Caffeine is a first line treatment for neonatal apnea due to its metabolites' ( theophyllines) effects on the lungs and breathing rate. Oral administration of medication in neonates is difficult for several reasons. Poor swallowing and GI compromise often lead to unpredictable and erratic dosing. This makes transdermal delivery of medications an ideal and promising choice. Studies have shown that caffeine applied twice daily in gel formulation in neonates is sufficient to maintain therapeutic levels of caffeine while avoiding oral dosing complications.
