action

of

 dilitazem

inhibts influx of calcium ions across cell membrane

affects AV node conduction

prolongs sinus cycle

decreases bp

typically used for rate control

used only 4 narrow qrs

ankle edma gingival hyperplasia, bradycardia

decreased myocardial contractility, hypotention cardiac arrest

action

of

metoprolol

side decreases vascular resistanced

bradycardia

reduced CO

AV block

rebound cardiac excitation

heart failure

hypotention

RENALY CLEARED

IV NOT STOCKED AT UIHC

alpha and beta blocker

affects rate and bp

intermittent iv push dose as needed

for neuro storms

scheduled iv doses q6-8 hrs

old drug

used for anxiety /HA

not 1:1 converstion

--antiarrhythmis class 3

-block na channel & slows intraventicular conduction

-blocks beta adrenergic receptors and calcium channels witch impeads AV node conductions and slows hr

-blocks k+ channels and prolongs atrial and venticular repolarization

-arrhythmias CHF

-peripheral neuropathy, tremors

-lung inflamation fibrosis

-hepatitia cirrhosis

-photosentivity bluish tent to skin

action NITROGLYCERN

hypotention  ^hr flushing

nausea vomiting

headache nausea

action MILRINONE

phosphodienstrase inhibitor

increases contractility

vasodilates by increasing intracellular cyclic adenosine monophosate

major sde effect is ventricular arrhythmias

Beta adrenergic agent

inotrope of choice in septic shock
