Protamine sulfate replaced hexadimethrine bromide (Polybrene), another cationic agent that was the original heparin reversal agent in the early days of heart surgery, until studies in the 1960s suggested that hexadimethrine bromide might cause kidney failure when used in doses in excess of its therapeutic range.
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 . [ 52 ]
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.
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.
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.
The Prescribing Information follows one of two formats: "physician labeling rule" format or "old" (non-PLR) format. For "old" format labeling a "product title" may be listed first and may include the proprietary name (if any), the nonproprietary name, dosage form(s), and other information about the product.
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]
Midodrine is a prodrug which forms the active metabolite, desglymidodrine, which is an α 1-adrenergic receptor agonist and exerts its actions via activation of α 1-adrenergic receptors of the arteriolar and venous vasculature, producing an increase in vascular tone and elevation of blood pressure.
