What is the prescription for drug dose, frequency, and duration called?

• A. Dose
• B. Dosage
• C. Dosage regimen
• D. Drug administration

Answer: (C)

The main idea here is understanding how a drug is used over time. The plan that specifies how much is given, how often, and for how long is called the dosage regimen. It combines the amount per administration (the dose), the timing (frequency), and the total course (duration) into one prescription so the therapy is consistent and safe. A dose refers to the amount given at one time, and drug administration is simply the act of giving the medication. Dosage is a general term for the amount to be given, but it doesn’t inherently include the schedule or the total treatment length. The dosage regimen, however, clearly defines all three components—dose, frequency, and duration—so it’s the appropriate term for the prescription. For example, 500 mg taken three times daily for seven days by mouth is a dosage regimen.
