Immediate-Release (IR) Morphine

• Pharmacology: These formulations dissolve quickly, reaching the central nervous system in about 30 minutes. However, due to rapid hepatic metabolism (the “first-pass effect”), only about 40% of an oral dose reaches systemic circulation.
• Dosing: Effects typically last 2 to 4 hours, requiring frequent administration (often every 4 hours) to maintain relief. This makes IR forms ideal for short-term recovery, such as post-surgical pain or trauma.

Important Safety Note: Morphine carries a high risk of addiction, abuse, and life-threatening breathing problems (respiratory depression). It should only be used under strict medical supervision. {1}
