Laws governing how prescriptions are filled.

• A. Special narcotic license
• B. Food and Drug Act (Canada)
• C. Prescription regulations
• D. Drug schedules comparison

Answer: (C)

Filling prescriptions is governed by the rules that specify how dispensing is carried out in practice. Prescription regulations lay out the step-by-step requirements for pharmacists: what must appear on a prescription, who is authorized to dispense, how substitutions or dose changes are handled, how refills are managed, labeling and patient counseling requirements, and the necessary record-keeping. They translate broader drug laws into the everyday workflow you’ll encounter in a pharmacy, ensuring each dispensing action is safe, legal, and traceable, including the handling of controlled substances.

The other options address related but broader or more specific aspects. A special narcotic license is about obtaining permission to handle certain restricted drugs, but it doesn’t describe the general dispensing process. The Food and Drug Act provides overarching standards for drug safety, approvals, and labeling, not the day-to-day steps for filling a prescription. Drug schedules comparison deals with the classification and restrictions of drug types, not the actual procedure for dispensing.

So the best choice is prescription regulations because they directly govern the operational process of how prescriptions are filled.
