A double-blind, randomized, dose response study testing the pharmacological efficacy of synthetic porcine secretin

Background: Biologically derived porcine secretin has been used as a diagnostic agent in clinical gastrointestinal practice for many years. Pure synthetic porcine secretin is now available for investigational clinical use. Aim: To compare the pharmacology of synthetic porcine secretin and biologically derived porcine secretin in healthy volunteers. Methods: Secretin stimulation tests were performed in 12 volunteer subjects in a double-blind, randomized, Latin square crossover design study comparing three doses of synthetic porcine secretin (0.05, 0.2, and 0.4 μg/kg) with a standard dose of biologically derived porcine secretin (1 CU/kg). Duodenal aspirates were analysed for total volume and…
