Product overview

Thru-lac S is a stimulant laxative formulated with two active ingredients that help sluggish intestinal motility. Bisacodyl and sennoside calcium each stimulate the intestine through different actions and are used to relieve constipation and related symptoms. The tablets are coated so the active ingredients reach the intestine before working, and the dose can be adjusted to match your symptoms.

Product features

01

Two active ingredients with different actions

Bisacodyl acts on peristalsis from the upper large intestine, while sennoside calcium is activated by intestinal bacteria to promote peristalsis. A formula that supports intestinal motility through different pathways.

Coated so it does not dissolve in the stomach and reaches the intestine before working. Designed so the active ingredients act at the intended site.

03

Dose adjustable to your symptoms
