NCI Drug Dictionary


glycerin enema 
An enema solution containing 5% glycerin, a trihydroxy alcohol with osmotic laxative activity. Upon rectal administration, glycerin enema creates an osmotic gradient thereby attracting water into the rectum. This increases volume, increases peristalsis, stimulates evacuation, and relieves constipation. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
