Abstract
Constipation is the most common digestive complaint in the general population. Anthranoid laxatives are easily available, not expensive and are among the most sold drugs, but no randomized placebo-controlled studies have been performed to assess their effectiveness and safety in patients with chronic constipation.
Methods/Aims
Aim of this study was to evaluate the effect of once-daily administration of an infusion prepared using a commercially available mixture of herbs containing anthranoid laxatives (HAM: herbal anthranoid mixture) taken in the evening before bedtime for 10 days in patients with chronic constipation. We conducted a double-blind randomized placebo-controlled cross-over study, on patients with chronic constipation according with the Roma III criteria. The patients were randomly divided (1:1) into two arms, according to a cross-over protocol. Arm A received a 10 days treatment (HAM), no therapy for 10 days and placebo for other 10 days. Arm B received placebo for 10 days, no therapy for 10 days and HAM for the other 10 days.
Results
A significant difference (p<0.001) was found between HAM and placebo periods regarding stool frequency after ten days of treatment [mean difference of 5.05 (95% CI: 3.5–6.49)]. Only one patient in arm A discontinued the treatment after three days for the appearance of watery diarrhea that disappeared in 24 hours.
Conclusion
In this double-blind randomized placebo-controlled cross-over pilot study, HAM seems to offer an advantage in chronic constipation improving stool frequency without important side effects, showing that anthranoid laxatives are effective and safe.
