What is triamcinolone acetonide nasal inhaler-spray, and how does it work (mechanism of action)?

Triamcinolone acetonide is a synthetic (man-made) corticosteroid. It is administered either as an oral metered-dose inhaler for the treatment of asthma (Azmacort), as a topical preparation for the skin (Kenalog; Aristocort) or as a nasal spray (Nasacort AQ) for relieving symptoms of rhinitis. Corticosteroids are naturally occurring hormones produced by the adrenal glands that prevent or suppress inflammation and immune responses. When given by intranasal spray, triamcinolone acetonide provides relief from allergy-induced watery nasal discharge (rhinorrhea), nasal congestion, postnasal drip, sneezing, and itching of the back of the throat which are symptoms associated with allergy. Approximately 50% of the triamcinolone acetonide is absorbed into the blood. A beneficial response usually is noted within a few days but can take as long as 4 weeks. The FDA approved Nasacort in July 1991.
