Controlled release (CR), sustained release, extended release or long acting products are designed for continuous release over time.

• A. Controlled release
• B. Semisolid medications
• C. Topical
• D. Creams

Answer: (A)

Controlled release formulations are designed to release a drug gradually over an extended period, creating steadier levels in the body and reducing how often a dose must be taken. This continuous release helps maintain therapeutic effect and can improve adherence and minimize peaks and troughs in drug levels. The other terms describe where or how the drug is delivered (semisolid forms like ointments, topical application, or creams) rather than how the drug is released over time, so they don’t address the ongoing, timed release aspect. It’s also important to remember that CR tablets should be swallowed whole; crushing or chewing them can release the drug too quickly and increase risk of side effects or toxicity.
