An open-label, prospective clinical study to evaluate the efficacy and safety of TLPL/AY/01/2008 in the management of functional constipation

J Ayurveda Integr Med. 2011 Jul;2(3):144-52. doi: 10.4103/0975-9476.85554.


Functional constipation is one of the most common gastrointestinal symptoms across the globe. Its high prevalence rate, economic burden, and adverse implications on the quality of life make constipation a major public health issue. Though various treatment options are available for the management of constipation, evidence for their efficacy and safety are limited. An open-label, prospective, interventional, and exploratory clinical trial was carried out to evaluate the efficacy and safety of "TLPL/AY/01/2008" in 34 patients suffering from functional constipation. "TLPL/AY/01/2008" is an Ayurvedic proprietary polyherbal formulation in powder form, containing Isabgol husk, Senna extract, and Triphala extract. Administration of "TLPL/AY/01/2008" for 14 days showed a significant increase in mean weekly bowel movements from 10.19 ± 05.64 to 18.29 ± 05.72 (P<0.05). The mean average time spent on toilet for bowel evacuation reduced significantly from 11.02 ± 05.43 minutes (baseline value) to 08.70 ± 04.72 minutes on day 14 (P<0.05). Mean stool form score assessed on Bristol stool form scale was improved from 02.97 ± 00.48 (baseline value) to 04.61 ± 00.84 (P<0.05) on day 14. A significant improvement (P<0.05) was also noted in straining during defecation, sensation of incomplete evacuation, sensation of anorectal blockage, and other associated symptoms of functional constipation. The significant improvement in most of the above symptoms was endured for a post-treatment observatory period of one week. All the study patients showed an excellent tolerability to the study drug. These findings suggest that "TLPL/AY/01/2008" is an effective, safe, and non-habit-forming herbal laxative formulation for the management of constipation. Comparative clinical studies with larger sample size would be able to confirm the above findings.
