Curare poisoning can be indicated by typical signs of neuromuscular-blocking drugs such as paralysis including respiration but not directly affecting the heart. Curare poisoning can be managed by artificial respiration such as mouth-to-mouth resuscitation. In a study of 29 army volunteers that were paralyzed with curare, artificial respiration managed to keep an oxygen saturation of always above 85%, a level at which there is no evidence of altered … WebMechanism of Toxicity d -Tubocurarine acts as a non-depolarizing competitive antagonist at nicotinic acetylcholine receptors on the motor end plate of the neuromuscular junction, causing the relaxation of skeletal muscle. d -Tubocurarine competes with at least an equal affinity to acetylcholine, and at the same position on nicotinic receptors.
