5 Cards in this Set

  • Front
  • Back
Uses synthetic or natural polysaccharides and cellulose derivatives to absorb water into the fecal mass to add bulk, e.g.: plantago seed (psyllium seed)
Bulk-forming
Prevents excessive absorption of water from the feces thus delaying drying of the feces, e.g.: mineral oil, Haley’s MO
Lubricant
Lowers the surface tension of the feces which helps water and fatty substances to penetrate the feces, e.g.: doucasate sodium (Colace)
Wetting Agents
Irritates the intestinal mucosa causing increased peristalsis and rapid expulsion of feces, e.g.: castor oil, cascara sagrada,
bisacodyl (Dulcolax, Bisco-lax), senna
Stimulant
Uses salts, which are poorly absorbed in the intestine, to draw fluid into the intestine which increases fecal bulk and possibly lubricates the feces, e.g.: magnesium sulfate (Epsom salts), magnesium hydroxide (Milk of Magnesia), magnesium citrate
Saline
