4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Neuromuscular Nondepolarizing Agents

Drugs that interrupt transmission at the skeletal neuromuscular junction without causing depolarization of the motor end plate. They prevent acetylcholine from triggering muscle contraction and are used as muscle relaxants during electroshock treatments, in convulsive states, and as anesthesia adjuvants. (See all compounds classified as Neuromuscular Nondepolarizing Agents.)


Nicotinic Antagonists

Drugs that bind to nicotinic cholinergic receptors (RECEPTORS, NICOTINIC) and block the actions of acetylcholine or cholinergic agonists. Nicotinic antagonists block synaptic transmission at autonomic ganglia, the skeletal neuromuscular junction, and at central nervous system nicotinic synapses. (See all compounds classified as Nicotinic Antagonists.)
