Tenecteplase (TNKase) is given by bolus injection. Tissue plasminogen activator (tPA) must be infused over 90 minutes. Because tenecteplase (TNKase) is given by bolus injection, an infusion pump is not required. Although the patient should be monitored, tenecteplase (TNKase) does not require a prolonged infusion time.
