The efficacy and adverse reactions of Maren Runchang Pills among patients of different genders remain unclear. This study aims to analyze the efficacy and safety differences of Maren Runchang Pills in patients of different genders, providing a basis for the implementation of gender-precise treatment in clinical practice. Gender-stratified analysis was adopted to include constipation-predominant irritable bowel syndrome (IBS-C) patients who met the syndrome of intestinal heat and accumulation. The efficacy and safety of Maren Runchang Pills were evaluated after 4 weeks of treatment. The main evaluation indicators include the complete spontaneous bowel movement response rates, visual analogue scale scores for abdominal pain and distension, traditional Chinese medicine syndrome scores, irritable bowel syndrome-symptom severity scale/irritable bowel syndrome-quality of life scale scores, and safety indicators. A total of 126 patients were included, among whom 101 were female and 25 were male. After 4 weeks of treatment, the proportion of female patients with a complete spontaneous bowel movement response rate of ≥75% was significantly higher than that of male patients (71.29% vs 48%, P = .0270), and the improvement in abdominal distension visual analogue scale score was also significantly better in females (decrease of 2.78 points vs 1.84 points, P = .0199). However, the total score of traditional Chinese medicine syndromes in male patients was higher than that in female patients (7.08 points vs 5.09 points, P = .0341). There were no statistically significant differences in the scores of the irritable bowel syndrome-symptom severity scale, irritable bowel syndrome-quality of life scale and safety indicators between the 2 groups. Maren Runchang Pills can effectively alleviate the constipation symptoms of patients with IBS-C, and the therapeutic effect is even better in female patients. The research results support considering gender factors in the clinical treatment of IBS-C to achieve individualized and precise intervention.
