Frequently Asked Questions
Where can I buy Lactose IP/USP grade for tablet manufacturing in Hyderabad?
Surravi Phharma supplies Lactose in IP, BP, EP, and USP grades in Hyderabad. Suitable for both direct compression and wet granulation. Ready stock. Call +91 8008002576 for pricing and COA.
What grades of Lactose are available for direct compression?
For direct compression, spray-dried Lactose (Lactose DCL or equivalent) and anhydrous Lactose grades are preferred for their superior flowability and compressibility. Standard Lactose Monohydrate is more suited for wet granulation. Specify your process when ordering.
Is Lactose compatible with all active pharmaceutical ingredients?
Lactose is incompatible with primary and secondary amines (Maillard reaction), and with strongly alkaline APIs. It should be avoided in formulations for lactose-intolerant patients or where amine-group APIs are present. It is otherwise highly compatible with most drug substances.
Can Lactose be used as a carrier in dry powder inhalers (DPI)?
Yes. Coarse-grade Lactose Monohydrate is the standard carrier in DPI formulations. API particles (1–5 μm) adhere to the large Lactose carrier particles (50–150 μm) and are released in the airstream during inhalation. Inhalation-grade Lactose has specific surface area and particle size specifications.
