Abstract
Part of the impact of the war in ex-Yugoslavia and especially Bosnia and Herzegovina was to limit the supply of therapeutic drugs they had used before the war. The difficulties encountered made the health care system temporarily dependent on humanitarian assistance agencies which applied the concept of essential drugs; and, after initial difficulties, national health staff adapted to the need to prescribe from a very limited range of drugs. Meanwhile, national drug policy and procurement and prescribing practices were reviewed by working groups and a national List of Essential Drugs was drawn up by national experts with international support. This list has now been passed into legislation.
