Description

Livmarli (maralixibat) is a prescription medicine used to treat cholestatic pruritus (itch) in patients with Alagille syndrome 3 months of age and older. Alagille syndrome is a genetic disorder that affects the liver, heart, and other organs. Cholestatic pruritus is a common symptom of Alagille syndrome and is caused by a buildup of bile acids in the blood.

Drug class

Livmarli is an ileal bile acid transporter (IBAT) inhibitor. IBAT is a protein in the intestines that helps to reabsorb bile acids. By inhibiting IBAT, Livmarli reduces the reabsorption of bile acids and increases their excretion in the feces. This helps to lower the levels of bile acids in the blood and relieve cholestatic pruritus.

Indications

Livmarli is indicated for the treatment of cholestatic pruritus in patients with Alagille syndrome 3 months of age and older.

Mechanism of action

Livmarli works by inhibiting the ileal bile acid transporter (IBAT). IBAT is a protein in the intestines that helps to reabsorb bile acids. By inhibiting IBAT, Livmarli reduces the reabsorption of bile acids and increases their excretion in the feces. This helps to lower the levels of bile acids in the blood and relieve cholestatic pruritus.

Dosage and administration
