CARDRASE vs CARNEXIV
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CARDRASE is a nonsteroidal anti-inflammatory drug that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing the synthesis of prostaglandins involved in inflammation, pain, and fever.
CARNEXIV is a formulation of carbidopa and levodopa; levodopa is converted to dopamine in the brain, replenishing depleted dopamine in the striatum, while carbidopa inhibits peripheral decarboxylation of levodopa, increasing central availability.
Adult: 100 mg orally twice daily.
1 mg intravenously once daily for 7 days, followed by 1 mg orally once daily for 7 days.

Terminal elimination half-life is 12-15 hours in adults with normal renal function; prolonged to 24-40 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 8-12 hours in patients with normal renal function; prolonged in renal impairment (up to 24-36 hours with CrCl <30 mL/min)
Primarily renal excretion of unchanged drug (60-70%) and glucuronide conjugate (10-20%); biliary/fecal elimination accounts for 10-15%.
Renal (approximately 70% as unchanged drug and metabolites), biliary/fecal (approximately 25-30%)
