CHOLEDYL SA vs OXTRIPHYLLINE PEDIATRIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Choledyl SA (theophylline, sustained-release) is a methylxanthine that inhibits phosphodiesterase, increasing intracellular cAMP, and blocks adenosine receptors, leading to bronchodilation 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.
400 mg orally every 12 hours (sustained-release); maximum 800 mg every 12 hours.
200 mg orally every 6-8 hours; extended-release: 400-600 mg orally every 12 hours.

Terminal elimination half-life: 7-9 hours in healthy adults; prolonged in hepatic cirrhosis (up to 30 hours), heart failure, COPD, and in neonates; shortened in smokers and cystic fibrosis.
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: 90% as unchanged drug and metabolites (theophylline metabolites including 1,3-dimethyluric acid, 3-methylxanthine, and 1-methyluric acid). Biliary/fecal: <10%.
Renal (70-80% as unchanged drug, 10-15% as metabolites); biliary/fecal (<10%)
