A group of drugs used to treat constipation. There are various types. Bulk-forming laxatives increase the volume and softness of faeces and make them easier to pass. Stimulant laxatives stimulate the intestinal wall to contract and speed up the elimination of faeces. Lubricant laxatives soften and facilitate the passage of faeces. Osmotic laxatives increase the water content and volume of the faeces. If used in excess, laxative drugs may cause diarrhoea, abdominal cramps, and flatulence, and may impair normal bowel function.
