TANZANIA NATIONAL FORMULARY (TNF 2nd Edition)

Introduction

The Tanzania National Formulary (TNF) is published by the Ministry of Health through the Tanzania Food and Drugs Authority (TFDA). It aims at providing up-to-date, unbiased and evidence-based drug information which will promote safe, rational and effective use of drugs in the community.

The first edition of TNF was published in 1998. Since then great strides have been made in medicine and pharmacy such as emergency of new diseases, changes of treatment guidelines and occurrence of resistant microbes. These changes led to the development of new products and discovery of new adverse reactions and interactions. Therefore it has become necessary to revise and update the information of the TNF.

The second edition of TNF was published in 2005. Among many changes in this edition, it features new policy guidelines for treatment of malaria, management of HIV infection using Anti-Retroviral Drugs and entries of other drugs including new chapters on drugs for genitourinary disorders and diagnostics. New appendices on drugs use in hepatic and renal impairment had been added. Furthermore, drugs found to be associated with frequent adverse reactions and which had been withdrawn from the market, were omitted.
