Final answer:
The access to drugs at institutional facilities during absence depends on factors such as directly observed therapy and route of administration. Some drugs can be administered orally, while others may require parenteral administration. The choice of administration route depends on the drug's properties and the patient's condition.
Step-by-step explanation:
The access to drugs at institutional facilities during times of absence by the pharmacist depends on several factors. One possible solution is the implementation of directly observed therapy (DOT), which involves the supervised administration of medications to patients. This can be done either by patients visiting a healthcare facility or by healthcare providers administering medication at patients' homes or designated locations. Certain drugs can be administered orally, which is convenient for patients who can take them at home. However, drugs that are not easily absorbed from the gastrointestinal (GI) tract into the bloodstream may require parenteral administration (such as intravenous or intramuscular injection) in a health-care setting. The route of administration for a drug depends on its properties and the patient's condition.
