It is generally recommended that oral rehydration should be used as first-line therapy to treat or prevent dehydration in children with acute gastroenteritis (AGE). Despite the proven efficacy of oral rehydration therapy it remains underused. The main reason for this is that an ORS neither reduces the frequency of bowel movements and fluid loss nor shortens the duration of illness, which decreases its acceptance. Moreover, unpalatability of regular ORS decrease its acceptance, especially in children with lower degrees of dehydration. Refusal to drink regular ORS interfere with compliance with the recommended treatment. Parents, but also health care professionals, demand safe, effective, inexpensive, but also well tolerated and accepted ORS for management of AGE.
