Generic Name: nadolol and bendroflumethiazide (Oral route)
Following abrupt cessation of therapy with certain beta-blocking agents, exacerbations of angina pectoris and, in some cases, myocardial infarction have occurred. The dosage should be gradually reduced over 1 to 2 weeks and the patient should be carefully monitored when discontinuing chronic therapy, particularly in patients with ischemic heart disease. If angina markedly worsens or acute coronary insufficiency develops, nadolol should be reinstated promptly, at least temporarily, and other measures appropriate for the management of unstable angina should be taken. Patients should be warned against interruption or discontinuation of therapy without the physician's advice .

Uses For Corzide
Nadolol and bendroflumethiazide combination is used to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled .
Nadolol is a beta-blocker. It works by affecting the response to some nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart .
Bendroflumethiazide is a diuretic (water pill). It reduces the amount of water in the body by increasing the flow of urine, which helps lower the blood pressure .
This medicine is available only with your doctor's prescription .
