Pancreatic Enzyme Secretion

The article presents the results of a study of the effectiveness of the use of an inhibitor of pancreatic enzyme secretion of octreotide (Octrade) for the prevention of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). It was shown that the administration of Octrade at a dose of 0.3 mg in 500 ml of 0.9 % NaCl by continuous intravenous infusion for 7 hours and then 0.1 mg of Octrade subcutaneously at 6 and 12 hours after the end of intravenous infusion significantly reduced the frequency of pancreatitis (4.0 % and 22.2 %; p < 0.05) and hyperamylasemia (8.0 % and 25.9 %; p < 0.05) after ERCP. It is concluded that Octrade is effective in preventing the development of pancreatitis and hyperamilasemia after ERCP.

Dose Dependent

In rat pancreatic slices, rat pancreatic polypeptide (PP) or C-terminal hexapeptide of PP [PP-(31-36)] inhibited potassium-stimulated amylase release in a dose-dependent manner. The inhibition was unaffected by addition of hexamethonium but blocked by atropine. In contrast, PP(31-36) did not have any effect on acetylcholine- or cholecystokinin octapeptide-stimulated amylase release. In addition, when pancreatic slices were incubated with [3H] choline, PP(31-36) inhibited the potassium-evoked release of synthesized [3H] acetylcholine in a dose-dependent manner. The inhibitory action of PP was unaffected by adrenergic, dopaminergic, or opioid receptor antagonists. Thus PP inhibits pancreatic enzyme secretion via presynaptic modulation of acetylcholine release. This newly identified pathway provides a novel mechanism for hormonal inhibition of pancreatic enzyme secretion via modulation of the classic neurotransmitter function.
