Yohimbine increases plasma insulin concentrations and reverses xylazine-induced hypoinsulinemia in dogs. 1988

Xylazine (1.1 mg/kg of body weight, IV), an alpha 2-adrenoreceptor agonist, suppressed the increase in plasma insulin concentration induced by glucose (0.6 g/kg, IV) in dogs. Yohimbine (0.11 mg/kg, IV), an alpha 2-adrenoreceptor antagonist, given 5 minutes after xylazine, reversed effects of xylazine, whereas yohimbine alone increased plasma insulin and decreased plasma glucose concentrations. Seemingly, alpha 2-adrenoreceptors exert a negative control of insulin release.

UI	MeSH Term	Description	Entries
D007328	Insulin	A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).
