DESCRIPTION
Aminophylline Injection, USP is a sterile, nonpyrogenic solution of
aminophylline in water
for injection. Aminophylline (dihydrate) is approximately 79% of
anhydrous theophylline
by weight. Aminophylline Injection is administered by slow intravenous
injection or diluted
and administered by intravenous infusion.
The solution contains no bacteriostat or antimicrobial agent and is
intended for use only
as a single-dose injection. When smaller doses are required the unused
portion should
be discarded.
Aminophylline is a 2:1 complex of theophylline and ethylenediamine.
Theophylline is
structurally classified as a methylxanthine. Aminophylline occurs as a
white or slightly
yellowish granule or powder, with a slight ammoniacal odor.
Aminophylline has the
chemical name 1H-Purine-2, 6-dione, 3,7-dihydro-1,3-dimethyl-,
compound with 1,2-
ethanediamine (2:1). The structural formula of aminophylline
(dihydrate) is as follows:
Aminophylline Injection, USP contains aminophylline (calculated as the
dihydrate) 25
mg/mL (equivalent to 19.7 mg/mL anhydrous theophylline) prepared with
the aid of
ethylenediamine. The solution may contain an excess of ethylenediamine
for pH
adjustment. pH is 8.8 (8.6 to 9.0). The osmolar concentration is 0.17
mOsmol/mL (calc.).
CLINICAL PHARMACOLOGY
Mechanism of Action:Theophylline has two distinct actions in the
airways of patients with
reversible obstruction; smooth muscle relaxation (i.e.,
bronchodilation) and suppression
of the response of the airways to stimuli (i.e., nonbronchodilator
prophylactic effects).
While the mechanisms of action of theophylline are not known with
certainty, studies in
animals suggest that bronchodilation is mediated by the inhibition of
two isozymes of
phosphodiestera
