Cephalalgia 16 (1996): 328-36.Propranolol belongs to a group of drugs called beta blockers.Mechanism of antimigraine action unknown but thought to be related to inhibition of cerebral vasodilation and propranolol mechanism of action migraine arteriolar spasms.Propranolol 40 mg daily titrating up to a maximum of 160 mg,-vertigo decreased 12.Propranolol is a beta-adrenergic receptor antagonist used to treat hypertension 8,9.The objectives of the present study were to investigate these drugs’ effects on arterial wall dynamics and the potential relation between their vascular and clinical effect Propranolol is not only a psychotropic drug.The mechanism of the antihypertensive effect of propranolol has not been established.Migraine headache prophylaxis: Prophylaxis of common migraine headache The possible mechanisms of action of propranolol in the prophylactic treatment of migraine are listed below: Blockade of these beta adrenergic receptors results in inhibition of arterial dilatation.4 Propranolol is a beta-adrenergic blocking agent that is used for treating high blood pressure, heart pain (), abnormal rhythms of the heart, and some neurologic conditions.Beta blockers reduce the frequency of migraine attacks in 60 to 80 percent of people.However, the authors speculate on possible modes of action in view the current understanding of the properties of propranolol.They reduce portal pressure by producing splanchnic vasoconstriction, thereby reducing portal blood flow..Mechanism of Action: β-1 receptor blockers without intrinsic sympathomimetic activity have been shown to decrease the frequency & severity of attacks.It is a nonselective antagonist of beta receptors (blocks both β1 and β2 receptors equally).7,8,9 When patients abruptly stop taking propranolol, they may experience exacerbations of angina and myocardial infarctions.When access to β-receptor sites is blocked by Propranolol HCl, the chronotropic, inotropic, and vasodilator responses to beta-adrenergic stimulation are decreased.
