The Bosentan Accordpharma tablets contain bosentan, which blocks the natural hormone called endothelin-1 (ET-1), and causes narrowing of the blood vessels. Bosentan therefore causes dilation of the blood vessels and belongs to the class of medications known as "endothelin receptor antagonists".

Bosentan Accordpharma is used to treat:

Bosentan is used to treat patients with pulmonary arterial hypertension (PAH) in class III to improve symptoms and exercise capacity (the ability to perform physical activity). The "class" reflects the severity of the disease: 'class III' implies a marked limitation of physical activity. Some improvements have been observed in patients with PAH class II. The 'class II' implies a slight limitation of physical activity. PAH for which Bosentan is indicated may be:

• primary (in which the cause or hereditary is not identified);
• caused by scleroderma (also known as systemic sclerosis, a disease in which there is abnormal growth of connective tissue that forms the support of the skin and other organs);
• caused by congenital heart defects (at birth) with shunts (abnormal communications) that cause abnormal blood flow between the heart and lungs.

Do not take Bosentan Accordpharma:

• if you are allergic to bosentanor to any of the other ingredients of this medicine (listed in section 6)
• if you have liver problems(ask your doctor)
• if you are pregnant, or could be pregnantas you are not using reliable contraceptive methods. Please read the information in the section “Contraceptives” and “Other medicines and Bosentan Accordpharma”
• if you are taking ciclosporin A(a medicine used after a transplant or to treat psoriasis)

If you have any of these conditions, inform your doctor.

Warnings and precautions

Consult your doctor or pharmacist before taking bosentan.

Tests your doctor will perform before prescribing the treatment

• a blood test to assess liver function
• a blood test to detect if there is anaemia (low haemoglobin)
• a pregnancy test if you are a fertile woman

Abnormalities in liver function tests and anaemia (low haemoglobin) have been found in some patients taking bosentan.

Tests your doctor will perform during the treatment

During treatment with bosentan, your doctor will schedule regular blood tests to monitor changes in your liver function and haemoglobin levels.

Please refer to the Patient Alert Card (inside the bosentan packaging) for these tests. It is essential to perform regular blood tests while taking bosentan. We suggest that you write the date of the most recent test and your next test date (ask your doctor for the date) on the patient alert card to help you remember when your next visit is.

Liver function tests

These tests must be performed monthly throughout the duration of bosentan treatment. After a dose increase, an additional test must be performed after 2 weeks.

Haemoglobin tests

These tests will be performed monthly for the first 4 months of treatment and then every 3 months, as patients taking bosentan may develop anaemia.

If these tests are abnormal, your doctor may decide to reduce the dose or discontinue bosentan treatment and perform additional tests to investigate the cause.

Children and adolescents

Bosentan is not recommended for paediatric patients with systemic sclerosis and active digital ulceration. See also section 3. How to take Bosentan Accordpharma.

Driving and operating machinery

Bosentan has no influence or insignificant influence on driving and operating machinery.

Pregnancy tests

Bosentan may affect unborn babies conceived before or during treatment. If you are a fertile woman, your doctor will ask you to perform a pregnancy test before starting bosentan treatment, and regularly while taking bosentan.

Contraceptives

If you may become pregnant, use a reliable contraceptive method (contraception) while taking bosentan. Your doctor or gynaecologist will advise you on reliable contraceptive methods while taking bosentan. Since bosentan may make hormonal contraception ineffective (e.g. oral, injection, implant, or skin patches), this method alone is not reliable. Therefore, if you use hormonal contraceptives, you must also use a barrier method (e.g. female condom, diaphragm, spermicide, or your partner must also use a condom). Inside the bosentan packaging, you will find a Patient Alert Card that you must read carefully. Your doctor and/or gynaecologist will determine if you need an alternative or additional reliable contraceptive method.
