Dulcolax pico perles are used to provide relief from constipation. It ensures a gentle yet effective laxative effect in 6 to 12 hours. It works by stimulating both the colon and the rectum. It also helps bowel to return to normal regular function. This liquid contains sodium picosulfate as the prime ingredient.Sodium picosulfate acts by stimulating the nerve endings in the walls of the large intestine (colon) and rectum. This causes the muscles in the intestinal wall to contract more often and with increased force. When these muscles contract, this moves the contents of the intestine through the colon to the rectum so that the bowel can be emptied.It only gets activated by the natural bacteria that are found in the colon, so it does not start working until it reaches this part of the gut. These small gel capsules are easy to swallow and can be precisely dosed according to your individual needs.
