Retavase® (Reteplase) is indicated for use in the management of acute myocardial infarction (AMI) in adults for the improvement of ventricular function following AMI, the reduction of the incidence of congestive heart failure and the reduction of mortality associated with AMI. Treatment should be initiated as soon as possible after the onset of AMI symptoms (see CLINICAL PHARMACOLOGY).
DOSAGE AND ADMINISTRATION
Retavase® (Reteplase) is for intravenous administration only. Retavase® is administered as a 10 + 10 unit double-bolus injection. Two 10 unit bolus injections are required for a complete treatment. Each bolus is administered as an intravenous injection over 2 minutes. The second bolus is given 30 minutes after initiation of the first bolus injection. Each bolus injection should be given via an intravenous line in which no other medication is being simultaneously injected or infused. No other medication should be added to the injection solution containing Retavase®. There is no experience with patients receiving repeat courses of therapy with Retavase®. Heparin and Retavase® are incompatible when combined in solution. Do not administer heparin and Retavase® simultaneously in the same intravenous line.
If Retavase® is to be injected through an intravenous line containing heparin, a normal saline or 5% dextrose (D5W) solution should be flushed through the line prior to and following the Retavase injection.
Although the value of anticoagulants and antiplatelet drugs during and following administration of Retavase® has not been studied, heparin has been administered concomitantly in more than 99% of patients. Aspirin has been given either during and/or following heparin treatment. Studies assessing the safety and efficacy of Retavase® without adjunctive therapy with heparin and aspirin have not been performed.
Reconstitution – Retavase® Kit and Retavase® Half-Kit
Reconstitution should be carried out using the diluent and dispensing pin provided with Retavase®. It is important that Retavase® be reconstituted only with the supplied Sterile Water for Injection, USP (without preservatives). The reconstituted preparation results in a colorless solution containing Retavase® 1 unit/mL. Slight foaming upon reconstitution is not unusual; allowing the vial to stand undisturbed for several minutes is usually sufficient to allow dissipation of any large bubbles.
Because Retavase® contains no antibacterial preservatives, it should be reconstituted immediately before use. When reconstituted as directed, the solution may be used within 4 hours when stored at 2- 30°C (36-86°F). Prior to administration, the product should be visually inspected for particulate matter and discoloration.
Reconstitution Instructions – Retavase® Kit and Retavase® Half-Kit
