Cilostazol
Uses of Cilostazol
Cilostazol is a phosphodiesterase III inhibitor used to manage symptoms of poor blood flow in the legs.
It is commonly used for:
- Intermittent claudication: Eases leg pain and cramping that occurs during walking due to reduced blood flow, helping improve walking distance.
- Peripheral vascular disease: Improves blood flow to the extremities, supporting overall mobility and quality of life.
- Circulatory symptoms: Helps reduce pain, tingling, numbness, and muscle cramps in the legs linked to poor circulation.

How Cilostazol works
- Cilostazol is a phosphodiesterase III inhibitor.
- It works by blocking an enzyme called phosphodiesterase III, which prevents the breakdown of a compound called cyclic adenosine monophosphate (cAMP) in blood vessels and platelets. This raises cAMP levels, which relaxes and widens blood vessels and reduces the clumping together of platelets.
- By improving blood flow and reducing platelet clumping, Cilostazol helps lower the risk of harmful blood clots forming and eases symptoms caused by poor circulation in the legs.
