WebMotilin Receptor Agonists. Motilin receptor agonists include the antibiotic erythromycin and other agents—none of which is commonly available—that act as motilin receptor ligands on smooth muscle cells and enteric nerves. The pharmacodynamic effects in humans are dose dependent. Erythromycin and related antibiotics act as non-peptide motilin agonists, and are sometimes used for their ability to stimulate gastrointestinal motility. In the case of erythromycin, it is its hemiketal intermediate, formed after an oral dose in the low-pH environment of the stomach lumen, which directly acts on the motilin receptor. Administration of a low dose of erythromycin will induce peristalsis, which provides additional support for the conclusion that motilin secretion triggers thi…
