Phenylpropanolamine is a decongestant. It works by
constricting (shrinking) blood vessels (veins and arteries) in your
body. Constriction of blood vessels in your sinuses, nose, and chest
allows drainage of those areas, which decreases congestion.
Phenylpropanolamine is used to treat the congestion associated with
allergies, hay fever, sinus irritation, and the common cold.
Phenylpropanolamine also causes a decrease in appetite and is used
in some over-the-counter diet aids.
Phenylpropanolamine has been associated with an increased risk of
hemorrhagic stroke (bleeding into the brain or into tissue
surrounding the brain) in women. Men may also be at risk. Although
the risk of hemorrhagic stroke is low, the U.S. Food and Drug
Administration (FDA) recommends that consumers not use any products
that contain phenylpropanolamine.
Additional Information
DEA scheduled list 1 chemical. Subject to procurement quota
requirements
Phenylpropanolamine (PPA;
Accutrim, Dexatrim), also knwon as norephedrine
and oxyamphetamine, is a
psychoactive drug of the
phenethylamine and
amphetamine
chemical classes which is used as a
stimulant,
decongestant, and
anorectic agent.[1][2]
It is commonly used in
prescription and
over-the-counter
cough and cold preparations. In
veterinary medicine, it is used to control
urinary incontinence in dogs under
trade names Propalin and Proin.
PPA acts as a
potent and
selective
releasing agent of
norepinephrine and
epinephrine, or as a
norepinephrine releasing agent (NRA). It also acts as a
dopamine releasing agent (DRA) to a lesser extent.
INTERACTIONS WITH OTHER DRUGS
In some cases of urinary incontinence, phenylpropanolamine is used
in combination with diethylstilbesterol (an estrogen). No harmful
drug interactions are expected with this combination.
Phenylpropanolamine should not be used with L-Deprenyl (Anipryl) due
to resulting unpredictable fluctuations in blood pressure.
It is recommended that phenylpropanolamine be withdrawn for 2 weeks
preceding the use of L-Deprenyl.
An increased risk of hypertension can also occur if
phenylpropanolamine is given in conjunction with tricyclic
antidepressants (such as amitriptyline), non-steroidal
anti-inflammatory drugs (NSAIDs), or amitraz (active ingredient of
the Preventic tick control collar and canine Promeris, a flea
control product).
Storage Information
LIGHT SENSITIVE: Keep tightly closed in light-resistant containers.
The Food and Drug Administration (FDA) has
taken steps to remove phenylpropanolamine from all drug products and
has issued a public health advisory concerning phenylpropanolamine
hydrochloride. This drug is an ingredient used in many
over-the-counter (OTC) and prescription cough and cold medications
as a decongestant and in over-the-counter weight loss products.
Phenylpropanolamine has been found to increase the risk of
hemorrhagic stroke (bleeding into the brain or into tissue
surrounding the brain) in women. Men may also be at risk. Although
the risk of hemorrhagic stroke is very low, FDA recommends that
consumers not use any products that contain phenylpropanolamine.
