  • MEDIA MILLING PROCESS FOR THE MANUFACTURE OF ACTIVE PHARMACEUTICAL INGREDIENTS IN PROPELLANTS
    Publication number: 20160317391
    Abstract: 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.
