Doxacard 4 mg Tablet belongs to a class of drugs called alpha-blockers used to treat hypertension (high blood pressure) and symptoms of benign prostatic hyperplasia (enlarged prostate). Hypertension is a condition in which the force exerted by the blood against the artery walls becomes so high that it causes health problems, such as heart disease. Benign prostatic hyperplasia is a condition in men that causes enlargement of the prostate gland.

Doxacard 4 mg Tablet contains Doxazosin which works by blocking alpha receptors on the muscle in the walls of the blood vessel. Thereby, it relaxes and widens blood vessels so that blood passes through them more easily. This helps to lower blood pressure.

Hypertension: Blood pressure is the measurement of the heart's force to pump blood to all parts of the body. Hypertension (high blood pressure) is a chronic condition in which blood pressure is too high. 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 (when the blood supply to the heart is blocked). Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. High blood pressure can be diagnosed with the help of a blood pressure monitor or sphygmomanometer. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is the pressure when your heart is at the resting stage between heartbeats. If your blood pressure is 140/90 mm of Hg, it means the systolic pressure is 140 mm of Hg, and diastolic pressure is 90 mm of Hg. Normal blood pressure lies between 90/60 mm of Hg and 120/80 mm of Hg. If the blood pressure is 140/90 mmHg or greater, it is considered high blood pressure.
