Muscarinic receptors:
Excite... Increase |
Excite or inhibit and increase Ca++ into the cell to initiate contraction of smooth muscle.
They increase secretion of exocrine glands. |
|
Alpha and beta adrenergic agonist.
|
Epinephrine
|
|
Norepinephrine receptor action
|
Alpha 2 adrenergic agonist
|
|
Albuterol acts on...
causing bronchodilation |
Beta2 agonist
|
|
Clonidine
|
Classification: Adrenergic alpha 2 agonist
Use: Centrally acting to decrease blood pressure. Used in alcohol withdrawal to reduce blood pressure response. Decreases release of norepinephrine in the brain and decreases the effect of the sympathetic nervous system. |
|
Beta 1 receptors act on...
|
cardiac. Stimulation increases heart rate and contractility
|
|
Beta 2 receptors are
|
in the bronchi. They cause dilation
|
|
Procainamide
Slows conduction velocity. Prolongs refractory period Ventricular |
Used To maintain NSR after conversion. Ventricular ectopic beats and Ventricular tachycardia
|
|
Quinidine
|
maintain NSR after conversion. Ventricular ectopic beats
Ventricular tachycardia |
|
Lidocaine
|
Use: Ventricular arrhythmias
|
|
Propranolol (Inderal)
a a s a p It does it all. |
Management of angina,
arrhythmias, supraventricular tachycardia, atrial fibrillation/flutter and PSVT. |
|
Esmolol
S A Atrial |
Management of supraventricular tachycardia,
atrial fibrillation/flutter |
|
Amiodarone
Ventricular |
IV use for Ventricular fibrillation/tachycardia.
PO use for recurrent ventricular tachycardia and to maintain NSR with atrial fibrillation/flutter. |
|
Diltiazem (Cardizem)use:
|
Use: IV for PSVT
|
|
Verapamil
|
PO for chronic suppression of PSVT and atrial fibrillation/flutter
|
|
Adenosine (Adenocard)
|
Use: Restore NSR after PSVT .
MOA: Reduces conduction of AV node. |
