title: Enhancement of pentagastrin-induced gastric acid secretion by clonidine in the conscious dog.
abstract: The effect of intravenous clonidine on pentagastrin-induced gastric acid secretion has been studied in conscious dogs with Heidenhain pouches. Dose-dependent enhancement of secretion was found in response to clonidine (5-20 mu/kg). Clonidine (20 mug/kg) increased the maximal secretory rate to pentagastrin to a value not significantly different from the maximal response to histamine.
