Use and quality of antimalarial drugs in the private sector in Viet Nam.

摘要

This study examines the use and quality of antimalarial drugs in the growing private sector of Viet Nam. The practices of drug vendors (called alternative treatment providers (ATPs)) as well as their stocks and the quality of drugs sold by them, and the local production and distribution of antimalarials were investigated. Antimalarials were sold by the vast majority of ATPs, almost all the common antimalarials being available for sale. The practices and indications for sale, however, varied. Underdosing for malaria was frequent in all three provinces studied, and lack of knowledge of the appropriate regimen for cure was common among the drug-sellers. Samples of antimalarials were collected from ATP outlets in the three provinces, and the drugs were assessed for their contents and expiry date by the Institute of Drug Quality Control in Hanoi. Of the 218 samples of drugs examined by the Institute, over 96% met the quality requirements. However, a 10% sample of these drugs were independently assessed by WHO and revealed a different picture: 70% of them failed to meet the standard specifications required. There is therefore an urgent need to improve the capability and monitoring procedures of bodies involved in assessing and regulating drugs in Viet Nam.
