OMNICEF vs RESPORAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalosporin antibiotic; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
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.
300 mg orally twice daily for 10 days; or 600 mg orally once daily for 10 days (for community-acquired pneumonia, acute exacerbations of chronic bronchitis, sinusitis, pharyngitis/tonsillitis, uncomplicated skin infections).

1.7 hours (range 1.2–2.3 h) in healthy adults; prolonged to 3.2–6.6 h in renal impairment (CrCl <30 mL/min); no significant change in hepatic impairment.
Terminal half-life is 12 hours (range 10-14 h), supporting twice-daily dosing in most patients.
Renal excretion as unchanged drug: 80-90% (primarily via glomerular filtration and tubular secretion); biliary/fecal: 10-20% (minor).
Renal excretion accounts for 70% of elimination (30% unchanged), biliary/fecal 20%, and 10% metabolized.
