Tasectan Diarrhea was developed to control symptoms associated with acute diarrhea, such as frequent bowel movements and abdominal straining. Its main purpose is to protect the intestinal mucosa, promoting the recovery of its physiological function and contributing to a faster resolution of symptoms. It is indicated for children in sachet form and can be used in babies and children according to age and usage recommendations. Its formula contains gelatin tannate, a complex of gelatin and tannic acid that acts through a physical mechanism, without being absorbed by the body. Upon reaching the intestine, it forms a protective film over the inflamed intestinal mucosa, helping to reduce the permeability of the intestinal wall and protect tissues from the aggressions responsible for diarrhea. As it acts locally and does not interfere with intestinal motility, Tasectan helps reduce the frequency of bowel movements and the duration of diarrheal episodes without altering normal intestinal transit. The effect can be observed within the first 12 hours after starting use. The contents of the sachets can be easily mixed with water, milk, fruit juice, yogurt or other foods, facilitating administration in young children. The product can be used in conjunction with oral rehydration solutions, which are essential to prevent dehydration during episodes of diarrhea.
