Triamcinolone acetonide, USP, the active ingredient in Azmacort® (triamcinolone acetonide inhalation aerosol) Inhalation Aerosol, is a corticosteroid used in a inhalation metered-dose aerosol unit.
It is similar to beclomethasone (Vanceril, QVAR) and fluticasone (Flovent) in that it has potent anti-inflammatory actions. Some symptoms of asthma are caused by chronic inflammation in the airways within the lungs that obstruct the flow of air into and out of the lungs. Triamcinolone reduces inflammation in the lungs and airways and thereby improves breathing in individuals with asthma. When used as an inhaler, triamcinolone goes directly to the airways of the lungs, and very little is absorbed into the body.
The triamcinolone inhaler is used for preventing episodes of asthma. It should not be used for acute attacks of asthma because it does not work quickly enough. Azmacort is used to prevent asthma attacks. It will not treat an asthma attack that has already begun.
Use Azmacort exactly as it was prescribed for you. Do not use the medication in larger amounts, or use it for longer than recommended by your doctor. Azmacort comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
