LANOPHYLLIN vs OXTRIPHYLLINE PEDIATRIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lanophyllin is a xanthine derivative that inhibits phosphodiesterase, leading to increased intracellular cyclic AMP levels. It also antagonizes adenosine receptors, resulting in bronchodilation, respiratory stimulation, and anti-inflammatory effects.
Xanthine derivative that inhibits phosphodiesterase, increasing cyclic AMP levels; antagonizes adenosine receptors, leading to bronchodilation, central nervous system stimulation, and positive inotropic effects.
5-6 mg/kg IV loading dose over 20-30 minutes, then 0.4-0.6 mg/kg/hour continuous IV infusion; maintenance oral dose 300-600 mg/day in divided doses every 8-12 hours.
200 mg orally every 6-8 hours; extended-release: 400-600 mg orally every 12 hours.

Terminal elimination half-life is 7-9 hours in healthy adults; increases to 20-30 hours in congestive heart failure, cirrhosis, or severe COPD; decreases to 3-5 hours in smokers (tobacco or marijuana) due to enzyme induction.
Neonates: 24-36 hours; Infants 1-6 months: 14-29 hours; Children 6-12 months: 9-18 hours; Children 1-9 years: 3-6 hours; Adults: 7-12 hours. Half-life prolonged in hepatic impairment, CHF, and COPD.
Renal excretion of unchanged drug accounts for approximately 10% of elimination; hepatic metabolism accounts for 90%, with metabolites excreted in urine. Biliary/fecal excretion is negligible (<2%).
Renal (70-80% as unchanged drug, 10-15% as metabolites); biliary/fecal (<10%)
