A pharmacy system is an organized system within a hospital or healthcare institution that is responsible for the selection, procurement, storage, preparation, distribution, dispensing, and proper use of medicines. It ensures that the right medicine reaches the right patient in the right dose, at the right time, and through the appropriate route. The pharmacy system also helps maintain drug quality, prevent medication errors, control costs, and promote rational use of medicines. In a hospital, the pharmacy is an important link between doctors, nurses, patients, suppliers, and other healthcare professionals. Drug distribution refers to the process by which medicines are supplied from the hospital pharmacy to different patient-care areas or directly to patients. An efficient drug distribution system ensures continuous availability of medicines and reduces wastage, misuse, expiry, and medication errors. The system generally begins with the selection and procurement of medicines and ends with administration to the patient and monitoring of their use. The major steps of a hospital drug distribution system can be represented by the following flow diagram: Drug Selection → Procurement → Receiving → Storage → Prescription → Pharmacy Processing → Dispensing → Distribution to Patient/Care Unit → Administration →
