Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and disrupting peptidoglycan cross-linking. This leads to cell lysis and death, primarily in actively dividing bacteria.
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.
For uncomplicated infections: 1-2 g IV every 8 hours. For severe infections: up to 2 g IV every 4 hours. Administered as an IV infusion over 30-60 minutes.

1.8 hours (normal renal function); prolonged to 10-30 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.
Renal: >80% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <1%
Renal excretion accounts for 70% of elimination (30% unchanged), biliary/fecal 20%, and 10% metabolized.
