Pharmacies in hospitals change greatly from community pharmacies. various pharmacists in hospital pharmacies can have more complex clinical medication managing issues whereas pharmacists in community pharmacies frequently have extra complex business and customer relations issues.

Because of the density of medications with specific indications, efficiency of treatment regimens, protection of medications (i.e., drug interactions) and patient agreement issues ( in the hospital and at home) many pharmacists involved in hospitals gain more education and training after pharmacy school throughout a pharmacy practice care order and sometimes followed by another residency in a specific area. Most pharmacists are frequently referred to as clinical pharmacists and they often concentrate in various disciplines of pharmacy. For illustration, there are pharmacists who focus in haematology/oncology, HIV/AIDS, transferable disease, critical care, emergency medicine, toxicology, nuclear pharmacy, pain management, psychiatry, anticoagulation clinics, herbal medicine, neurology/epilepsy management, paediatrics, neonatal pharmacists and more.

Hospital pharmacies can regularly be initiate in the place of the hospital. Hospital pharmacies generally stock a larger range of medications, with more expert medications, than would be possible in the community setting. Most of the hospital medications are unit-dose, or a single dose of medicine. Hospital pharmacists and trained pharmacy technicians composite sterile products for patients with total parenteral nutrition (TPN), and other medications specified intravenously. This is a composite process that requires sufficient training of personnel, quality assurance of products, and adequate facilities. some hospital pharmacies have decided to outsource high risk arrangements and some other compounding functions to companies who concentrate in compounding.
