The document discusses drug revolving funds (DRF) as a system used at the College of Health Sciences at Evangel University in Akaeze. DRF uses revenue from drug sales to purchase new drugs and ensure availability. The goal of DRF is to provide safe, quality drugs at affordable prices. Seed money from government or donors is used to initially purchase essential medicines, which are then dispensed at prices to replenish the stock and ensure continuous supply. DRF was adopted in 1988 with support from organizations like WHO and DFID. It is important for healthcare delivery in developing countries for access to essential medicines.
