Dimethyl Tubocurarine Iodide
Dimethyl Tubocurarine Iodide Uses, Dosage, Side Effects, Food Interaction and all others data.
Dimethyl Tubocurarine 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 Dimethyl Tubocurarine Iodide has a moderate risk of inducing histamine release and has some ganglion blocking activity. Dimethyl Tubocurarine 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.
Dimethyl Tubocurarine Iodide is a benzylisoquinolinium competitive nondepolarizing neuromuscular blocking agent. Dimethyl Tubocurarine Iodide has a moderate risk of inducing histamine release and has some ganglion blocking activity. Dimethyl Tubocurarine Iodide can be used most advantageously if muscle twitch response to peripheral nerve stimulation is monitored to assess degree of muscle relaxation. As with other nondepolarizing neuromuscular blockers, the time to onset of paralysis decreases and the duration of maximum effect increases with increasing doses of metocurine iodide. Repeated administration of maintenance doses of metocurine iodide has no cumulative effect on the duration of neuromuscular block if recovery is allowed to begin prior to repeat dosing. Moreover, the time needed to recover from repeat doses does not change with additional doses. Repeat doses can therefore be administered at relatively regular intervals with predictable results.

Uses
For use as an anesthesia adjunct to induce skeletal muscle relaxation and to reduce the intensity of muscle contractions in convulsive therapy.
How Dimethyl Tubocurarine Iodide works
Dimethyl Tubocurarine Iodide antagonizes the neurotransmitter action of acetylcholine by binding competitively with cholinergic receptor sites on the motor end-plate. This antagonism is inhibited, and neuromuscular block reversed, by acetylcholinesterase inhibitors such as neostigmine, edrophonium, and pyridostigmine.
Toxicity
Excessive doses can be expected to produce enhanced pharmacological effects. Overdosage may increase the risk of histamine release and cardiovascular effects, especially hypotension.
Half Life
3 to 4 hours
