Summary for Patent: 3,897,779
| Title: | Triamcinolone acetonide inhalation therapy |
| Abstract: | An aerosol container carrier and deceleration chamber for dispensing powdered triamcinolone acetonide with inhaled particles predominantly below 10 microns in size at a low velocity gives a comparatively high degree of topical effect in the lungs as compared with systemic effect from triamcinolone acetonide absorbed in the mouth or upper throat. The suspension of triamcinolone acetonide in dichlorodifluoromethane is preferably subjected to sonic waves at about -40*C, resulting in a suspension having increased physical stability. A suspending agent such as anhydrous ethanol or sorbitan trioleate also increases stability. |
