実験手順

A formulation of tacrolimus (TAC) was produced using TAC and lactose (LAC) in ratio 1:1. The TAC:LAC 1:1 formulation was prepared using the ultra-rapid freezing (URF) process. The compositions were prepared by dissolving TAC and LAC at a 1:1 ratio and 0.75% solids in a 60/40 mixture of acetonitrile and water. The solution of drug and excipient was applied to the surface of a solid substrate, which is cooled using a cryogenic substrate maintained at −50° C. The frozen compositions were then collected and the solvent was removed by lyophilization using a VirTis Advantage Lyophilizer (VirTis Company, Inc. Gardiner, N.Y.). The dried powders were stored at room temperature under vacuum.
