StarLac® Lactose Monohydrate & Maize Starch Compound

StarLac® Co-processed lactose starch is a filler/binder with strong disintegrant properties. The co-processing offers superior benefit compared to a blend of lactose and starch. It allows to improve the performance (hardness, friability, disintegration time) of your 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 pharmaceutical applications including granules, swallowable tablets, orally dispersible tablets and hard capsules.
