Release of "Colac II," a New Product in the Colac Series




Taisho Pharmaceutical Co., Ltd. (President: Akira Uehara) will release a new laxative, Colac II on November 26. It softens hardened stools due to constipation and improves bowel movement.

Colac II contains an emollient laxative, dioctyl sodium sulfosuccinate (DSS), which improves bowel movement by providing moisture to a hard stool and softening it to an adequate level. It also contains a stimulant laxative, bisacodyl, which directly stimulates the large intestine and promotes peristalsis, and as such is very effective against constipation. 

The dose can be adjusted in accordance with the level of bowel movement. People who have not previously used Colac should begin by taking one pill only. Colac is a small pink pill, which is easy to take.
Laxatives need to exert their effects in the intestine. The active ingredients in Colac II, bisacodyl and DSS, are covered with five layers of coating, thus preventing them being released in the stomach and ensuring that they are released into the intestine. 

Up to now, we have launched five products in the Colac series for the treatment of constipation and conditions arising from constipation. The release of Colac II as a new product in the Colac series is a response to the needs of consumers, and we continue to respond to ever-diversifying consumer needs.
