The first academic subcommittee of the Japanese Society of Pharmaceutical Health Care and Sciences has a plan to create a guide on how to manage drug interactions in clinical settings. This review describes the information that forms the basis of the guide. As evidence for drug interactions with various mechanisms has not been clarified for all combinations, each case needs to be managed based on knowledge of clinical pharmacology regarding drug interactions. This article, part (3), shows the examples of both experimental and surveillance studies on drug interactions and also summarizes the points that require consideration when conducting surveillance studies.
The focus on drug interactions based on polypharmacy is increasing given that the number of elderly people continues to increase in Japan. Pharmacists are expected to contribute to the proper use of drugs through the assessment and performance of wet and dry studies.
