Laxatives: Types, Dosage & Side Effects
Laxatives, often referred to as “luxatives,” play a crucial role in managing constipation and other digestive issues. Lets understand about Laxatives: Types, Dosage & Side Effects.
Types of Laxatives
Laxatives come in various forms, each with its unique mechanism of action:
- Bulk-forming Laxatives: These laxatives work by adding bulk to the stool, softening it and promoting bowel movements. Common examples include psyllium husk and methylcellulose.
- Stimulant Laxatives: Stimulants directly affect the muscles in the intestines, prompting contractions and bowel movements. Senna and bisacodyl are typical stimulant laxatives.
- Osmotic Laxatives: These laxatives draw water into the intestines, softening the stool and stimulating bowel movements. Magnesium hydroxide and lactulose are examples of osmotic laxatives.
- Stool Softeners: Stool softeners, such as docusate sodium, make the stool easier to pass by adding moisture to it.
- Lubricant Laxatives: Lubricants coat the stool, making it slippery and easier to pass. Mineral oil is a common lubricant laxative.
How Laxatives Work
Each type of laxative has a unique mechanism of action:
- Bulk-forming laxatives add mass to the stool.
- Stimulant laxatives irritate the intestines, causing contractions.
- Osmotic laxatives draw water into the intestines.
- Stool softeners add moisture to the stool.
- Lubricant laxatives make the stool slippery.
