Types of angina

(2)-Varient /Prinzmetal/Vasopastic angina
Attacks occur at rest during sleep and are unpredictables..
(3)-Unstable angina -Increase in duration and severity of attacks ,which may occur even during rest ..
Mostly due to rupture of an antheromatous plaque attacking platelets.
Classification of drugs -
.Terminate attacks -Nitrates
.Used for chronic prophylaxis -other drugs
(1)-Nitrates
Nitrates dilate the veins more than artries, peripheral pooling of blood and decreased venus return (preload on heart reduced) end diastolic size and pressure reduced.
Short acting nitrates -Glyceryl trinitrates
Long acting nitrates -Isosorbide
(2)-Beta blockers
Reduced cardiac work and oxygen consumption as a consequences decrease in heart rate..
EX -propanalol, Metoprolol
(3)-Calcium channel blocker
Interfere with calcium movement into the cell and slower the movement of calcium in the cell..
Ex-Verapamil, Diltiazem ,Amlodipine
(4)-Potassium channel openers
Regulate the movement of ion across the cell membrane ..
Ex-Nicorandil
(5)Other antianginal drugs-Trimetazadine, Ranolazine ,Dipyrmidole
