6. Contents of the package and additional information

Bosentan Kern Pharma contains bosentan, which blocks the natural hormone called endothelin-1 (ET-1), and causes narrowing of blood vessels. Bosentan therefore causes dilation of blood vessels. It belongs to the class of medications called “endothelin receptor antagonists”.

Bosentan is used to treat:

• Pulmonary arterial hypertension(PAH): PAH is a severe narrowing of the blood vessels in the lungs resulting in 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 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.

The PAH for which bosentan is indicated may be:

• primary (in which the cause or hereditary is not identified);
• caused by systemic sclerosis (also called scleroderma, 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 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 systemic sclerosis. Bosentan reduces the number of new digital ulcers (on hands and feet) that appear.

Warnings and Precautions

Tests your doctor will perform before prescribing the treatment

• a blood test to evaluate liver function
• a blood test to detect anemia (low hemoglobin)
• a pregnancy test if you are a fertile woman

Abnormalities in liver function tests and anemia 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 hemoglobin 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 this medication. We recommend 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 should be performed monthly throughout the duration of bosentan treatment. After a dose increase, an additional test should be performed 2 weeks later.

Anemia 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 anemia.

If these tests show abnormalities, 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 pediatric patients with systemic sclerosis and active digital ulceration. See also section 3. How to Take Bosentan Kern Pharma.

Other Medications and Bosentan Kern Pharma

If you may become pregnant, use a reliable contraceptive method (contraception) while taking bosentan.

Inside the packaging of this medication, you will find a Patient Alert Card that you should read carefully. Your doctor and/or gynecologist will determine if you need an alternative or additional reliable contraceptive method.
