Protam is mainly used as an antagonist of the effects of heparin, which is a blood thinner often used during surgical procedures or in certain cases to prevent blood clotting. When heparin is given in excessive doses or when there is a need to stop its effect, Protam is given as an antagonist of these effects, as it works to neutralize heparin and reduce the risk of excessive bleeding.
Protam can be used in other medical contexts that require control of blood clotting levels, especially in major surgical procedures that involve the use of anticoagulants. It is usually given intravenously under close medical supervision, where the dose is carefully determined based on the amount of heparin given and the extent of its effect that needs to be stopped.
