1. What Bosentan is and what it is used for
Bosentan 62.5 mg or 125 mg Film-coated Tablets contain bosentan and belong to the class of medicines called “endothelin receptor antagonists”.
Bosentan is used to treat:
• Pulmonary arterial hypertension (PAH): PAH is high blood pressure in the blood vessels (the pulmonary arteries) that carry blood form the heart to the lungs. Bosentan widens the pulmonary arteries, making it easier for the heart to pump blood through them. This lowers the blood pressure and relieves the symptoms.
Bosentan is used to treat patients with class III pulmonary arterial hypertension (PAH) to improve exercise capacity (the ability to carry out physical activity) and symptoms. The ‘class’ reflects the seriousness of the disease: ‘class III’ involves marked limitation of physical activity. Some improvements have also been shown in patients with class II PAH. ‘Class II’ involves slight limitation of physical activity. The PAH for which Bosentan is indicated can be:
• primary (with no identified cause or familial);
• caused by scleroderma (also called systemic sclerosis, a disease where there is abnormal growth of the connective tissue that supports the skin and other organs);
• caused by congenital (inborn) heart defects with shunts (abnormal passageways) causing abnormal flow of blood through the heart and lungs.
You must talk to a doctor if you do not feel better or if you feel worse after taking Bosentan.
2. What you need to know before you take Bosentan Do not take Bosentan:
• if you are allergic to bosentan or any of the other ingredients of this medicine (listed in section 6).
• if you have liver problems (ask your doctor).
• if you are taking ciclosporin (a medicine used after a transplant or to treat psoriasis).
• if you are pregnant, or could get pregnant because you are not using reliable contraceptive methods. Please read the information under “Contraceptives” and “Other medicines and
Bosentan”.
Please consult your doctor and do not take Bosentan, if these statements apply to you now or have applied to you at any time in the past.
Warnings and precautions
Tests your doctor will do before you start treatment
• a blood test to check your liver function.
• a blood test to check for anaemia (low haemoglobin).
• a pregnancy test if you are a woman of child-bearing potential.
Some patients taking bosentan have been found to have abnormal liver function tests and anaemia (low haemoglobin) during treatment. Therefore, these conditions should be checked for before starting treatment to reduce the risk that this medicine may make them worse.
Tests your doctor will do during treatment
During treatment with Bosentan, your doctor will arrange for regular blood tests to check for changes in your liver function and haemoglobin level.
For all these tests please refer also to the Patient Reminder Card (inside your pack of Bosentan tablets). It is important that you have these regular blood tests for as long as you are taking Bosentan. We suggest you write the date of your most recent test and also of your next test (ask your doctor for the date) on the patient reminder card, to help you remember when your next test is due.
Blood tests for liver function
These will be done every month for the duration of treatment with Bosentan. After an increase in dose an additional test will be done after 2 weeks.
Blood tests for anaemia
These will be done every month for the first 4 months of treatment, then every 3 months after that, as patients taking Bosentan may get anaemia.
If these results are abnormal, your doctor may decide to reduce your dose or stop treatment with Bosentan and to perform further tests to investigate the cause.
Children and adolescents
There is only limited clinical experience in children with pulmonary arterial hypertension under 2 years of age. Bosentan is not recommended in paediatric patients with systemic sclerosis and ongoing digital ulcer disease. Please see also section 3. How to take Bosentan .
Other medicines and Bosentan
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. It is especially important to tell your doctor if you are taking:
• hormonal contraceptives (as these are not effective as the sole method of contraception when you take Bosentan). Inside your pack of Bosentan tablets you will find a patient
reminder card which you should read carefully. Your doctor and/or gynaecologist will establish the contraception which is appropriate for you.
• glibenclamide (for diabetes - as this combination may increase the risk of side effects).
• ciclosporin (a medicine used after transplants and to treat psoriasis, see section “Do not take Bosentan”), tacrolimus, sirolimus or any other medicines used to prevent rejection of transplanted organs - as these medicines may increase the concentrations of Bosentan in your blood.
