AMINOCAPROIC ACID vs TRASYLOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive inhibition of plasminogen activation, reducing fibrinolysis by binding to plasminogen and blocking its conversion to plasmin.
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.
Loading dose: 4-5 g intravenously (IV) over 1 hour, followed by continuous IV infusion of 1 g/hour for 8 hours or until bleeding controlled. Oral: 1 g every hour for 8 hours, then 1 g every 2 hours for 8 additional hours.
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 is approximately 2 hours (range 1-3 hours) in patients with normal renal function. Prolonged in renal impairment (up to 20 hours in anuria).
Terminal elimination half-life approximately 2 hours (alpha phase) and 10-12 hours (beta phase); prolongation in renal impairment.
Primarily renal (80-90% unchanged). A small fraction (<5%) is excreted as metabolites. No significant biliary/fecal elimination.
Primarily renal excretion; 70-80% of aprotinin is eliminated unchanged in urine within 48 hours; minor biliary/fecal elimination (<5%).
