ALVIMOPAN

Gastrointestinal Approved 2019-12-19

Alvimopan is indicated to accelerate the time to upper and lower gastrointestinal recovery following surgeries that include partial bowel resection with primary anastomosis. It is used to manage postoperative ileus, a multifactorial impairment of gastrointestinal motility that commonly follows abdominal surgery. By accelerating the return of normal bowel function, alvimopan can help reduce the duration of hospital stays.

How ALVIMOPAN Works

Alvimopan is a selective, peripherally acting µ-opioid receptor antagonist (PAMORA). It competitively binds to µ-opioid receptors in the gastrointestinal tract, blocking the inhibitory effects of both endogenous opioids released during surgical stress and exogenous opioid analgesics. Because its ability to cross the blood-brain barrier is highly limited at therapeutic doses, alvimopan antagonizes the peripheral effects of opioids on gut motility without reversing their central analgesic effects. This helps maintain gastrointestinal contractility and speeds recovery of the digestive system.

ALVIMOPAN Boxed Warning

POTENTIAL RISK OF MYOCARDIAL INFARCTION WITH LONG-TERM USE: FOR SHORT-TERM HOSPITAL USE ONLY There was a greater incidence of myocardial infarction in alvimopan-treated patients compared to placebo-treated patients in a 12-month clinical trial, although a causal relationship has not been established. In short-term trials with alvimopan, no increased risk of myocardial infarction was observed [see Warnings and Precautions ( 5.1 )] . Because of the potential risk of myocardial infarction with long...