• fluconazole, ketoconazole, itraconazole, voriconazole (to treat fungal infections - as these medicines may increase the concentrations of Bosentan in your blood).
• simvastatin (used to lower cholesterol levels) or warfarin (used to prevent blood clotting) - as Bosentan may reduce the concentrations of these medicines in your blood.
• sildenafil (used to treat erectile dysfunction) - as Bosentan may reduce the concentration of this medicine in your blood.
• rifampicin (to treat tuberculosis - as this medicine may reduce the efficacy of Bosentan).
• carbamazepine, phenobarbital, phenytoin (medicines normally used for the treatment of epilepsy) or St. John’s wort (used to treat depression) - as these medicines may reduce the efficacy of Bosentan.
• ritonavir and lopinavir, nevirapine, or other medicines for the treatment of HIV infection.
Pregnancy, breast-feeding and fertility Women of child-bearing age
Do NOT take Bosentan if you are pregnant or planning to have a baby.
Pregnancy tests
Bosentan may harm unborn babies conceived before starting or during treatment. If you are a woman who could become pregnant, your doctor will ask you to take a pregnancy test before you start taking Bosentan, and then every month while you are taking Bosentan.
Contraceptives
If it is possible that you could become pregnant, use a reliable form of birth control (contraception) while you are taking Bosentan. Your doctor or gynaecologist will advise you about reliable contraceptive methods while taking Bosentan. Because Bosentan may make hormonal contraception (e.g., tablets, injection, implant, or skin patches) ineffective, this method on its own 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 your pack of Bosentan tablets you will find a Patient Reminder Card. You should complete this card and take it to your doctor at your next visit so that your doctor or gynaecologist can assess whether you need additional or alternative reliable contraceptive methods. Monthly pregnancy tests are recommended while you are taking Bosentan and are of child-bearing age.
Tell your doctor immediately if you become pregnant while you are taking Bosentan, or plan to become pregnant in the near future.
Breast-feeding
Tell your doctor immediately if you are breast-feeding. You are advised to stop breast-feeding if Bosentan is prescribed for you, because it is not known whether this medicine passes into breast milk.
Fertility
Fertility studies in animals showed no effects on sperm parameters or fertility.
Driving and using machines
Bosentan has no or negligible influence on the ability to drive and use machines. However, Bosentan can induce hypotension (decrease of your blood pressure) which can make you feel faint or dizzy and affect your ability to drive and use machines. Therefore, if you feel dizzy while taking Bosentan, do not drive or operate any tools or machines.
3. How to take Bosentan
Treatment with Bosentan should only be started and monitored by a doctor who has experience in the treatment of PAH. Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
If you have the impression that the effect of Bosentan is too strong or too weak, talk to your doctor in order to find out whether your dose needs to be changed.
Recommended dose
Adults
The treatment in adults is usually started for the first 4 weeks with the recommended dose of 62.5 mg twice daily (morning and evening) From then your doctor will usually advise you to take a 125 mg tablet twice daily, depending on how you react to Bosentan.
Use in Children and adolescents aged 2 years and over
The dose recommendation in children is only for the treatment of pulmonary arterial hypertension. For children 2 years and older, the recommended dose for treatment with Bosentan is usually started with 2 mg per kg of body weight twice daily (morning and evening). Your doctor will advise you on the exact amount to give to your child.
How to take Bosentan
Tablets should be taken (morning and evening), swallowed with water. The tablets can be taken with or without food.
If you take more Bosentan than you should
If you take more tablets than you have been told to take, contact your doctor at once.
You may get symptoms such as headache, feeling or being sick, low blood pressure (which may make you feel faint or dizzy), sweating and blurred vision.
If you forget to take Bosentan
If you forget to take Bosentan, take a dose as soon as you remember, then continue to take your tablets at the usual times. Do not take a double dose to make up for forgotten tablets.
If you stop taking Bosentan
Suddenly stopping your treatment with Bosentan may lead to your symptoms getting worse. Do not stop taking Bosentan unless your doctor tells you to. Your doctor may tell you to reduce the dose over a few days before stopping completely.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
