Secret Formula for Diarrhea
The mechanism of action of anti-diarrheal drugs is:
① By enhancing gastrointestinal smooth muscle tone and reducing intestinal motility, making feces drier and thus stopping diarrhea. Commonly used drugs include opiate preparations, diphenoxylate hydrochloride, and loperamide;
② Through adsorption or astringent effects, preventing abnormal fermentation in the intestine, reducing absorption of toxins in the intestine and irritation to the intestinal mucosa, or directly protecting the intestinal mucosa and reducing exudation to achieve anti-diarrheal effects. For example, after oral administration of tannic protein, it does not decompose in the stomach but breaks down into tannic acid in the small intestine, exerting an astringent effect. This causes coagulation of proteins on the surface of inflamed cells, forming a protective membrane that reduces exudate and alleviates irritation from intestinal contents on the intestinal wall, thereby decreasing intestinal motility. Thus, it has anti-inflammatory, analgesic, and anti-diarrheal effects. Commonly used drugs include tannic protein, subcarbonate zinc, and medicinal charcoal.
Diarrhea is merely a symptom of various diseases, with diverse etiologies. Food poisoning, bacterial infection, indigestion, intestinal dysfunction, endocrine disorders, and hepatic, biliary, and pancreatic insufficiency can all cause diarrhea. For instance, enteritis and dysentery are intestinal infections caused by bacteria; the resulting diarrhea is a response triggered by bacterial toxins stimulating the intestines, which helps expel toxins and bacterial poisons and thus has protective significance. In such cases, anti-diarrheal drugs should not be used; instead, antibacterial treatment should be prioritized, such as taking antibiotics like Antibiotik, norfloxacin, or gentamicin.
However, severe and persistent diarrhea may lead to dehydration and electrolyte imbalance. In such situations, anti-diarrheal drugs may be appropriately administered alongside etiological treatment.
Therefore, one should not automatically administer anti-diarrheal drugs upon seeing diarrhea; treatment should be based on specific circumstances and target the underlying cause. Generally, anti-diarrheal drugs are mainly used for non-bacterial-induced diarrhea.<diarrhea>
