Relevance of pharmacoepidemiology to Nepal

Drug-related problems such as overuse of injectable drug products and antimicrobials, increased cost of drug therapy, polypharmacy, and adverse drug reactions (ADRs) are prevalent in the healthcare settings of Nepal. To date, no new drug development processes or clinical trials have been conducted in Nepal, despite the fact that studies of real life situations are an essential tool for monitoring medicine use. Pharmacoepidemiology (PE) is an important area that evaluates the effects of drug use in large populations. Data obtained from pharmacoepidemiological studies may highlight ways to reduce certain drug-related problems and provide reliable information on the safety profile of a drug. Moreover, clinicians and regulatory authorities may also use the data to make drug therapy decisions, drug regulation and policy development. Therefore, there is a great need to conduct appropriate pharmacoepidemiological studies that involve multiple regions and in various groups of the population of Nepal, to collect unbiased and reliable information on drug use.
