|
cardio selective
|
|
Beta blockers used to treat angina
|
Inderol- propranolol
Tenormin- atenolol both are also used for HTN |
|
Beta blockers block the stimulation of _______ & ________ reducing myocardial oxygen demands
|
norepinephrine
epinephrine |
|
Contraindications for beta blockers are
|
bronchoconstrictive disorders
PVD diabetes |
|
Beta blockers should never be abruptly discontinued because they can cause
|
rebound angina
|
|

|
reduces the drugs efficiency
|
|
Calcium channel blockers used to treat angina
|
Cardizem- diltiazem
Procardia- nifedipine Calan- verapamil |
|
Calcium channel blockers may also be used to treat
|
HTN
dysrhythmias |
|
Angiotensin converting enzymes (ACE)
|

Trental- pentoxifylline
|
hemorrheolgic- improves micro-circulation and tissue perfusion by decreasing blood viscosity and improving flexibility of erythrocytes
