What does TR stand for in medication release terms?

• A. timed release
• B. topical release
• C. trigger release
• D. targeted release

Answer: (A)

Timed release means the medicine is designed to release the active ingredient gradually over a period of time, rather than all at once. This helps keep drug levels steadier in the body and can reduce how often you need to take the medicine. It’s different from topical release, which refers to applying the drug to the skin or a mucosal surface for local effect; from trigger-release, where release starts in response to a stimulus like pH or temperature; and from targeted release, which aims the drug at a specific tissue or organ. An example is a once-daily tablet that releases the drug slowly over 24 hours to provide steady relief.
