Materials andMethods: Elderly subjects (n = 48) with chief complaint of constipation were enrolled in a randomly double-blind study. The subjects were divided into 2 groups: control group, receiving placebo every 8 hours for one month, and study group, receiving lactobacillus acidophilus tablet every 8 hours for onemonth. Subjectswith lactose intolerance and other pathologic conditions were omitted.At the end of 4 weeks, all subjects were questioned on the relief of constipation and other symptoms. Response to treatment and complications were compared between the two groups.

Results: In subjects receiving lactobacillus acidophilus, 50%(13 subjects) respondedwell and had relief of constipation, 23.1%(6 subjects) showed relative response and 26.9%(7 subjects) did not respond. In subjects receiving placebo, 40% (6 subjects) had relief of constipation, 13.3% (2 subjects) responded relatively well and in 46.7% (7 subjects) no responsewas seen (p=0.388).Newsignswere observed in 5 subjects (19.2%) receiving lactobacillus acidophilus and 1 subject (6.7%) receiving placebo.After 4 weeks, 2 subjects (7.7%) receiving lactobacillus acidophilus and 1 subject (6.7%) receiving placebo re-experienced constipation.
