Pharmacology

Indication

Used to accelerate the time to upper and lower gastrointestinal recovery following partial large or small bowel resection surgery with primary anastomosis. Also investigated for use in the treatment of pain (acute or chronic).

Associated Therapies

To accelerate the time to upper and lower gastrointestinal recovery following surgeries that include partial bowel resection with primary anastomosis

Pharmacodynamics

Not Available

Mechanism of action

Alvimopan competitively binds to mu-opioid receptor in the gastrointestinal tract but, unlike methylnaltrexone which relies upon it ionic charge, alvimopan owes its selectivity for peripheral receptors to its pharmacokinetics. Alvimopan binds to peripheral mu-receptors with a Ki of 0.2 ng/mL.

Absorption

Alvimopan's high affinity for the peripheral mu-receptor leads to slower absorption dependent on dissociation from the receptor and subsequently low oral bioavailability of less than 7%.

Volume of distribution

30±10 L

Protein binding

80% to 90% bound in after entering systemic circulation.

Metabolism

Alvimopan is primarily metabolized by intestinal flora to an active metabolite although it has no clinically significant contribution to the effects of the drug.

Route of elimination

Biliary secretion was considered the primary pathway for alvimopan elimination. Unabsorbed drug and unchanged alvimopan resulting from biliary excretion were then hydrolyzed to its ‘metabolite’ by gut microflora. Feces (via biliary excretion) & urine (35%)

Half life

10 to 17 hours (gut metabolite: 10 to 18 hours)

Clearance

402 ± 89 mL/min
