Application

PEARLITOL® 200 GT mannitol is a direct compression excipient, specially designed to avoid capping, improve flowability and tabletability. It is a granulated form of mannitol with exceptional physical and chemical stability. It offers high API compatibility and no hygroscopicity. It is also a non-cariogenic and non-acidogenic sugar-free sweetener. It is suitable in formulations addressing all types of patient populations including pediatric and diabetic. It can be used in tablets (lozenges, swallowable tablets, orally dispersible tablets, chewable tablets, and effervescent tablets) and in powder blends (sachets, oral stick pack and hard gelatin capsules filling).
