Kolbam - Cholic Acid

What is Kolbam - Cholic Acid and what is it used for?

Kolbam is a medicine containing cholic acid as an active ingredient.Cholic acid is a 'primary bile acid', a major component of bile (a liquid produced by the liver that aids in the digestion of fats).

Kolbam is authorized for the lifetime treatment of adults and children of at least one month of age who are unable to produce sufficient quantities of primary bile acids, such as cholic acid, due to specific genetic abnormalities resulting in a lack of following liver enzymes: sterol 27-hydroxylase, 2-methylacyl-CoA racemase or cholesterol 7Î ± -hydroxylase.

When primary bile acids are missing, the body produces abnormal bile acids that can damage the liver, with the risk of life-threatening liver failure. These disorders are known as "congenital defects of primary bile acid synthesis".

Because the number of patients with inborn defects of primary bile acid synthesis is low, the condition is considered 'rare', and Kolbam was designated an 'orphan medicine' (a medicine used in rare diseases) on 28 October 2009.

How is Kolbam used - Cholic Acid?

Kolbam can only be obtained with a prescription and treatment should be started and supervised by a doctor who specializes in the diseases treated with Kolbam.

Kolbam is available in capsules (50mg and 250mg). The daily dose is decided and adjusted during the course of treatment based on the blood (blood) and urinary levels of bile acids and the liver function of each patient. The maximum daily dose should not exceed 15 mg per kilogram of body weight.

Kolbam should be taken at approximately the same time each day, in conjunction with a meal. In the case of young children who are unable to swallow the capsules, the contents can be mixed with infant formula, expressed breast milk, mashed potatoes or fruit puree.

How does Kolbam - Cholic Acid work?

Cholic acid is one of the main primary bile acids produced by the liver. Cholic acid contained in Kolbam replaces the missing cholic acid in the patient's body. In this way, it helps reduce the production of abnormal bile acids and promotes the normal activity of bile in the digestive system, relieving the symptoms of the disorder.

What benefit has Kolbam - Cholic Acid shown during the studies?

Kolbam was studied in one main study involving 52 patients with inborn defects of primary bile acid synthesis, including 7 patients with lack of sterol 27-hydroxylase, 2-methylacyl-CoA racemase or cholesterol 7Î ± -hydroxylase. main efficacy parameters were changes in bile acid levels and liver function before and after treatment with Kolbam. Kolbam has been shown to reduce the amount of abnormal bile acids and improve liver function in the general population of patients with congenital defects. primary bile acid synthesis, and an improvement trend was observed in each individual enzyme deficiency, and these results were in line with clinical expectations and data from the medical literature.

Kolbam side effects are usually mild to moderate in severity and transient in nature. The most common side effects (which may affect up to 1 in 10 people) are peripheral neuropathy (nerve damage in the hands and feet), diarrhea, nausea, acid reflux (reflux of stomach acid into the mouth), esophagitis (inflammation of the mouth). esophagus), jaundice (yellowing of the skin and eyes), skin problems (lesions) and malaise.
