Application of azithromycin in preparing medicines for treating functional weak peristalsis

The invention provides an application of azithromycin in preparing medicines for treating functional weak peristalsis, wherein the molecular structural formula of the azithromycin is as shown in Description; the azithromycin, without affecting mice weight, can significantly promote peristalsis capacity of a weak peristalsis model, and can increase defecation times and defecation weight; and in addition, with the application of the azithromycin, defecation indexes of a mouse of the weak peristalsis model can rapidly reach a normal level; therefore, the azithromycin has a good effect on treating the functional weak peristalsis. 本发明提供了阿奇霉素在治疗功能性肠蠕动乏力的药物中的应用，其中，所述阿奇霉素分子结构式为：在不影响小鼠体重的情况下，阿奇霉素可显著的促进肠蠕动乏力模型的肠蠕动能力，增加排便次数及排便重量，并能很快的使肠蠕动乏力模型小鼠的排便指标达到正常水平，对功能性肠蠕动乏力具有很好的治疗效果。
