1. What is Proursan and what is it used for
Proursan is a medicine that contains ursodeoxycholic acid as the active substance. It is one of the bile acids, which occur naturally in human bile. After oral administration, the substance is absorbed in the small intestine and transported to the liver with the blood, undergoing constant enterohepatic circulation, resulting in the saturation of bile with ursodeoxycholic acid. The medicine reduces the secretion of cholesterol into bile, prevents the formation of gallstones, and causes their dissolution.
Indications for use:
- Primary biliary cirrhosis in patients without decompensated liver cirrhosis
- Treatment of liver diseases of various etiologies in the absence of indications for other recommended therapies.
- Gastritis caused by bile reflux.
- Dissolution of cholesterol gallstones with a diameter not exceeding 15 mm, permeable to X-rays, in patients in whom, despite the presence of stones, the function of the gallbladder is preserved.
Children and adolescents
Functional disorders of the liver and bile ducts associated with cystic fibrosis in children and adolescents aged 6 to 18 years.
2. Important information before taking Proursan
When not to take Proursan
- if you are allergic to bile acids (i.e., ursodeoxycholic acid) or to any of the other ingredients of this medicine (listed in section 6);
- if you have acute cholecystitis and biliary tract inflammation;
- if you have a blockage of the common bile duct or the cystic duct;
- if you have frequent pain in the upper abdomen, similar to colic (biliary colic episodes);
- if you have calcified gallstones that give a shadow in X-rays;
- if you have reduced gallbladder contractility.
In case of doubts about the above symptoms, you should consult a doctor. If you have had any of the above symptoms in the past, you should inform your doctor.
Children and adolescents
Failed surgical anastomosis of intrahepatic bile ducts with the small intestine or narrowing of the bile ducts without proper bile flow.
Warnings and precautions
Proursan should be taken under medical supervision.
During treatment, your doctor may recommend monitoring liver function parameters every 4 weeks for the first 3 months, and then every 3 months.
If you experience chronic diarrhea, you should immediately consult your doctor, as it may be necessary to reduce the dose or discontinue treatment with Proursan.
Proursan and other medicines
You should tell your doctor or pharmacist about all medicines you are taking or have recently taken, as well as any medicines you plan to take.
Proursan may reduce the effectiveness of the following medicines:
- cholestyramine, colestipol (a medicine that lowers blood cholesterol levels) or aluminum hydroxide, aluminum compounds (aluminum oxide) containing antacids. If it is necessary to take a medicine containing one of these substances, you should take it 2 hours before or 2 hours after taking Proursan.
- ciprofloxacin, dapsone (an antibiotic), nifedipine (used to lower blood pressure), and other medicines metabolized in a similar way. If necessary, your doctor may adjust the doses of these medicines.
Proursan may enhance the effects of the following medicines:
- cyclosporine (reduced effect on the immune system). In patients treated with cyclosporine, your doctor may recommend monitoring its blood levels and, if necessary, reducing the dose of cyclosporine.
If you are taking Proursan to dissolve gallstones, you should inform your doctor about any medicines you are taking that contain estrogen hormones or cholesterol-lowering medicines, such as clofibrate. These medicines may stimulate the formation of stones, which is contrary to the effect of Proursan therapy.
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, you should ask your doctor or pharmacist for advice before taking this medicine.
Proursan should not be taken during pregnancy, unless your doctor considers it absolutely necessary.
Women of childbearing age should take this medicine only with the simultaneous use of effective contraceptive methods. Non-hormonal methods or low-estrogen oral contraceptives are recommended. However, in patients taking Proursan to dissolve gallstones, non-hormonal methods should be used, as oral hormonal contraceptives may exacerbate gallstones.
Before starting treatment, you should check if you are not pregnant.
There is insufficient data on the use of Proursan in pregnant women, especially during the first trimester. Animal studies have shown a risk of fetal damage in early pregnancy.
Proursan should not be taken during breastfeeding. There is insufficient data on the penetration of ursodeoxycholic acid into breast milk. If treatment with Proursan is necessary, you should stop breastfeeding.
Driving and using machines
There are no known reports of the effect of the medicine on the ability to drive and use machines.
3. How to take Proursan
