Tag: Protamine

As an essential medication for reversing the effects of heparin, protamine is officially classified as an anticoagulant reversal agent, or more specifically, a heparin antagonist. This basic protein is crucial for managing and reversing heparin-induced anticoagulation in various critical care scenarios.

Protamine is a highly basic protein historically obtained from the sperm, or milt, of salmon and other fish species. This surprising origin answers the question: **What drug comes from salmon sperm?** It has been used in medicine for decades, primarily to neutralize the effects of the blood-thinner heparin.
