Methods for making pharmaceutical formulations comprising microparticles with improved dispersibility, suspendability or wettability
First Claim
1. A method for making a dry powder blend pharmaceutical formulation, comprising the steps of:
- (a) providing microparticles which comprise a pharmaceutical agent;
(b) blending the microparticles with at least one excipient in the form of particles to form a powder blend; and
(c) jet milling the powder blend to form a dry powder blend pharmaceutical formulation having improved dispersibility, suspendability, or wettability as compared to the microparticles of step (a) or the powder blend of step (b).

Abstract
Methods are provided for making a dry powder blend pharmaceutical formulation, comprising the steps of: (a) providing microparticles which comprise a pharmaceutical agent; (b) blending the microparticles with at least one excipient in the form of particles to form a powder blend; and (c) jet milling the powder blend to form a dry powder blend pharmaceutical formulation having improved dispersibility, suspendability, or wettability as compared to the microparticles of step (a) or the powder blend of step (b). The method can further include dispersing the dry powder blend pharmaceutical formulation in a liquid pharmaceutically acceptable vehicle to make an formulation suitable for injection. Alternatively, the method can further include processing the dry powder blend pharmaceutical formulation into a solid oral dosage form. In one embodiment, the microparticles of step (a) are formed by a solvent precipitation or crystallization process.
