MEDIA MILLING PROCESS FOR THE MANUFACTURE OF ACTIVE PHARMACEUTICAL INGREDIENTS IN PROPELLANTS

摘要

The invention disclosed herein is a novel media milling process performed in an atmosphere of propellants(s) utilizing a resonant acoustic mixing (RAM) device. The process is utilized to reduce the particle size of API (optionally including excipients) to a respirable size range while ensuring the retention of the crystallinity of the milled API.

主权项

1. A milling process comprising (A) adding an API, in the presence or absence of excipients and/or additives, and beads to a container; (B) sealing the container and filling with propellant media; and (C) mixing the container with an acoustic mixing device.
