LANOPHYLLIN vs THEOBID JR.
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.
Inhibits phosphodiesterase, increasing intracellular cAMP; causes bronchodilation, central nervous system stimulation, and positive inotropic/chronotropic 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.
300 mg orally every 12 hours, extended-release tablet. Titrate to serum theophylline concentration of 5-15 mcg/mL.

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.
3-8 hours in adults; prolonged in neonates, cirrhosis, heart failure (up to 30 hours). Tobacco smoking induces clearance (half-life 4-5 hours).
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%).
Hepatic metabolism (90%), renal excretion of unchanged drug (10%). Metabolites excreted in urine.
