Step 1: Understanding the Concept:
The Pharmacy and Therapeutics Committee (PTC) is an advisory group of doctors, pharmacists, and other health professionals in a hospital.
Step 2: Detailed Explanation:
1. Hospital Formulary: This is a list of drugs that the hospital stocks and allows doctors to prescribe.
2. Selection: The PTC's primary role is to evaluate scientific data to decide which drugs are safe, effective, and cost-efficient. They add or remove drugs from the formulary based on this evidence.
3. Safety: They also monitor adverse drug reactions (ADRs) and medication errors within the hospital.
4. Others: Purchasing is done by the procurement department, and dispensing is done by pharmacists.
Step 3: Final Answer:
The clinical and administrative management of the drug formulary is the core responsibility of the PTC.
