Fildena 150 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate as its active ingredient, which belongs to the class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Like other doses of Fildena, the 150 mg variant works by inhibiting the action of PDE5, which allows for increased levels of cyclic guanosine monophosphate (cGMP) in the penile tissues. https://www.flatmeds.com/product/fildena-150-mg/
