Heparin is an anticoagulant drug used to prevent and treat blood clots in conditions such as deep vein thrombosis, pulmonary embolism, and during surgeries. It is a naturally occurring glycosaminoglycan and is usually administered intravenously or subcutaneously. Heparin is still widely used and is approved for these indications.
Pharmacokinetics
Pharmacokinetic parameters represent typical values in healthy adult individuals after intravenous bolus administration.
