Erythromycin can affect bacterial protein synthesis and is generally effective against Gram-positive bacteria. It is mainly used to treat infections caused by penicillin G-resistant Staphylococcus aureus.



Erythromycin is a motilin receptor agonist. The spatial structure of the Dimethylamine group and 14 lactone ring on the glycoside chain of Erythromycin molecule is similar to that of motilin, which can be used as a motilin receptor agonist to produce a simulated motilin effect, induce the premature contraction of MMC phase III in the fasting state, and cause the contraction of gastric and duodenal smooth muscle. The gastric motility of Erythromycin is related to the dosage. Low dose of Erythromycin induces gastric contraction similar to spontaneous MMC, while large dose of Erythromycin causes strong irregular gastroduodenal contraction and vomiting, which is also the reason why Erythromycin causes gastrointestinal reaction. Therefore, the dosage of Erythromycin for promoting gastric motility should not be too large.
