Background : The discipline of clinical pharmacology has been trying to improve the efficacy and safety of drug therapy on a scientific basis, and also to attain rational prescription. Clinical pharmacology has also played the vital role in new drug development. It is clear that medical students should receive a sound education in clinical pharmacology during their undergraduate course so that they can easily understand current therapies as well as evaluate and assimilate new therapeutic advances in the future. The current status of clinical pharmacology education in Korean medical schools was therefore investigated. Method : A nation-wide survey on the current status of clinical pharmacology education were conducted in 41 Korean medical schools. Results : 38 (92.7%) schools responded to the questionaire on the current status of clinical pharmacology education. Only about one fourth (26.3%) of respondents were teaching clinical pharmacology as a separate discipline. In case of separate clinical pharmacology course, an average time of clinical pharmacology education was 13.5 hours and the education was done most frequently during the 4th-year grade of medical curriculum. The main subjects taught most frequently were clinical pharmacokinetics, therapeutic drug monitoring, drug use in elderly and children, drug use in kidney disease patients, etc. In case of 25 medical schools in which clinical pharmacology lecture is included as just one part of existing pharmacology course, the average time of clinical pharmacology lecture was only 6.4 hours. Fifteen schools among 28 schools (53.6%) which do not have an independent clinical pharmacology course expressed the future plan to have an independent clinical pharmacology course of average 16.9 hours. Conclusion : These data indicated that there are severe deficiency of clinical pharmacology teaching in Korean medical schools, and every effort is urgently required to encourage the education of clinical pharmacology in undergraduate medical curriculum in Korea.
