KEFUROX vs RESPORAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefuroxime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting the final transpeptidation step of peptidoglycan synthesis, leading to cell lysis.
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.
750 mg to 1.5 g intramuscularly or intravenously every 8 hours; for severe infections, 1.5 g intravenously every 6 to 8 hours.

1.2-1.6 hours in adults with normal renal function (Clcr >80 mL/min); prolonged to 10-20 hours in end-stage renal disease (Clcr <10 mL/min).
Terminal half-life is 12 hours (range 10-14 h), supporting twice-daily dosing in most patients.
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal <10%.
Renal excretion accounts for 70% of elimination (30% unchanged), biliary/fecal 20%, and 10% metabolized.
