Comment on Roquette product benefits
StarLac® co-processed lactose starch is a filler/binder having strong disintegrant properties. The co-processing offers superior benefit compared to a blend of lactose and starch, which allows you to improve the performance (hardness, friability, disintegration time) of your existing formulation. Specifically designed for direct compression applications, StarLac® is also an excellent filler/binder in dry granulation processes. StarLac® can be used in various oral dosage forms in both pharmaceutical and nutraceutical applications including granules, swallowable tablets, orally dispersible tablets and hard capsules.
StarLac® is EP/USP-NF compliant.
StarLac® is a product co-marketed by Meggle and Roquette. StarLac® is a registered trademark of Meggle AG.
