Carctiovascular agents include cardiotonic drugs (Digitalis glycosides), vasodilators (esters of nitrous and nitric acid and some alkaloids, e.g. nicotinylalcohol, dipyridazole), hypotensive drugs that modify cardiac rhythm (Rauwolfia alkaloids, Veratrum alkaloids and some other compounds like guanethidine, methyldopa, pargyline),  antihypercholesterolemic drugs (e.g. clofibrate, dextrothyroxine) and sclerosing agents (e.g. invert sugar, dextrose, ethyl alcohol, iron salts, urea, quinine, soaps,etc
