Hospital pharmacies are within the premises of a hospital which provides a huge quantity of medications per day which is allocated to the main entrance, wards and to intensive care unit according to medication schedule. Hospital pharmacists were mostly engaged in traditional pharmaceutical activities such as dispensing and manufacturing. Then, the increasing range and sophistication of medicines available, awareness of medication errors and the widespread use of ward-based prescription charts brought pharmacists out of the dispensary and on to the wards in increasing numbers. Pharmacist and trained pharmacy technicians compound sterile products for patients including total parenteral nutrition (TPN), and other medications given intravenously e.g. Neonatal antibiotics and chemotherapy this is a complex process that requires adequate training of personnel, quality assurance of products, and adequate facilities. Hospital pharmacies typically provide medications for the hospitalized patients only, and are not retail establishments. They typically do not provide prescription service to the public.
