Proglumide hemicalcium 

Proglumide hemicalcium is a nonpeptide and orally active cholecystokinin (CCK)-A/B receptors antagonist. Proglumide hemicalcium selective blocks CCK’s effects in the central nervous system (CNS). Proglumide hemicalcium has ability to inhibit gastric secretion and to protect the gastroduodenal mucosa. Proglumide hemicalcium also has antiepileptic and antioxidant activities^{[1][2][3][4][5]}.

Cholecystokinin (CCK)-A/B receptors^[1][2]

In an in vitro study, Proglumide at concentrations between 0.3-10 mM inhibits CCK-stimulated amylase release dose-dependently, while Proglumide does not influence the basal amylase release at concentrations between 0-3 mM. Dose-response curves to CCK for amylase release shifted to the right with increase in Proglumide concentration. This inhibition by Proglumide is reversible. In addition, the effect of Proglumide is selective for CCK and its related peptide^[2].
The incubation of HT29 cells with Proglumide significantly reduces the [³H]-thymidine incorporation to HT29 cells in a dose-dependent manner, with an IC₅₀ of 6.5 mM. Proglumide reduces in a dose-dependent manner the percentage of necrosis with a parallel increase of apoptosis up to 70%^[3].

Proglumide (250-750 mg/kg; intraperitoneal injection; adult male Sprague Dawley rats) treatment is significantly effective in ameliorating the seizure activities, cognitive dysfunctions, and cerebral oxidative stress^[1].
