oxygen | should be given to all patient with acute chest pain. |
Epinephrine | indicated in the management of cardiac arrest |
Isoproterenol(Isuprel) | produces an overall increase in heart rate and myocardial contractility. It is contraindicated in the routine treatment of cardiac arrest. |
Dopamine(Intropin) | indicated for significant hypotension in the absence of hypovolemia.It should be used at the lowest dose that produce adequate perfusion of vital organs. |
Beta Blockers: Propranolol,Metoprolol,Atenolol,and Esmolol. | reduce heart rate ,blood pressure,myocardial contractility,and myocardial oxygen consumption which make them effective in treatment of angina pectoris and hypertension.adverse effect are hypotension,congestive heart failure and broncho-spasm. |
Lidocaine | drug of choice for the suppression of ventricular ectopy,including ventricular tachycardia and ventricular flutter. Excessive doses can produce neurological changes, myocardial depression, and circulatory depression. |
Verapamil | used in the treatment of paroxysmal supraventricular tachycardia (PSVT), effective in terminating more than 90% of episodes of PVST in adults and infants. |
Digitalis | the force of cardiac contraction as well as cardiac output.Patients require constant monitoring for signs and symptoms of toxicity such as: yellow vision, nausea, vomiting, and drowsiness. |
Morphine Sulfate | the traditional drug of choice for the pain and anxiety associated with acute myocardial infarction., morphine sulfate may cause respiratory depression. It is a controlled substance and has a tendency for abuse and addiction. |
