![]() During the intravenous administration of metoprolol tartrate, blood pressure, heart rate, and electrocardiogram should be carefully monitored. Treatment in this early phase should begin with the intravenous administration of three bolus injections of 5 mg of metoprolol tartrate each the injections should be given at approximately 2-minute intervals. Such treatment should be initiated in a coronary care or similar unit immediately after the patient’s hemodynamic condition has stabilized. Supraventricular tachycardias(PAT, A-fib/flutter): 5 to 15 mg (usually 5 mg) over 2.5 min at 7.5min intervals-usually a high response rate.Įarly Treatment: During the early phase of definite or suspected acute myocardial infarction, treatment with metoprolol tartrate can be initiated as soon as possible after the patient’s arrival in the hospital. ![]() May switch to oral dosing (50 to 100mg po q6h) after IV bolus therapy. Unstable angina: 5 mg IV bolus x3 q2min f/b 2 to 5 mg hourly titrated to min HR of 55 to 60 BPM or min systolic BP of 80. In patients who tolerate full 15 mg dose, oral lopressor 50mg po q6h should be started 15 min after last IV dose x 48 hours. Post MI (early tx): 5 mg IV bolus x 3 doses q2 minutes. IV therapy permits rapid control of HR and contractility. Lopressor may be given by IV bolus (HR, BP, and EKG should be carefully monitored). Oral to IV conversion (2.5 to 1) : eg 50mg oral=20mg IV (equivalent beta-blockade). The infusion times were formulated to mimic the onset of an oral formulation. ![]() The dilutions listed are conservative guidelines that can be used in non-acute conditions.
