Terms in this set (32)

Classification: beta adrenergic antagonist, antianginal, antihypertensive
Action: binds with both beta1 and beta2 receptors and alpha1 receptors in vascular smooth muscle. Inhibits the strength of the hearts contractions, as well as heart rate. This results in a decrease in cardiac oxygen consumption.
Indications: ACS, SVT, sever hypertension
Adverse Effects: usually mild and transient; hypotensive symptoms, nausea/vomiting, bronchospasm, arrhythmia, bradycardia, AV block
Contraindication: hypotension, cardiogenic shock, acute pulmonary edema, heart failure, severe bradycardia, sick sinus syndrome, second or third degree heart block, asthma or acute bronchospasm, cocaine induced ACS, known sensitivity. Caution in pheochromocytoma, cerebrovascular disease or stroke, poorly controlled diabetes, with hepatic desease. Use caution at lowest effective dose in chronic lung disease.
Dose:
Cardiac: Note monitor blood pressure and heart rate closely during administration.
Adult: 10mg IV, IO over a 1-2min period. May repeat q 10min to a max of 150mg or give initial bolus and then follow with infusion at 2-8mg/min
Peds: 0.4-1mg/kg/hr to a max dose of 3mg/kg/hr
Severe hypertension: Adult-initial dose is 20mg IV, IO slow infusion over a 2min period. After the initial dose, blood pressure should be checked q 5min. repeat doses can be given at 10min intervals. The second dose should be 40mg IV, IO and subsequent doses should be 80mg IV,IO to a max total dose of 300mg. effect on BP typically noted within 5min from time of admin. Alternatively, may be administered via IV infusion at 2mg/min to a total max dose of 300mg.
Peds: 0.4-1mg/kg/hr IV, IO infusion with a maximum dose of 3mg/kg/hr
