Product Overview
“Korak II” is a rich-formulation laxative in Taisho Pharmaceutical’s Korak series. Its two-ingredient formulation addresses constipation: the active ingredient bisacodyl directly stimulates the large intestine to enhance peristaltic movement, while DSS (dioctyl sodium sulfosuccinate) allows water to penetrate hardened stool and soften it appropriately. The dosage is designed to be adjustable according to your bowel movements, and starting with the minimum dose the first time is recommended.
Product Features
01
Contains bisacodyl to directly stimulate the large intestine
Large-intestine stimulation
Bisacodyl directly stimulates and activates peristaltic movement in the large intestine, enhancing reduced intestinal activity. Its unique five-layer coating allows it to reach and act in the large intestine without dissolving in the stomach.
02
Contains DSS to soften hard stool
Stool softening
DSS (dioctyl sodium sulfosuccinate) allows water to penetrate hard stool and soften it appropriately. Its two-step action—stimulating the large intestine and softening stool—helps create conditions for easier passage.
03
A wide range of doses that you can adjust yourself
Dose adjustment
You can adjust the dose according to your bowel movements. Start with the minimum dose the first time and gradually adjust it while checking the effect. Once your bowel movements improve, reduce the dose or increase the interval between doses.
✦
Small Tablets with a five-layer coating
Small pink Tablets with a special five-layer coating so that the active ingredients do not dissolve in the stomach but act in the large intestine.
✦
Take whole without chewing
Take the tablets whole with water or lukewarm water without chewing or crushing them.
