_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:
The molecular formula of aminophylline dihydrate is C
H
N
O
• 2(H
O) with a molecular
weight of 456.46.
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
