Tenormin is a popular and effective medication that has been used in the treatment of high blood pressure. It is composed of active component Atenolol. This medicine has been manufactured by the leading pharmaceutical company, Mylan Pharma. It is composed of a conventional tablet form in dosages 25 mg, 50 mg, and 100 mg.
Manufacturer: Mylan Pharma
Active Ingredient: The active ingredient used in this medicine is Atenolol. This active component is a synthetic isopropylamino-propanol derivative used as an antihypertensive, hypotensive and antiarrhythmic. It acts as a peripheral, cardioselective beta blocker specific for beta-1 adrenergic receptors, without intrinsic sympathomimetic effects. It reduces exercise heart rates and delays atrioventricular conduction, with overall oxygen requirements decreasing. This ingredient is a so-called beta1-selective drug. That means that it exerts greater blocking activity on myocardial beta1-receptors than on beta2 ones in the lung. The beta2 receptors are responsible to keep the bronchial system open.
Indications: Atenolol composed medicine Tenormin is used with or without other medications to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This medication is also used to treat chest pain and to improve survival after a heart attack.
It is a beta-blocker that blocks the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart.
Action Mechanism: The important function of beta-adrenergic nerves is to stimulate the heart muscle to beat more rapidly. This medicine Tenormin works by blocking the stimulation by these nerves, atenolol reduces the heart rate and is useful in treating abnormally rapid heart rhythms. It also reduces the force of contraction of heart muscle and lowers blood pressure. By reducing the heart rate, the force of muscle contraction, and the blood pressure against which the heart must pump, it reduces the work of heart muscle and the need of the muscle for oxygen.
