CEFTAROLINE FOSAMIL vs RESPORAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftaroline fosamil is a prodrug that is converted to the active metabolite ceftaroline. Ceftaroline inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), including PBP2a in MRSA and PBP2x in Streptococcus pneumoniae, thereby preventing cross-linking of peptidoglycan.
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.

Terminal elimination half-life is approximately 2.6 hours in patients with normal renal function. This supports twice-daily dosing in most infections.
Terminal half-life is 12 hours (range 10-14 h), supporting twice-daily dosing in most patients.
Renal excretion of unchanged ceftaroline accounts for approximately 88% of the administered dose. Biliary/fecal elimination is minimal (<6%).
Renal excretion accounts for 70% of elimination (30% unchanged), biliary/fecal 20%, and 10% metabolized.
