ActionDrugExtra Info
α-1 and non-selective beta antagonist3rd gen, used in heart failure
α-2 antagonist
non-selective α-antagonistcauses reflex tachycardia and postural hypotension
α-2 antagonistprodrug for alpha-methylNA, centrally acting antihypertensive
β-1 antagonistused in hypertension, cardiac dysrhytmia and angina
adrenoreceptor agonistproduced in the adrenal gland from tyrosine
non-selective β-agonisthas an antagonistic isomer
non-selective β-antagonistno longer used in hypertension due to bronchoconstriction
α-2 antagonist
α-2 agonistslightly selective, centrally-acting antihypertensive (hindbrain), omitting a single dose leads to rebound hypertension
β blockerclass II and III antidysrhythmic action
α and β antagonistused to treat hypertension in pregnancy, four isomers, 3rd gen.
β-2 agonistused in asthma to relax bronchi
