1. What is Bosentan Accordpharma and what is it used for

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

Bosentan Accordpharma is used to treat:

• Pulmonary Arterial Hypertension (PAH): PAH is a disease of severe narrowing of the blood vessels in the lungs, leading to an increase in blood pressure in the blood vessels (pulmonary arteries) that carry blood from the heart to the lungs. This pressure reduces the amount of oxygen that can reach the blood in the lungs, making physical activity more difficult. Bosentan widens the pulmonary arteries, making it easier for the heart to pump blood through them. This reduces blood pressure and alleviates symptoms.

Bosentan is used for the treatment of 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 marked limitation of physical activity. Some improvements have been observed in patients with PAH class II. The 'class II' implies slight limitation of physical activity. The PAH for which Bosentan is indicated may be:

• Primary (in which no cause is identified or hereditary);
• Caused by scleroderma (also called 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 (present at birth) with shunts (abnormal communications) that cause abnormal blood flow between the heart and lungs.

• Digital ulcers (ulcers on the fingers of the hands and feet) in adult patients suffering from a disease called scleroderma. Bosentan reduces the number of new digital ulcers (on hands and feet) that appear.

2. What you need to know before you take Bosentan Accordpharma

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 pregnantby not using reliable contraceptive methods. Please read the information in the section "Contraceptives" and "Other medicines and Bosentan Accordpharma"
• If you are taking cyclosporine A(a medicine used after transplants 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 that your doctor will perform before prescribing treatment

• a blood test to assess liver function
• a blood test to detect if you have anemia (low hemoglobin)
• a pregnancy test if you are a woman of childbearing age

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

Blood tests that your doctor will perform during treatment

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

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

Liver function blood tests

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

Anemia blood tests

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

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

Children and adolescents

Bosentan is not recommended in pediatric patients with systemic sclerosis with active digital ulcers. See also section 3. How to take Bosentan Accordpharma.

Other medicines and Bosentan Accordpharma

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines, including those obtained without a prescription. It is especially important that you inform your doctor if you are taking:

• cyclosporine A (a medicine used after transplants or to treat psoriasis) which must not be taken with bosentan.
• sirolimus or tacrolimus, which are medicines used after transplants, and are not recommended to be taken with bosentan.
• glibenclamide (a medicine for diabetes), rifampicin (a medicine for tuberculosis), fluconazole (medicines against fungal infections), ketoconazole (a medicine used to treat Cushing's syndrome), or nevirapine (a medicine for HIV) which are not recommended to be taken with bosentan.
• other medicines for the treatment of HIV infection, which, when taken with bosentan, may require special monitoring.
• oral contraceptives, which are not effective as the only contraceptive method when taking bosentan. Inside the box of Bosentan Accordpharma, you will find a Patient Alert Card that you must read carefully. Your doctor and/or gynecologist will determine the appropriate contraceptive method for you.
• other medicines for the treatment of pulmonary hypertension: sildenafil and tadalafil:
• warfarin (an anticoagulant agent);
• simvastatin (used to treat hypercholesterolemia).

Driving and using machines

Bosentan has no influence or negligible influence on the ability to drive and use machines. However, bosentan may cause hypotension (low blood pressure) that can cause dizziness, affect your vision, and affect your ability to drive and use machines. Therefore, if you feel dizzy or have blurred vision while taking bosentan, do not drive or operate tools or machinery.

Women of childbearing age

DO NOT take bosentan if you are pregnant or plan to become pregnant.

Pregnancy tests

Bosentan may affect unborn children conceived before or during treatment. If you are a woman of childbearing age, your doctor will ask you to have a pregnancy test before starting treatment with bosentan and regularly while taking bosentan.

Contraceptives

If you may become pregnant, use a reliable contraceptive method (contraception) while taking bosentan. Your doctor or gynecologist will advise you on reliable contraceptive methods while taking bosentan. Since bosentan can make hormonal contraception not effective (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, contraceptive sponge, or your partner must also use a condom). Inside the box of bosentan tablets, you will find the patient alert card. You must complete this card and bring it to your doctor at your next visit so that your doctor or gynecologist can determine if you need an alternative or additional reliable contraceptive method. It is recommended to have a monthly pregnancy test while taking bosentan and being of childbearing age.

Tell your doctor immediately if you become pregnant while taking bosentan or plan to become pregnant in the near future.

Breast-feeding

Bosentan passes into breast milk.You are advised to interrupt breast-feeding if you are prescribed bosentan because it is unknown whether the presence of bosentan in breast milk can harm your baby.

Tell your doctorimmediately if you are breast-feeding.
