Mechanism of action

Iloprost mimics the natural prostacyclin (PGI2), a potent vasodilator and antiplatelet agent. By activating prostacyclin receptors (IP receptors), it increases intracellular cAMP levels, leading to relaxation of vascular smooth muscle, improved blood flow, and reduced platelet activation. This mechanism is particularly beneficial in pulmonary hypertension where it reduces pulmonary vascular resistance and improves hemodynamics.
