Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and cross-linking of peptidoglycan. It has broad-spectrum activity against gram-negative and gram-positive bacteria, including anaerobes, and is resistant to beta-lactamases.
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.

2.8-3.2 hours in normal renal function; prolonged to 12-30 hours in severe renal impairment (CrCl <10 mL/min).
Terminal half-life is 12 hours (range 10-14 h), supporting twice-daily dosing in most patients.
Primarily renal (76-85% unchanged in urine via glomerular filtration and tubular secretion); biliary excretion accounts for <10%, with small amounts in feces.
Renal excretion accounts for 70% of elimination (30% unchanged), biliary/fecal 20%, and 10% metabolized.
