Opsutan Tablet 10's belongs to the class of 'anti-hypertensive drugs', primarily used to treat high blood pressure in the lungs' arteries (pulmonary arterial hypertension). Hypertension is a medical condition in which the blood exerts high pressure (force exerted by circulating blood) against the walls of blood vessels. This condition makes the heart work harder in pumping blood to the whole body. Pulmonary hypertension affects arteries in the lungs and the right side of the heart.

Opsutan Tablet 10's contains 'macitentan', which works by inhibiting the action of Endothelin, a natural substance that constricts blood vessels and raises blood pressure. Opsutan Tablet 10's widens the constricted pulmonary arteries (blood vessels that carry blood from the heart to the lungs) and increases blood supply, thus lowering blood pressure.

Opsutan Tablet 10's is an anti-hypertensive medicine that treats high blood pressure in the lungs' arteries (pulmonary arterial hypertension (PAH)). It contains 'Macitentan,' which works by inhibiting the action of Endothelin, a natural substance that constricts blood vessels and raises blood pressure. In people with PAH, the pulmonary arteries get narrower making the heart work harder to pump blood through them. Opsutan Tablet 10's widens these constricted arteries and makes it easier for the heart to pump blood, thus lowering the blood pressure.

Pulmonary Arterial Hypertension: It is referred to as high blood pressure in the blood vessels (the pulmonary arteries) that carry blood from the heart to the lungs. It's a serious condition that can harm the heart's right side. The walls of the pulmonary arteries thicken and stiffen, making it difficult for blood to flow through. Because of the reduced blood flow, the right side of the heart has a harder time pumping blood through the arteries which may lead to heart failure. The common symptoms of pulmonary hypertension are shortness of breath, dizziness, palpitations, and chest pressure. It can affect people of all ages, but it is more common in people who already have a heart or lung problem.
