strychnine(redirected from Strychnia)
Also found in: Dictionary, Thesaurus, Encyclopedia.
a very poisonous alkaloid from seeds of Strychnos nux-vomica and other species of Strychnos; a common strychnine-containing rodenticide causes convulsions in humans.
An alkaloid from Strychnos nux-vomica; colorless crystals of intensely bitter taste, nearly insoluble in water. It stimulates all parts of the CNS, and was used as a stomachic, an antidote for depressant poisons, and in the treatment of myocarditis. Strychnine blocks the inhibitory neurotransmitter glycine, and thus can cause convulsions. The formerly used salts of strychnine are strychnine hydrochloride, strychnine phosphate, and strychnine sulfate. It is a potent chemical capable of producing acute or chronic poisoning of humans or animals.
strychnine/strych·nine/ (strik´nīn) a very poisonous alkaloid, obtained chiefly from Strychnos nux-vomica and other species of Strychnos, which causes excitation of all portions of the central nervous system by blocking postsynaptic inhibition of neural impulses.

strychnineToxicology A highly toxic alkaloid from Strychnos nux-vomica, commonly used as a rodenticide, that elicits CNS hyperactivity, causing painful, recurrent tonic seizures, muscle tightness, cramping, risus sardonicus, marked flaccidity, decorticate posturing and death; Sx appear at 15 mg, death occurs with doses > 60 mg Management Control seizures with diazepam and phenobarbital; for muscle relaxation, curare, succinylcholine

strychnineA bitter-tasting, highly poisonous substance occurring in the seeds of Strychnos species of tropical trees and shrubs. Poisoning causes restlessness, stiffness of the face and neck, exaggerated sensations, extreme arching of the back (opisthotonus) and death from paralysis of breathing unless artificial ventilation is used.
strychninea poisonous alkaloid obtained from Strychnus nux-vomica, used as a stimulus for the CNS.
a very poisonous alkaloid from seeds of the plant Strychnos nux-vomica and other species of Strychnos. A commonly used compound in malicious poisoning of dogs and used as a feral animal bait to which domestic dogs find access. The dogs may also be poisoned by eating the vermin. Clinical findings include tetanic convulsions especially in response to external stimuli.
