Guanethidine sulphate was synthesized in 1959. Guanethidine is thought to lowing blood pressure by interfering with the metabolism of chemical transmitter substances in post-ganglionic sympathetic nerve fibres.

Name	guanethidine
Synonyms	Guanethidinum Octadine GUANETHIDINE (2-<Octahydroazocinyl-(1)>-ethyl)-guanidin Oktadin [2-(hexahydro-1-(2H)-azocinyl)ethyl]guanidine Isobarin Sanotensin 2-[2-(azocan-1-yl)ethyl]guanidine Oktatenzin (2-azocan-1-yl-ethyl)-guanidine Ismelin Eutensol guanethedine Abapresin

Description	Guanethidine sulphate was synthesized in 1959. Guanethidine is thought to lowing blood pressure by interfering with the metabolism of chemical transmitter substances in post-ganglionic sympathetic nerve fibres.
In Vitro	Ablation of sympathetic fibers is associated with a loss of rat endothelial cell marker (RECA), but no significant effect of guanethidine was found on the survival of endothelial cells and mesenchymal stem cells in vitro[1]. .
In Vivo	Guanethidine (30 mg/kg, s.c., 1 h) unaffected IL-18 hypernociception in TNFR1(-/-) mice as a sympathetic blocker[2]. . Animal Model: Wild-type (WT) Balb/c,TNFR1(-/-)and IFN-γ-γ(-/-) mice[2]. Dosage: 30 mg/kg Administration: Guanethidine (30 mg/kg, s.c., 1 h, diluted in saline) Result: Pre-treatment with guanethidine (sympathetic blocker) unaffected IL-18 hypernociception in TNFR1(-/-) mice.
