Application

Mecamylamine hydrochloride has been used as an additive in extracellular saline during current-clamp recordings to reduce synaptic input. It has also been used as a non-selective nicotinic acetyl choline receptor blocker in aortic body neurons and in MLO-Y4 cells.

Biochem/physiol Actions

Noncompetitive nicotinic acetylcholine receptor antagonist; preferentially blocks nicotinic receptors at autonomic ganglia; crosses blood-brain barrier.

Pharmacological mechanisms involved in nicotine-induced seizures were investigated in mice by testing the ability of several nicotinic agonists in producing seizures after peripheral administration. In addition, nicotinic antagonists such as hexamethonium, mecamylamine, dihydro-beta-erythroidine, and methyllycaconitine citrate (MLA) were used in

Mating and egg laying are tightly cooordinated events in the reproductive life of all oviparous females. Oviposition is typically rare in virgin females but is initiated after copulation. Here we identify the neural circuitry that links egg laying to mating status
