Essential medicines are those that satisfy the priority health care needs of the population, and are intended to be available at all times in adequate amounts, in the appropriate dosage forms with assured quality and affordable price to the individual and community. In developing countries scarce resources and increased demand account to a frequent shortage in drug supply. Therefore for best management, selection of drugs, competitive procurement methods, checking the quality, observing the stocks, optimum distribution and rational use are considered. Access to health care and essential medicines is part of the fulfillment of the fundamental right to health. Many factors define the level of access, such as financing, prices, distribution systems, appropriate dispensing and use of essential medicines. The price, availability and affordability of medicines are major determinants of access to treatment.
