Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Caspofungin inhibits the synthesis of β-(1,3)-D-glucan, an essential component of the fungal cell wall, by noncompetitive inhibition of the enzyme β-(1,3)-D-glucan synthase, leading to osmotic instability and cell death.
Caspofungin acetate is an echinocandin antifungal that inhibits the synthesis of 1,3-beta-D-glucan, an essential component of the fungal cell wall, by noncompetitively inhibiting the enzyme 1,3-beta-D-glucan synthase. This leads to osmotic instability and cell lysis, primarily against Candida and Aspergillus species.
70 mg IV once, followed by 50 mg IV once daily thereafter.
Adults: 70 mg IV loading dose on day 1, then 50 mg IV once daily.

The terminal elimination half-life is approximately 40–50 hours in adults. A multi-exponential decline is observed; the beta half-life is 9–11 hours, and the gamma (terminal) half-life is 40–50 hours. This supports once-daily dosing after a loading dose.
Terminal elimination half-life ~9-11 hours in adults, with a prolonged terminal phase (beta half-life 40-50 hours) due to slow tissue distribution and redistribution. Clinically, dosing interval is 24 hours.
Renal excretion of unchanged drug is minimal (approximately 1% of dose). The primary route of elimination is biliary/fecal, with about 70% of a radiolabeled dose recovered in feces over 14 days, mostly as metabolites. Urinary excretion accounts for about 10% of total radioactivity, primarily as metabolites.
Primarily hepatic: slow metabolism with subsequent biliary and fecal excretion. ~35% of administered dose excreted in feces and ~41% in urine over 27 days, with <2% unchanged in urine. Minimal renal excretion as unchanged drug.
