Objective: The government has been promoting further contribution to home care by pharmacists since almost all homebound patients are prescribed more than one medicine. However, little information is available on the adverse drug reactions (ADRs) in home care setting. This study was conducted to describe the ADRs reported by pharmacists in home care and examine factors related to their reports.
Design: Questionnaire survey
Methods: We requested patient-visiting pharmacists at community pharmacies throughout Japan to answer questions about their patients. Main questions included patient characteristics, number of drugs taken, presence of ADRs and details, and pharmacists' workload related to home-visiting.
Results: Data on 5,447 patients were collected from 1,890 pharmacies. The percentage of patients in whom the visiting pharmacists found ADRs was 14.4%. ADRs reported in 10 or more cases covered 12 categories, accounting for 85.2% of all ADRs. The top five categories were: dizziness, grogginess, or lightheadedness; gastrointestinal disturbances; clinical test value abnormality; altered mentation; and cutaneous symptoms. In seven of the 12 ADR categories, central nervous system drugs such as sleeping pills, antianxiety drugs, and psychoneurosis drugs were in the top three suspected drugs. Additionally, patients' gender, residential situation, and the number of drugs taken were implied as factors related to ADRs.
Conclusion:Our study indicated that, while the percentage of ADR occurrences in home-visiting service in Japan was at the same level as outpatients in other countries, drugs for the central nervous system accounted for a higher percentage of suspected drugs. Further, occurrence of ADRs was associated with the use of more than 6 concomitant drugs. These results suggest that physicians and pharmacists need to collaborate in decreasing the number and dose of central nervous system drugs.

BACKGROUND:
The current study aimed to investigate the hepatoprotective effects of Sasa veitchii extract (SE) on carbon tetrachloride (CCl)-induced liver fibrosis in mice.
METHODS:
Male C57BL/6J mice were intraperitoneally injected with CCl dissolved in olive oil (1 g/kg) twice per week for 8 weeks. SE (0.1 mL) was administered orally once per day throughout the study, and body weight was measured weekly. Seventy-two hours after the final CCl injection, mice were euthanized and plasma samples were collected. The liver and kidneys were collected and weighed.
RESULTS:
CCl administration increased liver weight, decreased body weight, elevated plasma alanine aminotransferase, and aspartate aminotransferase and increased liver oxidative stress (malondialdehyde and glutathione). These increases were attenuated by SE treatment. Overexpression of tumor necrosis factor-α was also reversed following SE treatment. Furthermore, CCl-induced increases in α-smooth muscle actin, a marker for hepatic fibrosis, were attenuated in mice treated with SE. Moreover, SE inhibited CCl-induced nuclear translocation of hepatic nuclear factor kappa B (NF-κB) p65 and phosphorylation of mitogen-activated protein kinase (MAPK).
CONCLUSION
These results suggested that SE prevented CCl-induced hepatic fibrosis by inhibiting the MAPK and NF-κB signaling pathways.
