STREPTASE INJECTION 1 500 000 IU POWDER FOR SOLUTION FOR INFUSION
Special warnings and precautions for use (continued)
• recent delivery, abortion
• diseases of the urinogenital tract with existing or potential sources of
bleeding (implanted bladder catheter)
• known septic thrombotic disease
• severe atherosclerotic vessel degeneration, cerebrovascular diseases
• cavernous pulmonary diseases, e.g. open tuberculosis
• mitral valve defects or atrial fibrillation
Because of the increased likelihood of resistance due to antistreptokinase
antibodies, repeat treatment with Streptase or streptokinase containing
products may not be effective if administered more than 5 days, particularly
between 5 days and 12 months after initial treatment.
Likewise, the therapeutic effect may be reduced in patients with recent
streptococcal infections such as streptococcal pharyngitis, acute rheumatic
fever and acute glomerulonephritis.
Infusion rate and corticosteroid prophylaxis
At the beginning of therapy, a fall in blood pressure, tachycardia or bradycardia
(in individual cases reaching as far as shock), are commonly observed.
Therefore, at the beginning of therapy the infusion should be performed
Corticosteroids can be administered prophylactically to reduce the likelihood
of infusion-related allergic reactions.
6. FURTHER INFORMATION
Pre-treatment with heparin or coumarin derivatives
If the patient is under active heparinization, it should be neutralised by the
administration of protamine sulphate before the start of the thrombolytic
therapy. The thrombin time should not be more than twice the normal control
value before thrombolytic therapy is started. In patients previously treated
with coumarin derivatives, the INR (International Normalized Ratio) must be
less than 1.3 before starting the streptokinase infusion.
Simultaneous treatment with acetylsalicylic acid
A positive, mutually reinforcing effect of acetylsalicyclic and streptokinase on
the life expectancy of patients with suspected myocardial infarction has been
observed in the ISIS-2 study. The administration of acetylsalicyclic acid should
commence prior to the streptokinase therapy and be continued for at least
Streptase is not indicated for restoration of patency of intravenous catheters.

1. WHAT STREPTASE INJECTION IS AND WHAT IT IS USED
Streptase Injection is a type of medicine called a fibrinolytic agent. It
contains a substance called streptokinase, which helps to dissolve blood

Special precautions for use, handling and disposal
To ensure that the contents of the vial are rapidly and completely dissolved,
5 ml of physiological saline should be injected into the Streptase-containing
vacuum vial and the residual vacuum abolished by briefly loosening the
needle from the syringe.
Upon reconstitution with physiological saline, a colourless to yellowish, clear
solution is obtained.
For administration with an infusion pump, physiological saline, Ringer-lactate
solution, 5 % glucose solution or 5 % fructose solution can be used as a
Once reconstituted with physiological saline, physico-chemical stability has
been demonstrated for 24 hours at +2 to +8 °C. From a microbiological point
of view and as Streptase contains no preservative, the reconstituted product
should be used immediately. If it is not administered immediately, storage
shall not exceed 24 hours at +2 to +8 °C.

everybody gets them.
You will not normally be asked to store your medicine as it will be given to
you by a doctor.
Very common side effects (affect more than 1 in 10 people)

disease) against streptokinase, the active ingredient of Streptase

After the injection has been prepared it may be kept in a fridge at 2 to
8 ºC for up to 24 hours.
Do not use this medicine after the expiry date shown on the carton and
Special care should be taken with Streptase Injection if:
• you have recently had severe bleeding in your stomach (e.g. an
• you have recently had a severe injury and have been resuscitated
• you are at risk of severe local bleeding, for example if you have
recently had an invasive operation, (e.g. where you have had a tube
inserted into your body)
• you have recently had a baby, miscarriage or abortion
• you have a disease of your urogenital tract (the parts of your
body used for excretion and reproduction)
• you have blood poisoning likely to cause clotting (septic thrombotic
• you have a disease of the arteries or a disease affecting the blood
vessels of your brain (cerebrovascular disease)
• you have tuberculosis (TB)

your body and so your doctor may choose to use a different type of
The following information is intended for medical or healthcare
Treatment of acute myocardial infarction within 12 hours of onset, with
persistent ST-segment elevation or recent left bundle-branch block.
Note: No statement on therapy outcome can be made for administration
beyond the time windows indicated above.
Posology and method of administration
The administration of Streptase may be intravenous or intracoronary.
Note: When thrombolytic therapy is necessary and a high antibody
concentration against streptokinase is present, or when recent streptokinase
therapy has been given (more than 5 days and less than one year previously),
homologous fibrinolytics should be used.
Systemic administration: A single dose of 1.5 million IU Streptase should be
infused intravenously over 60 minutes.
Local intracoronary administration: A bolus of 20,000 IU Streptase should be
followed by a maintenance infusion of 2,000 IU to 4,000 IU per minute over
30 to 90 minutes depending on the achievement of coronary artery patency.
The safety and efficacy of Streptase in children, infants and neonates have not
been established. The benefit of treatment has to be evaluated against the
potential risks, which may aggravate an acute life-threatening condition.
Treatment with aspirin (150 mg daily) for at least 4 weeks is recommended
for prophylaxis after streptokinase therapy for acute myocardial infarction.
The first dose should be given as soon as possible after the myocardial
Streptase must not be used in case of severe allergic reactions to the product.
Because of the increased risk of haemorrhage under thrombolytic therapy,
Streptase must not be given in the following situations:
• existing or recent internal haemorrhages
• all forms of reduced blood coagulability, in particular spontaneous fibrinolysis
and extensive clotting disorders
• recent cerebrovascular insults, intracranial or intraspinal surgery
• intracranial neoplasm
• recent head trauma
• arteriovenous malformation or aneurysm
• known neoplasm with risk of haemorrhage
• acute pancreatitis
• uncontrollable hypertension with systolic values above 200 mm Hg and/or
diastolic values above 100 mm Hg or hypertensive retinal changes grades
• recent implantation of a vessel prosthesis
• simultaneous treatment with oral anticoagulants (INR > 1.3)
• severe liver or kidney damage
• endocarditis or pericarditis. Isolated cases of pericarditis, misdiagnosed as
acute myocardial infarction and treated with Streptase, have resulted in
pericardial effusions including tamponade
• known haemorrhagic diathesis
• recent major operations (6th to 10th postoperative day, depending on the
severity of surgical intervention)
• invasive operations, e.g. recent organ biopsy, long-term (traumatic)
closed-chest cardiac massage
Special warnings and precautions for use
Individual benefit/risk assessment
The risk of therapy in case of life-threatening thromboembolic events, in
particular that of haemorrhages, must be weighed against the anticipated
benefit in cases such as:
• recent severe gastrointestinal bleeding, e.g. active peptic ulcer
• risk of severe local haemorrhage, e.g. in case of aortography by lumber route
• recent trauma and cardiopulmonary resuscitation
• invasive operations, e.g. recent intubation
• puncture of non-compressible vessels, intramuscular injections
