Final answer:
Closed door pharmacies are pharmacies that primarily cater to institutional settings such as hospitals and clinics, providing medications and pharmaceutical services to patients in these healthcare facilities.
Step-by-step explanation:
In the United States, closed door pharmacies are pharmacies that operate without a retail storefront and primarily cater to institutional settings such as hospitals, nursing homes, and clinics. These pharmacies do not typically serve the general public and instead focus on providing medications and pharmaceutical services to healthcare facilities.
An example of a closed door pharmacy is a hospital pharmacy, which dispenses medications to inpatients, outpatients, and emergency departments within the hospital.
Closed door pharmacies play a crucial role in ensuring that patients in healthcare institutions receive the appropriate medications and pharmacy services in a safe and efficient manner.
