The Formulary aims to provide standard information on drugs. And it targets all health professionals involved in patient care, training and research and others.

The District Hospital formulary has also been extensively refered. The formulary contains detailed information on each pharmaco-therapeutic class of drugs and specific information for each drugs including indication, caution, drug interaction, contraindication, side effect, dose and administration and information on storage condition. The formulary also contains general notes on good prescribing and dispensing practices, and supplementary information as appendixes. The formulary is designed as a digest for rapid reference and it may not always include all the information necessary for prescribing and dispensing. And by no means it does substitute standard treatment guidelines. We hope, that this formulary will be of assistance in providing useful information to the health workers and in promoting the rational use of drugs and as result proviosn of quality health services.
