Indication of Tensig:
HypertensionAnginaTachyarrhythmiasMyocardial infarctionPrevention of migraine
Action of Tensig:
Atenolol, a type of beta-1-selective-beta-Blocker, competitively blocks beta- adrenoceptors in the heart, peripheral vasculature, bronchi, pancreas, uterus, kidney, brain and liver.The antihypertensive effect works by reducing cardiac output without reflex increase in peripheral vascular resistance; CNS effect and reduced renin secretionmay also contribute.The antianginal effect is due to reductionin left ventricular work and oxygen use, resulting from decrease in heart rate and contractility.The antiarrhythmic properties are due to antisympathetic effects: depression ofsinus node function and atrio-ventricular conduction and prolongation of atrial refractory periods.Atenolol, a beta-1-selective blocker, has a higher affinity for beta-1 receptors in the heart with less effect on beta-2 receptorsin bronchi and peripheral vasculature
