Kinevac (sincalide for injection)/Squibb Diagnostics.
Sincalide is a rapid-acting, synthetic analog of cholecystokinin for intravenous use in postevacuation cholecystography. Serious reactions to sincalide have not been reported. The intravenous administration of sincalide causes a prompt contraction of the gallbladder as compared to the stimulus of a fatty meal which causes progressive contraction that becomes maximal in about 40 minutes. The use of Kinevac to accelerate the transit time through the small bowel decreases the time and extent of radiation associated with fluoroscopy and length of the x-ray examination of the intestinal tract. Duodenal aspiration obtained after the administration of Kinevac provides a sample of concentrated bile for analysis of cholesterol, bile salts, phospholipids and crystals. When used in conjunction with secretin to stimulate pancreatic secretion, an aspirate is readily obtained for analysis of enzyme activity, composition and cytology. As the development of endoscopic manometry affords a modality to measure and record sphincter of Oddi pressures, the paradoxical responses noted to the intravenous administration of CCK during manometric evaluation supports the diagnostic value of Kinevac used as a provocative agent in the evaluation of biliary dyskinesia.
