A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes. Peripheral vasodilators are agents which act on the most distal parts of the vascular system i.e. the arterioles and venules. They dilate these distal blood vessels and lower the blood pressure, therefore makes it easier for the heart to pump blood through these peripheral blood vessels (and therefore whole the body). Peripheral vasodilators are used in the treatment of hypertension, acute myocardial infarction and heart failure.

Because of these actions, thrombolytic drugs are also called plasminogen activators and fibrinolytic drugs.. There are three major classes of fibrinolytic drugs: tissue plasminogen activator (tPA) , streptokinase (SK) , and urokinase (UK) .While drugs in these three classes all have the ability to effectively dissolve blood clots, they differ in their detailed mechanisms in ways that alter their selectivity for fibrin clots.The figure to the right illustrates the fibrinolytic mechanisms for tPA and SK.Derivatives of tPA are the most commonly used thrombolytic drugs, especially for coronary and cerebral vascular clots, because of their relative selectivity for activating fibrin-bound plasminogen.t is important to note that the efficacy of thrombolytic drugs depends on the age of the clot. Older clots have more fibrin cross-linking and are more compacted; therefore, older clots are more difficult to dissolve.
