DESCRIPTION
Both Caffeine Citrate Injection, USP for intravenous administration
and Caffeine Citrate Oral Solution,
USP are clear, colorless, sterile, non-pyrogenic, preservative-free,
aqueous solutions 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.
