What is Cholbam?

Cholbam is a prescription medicine that is used to treat certain bile acid problems caused by single enzyme defects (SEDs). It is used to treat peroxisomal disorders like Zellweger spectrum disorders.

Description

Cholic acid is a bile acid produced by the liver where it is synthesized from cholesterol. The chemical formula is C 24405, the molecular weight is 408.57 and the chemical structure is:

Chemical Structure

Cholic acid is a white to off-white powder. It is practically insoluble in water and in 0.1 M HCl at 20°C and is sparingly soluble in 0.1 M NaOH at 20°C. It is soluble in glacial acetic acid, alcohols, and acetone. A saturated solution in water at 20°C has a pH of 4.4.

CHOLBAM capsules contain 50 mg or 250 mg of cholic acid as the active ingredient in size 2 Swedish orange or size 0 white opaque gelatin capsules, respectively. Inactive ingredients in CHOLBAM include silicified microcrystalline cellulose, magnesium stearate, and hard gelatin capsules. The size 2 shells contain gelatin, red iron oxide and titanium dioxide, and the size 0 shells contain gelatin and titanium dioxide. CHOLBAM is administered orally.

 Mechanism of Action

Cholic acid is a primary bile acid synthesized from cholesterol in the liver. In bile acid synthesis disorders due to SEDs in the biosynthetic pathway, and in PDs including Zellweger spectrum disorders, deficiency of primary bile acids leads to unregulated accumulation of intermediate bile acids and cholestasis. Bile acids facilitate fat digestion and absorption by forming mixed micelles and facilitate absorption of fat-soluble vitamins in the intestine.

Endogenous bile acids including cholic acid enhance bile flow and provide the physiologic feedback inhibition of bile acid synthesis. The mechanism of action of cholic acid has not been fully established; however, it is known that cholic acid and its conjugates are endogenous ligands of the nuclear receptor, farnesoid X receptor (FXR). FXR regulates enzymes and transporters that are involved in bile acid synthesis and in the enterohepatic circulation to maintain bile acid homeostasis under normal physiologic conditions.
