Tadarise 40 Mg belongs to a class of medications called phosphodiesterase type 5 inhibitors (PDE5 inhibitors), primarily employed for treating erectile dysfunction (ED). By inhibiting the enzyme PDE5, Tadarise enhances the dilation of blood vessels, facilitating penile erection. However, its vasodilatory effects also hold promise in other conditions, such as pulmonary arterial hypertension.
