Treatment: Drugs - Caffeine citrate injection
Treatment: Drugs - placebo
Active Comparator: caffeine -
Placebo Comparator: placebo -
Treatment: Drugs: Caffeine citrate injection
Loading dose: 20 mg/kg administered over at least 30 minutes via IV infusion or over at least 10 minutes via slow IV injection.
Daily maintenance dose (to commence at least 24 hours after loading dose): 5 mg/kg, administered over at least 10 minutes via IV infusion, or over at least 5 minutes via slow IV injection.

Summary
Brief summary
Apnea of prematurity is a common condition that is usually treated with methylxanthines.
Methylxanthines are adenosine receptor blockers that have powerful influences on the central
nervous system. However, little is known about the long-term effects of methylxanthines on
the developing brain.
The Caffeine for Apnea of Prematurity-Sleep (CAP-S) Study is a sub-study of the main Caffeine
for Apnea of Prematurity (CAP) trial, an international placebo-controlled randomized trial of
methylxanthine therapy for apnea of prematurity. This sub-study is designed to take advantage
of this cohort of ex-premature, 5-7 year old children who were randomized at birth to receive
either caffeine or placebo, and are currently receiving detailed neurocognitive and
behavioral assessments in the CAP trial.
