tPA, Activase
Alteplase Recombinant (tPA) Class
Thrombolytic
Alteplase Recombinant (tPA, Activase) Description
Recombinant DNA- derived from human tPA hormone, tPA promotes thrombolysis by forming plasmin. Plasmin in turn degrades fibrin and fibrinogen and ultimately the clot.

Recent major surgery, cerebral vascular disease, recent GI or GU bleeding, recent trauma, hypertension, patient > 75 years, current oral anticoagulants, or hemmorrhagic ophthalmic conditions

Class
Anticoagulant
Heparin
Description
Rapid onset anticoagulant, enhancing the effects of antithrombin III and blocking the conversion of prothrombin to thrombin and fibrinogen to fibrin
Heparin
Indication
To prevent thrombus formation in acute MI

Norepinephrine Bitartrate
Norepinephrine Bitartrate (Levaphed) Class
Sympathomimetic, vasopressor
Norepinephrine Bitartrate (Levaphed) Description
Potent alpha agonist resulting in intense peripheral vasoconstriction, positive chronotropic and increased inotropic effects ( from 10% beta effect) with increased cardiac output. Alpha-adrenergic activity resulting in peripheral vasoconstriction and beta adrenergic activity leading to inotropic stimulation of the heart and coronary artery vasodilation

Bradycardia, hypertension, dysrhythmias, chest pain, peripheral cyanosis, tissue necrosis from extravasation
Norepinephrine Bitartrate (Levaphed) Dose/Route
Dilute 8 mg in 500mL of D5W or 4 mg in 250mL D5W (16 ug/mL). Infuse by IV piggy-back at 0.1-0.5 ug/kg/min tritrated to response (average dose for 70kg patient 7-35 ug/min)
Norepinephrine Bitartrate (Levaphed) Pedi Dose/Route
Begin at 0.1-2 ug/kg/min IV infusion, adjust rate to achieve desired change in blood pressure and systemic perfusion. Tritrated to patient response.
