagonists Ro25-6981 (300 nmol, i.t.) and ifenprodil (50 mg/kg, p.o.) significantly attenuated the oxaliplatin-induced pain behavior. In addition, the expression of NR2B protein and mRNA in the rat spinal cord was increased by oxaliplatin on Day 25 (late phase) but not on Day 5 (early phase). Moreover, we examined the involvement of nitric oxide synthase (NOS) as a downstream target of NMDA receptor. L-NAME, a non-selective NOS inhibitor, and 7-nitroindazole, a neuronal NOS (nNOS) inhibitor, significantly suppressed the oxaliplatin-induced pain behavior. The intensity of NADPH diaphorase staining, a histochemical marker for NOS, in the superficial layer of spinal dorsal horn was obviously increased by oxaliplatin, and this increased intensity was reversed by intrathecal injection of Ro25-6981. CONCLUSION: These results indicated that spinal NR2B-containing NMDA receptors are involved in the oxaliplatin-induced mechanical allodynia.

Oxaliplatin is a platinum-based chemotherapy drug characterized by the development of acute and chronic peripheral neuropathies. Mexiletine, an orally available Na(+)-channel blocker, has widely been used in patients with chronic painful diabetic neuropathy. In the present study, we examined the effect of mexiletine on oxaliplatin-induced neuropathic pain in rats. Mexiletine (100, but not 10 and 30, mg/kg, p.o.) completely reversed both mechanical allodynia and cold hyperalgesia induced by oxaliplatin (4 mg/kg, i.p., twice a week). Lidocaine (30, but not 3 and 10, mg/kg, i.p.) also significantly relieved both pain behaviors. These results suggest that mexiletine may be effective in relieving the oxaliplatin-induced neuropathic pain clinically.

The importance of providing drug information has increased with the expansion of pharmaceutical care. In order to provide appropriate drug information to healthcare professionals, pharmacists have to understand their needs in this respect and be familiar with the procedure for answering typical questions. In the present study, we analyzed all of the questions (9,999) recorded by the drug information center of Kyushu University Hospital and the answers to them in the period from 2001 to 2007. The questions were from doctors (59.3%), pharmacists (21.5%), nurses (15.4%), and others (3.9%). The most frequent questions were on compatibility and stability of injections (18.8%), selecting drugs (13.2%), and dosage and administration (9.8%). We therefore made information on the compatibility and stability of injections available to other pharmacists via our intranet. We felt it was useful to clarify healthcare professionals' needs for drug information and develop a system enabling drug information to be used more easily.

Oxaliplatin is a key drug in the treatment of advanced metastatic colorectal cancer, but it causes acute peripheral neuropathy (acral paresthesias triggered by exposure to cold) and chronic neuropathy (abnormal of sensory and motor dysfunction). Oxaliplatin is metabolized to oxalate and dichloro(1,2-diaminocyclohexane)platinum (Pt(dach)Cl(2)). Although the chelating of Ca(2+) with oxalate eliminated from oxaliplatin is thought as one of the reasons for the neuropathy, there is little behavioral evidence. In this study, we investigated the involvement of oxalate in the oxaliplatin-induced peripheral neuropathy in rats. Oxaliplatin (4mg/kg, i.p., twice a week) induced cold hyperalgesia/allodynia (cold-plate and acetone tests) in the early phase, and mechanical allodynia (von Frey test) in the late phase. Oxalate (1.3mg/kg, i.p., twice a week) induced the cold hyperalgesia/allodynia in the early phase, but did not induce the mechanical allodynia. On the other hand, Pt(dach)Cl(2) (3.8mg/kg, i.p., twice a week) induced the mechanical allodynia in the late phase, but did not induce the cold hyperalgesia/allodynia. The pre-administration of calcium or magnesium (0.5mmol/kg, i.v.) before oxaliplatin or oxalate prevented the cold hyperalgesia but not mechanical allodynia. However, the treatment with calcium or magnesium after the development of neuropathy could not attenuate the cold hyperalgesia or mechanical allodynia. These findings suggest the involvement of oxalate in oxaliplatin-induced cold hyperalgesia but not mechanical allodynia, and usefulness of prophylactic treatments with calcium and magnesium on the acute peripheral neuropathy.

To provide effective and safe cancer treatment, the medical staff must form a team with patients and their family. Pharmacists have to be responsible for verifying chemotherapy prescription orders, mixing of anticancer drugs, management of adverse drug reactions, patient education, while providing drug information and participation in palliative care. To promote pharmacists who have acquired advanced knowledge and skills, The Japanese Society of Hospital Pharmacists started and educational program and established the certification of board-certified oncology pharmacy specialists (BCOPS) and board-certified pharmacists in oncology pharmacy (BCPOP). As of November 2007, 56 pharmacists were qualified as BCOPS.

In the present study, we evaluated the effectiveness of a new infusion set equipped with an in-line filter (5μm pore size) in removing precipitates of foreign matter forming during or after the preparation of infusion fluids. We also examined the ability of the new infusion set to prevent adverse effects associated with the intravenous injection of fluids containing crystalline precipitates in rats. The number of particles and their sizes were measured for two infusion fluids administered using a conventional infusion set without an in-line filter and the new infusion set, collecting the samples for measurement from the outlets of the respective infusion sets. One of fluids was a glycyrrhizin solution prepared from a glass ampoule injection, and the other etoposide solution prepared by diluting a preparation of this solution in a vial with saline. A number of particles (>10μm in size) were detected for both infusion fluids when administered by the conventional infusion set but none were detected in them when administered by the new infusion set. The intravenous injection of the precipitate-containing etoposide solution from the conventional infusion set to rats caused marked extravasation of plasma proteins and edema in lungs. Such adverse reactions did not occur with the new infusion set, demonstrating that it was effective in removing paniculate matter. It should thus be useful in intravascular fluid therapy from the safety point of view.

The incidence of hypersensitivity reactions is still a matter of serious concern during chemotherapy with paclitaxel, particularly in patients with ovarian cancer. We recently reported that intravenous injection of paclitaxel causes acute lung injury characterized by vascular hyperpermeability, edema and respiratory dysfunction in rats. In the present study, we investigated the influence of ovariectomy on the paclitaxel-induced acute lung injury in rats. Ovariectomy worsened paclitaxel-induced acute lung injury, which was reversed by 17beta-estradiol. The mRNA expression for endothelial nitric oxide synthase was reduced in lungs of ovariectomized rats. To determine the role for nitric oxide, we examined the effects of several agents that modulate nitric oxide concentration on the pulmonary response to paclitaxel. In ovary-intact rats, a nitric oxide synthase inhibitor NG-nitro-L-arginine methyl ester exaggerated paclitaxel-induced acute lung injury, while nitric oxide donors such as sodium nitroprusside and isosorbide dinitrate attenuated the lung injury. Sodium nitroprusside was also effective in alleviating the paclitaxel-induced acute lung injury in ovariectomized rats. These findings suggest that ovariectomy enhances the susceptibility to paclitaxel hypersensitivity, in which decrease in estrogen and subsequent reduction in nitric oxide synthesis may be involved.
