The hospital pharmacy department deals with the procurement, storage, preparation, dispensing, and distribution of drugs. It is responsible for forecasting drug demand, selecting reliable suppliers, manufacturing sterile preparations, quality control, dispensing drugs to outpatients, providing drug information, and maintaining liaison between medical and nursing staff. Drugs must be stored properly according to their temperature requirements, with refrigerated items kept between 2-8°C and frozen items between -10 to -25°C. Inventory management systems like FIFO, LIFO, and FEFO are used to ensure older products are used first before their expiration date. The chief pharmacist oversees the pharmacy staff and is responsible for regulatory compliance.
