Metaraminol is a selective α₁-adrenergic receptor agonist with vasoconstrictive properties. It primarily increases blood pressure by inducing peripheral vasoconstriction, making it useful in treating hypotension during anesthesia or shock. Additionally, metaraminol has some indirect sympathomimetic activity by stimulating norepinephrine release, further enhancing its pressor effects. Unlike direct-acting catecholamines, it has a longer duration of action due to slower metabolism.
