The supply of antituberculosis drugs and national drugs policies

Abstract

The money necessary for purchasing antituberculosis drugs in a national programme comes from the Public Health Services budget, funds from the health insurance scheme (when it exists) and household budgets. The Public Health Services budget is on average $2–23 US per year and per person in low or middle income countries. Average drug consumption in these groups of countries was from $2–26 US per person in 1990. The number of patients to be treated depends on the annual risk of tuberculous infection (ARTI) and the case detection rate: it is the same when the ARTI is 1% and the detection rate 100%, and when the ARTI is 2% and the detection rate 50% of cases. The supply of antituberculosis drugs has a real cost representing around 3% of global drug consumption in low income countries and is always less than 1% of global drug consumption in middle income countries. In most developing countries it could be covered with the aid of national financial resources, on condition that it is integrated into a coherent national drugs policy aimed at guaranteeing the continued availability of essential drugs.
