RESPORAL vs ROCEPHIN KIT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
RESPORAL contains theophylline, a methylxanthine that inhibits phosphodiesterase (PDE) isoenzymes, leading to increased intracellular cAMP and cGMP levels. It also antagonizes adenosine receptors, resulting in bronchodilation and anti-inflammatory effects.
Ceftriaxone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis and death.

Terminal half-life is 12 hours (range 10-14 h), supporting twice-daily dosing in most patients.
Terminal half-life 6-9 hours in healthy adults; prolonged to 12-15 hours in elderly and up to 30 hours in severe renal impairment (CrCl <10 mL/min).
Renal excretion accounts for 70% of elimination (30% unchanged), biliary/fecal 20%, and 10% metabolized.
Renal (33-67% unchanged), biliary (40-50% as active drug and metabolites), fecal (minor).
