In pharmacology, what does dosage form refer to?

• A. The chemical composition of the drug
• B. The form in which a drug is administered
• C. The drug's color
• D. The drug's packaging

Answer: (B)

Dosage form means the physical form in which a drug is prepared and given to a patient, such as a tablet, capsule, oral solution, injectable, ointment, or transdermal patch. This is about how the drug is delivered, not its chemical makeup, color, or packaging. The dosage form determines practical aspects like how the drug is absorbed, how quickly it acts, how stable it is, and how easy it is for a patient to use. The same active ingredient can appear in multiple dosage forms, and choosing the right form affects both effectiveness and adherence. So the form in which a drug is administered best describes what dosage form means.
