It is used in food manufacturing as a nutritive sweetener and is approximately 35% as sweet as table sugar (i.e. [sucrose]). Clinically, lactitol has been investigated for use as an osmotic laxative and, along with other non-absorbable disaccharides such as [lactulose], in the treatment of hepatic encephalopathy in patients with cirrhosis.  Pizensy, an oral lactitol powder for solution, was approved by the FDA for use in chronic idiopathic constipation in February 2020."}]
