Objective To evaluate the effects of Medilac-S combined with Lactulose on treating functional constipation in geriatrics.Methods 90 cases（60 to 75 years old） suffering from functional constipation and meeting all the inclusion criteria were recruited and randomly divided into three groups of each 30 cases： group A（combination therapy group,given Medilac-S,500mg/time,2 times/day combined with Lactulose,15ml/time,2 times/day）,group B（Medilac-S singlely treated group,administered with Medilac-S,500mg/time,2 times/day）,and group C（Lactulose singlely treated group,administered with Lactulose,15ml/time,2 times/day）.The changes of weekly bowel movements,stool form score,average time spent on toilet for bowel evacuation and VAS score of associated symptoms of functional constipation were observed after two and four weeks treating,and the treatment lasted for four weeks.Results After 4 weeks’ clinical therapy,the total effective rates of remission were 86.67%,43.33%,53.33% in group A,B,C respectively.Compared with group B or C,group A showed a significant increase in mean weekly bowel movements and mean stool form score,meanwhile,a significant decrease in mean average time spent on toilet for bowel evacuation and VAS score of associated symptoms of functional constipation（P＆lt;0.05）.Conclution Clinical effects of Medilac-S combined with Lactulose on treating functional constipation in geriatrics are better than that of single drug,and the therapeutic benefits are obvious,safe,worthy of clinical application.
