Renzapride (BRL 24924), a substituted benzamide, is a full 5-HT4 receptor agonist with a Ki value of 115 nM. Renzapride (BRL 24924) is also a 5HT2b and 5HT3 receptor antagonist[1]. Renzapride could be used for constipation predominant irritable bowel syndrome (C-IBS) study[2]. | [in vivo]
Renzapride (BRL 24924) (100 μg i.v.) results in a partial reverse of both the delayed solid and liquid meals emptying[2].
Renzapride (BRL 24924) (0.5-1 mg/kg) significantly increases the rate of emptying of a 51Cr-labeled liquid meal from the murine stomach[4]. | Animal Model: | Dog (simulating gastroparesis)[2] | | Dosage: | 100 μg/kg | | Administration: | i.v. | | Result: | Results in a partial reverse of both the delayed solid and liquid meals emptying.
