What is a common purpose for inactive ingredients found in OTC medicines?

• A. To improve taste
• B. To increase the amount of active ingredient
• C. To reduce packaging costs
• D. To support product stability

Answer: (C)

Inactive ingredients in OTC medicines are added to keep the product safe, effective, and usable over time, rather than to treat symptoms. A common purpose is to support product stability. These components help preserve potency and safety by including preservatives to prevent microbial growth, antioxidants to stop chemical degradation, and buffering agents to maintain the right pH. They also aid in texture, disintegration, and delivery, but stability is a broad, fundamental reason these ingredients are included across many formulations. Taste masking or flavoring can be important in some oral medicines, but it’s not universal. Increasing the amount of active ingredient isn’t achieved by inactive ingredients, and reducing packaging costs isn’t a typical goal of formulation components.
