ISOPROTERENOL Beta agonist used for symptomatic bradycardia when pacemaker is not
(Catecholamine) available and for transplanted heart. Also, used for refractory torsade de pointes
Bradycardia: Infuse 2-10 mcg/min; titrate to heart rate
Torsade: Titrate to increase rate until VT is suppressed
LIDOCAINE Suppresses ventricular arrhythmias by decreasing automaticity
(Antiarrhythmic) Prolongs conduction and refractoriness in ischemic tissue
Increases the fibrillation & decreases the defibrillation threshold
Does not affect myocardial contractility, B/P, or atrial rate.
Cardiac arrest: 1.0 - 1.5 mg/kg IV bolus; ½ dose repeated q 3-5 min;
Non-arrest: 1.0-1.5 mg/kg followed by IV drip of 1-4 mg/min. Second
bolus of 0.5 - 0.75 mg/kg q 5 - 10 min.
Max: of 3 mg/kg Bolus
The maintenance doses should be reduced by 50% in pt over 70 years old
or with liver dysfunction
METOPROLOL Beta blocking effects used in all MI’s and unstable angina’s
