Essential drugs and registration of pharmaceuticals: the Sri Lankan experience.

Many factors influence the regulation of pharmaceuticals in a country. The essential drugs concept, formulated by the World Health Organization to assist developing countries in selecting appropriate drugs, also provides a basis for regulation. Sri Lanka has long regulated pharmaceuticals as part of its health policy. Over 70% of 3436 pharmaceutical product registrations were found to be drugs (or alternatives) named in the country's essential drugs list. This is despite the fact that product registrations are mainly for the private health care sector, and the list is for the state sector. The essential drugs concept therefore appears to have influenced the pharmaceuticals registered in Sri Lanka.
