Abstract

Unfractionated heparin is used in medicine as an anticoagulant to prevent blood clotting. In life-threatening emergencies when fast reversal of the anticoagulant action of heparin is necessary, protamine – an agent approved in 1939 – is available as an antidote. The biological origin of protamine, which is isolated from salmon sperm, is probably responsible for its considerable toxicity, which manifests itself as arterial hypotension, catastrophic pulmonary vasoconstriction or severe, sometimes lethal, anaphylactic reaction. Consequently, safer alternatives have been sought for many years. The most promising antidote currently in an advanced stage of development is andexanet alfa. In the present review, we discuss the major deleterious effects of protamine and list agents, presently in the research phase, with the potential to neutralize the action of parenteral anticoagulants.
