Compound of Lactose Monohydrate USP/NF, EP, JP and Hypromellose USP/NF, EP, JP

RetaLac is a co-processed excipient comprising of equal parts of milled alpha-lactose monohydrate and hypromellose (USP substitution type 2208) with a nominal viscosity of 4000 cps. It is manufactured by a specialized spray-agglomeration process which generates textured and highly structured free flowing particles which are partially soluble in cold water.
