A

A. Pure alpha adrenergic agonist (E.G. PHENYLEPHRINE, METHOXAMINE) YES, CAN USE TO INCREASE BP

B. Pure beta adrenergic agonist: E.G ISOPROTERENOL, DOBUTAMINE..CAUSE DECREASED BP

C. Pure beta adrenergic antagonist: DECREASE BP

D. Pure cholinergic muscarinic agonist; MUSCARINIC ACTIVATION DECREASES BP

E. Pure cholinergic nicotinic antagonist: HEXAMETHONIUM, MECAMYLAMINE, DECEASE BP, NO LONGER IN USE

This is a good $$$ explanation! leaving out the direct cholinergic agonist to make it a group effort'.

Ach, Bethanocol,Carbochol, Methcholine Pilocarpine, indirect cholinergic agonist are the organophosphates-eg. parathion, malathione.

And the one thats echoed -Beta blockers propanolol and the long acting nadolol
