Isdil-90 SR Tablet is used to treat mild to moderate hypertension (high blood pressure). It is also indicated in the management of chronic stable angina and angina due to coronary artery spasms. High blood pressure is a condition in which the blood exerts increased pressure on the walls of blood vessels, leading to hypertension. Angina or chest pain occurs due to reduced blood flow to the heart, which is caused by narrowing or blockage of the heart's arteries (coronary artery).

Isdil-90 SR Tablet contains 'Diltiazem', which works by relaxing the blood vessels in the heart and thereby reducing the raised blood pressure. Isdil-90 SR Tablet  eases anginal chest pain by preventing the narrowing of blood vessels and dilating the coronary arteries. As a result, Isdil-90 SR Tablet helps treat/prevent high blood pressure and angina.

Isdil-90 SR Tablet belongs to the group of anti-hypertensive medicines called calcium channel blockers used to treat mild to moderate hypertension (high blood pressure). It is also indicated in the management of chronic stable angina and angina due to coronary artery spasms. Isdil-90 SR Tablet works by inhibiting the movement of calcium ions across the heart muscle and smooth muscle linings of the blood vessels, thereby relaxing and widening the narrowed blood vessels, making it easier for the blood and oxygen to reach the heart. This, in turn, helps in lowering the blood pressure and the risk of having a heart attack or stroke. Isdil-90 SR Tablet  eases anginal chest pain by preventing the narrowing of blood vessels and dilating the coronary arteries.

High blood pressure (hypertension): It is a condition in which the blood exerts increased pressure on the walls of blood vessels, leading to hypertension. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Raised blood pressure can cause chest pain (angina) and heart attack. Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. Symptoms of high blood pressure include headache, dizziness, nose bleed, changes in vision, chest pain, weakness and dyspnoea (shortness of breath). However, most of the time, the signs and symptoms of hypertension are none.

Angina (chest pain): It occurs due to reduced blood flow to the heart, which is caused by narrowing or blockage of the heart's arteries (coronary artery). The blockade usually occurs due to the build-up of fat/cholesterol in the coronary artery. Symptoms include pain or tightness in the chest, neck, arms or back, weakness, lightheadedness, anxiety and abnormal heartbeat.
