Calan contains Verapamil, used alone or in combination with other drugs to treat arrhythmias, angina or hypertension.
High blood pressure increases the work load on the heart and arteries, so if blood pressure is high for a long time, it will lead to the heart and arteries not working properly. The result is damage to the blood vessels of the brain, heart, and kidneys, leading to complications such as stroke, heart failure, or kidney failure. In addition, high blood pressure can also increase the risk of a heart attack. All of the above problems can be limited if blood pressure is effectively controlled.
Verapamil in Calan is an active calcium channel blocker. Calan affects the movement of calcium ions into the cells of the heart and vascular smooth muscle. The result is dilation of blood vessels, stimulating heart muscle contractions to increase blood and oxygen supply to the heart while reducing the organ's workload.
