A pharmacy located in a hospital that services patients within the hospital and ancillary areas only is called a:

An inpatient pharmacy is specifically designed to serve patients who are admitted to a hospital. This type of pharmacy provides medications and pharmaceutical services primarily to individuals receiving care in the hospital, including those in surgical wards, emergency departments, and other inpatient units.

Inpatient pharmacies are equipped to handle the unique medication needs of hospitalized patients, such as preparing sterile products and managing medication therapy that may require close monitoring. The delivery of medications is often tightly integrated with the healthcare team within the hospital to ensure that patients receive timely and appropriate treatments.

In contrast, outpatient pharmacies typically service individuals who are discharged from hospitals or those who visit for scheduled appointments or refills but are not currently admitted. A nursing unit refers to a specific area within the hospital where nurses provide care, while a clinic pharmacy serves patients seeking outpatient services and medications in a more general healthcare setting.

Thus, the focus of an inpatient pharmacy on serving those who are currently hospitalized distinguishes it clearly from the other types of pharmacies mentioned.
