What are product line extensions?

• A. A new indication.
• B. New active ingredient.
• C. Dosage forms in which the physical form or strength changes, but not the use or indication.
• D. A different brand name.

Answer: (C)

Product line extensions involve adding variations within an existing drug line that keep the same active ingredient and the same therapeutic use, but change how the drug is delivered or how much you take. It’s about offering different dosage forms or strengths to fit patient needs, without altering what the drug treats. So, changing the physical form (tablet, capsule, liquid) or providing different strengths while keeping the indication the same is a line extension. This is different from introducing a new indication (a new use for the drug), a new active ingredient (a different molecule entirely), or simply changing the brand name.
