The direct-acting ch Direct-acting cholinomimetics are drugs that act directly by stimulating cholinergic receptors. Cholinomimetics are also classified by their mechanism of action because some bind directly to (and activate) cholinoceptors whereas others act indirectly by inhibiting the hydrolysis of endogenous acetylcholine. That's because unlike acetylcholine, direct cholinomimetics don't bind to the muscarinic and nicotinic receptors equally.
