Study Notes
Classification of Laxatives
-
Bulk Forming Laxatives
- Composed of natural or synthetic fibers.
- Includes Psyllium seeds, Methylcellulose, and Polycarbophil.
- Function by absorbing water to increase stool bulk and stimulate bowel movement.
-
Stimulant Laxatives
- Act directly on the intestinal walls to stimulate contractions.
- Key examples are Bisacodyl, Aloe, and Senna.
- Often used for quick relief from constipation.
-
Stool Softeners
- Help to mix fluid into stools, making them easier to pass.
- Common types include Docusate, Glycerin suppository, and Mineral oil.
- Recommended for individuals where strain during bowel movements is the concern.
-
Chloride Channel Activator
- Specifically Lubiprostone.
- Increases intestinal fluid secretion by activating chloride channels.
- Aids in subsequent stool passage, often for chronic constipation.
-
5HT4 Receptor Agonists
- Enhance gastrointestinal motility by activating serotonin receptors.
- Includes Tegaserod, Cisapride, and Prucalopride.
- Useful for individuals with irritable bowel syndrome (IBS) and constipation.
-
Osmotic Laxatives
- Draw water into the intestines to soften the stool.
- Key agents are Magnesium Hydroxide, Sorbitol, Lactulose, and Polyethylene Glycol (PEG).
- Often recommended for safe, effective relief from constipation.
-
Opioid mu Receptor Antagonists
- Counteract opioid-induced constipation by blocking specific receptors in the gut.
- Notable examples include Methylnaltrexone and Alvimopan.
- Administered to patients on opioids who experience constipation as a side effect.
