The name of your medicine is Bopaho 62.5 mg film-coated tablets or Bopaho 125 mg film-coated tablets (called Bopaho throughout this leaflet).
Bopaho tablets contain bosentan, which blocks a naturally occurring hormone called endothelin-1 (ET-1), which causes blood vessels to narrow. Bopaho therefore causes blood vessels to expand and belongs to the class of medicines called “endothelin receptor antagonists”.
Bopaho is used to treat:
- Pulmonary arterial hypertension (PAH): PAH is a disease of severe narrowing of the blood vessels in the lungs resulting in high blood pressure in the blood vessels (the pulmonary arteries) that carry blood from the heart to the lungs. This pressure reduces the amount of oxygen that can get into the blood in the lungs, making physical activity more difficult. Bopaho widens the pulmonary arteries, making it easier for the heart to pump blood through them. This lowers the blood pressure and relieves the symptoms.
Bopaho 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 Bopaho 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.
• 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 pregnant, or could get pregnant because you are not using reliable contraceptive methods. Please read the information under "Contraceptives" and "Other medicines and Bopaho").
• if you are taking cyclosporin A (a medicine used after a transplant or to treat psoriasis).
If any of these apply to you, tell your doctor.
Tests your doctor will do before 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 Bopaho have been found to have abnormal liver function tests and anaemia (low haemoglobin).
During treatment with Bopaho, 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 Alert Card (inside your pack of Bopaho tablets). It is important that you have these regular blood tests as long as you are taking Bopaho. 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 Alert Card, to help you remember when your next test is due.
These will be done every month for the duration of treatment with Bopaho. After an increase in dose an additional test will be done after 2 weeks.
These will be done every month for the first 4 months of treatment, then every 3 months after that, as patients taking Bopaho may get anaemia.
If these results are abnormal, your doctor may decide to reduce your dose or stop treatment with Bopaho and to perform further tests to investigate the cause.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription. It is especially important to tell your doctor if you are taking:
- Cyclosporin A (a medicine used after transplants and to treat psoriasis), which must not be used together with Bopaho
- Sirolimus or tacrolimus, which are medicines used after transplants, as these are not recommended to be used together with Bopaho
- Glibenclamide (a diabetes medicine), rifampicin (a tuberculosis medicine), fluconazole or ketoconazole (medicines against fungal infections), nevirapine (an HIV medicine) as these medicines are not recommended to be used together with Bopaho
- Other medicines for the treatment of HIV infection such as lopinavir and ritonavir, which may require special monitoring if used together with Bopaho
- Hormonal contraceptives, which are not effective as the sole method of contraception when you take Bopaho. Inside your pack of Bopaho tablets you will find a Patient Alert Card which you should read carefully. Your doctor and/or gynaecologist will establish the contraception which is appropriate for you
- Warfarin (a medicine used to prevent blood clotting), which requires more frequent monitoring if used together with Bopaho
- Sildenafil (a medicine used to treat erectile dysfunction and pulmonary arterial hypertension), which requires caution when used with Bopaho
- Simvastatin (a medicine used to decrease elevated lipid levels in blood), which may require monitoring of cholesterol levels and a dose adjustment if it’s necessary.
Bopaho has no or negligible influence on the ability to drive and use machines. However, Bopaho can induce hypotension (decrease of your blood pressure) which can make you feel dizzy and affect your ability to drive and use machines. Therefore, if you feel dizzy while taking Bopaho, do not drive or operate any tools or machines.
Bopaho can be taken with or without food.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking Bopaho.
Do NOT take Bopaho if you are pregnant or planning to become pregnant.
Bopaho 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 Bopaho, and regularly while you are taking Bopaho.
If it is possible that you could become pregnant, use a reliable form of birth control (contraception) while you are taking Bopaho. Your doctor or gynaecologist will advise you about reliable contraceptive methods while taking Bopaho. Because Bopaho may make hormonal contraception (e.g., oral, 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 Bopaho tablets you will find a Patient Alert 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 Bopaho and are of child-bearing age.
Tell your doctor immediately if you become pregnant while you are taking Bopaho, or plan to become pregnant in the near future.
Tell your doctor immediately if you are breast-feeding. You are advised to stop breastfeeding if Bopaho is prescribed for you, because it is not known whether this medicine passes into breast milk.
If you are a man taking Bopaho, it is possible that this medicine may lower your sperm count. It cannot be excluded that this may affect your ability to father a child. Talk to your doctor if you have any questions or concerns about this.
Treatment with Bopaho 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 has told you.
Check with your doctor or pharmacist if you are not sure.
The treatment in adults is usually started for the first 4 weeks with 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 Bopaho.
Children and adolescents
The dose recommendation in children is only for PAH. For children 1 year and older, treatment with Bopaho is usually started with 2 mg per kg bodyweight twice daily (morning and evening). Your doctor will advise you on your dosing.
Bopaho should not be administered to children with a body weight below 31 kg, and an alternative product containing bosentan should be used.
If you have the impression that the effect of Bopaho is too strong or too weak, talk to your doctor in order to find out whether your dose needs to be changed.
Tablets should be taken (morning and evening), swallowed with water. The tablets can be taken with or without food.
If you take more tablets than you have been told to take, contact your doctor immediately.
If you forget to take Bopaho, 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.
Suddenly stopping your treatment with Bopaho may lead to your symptoms getting worse. Do not stop taking Bopaho 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
