3140 Alcuronium Alcuronium is a type of curare, a plant toxin known for its use as paralyzing arrow poison by South American indigenous people. It can be extracted from a variety of plants, including Strychnos toxifera and Chondrodendron tomentosum. Curares are active only by an injection. They are harmless if taken orally because curare compounds are too large and too highly charged to pass through the lining of the digestive tract to be absorbed into the blood. (L1256) 23214-96-2 5360723 C44H50Br2N4O2 666.8934 White powder. Injection (sting/bite) (L1256) Curare is a non-depolarizing muscle relaxant that acts as a competitive antagonist at the nicotinic acetylcholine receptors. (L1256) No indication of carcinogenicity to humans (not listed by IARC). Alcuronium is a type of curare, a plant toxin known for its use as paralyzing arrow poison by South American indigenous people. It can be extracted from a variety of plants, including Strychnos toxifera and Chondrodendron tomentosum. (L1256) Curare is a muscle relaxant that can lead to death from asphyxiation, as the respiratory muscles are unable to contract. (L1256) Curare is a muscle relaxant and thus causes paraylsis. (L1256) The antidote for curare poisoning is an acetylcholinesterase inhibitor (anti-cholinesterase), such as physostigmine or neostigmine.
