S-Kinase Powder for Injection contains Streptokinase
S-Kinase Powder for Injection side effects
The following adverse reactions are based on experience from clinical trials and on post marketing experience of Streptokinase.
General disorders:
- Common: Headache and back pain, muscle pain (including myalgia), chills and/or fever as well as asthenia/malaise.
Haemorrhage and bleeding:
- Common: Haemorrhages at invaded or disturbed sites, including the injection site, and ecchymoses. Gastrointestinal or genitourinary bleedings (including aggravation of menstrual bleeding), epistaxis.
- Uncommon: Intracranial haemorrhages with their complications and possible fatal outcome, retinal haemorrhages, severe haemorrhages (also with fatal outcome) including liver haemorrhages, retroperitoneal bleedings, splenic rupture. Blood transfusions are rarely required.
Immune system disorders:
- Very common: Development of antistreptokinase antibodies
- Common: Allergic-anaphylactic reactions such as rash, flushing, itching, urticaria, angioneurotic oedema, minor breathing difficulty, periorbital swelling, bronchospasm or hypotension.
Nervous system disorders:
- Rare: Neurologic symptoms (e.g., dizziness, confusion, paralysis, hemiparesis, agitation or convulsion) in the context of cerebral haemorrhages or cardiovascular disorders with hypoperfusion of the brain.
Cardiac complication and vascular disorders:
- Very common: Hypotension, heart rate and rhythm disorders, angina pectoris.
- Common: Recurrent ischaemia, heart failure, reinfarction, cardiogenic shock, pericarditis, pulmonary oedema.
- Uncommon: Cardiac arrest (leading to respiratory arrest), mitral insufficiency, pericardial effusion, cardiac tamponade, myocardial rupture, pulmonary or distal embolism.
Respiratory disorders:
- Very rare: Non-cardiogenic pulmonary oedema after intracoronary thrombolytic therapy in patients with extensive myocardial infarction.
Gastrointestinal disorders:
- Common: Nausea, diarrhoea, epigastric pain and vomiting.
Because of the increased likelihood of resistance, due to antistreptokinase antibodies, retreatment with Streptokinase or Streptokinase-containing products may not be effective if administered between five days and twelve months of prior Streptokinase administration or Streptococcal infections, such as Streptococcal pharyngitis, acute rheumatic fever or acute glomerulonephritis secondary to a Streptococcal infection.
In principle, no thrombolytic treatment should be commenced before the 10th postoperative day. However, in cases of pulmonary embolism, the indication for earlier treatment may be very strong and after careful consideration of all the risks, Streptokinase may be given before the tenth postoperative day. The danger of bleeding from the operative area must, of course, be taken into account.The danger of haemorrhage is increased by simultaneous or previous treatment with anticoagulants (e.g., Heparin) or substances which inhibit platelet formation or function. If the patient is under active heparinisation, it should be neutralised by the administration of protamine sulphate before the start of thrombolytic therapy.
Repeated Administration: After administration of Streptokinase, the titre of antistreptokinase antibodies begins to rise after approximately one week, reaching a peak at 2 to 3 weeks and remains elevated for 8 to 12 months. Because of the increased likelihood of resistance, Streptokinase may not be effective if given during this period.
There is an increased risk of haemorrhage in patients simultaneously or previously receiving anticoagulants (such as Heparin or Coumarin derivatives) or drugs which inhibit platelet formation or function (e.g., Platelet aggregation inhibitors, Dextrans, Phenylbutazone, Dipyridamole, Non-steroidal anti-inflammatory drugs). The effect of Heparin can be neutralized rapidly by administration of Protamine Sulphate. The Thrombin time (TT) should not be more than twice the normal control value before thrombolytic therapy is started. In the case of prior treatment with coumarin derivatives, the International Normalized Ratio (INR) must be less than 1.3 before starting Streptokinase infusion.
Combination of Streptokinase with Aspirin for treatment of Myocardial infarction: Study showed a significant benefit to patients treated with these two agents after acute myocardial infarction. Mortality (both short and longer term) was reduced in these patients to a greater extent than in those treated with either agent alone.
Unless contraindicated, the concomitant use of Acetylsalicylic acid (ASA, Aspirin), starting prior to Streptokinase infusion and continued for one month thereafter may be instituted at the discretion of the physician. The benefit of combination therapy should therefore be weighed against the risk of increased haemorrhage.
Anticoagulation treatment following Streptokinase: Following high dose (1.5 million IU), short term treatment with Streptokinase, for acute myocardial infarction, the use of subsequent anticoagulant treatment has not yet been shown to be of unequivocal benefit. Therefore, in this situation, the use of anticoagulants should be decided by the physician.
Pregnancy category C. It is not known whether Streptokinase is excreted in the breast milk, nor whether it has harmful effects on the newborn. In the absence of further information, it is recommended that breast-feeding be discontinued in women who are to receive Streptokinase.
As thrombolytic therapy increases the risk of bleeding, Streptokinase, administered either systemically or locally, is contraindicated in the following situations:
Existing or recent haemorrhage and haemorrhagic diathesis (with the exception of consumption coagulopathy) Potential for internal bleeding (e.g., peptic ulcer, ulcerative colitis, diverticulitis or visceral tumours) All forms of reduced blood coagulability, in particular spontaneous fibrinolysis and extensive clotting disorders.
Recent (within 2 months) cerebrovascular accident, recent (within 10 days) facial or head trauma, intracranial or intraspinal surgery, known intracranial neoplasm and all known neoplasms with risk of haemorrhage
Invasive operations, e.g., recent organ biopsy, invasive diagnostic procedure, recent implantation of a vessel prosthesis, long-term traumatic closed-chest massage or other recent surgery (until the 6th to 10th post operative day, depending on the severity of surgical intervention)
Arteriovenous malformation or aneurysm: Haemorrhagic diathesis including thrombocytopenia or pronounced hepatic or renal dysfunction
Severe uncontrolled hypertension (systolic BP > 200 mm Hg, diastolic BP > 100 mm Hg), or hypertensive retinal changes grades III/IV), hypertonic fundus
Severe liver or kidney damage: Simultaneous treatment with oral anticoagulants (International Normalized Ratio (INR) >1.3)
Endocarditis or pericarditis (Immediately after streptococcal infections which have produced a high antiStreptokinase titre (acute rheumatic fever, acute glomerulo-nephritis, etc.). More than 5 days and less than 12 months since previous Streptokinase therapy.
Pediatric use: Safety & effectiveness in children have not been established.
