During the double-blind, placebo-controlled clinical trial, 6 cases of necrotizing enterocolitis developed among the 85 infants studied (caffeine=46, placebo=39), with 3 cases resulting in death. Five of the six patients with necrotizing enterocolitis were randomized to or had been exposed to CAFCIT (caffeine citrate).
Reports in the published literature have raised a question regarding the possible association between the use of methylxanthines and development of necrotizing enterocolitis, although a causal relationship between methylxanthine use and necrotizing enterocolitis has not been established. Therefore, as with all preterm infants, patients being treated with CAFCIT should be carefully monitored for the development of necrotizing enterocolitis.
There is currently no manufacturer warning information available for this drug.
CAFCIT (caffeine citrate) is indicated for the short-term treatment of apnea of prematurity in infants between 28 and <33 weeks gestational age.
Both CAFCIT® (caffeine citrate) Injection for intravenous administration and CAFCIT® (caffeine citrate) Oral Solution 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 5.0 mg citric acid monohydrate, 8.3 mg sodium citrate dihydrate and Water for Injection.
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-1H-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.
