1. What is Atolaxant and what is it used for

Atolaxant is a laxative used for the treatment of constipation (especially long-lasting constipation) in adults, adolescents, and elderly patients. It is not recommended for children under 12 years of age.

It is also used for the treatment of hard stools that have accumulated in the intestine as a result of long-lasting constipation (this is known as fecal impaction).

The active ingredient Macrogol 3350 softens the stools, making them pass more easily, relieving constipation. The electrolytes (salts) help maintain normal sodium, potassium, and water levels in your body while you are being treated for constipation.
