Classification of Purgatives and Laxatives (Constipation, Or Diarrhea relief Drugs)

Purgatives and laxatives are substances that help promote bowel movements and relieve constipation. They can be classified into several categories based on their mechanism of action. Here's an overview: 1. Bulk-Forming Laxatives Mechanism: Increase the bulk of stool by absorbing water, which stimulates bowel movements. Examples: Psyllium (Metamucil), Methylcellulose (Citrucel), Polycarbophil (FiberCon). 2. Osmotic Laxatives Mechanism: Draw water into the bowel to soften the stool and increase bowel movement. Examples: Lactulose, Polyethylene Glycol (MiraLAX), Magnesium Hydroxide (Milk of Magnesia). 3. Stimulant Laxatives Mechanism: Stimulate the intestinal wall to increase bowel contractions. Examples: Bisacodyl (Dulcolax), Senna (Senokot), Sodium Picosulfate. 4. Stool Softeners (Emollient Laxatives) Mechanism: Add moisture to the stool, making it easier to pass. Examples: Docusate Sodium (Colace), Docusate Calcium (Surfak). 5. Lubricant Laxatives Mechanism: Coat the stool and the intestinal wall with a waterproof film, which keeps moisture in the stool. Examples: Mineral Oil. 6. Saline Laxatives Mechanism: Attract and retain water in the intestine, increasing the pressure within the bowel and stimulating bowel movements. Examples: Magnesium Citrate, Sodium Phosphates (Fleet Enema). 7. Hyperosmolar Laxatives Mechanism: Increase the water content in the stool by drawing water into the intestine. Examples: Glycerin Suppositories, Sorbitol. #Purgatives #Laxatives
