GENERIC NAME: fluticasone
propionate oral inhaler
¡¡
BRAND NAMES: Flovent
DRUG CLASS AND MECHANISM: Fluticasone propionate is
a man-made steroid of the glucocorticoid family which
is related to the naturally-occurring steroid hormone,
cortisol or hydrocortisone, produced by the adrenal
glands. Glucocorticoid steroids have potent anti- inflammatory
actions. When used as an inhaler, fluticasone propionate
goes directly to the airways of the lung. In asthmatic
patients, the suppression of inflammation within the
airways reduces the spasm that narrows the airways and
makes getting air into and out of the lungs difficult.
When used in lower doses, very little fluticasone propionate
is absorbed into the body. When higher doses are used,
fluticasone is absorbed and may cause side effects elsewhere
in the body.
PRESCRIPTION: yes
GENERIC AVAILABLE: no
PREPARATIONS: Inhalation aerosol unit in
44 µg, 110 µg or 220 µg per actuation.
STORAGE: Fluticasone propionate should be
kept at room temperature, 4-30°C (39-86°F) and should
be shaken well before each use.
PRESCRIBED FOR: Fluticasone propionate is
used for the control of asthma in persons requiring
continuous treatment. Such patients may include those
with frequent asthmatic episodes requiring medications
to dilate (expand) airways or those with asthmatic episodes
at night.
DOSING: Doses vary from patient to patient,
but recommendations for inhalation are similar for most
corticosteroids including fluticasone propionate. The
canister containing the fluticasone propionate should
be shaken well before administering. The lungs are emptied
of air by breathing out completely. The mouthpiece is
placed between the open lips, and the lips are closed
firmly around the mouthpiece. The canister's actuating
valve is depressed one time while breathing in deeply
and slowly. The breath is held for a count of 10, and
then normal breathing is resumed. If more than a single
inhalation is prescribed, a minute should pass between
inhalations.
A tube acting as a spacer, which can be
attached to the canister, may be helpful for persons
who are unable to coordinate breathing in and pressing
down on the canister's valve. Following administration,
the mouth should be rinsed thoroughly with water or
mouthwash which is then spit out to minimize dry mouth,
irritation of the throat, and hoarseness. The inhaler
must be cleaned frequently by removing the canister
and cap from the inhaler and then rinsing the inhaler
with warm water and drying it.
If a bronchodilator aerosol spray (a spray
that causes the airways to expand), for example, albuterol
(Proventil; Ventolin), is used, it should be used first,
and then 5 - 15 minutes later the fluticasone propionate
should be used.
DRUG INTERACTIONS: No drug interactions
have been described with inhaled fluticasone propionate.
PREGNANCY: Adequate and well-controlled
studies regarding the use of fluticasone during pregnancy
have not been done. Fluticasone use during pregnancy
should be avoided unless the potential benefit justifies
the potential but unknown risk to the fetus.
NURSING MOTHERS: It is not known if fluticasone
propionate is secreted in breast milk. Other medications
in the same class as fluticasone propionate are secreted
into breast milk. 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 fluticasone propionate
are mild cough or wheezing; these effects may be minimized
by using a bronchodilator inhaler (e.g. albuterol or
Ventolin) first. Oral candidiasis or thrush (a fungal
infection) may occur in between 1 in 50 and 1 in 20
persons who use fluticasone propionate (without a spacer),
the risk being higher with higher doses. The risk for
candidiasis in children is lower than in adults. Using
a spacer and washing the mouth out with water following
each use reduces the risk of candidiasis. Hoarseness
may also occur, and here also, a spacer and washing
the mouth out with water following each use reduces
the risk.
High doses of inhaled glucocorticoids may
decrease formation and increase break-down of bone thereby
weakening bones and promoting fractures. Still higher
doses may cause suppression of the body's ability to
make its own natural glucocorticoid in the adrenal gland.
It is possible that these effects are shared by higher-dose
fluticasone propionate. People with suppression of their
adrenal glands (which can be diagnosed by a doctor)
would need increased amounts of glucocorticoids, probably
by the oral or intravenous route, during periods of
high physical stress when glucocorticoids are particularly
important.
