Dose conversion from aminophylline to theophylline in preterm infants
J Reese, G Prentice and VY Yu
Monash Medical Centre, Clayton, Victoria, Australia.
Twenty two preterm infants were prospectively evaluated to assess the need
for dose adjustment when converting enteral and parenteral routes of
methylxanthine administration. Serum theophylline concentrations remained
unchanged in 18 infants after conversion from intravenous aminophylline to
theophylline by mouth with dose reduction, as is currently recommended.
Intravenous aminophylline and theophylline by mouth may therefore be
prescribed at equivalent doses, with a possible reduction in drug errors,
and improved stability of serum concentrations.
