Tuvatidine (HUK 978) is a potent H2-antagonist. HUK 978 was shown to be devoid of activity at the histamine H1-receptor, the muscarinic receptor and the alpha and beta-adrenergic receptors. In both the guinea-pig gastric mucosa preparation and the rat perfused stomach model, HUK 978 was a powerful inhibitor of acid secretion. HUK 978 is a highly specific H2-antagonist and inhibits acid secretion for longer periods than other competitive compounds.

Sample Use Guides

In Vivo Use Guide

Dogs: The effect of the continuous intravenous infusion of different doses of HUK 978 (0.02 to 0.06 uM/kg/h). At doses close to the ID50 values, HUK 978 (0.07 uM/kg) gave almost twice the inhibition at 120 min post dose compared to cimetidine.

Route of Administration: Intragastric

In Vitro Use Guide

Tuvatidine (HUK 978) inhibited histamine stimulated adenylate cyclase from guinea-pig gastric fundic mucosa in a dose dependent manner. HUK 978 had no effect on the unstimulated basal activity of adenylate cyclase. Analysis by the method of Schild from six separate experiments gave a mean KB value of 4.8 x 10(-8) M with a slope of 1.03 showing the antagonism to be competitive. Using membranes prepared from guinea-pig cerebral cortex, HUK 978 inhibited 3H-tiotidine binding with a Ki of 2.0 x 10(-8) M.
