Intermittent Claudication: Intermittent claudication is a symptom of peripheral artery disease (PAD) characterized by pain or cramping in the legs during physical activity. Pentoxifylline is often prescribed to relieve symptoms and improve exercise tolerance in individuals with intermittent claudication by increasing blood flow to the legs and reducing muscle ischemia.

Mechanism of Action


Pentoxifylline works by reducing blood viscosity and improving red blood cell flexibility. It alters the rheological properties of blood, which is crucial for enhancing microcirculation, particularly in tissues affected by ischemia. The drug inhibits phosphodiesterase, leading to increased levels of cyclic AMP within cells. This mechanism helps dilate blood vessels and promotes better blood flow, which is particularly beneficial for patients suffering from peripheral arterial diseases.


Active pharmaceutical ingredients (APIs) are crucial components in the formulation of medications, directly influencing their therapeutic effects. A notable category within APIs is light-sensitive active pharmaceutical ingredients, which require special considerations during manufacturing, storage, and administration due to their susceptibility to degradation upon exposure to light.
