Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive inhibition of plasminogen activation and, to a lesser extent, noncompetitive inhibition of plasmin, thereby preventing fibrinolysis and promoting clot stability.
Aprotinin is a serine protease inhibitor that forms reversible enzyme-inhibitor complexes with trypsin, plasmin, kallikrein, and chymotrypsin, thereby inhibiting fibrinolysis and reducing perioperative blood loss.
4-5 g orally or intravenously as a loading dose, followed by 1 g/hour continuous infusion or 1 g every 4-6 hours orally. Maximum dose 30 g/day.
1,000,000 KIU (kallikrein inhibitor units) IV loading dose over 10 minutes, followed by 250,000 KIU/hour continuous IV infusion during surgery; also 1,000,000 KIU added to cardiopulmonary bypass circuit prime volume.

Clinical Note
moderateAminocaproic acid + Tretinoin
"Aminocaproic acid may increase the thrombogenic activities of Tretinoin."
Terminal elimination half-life: 2 hours (normal renal function); prolonged to 4–10 hours in renal impairment. Clinically, dosing interval must be adjusted in renal dysfunction to avoid accumulation.
Terminal elimination half-life approximately 2 hours (alpha phase) and 10-12 hours (beta phase); prolongation in renal impairment.
Primarily renal (>95%) as unchanged drug via glomerular filtration and tubular secretion. Less than 1% biliary/fecal.
Primarily renal excretion; 70-80% of aprotinin is eliminated unchanged in urine within 48 hours; minor biliary/fecal elimination (<5%).
