Description

Metocurine, also known as dimethyltubocurarine, is a non-depolarizing muscle relaxant through the neuromuscular blockade. It antagonizes the neurotransmitter action of acetylcholine by binding competitively with cholinergic receptor sites on the motor end-plate. Patients chronically receiving anticonvulsants are relatively resistant to metocurine.

skeletal muscle relaxation 7 Sources: https://www.drugbank.ca/drugs/DB00416	Primary		Approved 8583	METOCURINE IODIDE Approved Use Metocurine iodide is a benzylisoquinolinium competitive nondepolarizing neuromuscular blocking agent. It is used as an anesthesia adjunct to induce skeletal muscle relaxation and to reduce the intensity of muscle contractions in convulsive therapy Metocurine iodide has a moderate risk of inducing histamine release and has some ganglion blocking activity. Metocurine iodide can be used most advantageously if muscle twitch response to peripheral nerve stimulation is monitored to assess degree of muscle relaxation. Metocurine Iodide is no longer available on the US market.
