[The treatment of acute diarrhea].

Racecadotril has sufficient proven efficacy in the treatment of acute diarrhea in children. Treatment outcomes in adults are less convincing. The place of gelatin tannate is unclear. Some sources point to potential hepatotoxicity and diminished iron absorption, with a concomitant risk of anemia, at least in case of excessive or prolonged use. Loperamide still has a prominent place in the treatment of acute and chronic diarrhea. Attention should be payed to correct dosing and some well-known contra-indications. Probiotics are indicated in children, as well as in the prevention of antibiotics-induced diarrhea. There is no evidence to support their use in the treatment of acute diarrhea in adults. Up till now publications disagree on the efficacy in the prevention of travelers' diarrhea. Astringents and absorbents are no longer supported in guidelines. Oral rehydration systems have a part to play in pediatric treatment.
