Codeine for diarrhea: Symptomatic Drug

Diarrhea can be explained as a frequent, often precipitate passage of poorly formed stools. The WHO defines the condition as 3 or more loose or watery stools in a period of 24-hours. Pathologically, it can be explained as a condition where the excess passage of water occurs in the feces. This article highlights the uses of Codeine for diarrhea.

Diarrhea can be a cause of 

  • Decreased electrolyte and water absorption
  • Increased secretion by the intestinal mucosa
  • Increased luminal osmotic load 
  • Inflammation of mucosa and exudation into the lumen.

The drugs used for such conditions are known as antidiarrheal drugs.
