Alvimopan is an opioid receptor antagonist used to reduce the duration and severity of postoperative ileus following partial large or small bowel resection surgery. It works by blocking the effects of opioids on the gastrointestinal tract, allowing the intestines to return to normal function more quickly. Alvimopan is given as a single dose, taken orally one hour before the start of surgery and then again 12 hours later. It is not recommended for use in patients who are hypersensitive to alvimopan or any other ingredients in the formulation.
Alvimopan, also known by the brand name Entereg, is a medication used to accelerate the recovery of bowel function following certain types of abdominal surgery. It works by counteracting the constipating effects of opioid pain medications commonly used after surgery.
Here's a breakdown of its key aspects:
Function:
- Peripherally acting μ-opioid receptor antagonist: It specifically targets opioid receptors located in the gastrointestinal tract, preventing them from being activated by opioids.
- This prevents the opioid-induced slowing down of gut motility, leading to faster bowel movement and shorter hospital stays.
Applications:
- Postoperative ileus: This is a condition where the bowels stop working normally after surgery, leading to constipation and abdominal discomfort. Alvimopan helps reduce the duration and severity of postoperative ileus following procedures involving:
- Small or large bowel resection (removal of part of the intestine) with primary anastomosis (reconnecting the remaining parts)
- Radical hysterectomy (removal of the uterus and surrounding tissues)
Administration:
- Taken orally, typically as a capsule.
- Dosage and duration of treatment are determined by the doctor based on individual needs.
Important points to remember:
- Alvimopan is not a pain reliever and should not be used for that purpose.
- It may cause side effects such as nausea, vomiting, abdominal pain, and headache.
- It can interact with other medications, so it's crucial to inform your doctor about all medications you're taking before starting alvimopan.
- Pregnant or breastfeeding women should not take alvimopan without consulting their doctor.
