์์ฉ ๊ธฐ์ : Propentofylline acts primarily via the **inhibition of phosphodiesterase (PDE)**, which increases intracellular cAMP levels. * **Vasodilation:** Increases blood flow to the heart, skeletal muscle, and central nervous system (CNS). * **Cardiac effects:** Exhibits positive inotropic (increased contractility) and chronotropic (increased heart rate) effects, alongside mild antiarrhythmic properties. * **Respiratory effects:** Acts as a bronchodilator. * **Hematologic effects:** Inhibits platelet aggregation and reduces peripheral vascular resistance.
