GENERIC NAME: triamcinolone
acetonide inhaler
DRUG CLASS AND MECHANISM: Triamcinolone acetonide is
a synthetic (man-made) steroid of the glucocorticoid
family. The naturally-occurring glucocorticoid hormone
is cortisol or hydrocortisone, and it is produced in
the adrenal glands. Glucocorticoid steroids have potent
anti-inflammatory actions. When used as an inhaler,
the medication goes directly to the airways of the lungs,
and very little is absorbed into the body.
PRESCRIPTION: yes
GENERIC AVAILABLE: no
PREPARATIONS: Inhaler 100 mcg/actuation.
STORAGE: Triamcinolone acetonide should
be kept at room temperature, 15-30<C (59-86<F) and protected
for direct light.
PRESCRIBED FOR: Triamcinolone acetonide
is indicated for the control of bronchial asthma
in persons requiring continuous treatment.
Such patients may include those with frequent asthmatic
episodes requiring bronchodilators or those with asthmatic
episodes at night.
DOSING: Triamcinolone acetonide is used
for the prevention of asthmatic attacks and should not
be used to treat acute (active) attacks. Doses vary
widely. Two to four inhalations or more may be prescribed
two to four times daily. The medication requires continuous
(daily) use to be effective. Some benefit may be noted
by the third day of use, but maximal benefit usually
is not seen until the second or third week of use.
DRUG INTERACTIONS: No drug interactions
have been described with inhaled triamcinolone acetonide.
PREGNANCY: When given orally, glucocorticoids
such as triamcinolone have been shown to cause fetal
abnormalities in animals; however, it is not known if
there is an increased risk of malformation in children
born to mothers exposed to triamcinolone acetonide during
pregnancy.
NURSING MOTHERS: It is not known if triamcinolone
acetonide is secreted in breast milk. Other medications
in this class are secreted into breast milk, but it
is not known whether the small amounts that may appear
in the milk are of consequence to the infant.
SIDE EFFECTS: The most commonly noted side
effects associated with inhaled triamcinolone acetonide
are mild cough or wheezing; these effects may be minimized
by using a bronchodilator inhaler (e.g. albuterol or
Ventolin) prior to triamcinolone acetonide. Oral candidiasis
or thrush (a fungal infection) may occur in 1 in 20
to 1 in 10 persons who use triamcinolone acetonide,
the risk being higher with higher doses. The risk in
children is lower than in adults. Hoarseness also may
result from the use of triamcinolone acetonide. Using
a spacer device and washing the mouth out with water
following each use reduces the risk of thrush and hoarseness.
Hoarseness also may occur.
High doses of other inhaled glucocorticoids
may decrease bone formation and increase bone breakdown
(resorption) leading to weak bones and fractures. Very
high doses may cause suppression of the body's ability
to make its own natural glucocorticoid in the adrenal
glands. It is possible that patients with suppression
of their adrenal glands may need increased amounts of
glucocorticoids by the oral or intravenous route during
periods of high physical stress.
