fibrin specific drugs
Alteplase
Tenecteplase – Tenecteplase is a mutated form of alteplase with higher fibrin specificity and a longer half-life of elimination and is usually administered as a bolus infusion, whereas alteplase is usually administered as a 2-hour continuous infusion.

Streptokinase – Lower efficacy but lower bleeding risk
Recently utilised due to worldwide shortage of Alteplase/Tenecteplase.
contraindications of thrombolysis

prior intracranial haemorrhage
suspected aortic dissection
