Tarazepide is a potent and specific CCK-A receptor antagonist.
Tarazepide decreases duodenal electric activity, reduces interdigestive pancreatic secretion, especially protein; reduces cephalic and early postprandial (milk) induced secretion of bicarbonate and protein.Pancreatic protein secretion to intravenous CCK-8 was little affected by atropine, but was significantly reduced by Tarazepide±Atropine; in contrast, protein secretion to intraduodenal CCK-8 was abolished by Tarazepide or atropine[1]. Leptin is administered to the animals at doses of 0.1, 1.0 or 10.0 μg/kg i.d. Tarazepide (2.5 mg/kg, i.d.), a CCK(1) receptor antagonist, is given to the rats prior to the application of leptin. CCK plasma level is measured by radioimmunoassay (RIA) following administration of leptin to the rats. Intraduodenal administration of leptin (1.0 or 10.0 microg/kg) to the fasted rats significantly and dose-dependently increases pancreatic protein and amylase outputs. Pancreatic secretory responses to leptin were totally abolished by prior capsaicin deactivation of sensory nerves or by pretreatment of the rats with Tarazepide[2].

Animal experiment: | Calve[1] The 5 to 7-day-old Friesian male calves (42.0±1.5 kg body weight) are used. The study is made on four calves. After recording 2 to 3 preprandial (interdigestive) MMC/PPS cycles, Tarazepide suspension (0.05, 0.5 and 5.0 mg/kg body weight), or vehicle alone (1% methylcellulose) is infused intraduodenally (i.d.). |

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
