Products
Gelatin tannate is commercially available in the form of a powder and as capsules (Tasectan). It is approved as a medical device, not a drug, and is therefore less extensively studied.
Structure and properties
Gelatin tannate is a complex consisting of gelatin and tannic acid. It is stable in the stomach and breaks down into its components only in the intestine. Binding to gelatin prevents irritant effects of tannic acid in the stomach. Tannic acid is a polymer of gallic acid and glucose.
Effects
Gelatin tannate has antidiarrheal, astringent, and antimicrobial properties and binds enterotoxins. The effects are primarily due to the formation of a protective layer on the intestinal mucosa.
Indications for use
For symptomatic treatment of diarrhea.
Dosage
According to the package insert.
Contraindications
Gelatin tannate is contraindicated in case of hypersensitivity. Refer to the package insert for complete precautions.
