Metaraminol Mechanism Of Action. Metaraminol acts on both α1-adrenergic receptors but appears to have no effect on β-adrenergic receptors. The mechanism responsible for the analgesic effect is a complex one and most probably rests on the inhibition of a central cyclooxygenase-3 and activation of the opioidergic system and cannabinoid system. It is less likely to cause a reflex bradycardia than methoxamine or phenylephrine. 2 Other alpha-adrenoceptor blocking drugs phenoxybenzamine phentolamine did not significantly lower heart amine c.

Metaraminol The catecholamines have variable vasopressor activity and are not usually considered here Catecholamines consist of an aromatic ring attached to a terminal amine by a carbon chain. This results in an increase in peripheral resistance and elevation of blood pressure. Indirect increase in coronary artery flow. It increases haemodynamic stability during surgery at recovery from anaesthesia and may reduce cardiac morbidity in high-risk cases. When given orally or iv results in dose dependent sedation reduces the dose of induction drug needed reduces the MAC of volatile anaesthetics and provides a degree of analgesia. Metaraminol is a potent sympathomimetic amine that increases both systolic and diastolic blood pressure.
Direct and indirect via noradrenaline release alpha 1 receptor agonist.
Metaraminol is a vasoconstrictor that predominantly stimulates α 1 receptors to cause peripheral vasoconstriction and increase blood pressure. This results in an increase in peripheral resistance and elevation of blood pressure. The pressor effect begins one to two minutes after intravenous injection about 10 minutes after intramuscular injection 5 to 20 minutes after subcutaneous injection and lasts about 20 minutes to one hour. Metaraminol is a potent sympathomimetic amine that increases both systolic and diastolic blood pressure. Increases SVRPVR increases BP. The congura-tion of each drug is important for determining anity to respective receptors.
