as a single-dose injection. When smaller doses are required the unused
portion should
be discarded.

structurally classified as a methylxanthine. Aminophylline occurs as a
white or slightly

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:

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,
