Ursodeoxycholic Acid
Ursodeoxycholic acid (also known as UDCA or ursodiol) is the drug most commonly used to treat PBC. In fact, it is the only drug that is FDA approved for the treatment of PBC. Ursodeoxycholic acid was initially found to be beneficial for people with PBC in the early 1980s and became FDA approved in 1998. It is manufactured by Axcan Pharma(Mont Saint Hillaine, Quebec, Canada) under the brand name URSO. URSO is taken with food in oral pill form at a dosage of 13 to 15 milligrams per kilograms of body weight each day administered in four divided doses. Each pill is 250 milligrams. In November 2004 a new form of URSO will be available - known as URSO Forte. Each pill of URSO Forte will be 500 mg. Thus, this pill will allow for the ease of taking only one pill twice a day as the typical dosage. Actigall is another brand name for ursodeoxycholic acid. Actigall is marketed by Novartis (Summit, NJ) in tablets of 300mg. This drug is not FDA approved for the treatment of PBC, therefore its use is considered “off label”. Generic ursodeoxycholic acid is also available ñ known as ursodiol. Since ursodiol costs about 10 percent less than the brand name products (URSO and Actigall), many insurance companies prefer its use for the treatment of PBC.
