62.5 mg film-coated tablets
1. What Bosentan Actavis is and what it is used for
Bosentan Actavis tablets contain bosentan , which blocks a naturally occurring hormone called endothelin-1 (ET-1) which causes the blood vessels to become narrow. Bosentan Actavis, therefore, causes the blood vessels to dilate and belongs to a group of medicines called ‘endothelin receptor antagonists’.
Bosentan Actavis is used to treat:
- Pulmonary arterial hypertension (PAH): PAH is a disease that leads to severe narrowing of the blood vessels in the lungs. As a result, high blood pressure occurs in the blood vessels in the lungs (pulmonary arteries) that transport blood from the heart to the lungs. This pressure reduces the amount of oxygen that can enter the blood in the lungs, making physical activity more difficult. BosentanActavis dilates the pulmonary arteries and makes it easier for the heart to pump blood through them. This lowers blood pressure and relieves symptoms.
Bosentan Actavis is used for treating patients with pulmonary arterial hypertension(PAH) class III to improve their ability to work (the ability to perform physical activity) and their symptoms. The class shows the severity of the disease, where class III means that physical activity is markedly limited. Some improvements have also been shown in patients with PAH class II. Class II means that physical activity is easily limited. PAHs for which Bosentan Actavis is used may be:
- primary (without identified cause or hereditary)
- caused by scleroderma (also called systemic sclerosis, a disease with abnormal growth of connective tissue that supports the skin and other organs)
- caused by congenital (congenital) heart defects where shunts (abnormal connections) cause an abnormal blood flow through the heart and lungs.
- Digital sores (sores on the fingers and toes) in adult patients with a condition called scleroderma. Bosentan Actavis reduces the number of new wounds on fingers and toes that occur.
Bosentan contained in Bosentan Actavis may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions and always follow their instructions.

Checks that your doctor will do during treatment

These will be taken once a month during the first four months of treatment and then once every three months thereafter, as patients taking Bosentan Actavis may develop anemia .

Driving and using machines
