MICROCRYSTALLINE CELLULOSE AND CALCIUM PHOSPHATE COMPOSITIONS USEFUL AS PHARMACEUTICAL EXCIPIENTS

摘要

Coprocessed compositions containing calcium phosphate and microcrystalline cellulose are useful as excipients in the preparation of solid dosage forms containing active pharmaceutical ingredients, particularly those prepared by processes involving multiple compaction steps. Such compositions may be obtained by preparing aqueous slurries of microcrystalline cellulose and calcium phosphate and drying such slurries to produce particulate products. The coprocessed products exhibit improved compactibility, as compared to dry physical blends of the same components.
