DESCRIPTION
Caffeine citrate injection, USP for intravenous administration is a
clear, colorless, sterile,
non-pyrogenic, preservative-free, aqueous solution adjusted to pH 4.7.
Each mL
contains 20 mg caffeine citrate (equivalent to 10 mg of caffeine base)
prepared in
solution by the addition of 10 mg caffeine anhydrous to 5 mg citric
acid monohydrate,
8.3 mg sodium citrate dihydrate and Water for Injection, USP.
Caffeine, a central nervous system stimulant, is an odorless white
crystalline powder or
granule, with a bitter taste. It is sparingly soluble in water and
ethanol at room
temperature. The chemical name of caffeine is
3,7-dihydro-1,3,7-trimethyl-1_H_-purine-
2,6-dione. In the presence of citric acid it forms caffeine citrate
salt in solution. The
structural formula and molecular weight of caffeine citrate follows.
CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
Caffeine is structurally related to other methylxanthines,
theophylline, and theobromine.
It is a bronchial smooth muscle relaxant, a CNS stimulant, a cardiac
muscle stimulant,
and a diuretic.
Although the mechanism of action of caffeine in apnea of prematurity
is not known,
several mechanisms have been hypothesized. These include: (1)
stimulation of the
respiratory center, (2) increased minute ventilation, (3) decreased
threshold to
hypercapnia, (4) increased response to hypercapnia, (5) increased
skeletal muscle tone,
(6) decreased diaphragmatic fatigue, (7) increased metabolic rate, and
(8) increased
oxygen consumption.
Most of these effects have been attributed to antagonism of adenosine
receptors, both
A and A subtypes, by caffeine, which has been demonstrated in receptor
binding

assays and observed at concentrations approximating those achieved
therapeutically.
