Caffeine citrate: when and for how long. A literature review.

The efficacy of caffeine in an episode of Apnoea of Prematurity (AOP) has been known for over thirty years. Its use over long periods of time has not only found it to be manageable within the field of neonatology, but it has also been found to have other favourable actions, such as reducing the incidence of extubation failure, preventing Bronchopulmonary Dysplasia (BPD), reducing the need for Patent Ductus Arteriosus treatment and the beneficial effect it has on Retinopathy of Prematurity. Recent in vitro trials have highlighted the neuroprotective role that caffeine plays, which has already partly been observed from in vivo trials. Just recently, caffeine citrate has become a "label" drug and it would be beneficial if more studies could confirm the more significant effects it has on the more severe conditions of prematurity.
