RIOTEPH 0.5MG contain Riociguat which belongs to a group of medicine called soluble guanylate cyclase (sGC) stimulator. It is used to treat adults with certain forms of pulmonary hypertension such as chronic thromboembolic pulmonary hypertension (CTEPH) and certain types of pulmonary arterial hypertension (PAH).
Pulmonary hypertension is a condition in which these blood vessels become narrowed, making it harder for the heart to pump blood through them and leading to high blood pressure in the vessels. Because the heart must work harder than normal, people with pulmonary hypertension feel tiredness, dizziness and short of breath. By widening the narrowed arteries, this medicine leads to an improvement in your ability to carry out physical activity.
In chronic thromboembolic pulmonary hypertension (CTEPH), the blood vessels of the lung are blocked or narrowed with blood clots. This medicine can be used for patients with CTEPH who cannot be operated on, or after surgery for patients in whom increased blood pressure in the lungs remains or returns.
In pulmonary arterial hypertension (PAH), the wall of the blood vessels of the lungs are thickened and the vessels become narrowed. This medicine is only prescribed for certain forms of PAH, i.e. idiopathic PAH (the cause of PAH is unknown), heritable PAH and PAH caused by connective tissue disease. Your doctor will check this. This medicine can be taken alone or together with certain other medicines used to treat PAH.
This medicine is strictly not recommended for use in children and adolescents under 18 years. Before taking this medicine tell your doctor if you have ever had kidney disease, heart disease, liver problems. Pregnant and breastfeeding women should consult their doctor before taking this medicine.
