| Is indicated in the management of cardiac arrest. The chance of successful defibrillation is enhanced by administration of epinephrine and proper oxygenation. | Epinephrine |
| Produces an overall increase in heart rate and contractility, but newer agents have replaced it in most clinical settings. It is contraindicated in the routine treatment of cardiac arrest. | Isoproterenol (Isuprel) |
| Is indicated for significant hypotension in the absence of hypovolemia. Significant hypotension is present when systolic blood pressure is less than 90 mmHg with evidence of poor tissue perfusion, oliguria, or changes in mental status. | Dopamine (Intropin) |
| Reduce heart rate, blood pressure, myocardial contractility, and myocardial oxygen consumption which make them effective in the treatment of angina pectoris and hypertension. | Beta Blockers: Propranolol, Metaprolol, Atenolol, and Esmolol |
| Is the drug of choice for the suppression of ventricular ectopy, including ventricular tachycardia and ventricular flutter. Excessive doses can produce drowsiness, disorientation, decreased heart ability, and muscle twitching, and eventual seizures. | Lidocaine |
| Is used in the treatment of paroxysmal supraventricular tachycardia (PSVT), effective in terminating more than 90 % of episodes of PSVT in adults and infants. It is also useful in slowing ventricular response to atrial flutter and fibrillation. | Verapamil |
| Is the traditional drug of choice or the pain and anxiety associated with acute myocardial infarction. In high doses, may cause respiratory depression. It is a controlled substance and has a tendency for abuse and addiction. | Morphine Sulfate |
