Abstract
Patients who received pharmacist-conducted counseling in the medical ward of the Second Department of Internal Medicine, Gifu University Hospital, were monitored for drug use from August 1992 to May 1994. The average number of drugs received by patients who were administered digitalis, theophylline, warfarin or adrenocorticoids was 8.0, and the average number of drugs received by patients who were administered the other drugs without these 4 drugs was 5.8. It was shown that 71.4% of patients given digitalis, theophylline, warfarin or adrenocorticoids were concomitantly administered drugs which were suspected the drug interactions, whereas this condition arose in 33.3% of patients given other drugs. This finding suggests that the risk of incurring on adverse drug reaction was increased in patients receiving these drugs.
