Protamine sulfate is a medication that is used to reverse the effects of heparin. [3] It is specifically used in heparin overdose , in low molecular weight heparin overdose , and to reverse the effects of heparin during delivery and heart surgery .
Protamine sulfate [51] Table 1: antidotes for cardiovascular agent overdose For patients taking antihyperlipidemic agents, liver function tests have to be conducted before and during the therapy to monitor the elevation of liver enzymes which may result in hepatotoxicity , especially for those undergoing statin therapy .

Protamine sulfate is an antidote for heparin overdose, but severe allergy may occur. [10] A chain shortened version of protamine also acts as a potent heparin antagonist, but with markedly reduced antigenicity.
The first step in management of a protamine reaction is to immediately stop the protamine infusion. Corticosteroids are used for all types of protamine reactions. Chlorphenamine is used for type II (anaphylactic) reactions. For type III reactions, heparin is redosed and the patient may need to go back on bypass. [13]
Protamine insulin was first created in 1936 and NPH insulin in 1946. [1] It is on the World Health Organization's List of Essential Medicines. [4] NPH is an abbreviation for "neutral protamine Hagedorn". [1] In 2020, insulin isophane was the 221st most commonly prescribed medication in the United States, with more than 2 million prescriptions.
Hepatin's anticoagulant effects are typically reversible with protamine sulfate, while protamine's effect on LMWH is limited. LMWH has less of an effect on thrombin than heparin, but about the same effect on Factor Xa. Due to its renal clearance, LMWH is contraindicated in patients with kidney disease who can safely use unfractionated heparin.

HuffPost and The Chronicle examined 201 public D-I schools from 2010-2014. Schools are ranked based on the percentage of their athletic budget that comes from subsidies.
An increased risk of stroke and non-CNS embolism was observed in rivaroxaban-treated patients compared with warfarin-treated patients after the end of the study, underscoring the importance of therapeutic anticoagulation coverage during such a transition. Agnelli, Giancarlo (2005).
