Nitrodilators
Nitroglycerin |
Isosorbide dinitrate |
Amyl nitrite (Isopentyl nitrite) |
Sublingual in emergencies with rapid action but very short half life. |
Better oral bioavailability and longer half life (1hr) |
Inhaled volatile liq. |
Photosensitive and tolerance is possiable |
|
Not recommended due to flushing. |
Adverse effects:
1. Vasodilation: headache, hypotension
2. Tolerance
3. Large doses= methemoglobinemia & cyanosis
|
|
CCB
Dihydropyridines |
Aralkyl amine deri. |
Benzothiazepine |
-Nifedipine- |
-Verapamil- |
-Diltiazem- |
the prototype; potent VD |
ttt of angina, arrythmia, HTN |
Less potent for arrythmia |
for HTN, angina. |
chiral molecule with levorotatory as most potent form |
for variant angina |
NOT for arrythmia due to no or little effect on heart nodes. |
NO2 (nitro gp) essential for activity. |
Amlodipine |
Longer t1/2 but lesser -ve inotropy due to more vascular selectivity. |
-Felodipine, Nicardipine- |
Block L-type/slow Ca channels for coronary VD or spasm relief.
Antithrombotic & anti-platelet
Aspirin |
Dipyridamole |
Thienopyridine deriv. |
|
Non-nitrate |
Purine-receptor blockers on platlets to stop aggregation activation |
|
Potentiates PGI2 (prostacyclin) |
-Ticlopidine- |
|
Essentially, increases presence of the VD adenosine. |
SE: neutropenia |
|
prophylaxis for chronic angina pectoris. |
-Clopidogrel- |
|
|
reduced neutropenia |
K channel agonist
-Nicorandil- |
Chemical class: Nicotinamide nitrate ester |
Direct vasodilator for both normal and diseased coronary arteries. |
