StreptokinaseThird Party Manufacturing in India

Streptokinase is a thrombolytic enzyme that works by activating the body's own fibrinolytic system. It forms a complex with plasminogen, which then converts additional plasminogen molecules into plasmin. Plasmin is a proteolytic enzyme that degrades fibrin, the structural protein that forms blood clots. This breaks down the thrombus and restores blood flow through the occluded vessel.

Unlike tissue plasminogen activator (t-PA), streptokinase does not require fibrin binding for activation, which gives it a longer duration of action lasting up to 24 hours. It acts on both recent and older clots, making it effective across a wider therapeutic window. However, because it is derived from bacterial proteins, the body can develop antibodies against it, limiting its use to a single course of treatment after four days from initial administration.

Therapeutic Uses

Streptokinase is prescribed for the treatment of:

• ST Elevation Myocardial Infarction (STEMI): Given intravenously as soon as possible after symptom onset when percutaneous coronary intervention is not available within 90-120 minutes
• Acute Massive Pulmonary Embolism: Used to dissolve life-threatening blood clots in the lungs
• Deep Vein Thrombosis (DVT): Helps restore blood flow in occluded deep veins
• Acute Arterial Thromboembolism: Treats acute blockages in peripheral arteries
• Occluded Arteriovenous Cannula: Clears blocked dialysis shunts and cannulas

Why Manufacturers Choose Streptokinase

Streptokinase remains one of the most widely used thrombolytic agents in developing countries due to its proven efficacy and cost-effectiveness compared to newer alternatives like t-PA. It is included in the WHO Essential Medicines List and continues to be a mainstay in acute cardiac care protocols across India, Africa, and Southeast Asia. The lyophilized powder formulation offers excellent stability and extended shelf life, making it suitable for distribution in regions with variable cold chain infrastructure.

This makes Streptokinase a consistently high-demand molecule for third party manufacturing in India, particularly for injectable manufacturing facilities with WHO-GMP certification serving both domestic hospital supply and export markets.
