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.

Is triamcinolone acetonide nasal inhaler-spray safe to take if I’m pregnant or breastfeeding?
Serious complications (including
cleft palate and still
births) have been reported when oral corticosteroids were administered
during
pregnancy. It is not known if the small amounts of corticosteroids that appear
in the blood following intranasal use carry the same risk. Triamcinolone
acetonide use during pregnancy should be avoided unless the physician feels that
the potential therapeutic benefit justifies the potential risk to the fetus.
