    Product Description

    Amthamine is a histamine H2 receptor agonist (pD2 = 6.21 in isolated guinea pig atria).1 It is selective for H2 over H3 receptors (pD2 = 4.7 in isolated guinea pig ileum). Amthamine increases heart rate in spontaneously beating isolated guinea pig atria (pD2 = 6.72) and decreases contractions induced by cholecystokinin (CCK) octapeptide in a dose-dependent manner in isolated guinea pig gallbladder strips.2,3 It increases sheep red blood cell-induced production of IgG and IgM antibodies in rabbit serum when administered at a dose of 10 µg/kg twice per day.4

    WARNING This product is not for human or veterinary use.
