What does SR stand for in medication formulations?

• A. Sublingual route
• B. Rectum or rectal route
• C. Sustained release
• D. Subcutaneous route

Answer: (C)

SR in medication formulations refers to how the drug is released over time. It stands for sustained release, meaning the dosage form is designed to release the active ingredient gradually rather than all at once. This slow release helps keep drug levels in the bloodstream more stable and can reduce how often a patient needs to take the medicine. The other terms point to routes of administration, not release profiles: sublingual route is absorption under the tongue, rectal route is through the rectum, and subcutaneous route is an injection under the skin. These describe how the drug enters the body, not how it is released from the dosage form.
