Byscard Tab is an effective medication for hypertension, or high blood pressure. If left untreated, the condition can be harmful and lead to various health problems including cardiac arrest, kidney issues and stroke. The medication contains a beta-blocker known as nebivolol as an active component. Nebivolol relaxes blood vessels and allows the blood to circulate more easily throughout the body. This lowers the strain on the heart, making it easier for it to pump blood, and so lowers blood pressure. The medicine helps with various health conditions caused due to high blood pressure. The medication is especially helpful for people who have a family history of hypertension or other risk factors for heart disease or stroke.
