Action
Description: Reteplase is a nonglycosylated plasminogen activator (tPA) and proteolytic enzyme produced using E. coli recombinant DNA. It that converts plasminogen to plasmin, which in turn degrades the fibrin, thereby exerting its thrombolytic action.
Onset: Thrombolysis: 30-90 minutes. Pharmacokinetics: Excretion: Via faeces and urine. Elimination half-life: 13-16 minutes. Initial half-life: 14 minutes. Terminal half-life: Approx 1.6 hours (patients with MI). |
Storage
Store between 2-25°C. Protect from light.
