This enzyme, the “sodium pump,” is responsible for maintaining the intracellular milieu throughout the body by moving sodium ions out of and potassium ions into cells. By inhibiting Na-K ATPase, digoxin.
  • It causes increased availability of intracellular calcium in the myocardium and conduction system, with consequent increased inotropy, increased automaticity, and reduced conduction velocity
  • It indirectly causes parasympathetic stimulation of the autonomic nervous system, with consequent effects on the sino-atrial (SA) and atrioventricular (AV) nodes
  • It reduces catecholamine reuptake at nerve terminals, rendering blood vessels more sensitive to endogenous or exogenous catecholamines
  • It increases baroreceptor sensitization, with consequent increased carotid sinus nerve activity and enhanced sympathetic withdrawal for any given increment in mean arterial pressure
  • It increases (at higher concentrations) sympathetic outflow from the central nervous system (CNS) to both cardiac and peripheral sympathetic nerves
  • It allows (at higher concentrations) progressive efflux of intracellular potassium, with consequent increase in serum potassium levels.

The t ½ of the activator complex is about 23 minutes; the complex is inactivated, in part, by antistreptococcal antibodies. The mechanism by which dissociated streptokinase is eliminated is clearance by sites in the liver; however, no metabolites of streptokinase have been identified. Plasmin degrades fibrin clots as well as fibrinogen and other plasma proteins. Plasmin is inactivated by circulating inhibitors, such as (alpha)-2-plasmin inhibitor or (alpha)-2-macroglobulin. These inhibitors are rapidly consumed at high doses of streptokinase.
  • Intravenous administration has been shown to reduce blood pressure and total peripheral resistance with a corresponding reduction in cardiac afterload.
  • Intravenous infusion of Streptokinase is followed by increased fibrinolytic activity, which decreases plasma fibrinogen levels for 24 to 36 hours. The decrease in plasma fibrinogen is associated with decreases in plasma and blood viscosity and red blood cell aggregation. The hyperfibrinolytic effect disappears within a few hours after discontinuation, but a prolonged thrombin time may persist for up to 24 hours due to the decrease in plasma levels of fibrinogen and an increase in the amount of circulating fibrin(ogen) degradation products (FDP). Depending upon the dosage and duration of infusion of Streptokinase, the thrombin time will decrease to less than two times the normal control value within 4 hours, and return to normal by 24 hours.

It is indicated for the treatment of mild to moderate heart failure in adults. Moreover, it increases left ventricular ejection fraction and improves heart failure symptoms as evidenced by improved exercise capacity and decreased heart failure-related hospitalizations and emergency care, while having no effect on mortality. Where possible, it should be used in combination with a diuretic and an angiotensin-converting enzyme (ACE) inhibitor.
Heart Failure in Pediatric Patients
It increases myocardial contractility in pediatric patients with heart failure.
Atrial Fibrillation in Adults
It is indicated for the control of ventricular response rate in adult patients with chronic atrial fibrillation.

It is indicated for use in the management of acute myocardial infarction (AMI) in adults, for the lysis of intracoronary thrombi, the improvement of ventricular function, and the reduction of mortality associated with AMI, when administered by either the intravenous or the intracoronary route, as well as for the reduction of infarct size and congestive heart failure associated with AMI when administered by the intravenous route. Earlier administration of Streptokinase is correlated with greater clinical benefit.

  • Hypercalcemia/hypocalcemia
  • Renal impairment
  • Diseased SA node
  • Bradycardia
  • AV block
  • Restrictive cardiomyopathy
  • Constrictive pericarditis
  • Thyroid disease  (Hypothyroidism leads to delayed drug clearance, and hyperthyroidism does the opposite.)

  • The thrombolytic nature of streptokinase makes it contraindicated in patients with active internal bleeding, as it can worsen bleeding in some patients. It is also contraindicated in patients with severe uncontrolled hypertension, intracranial neoplasms, surgery within two months, recent stroke, and intraspinal surgery.
  • Streptokinase administered with extreme caution to those who have experienced recent trauma, coagulopathies or hematologic diseases, gastrointestinal bleeding, infective endocarditis, obstetric deliveries, diabetic hemorrhagic retinopathy, organ biopsies, or previous puncture of a non-compressible vessel. 
  • Streptokinase is a pregnancy Category C medication; the effects of streptokinase on a fetus are unknown, and pregnant patients should only receive streptokinase to prevent life-threatening injury

    It may be desirable to reduce the dose of or discontinue digoxin for 1 to 2 days prior to electrical cardioversion of atrial fibrillation to avoid the induction of ventricular arrhythmias, but physicians must consider the consequences of increasing the ventricular response if digoxin is decreased or withdrawn. If digitalis toxicity is suspected, elective cardioversion should be delayed. If it is not prudent to delay cardioversion, the lowest possible energy level should be selected to avoid provoking ventricular arrhythmias.

    The reported incidence of bleeding (major or minor) has varied widely depending on the indication, dose, route and duration of administration, and concomitant therapy.
    Allergic Reactions
    Mild or moderate allergic reactions may be managed with concomitant antihistamine and/or corticosteroid therapy. Severe allergic reactions require immediate discontinuation of Streptokinase, with adrenergic, antihistamine, and/or corticosteroid agents administered intravenously as required.
    Respiratory System
    There have been reports of respiratory depression in patients receiving Streptokinase. In some cases, it was not possible to determine whether the respiratory depression was associated with Streptokinase or was a symptom of the underlying process. If respiratory depression is associated with Streptokinase, the occurrence is believed to be rare.
