Fildena Professional is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Fildena Professional is a sublingual tablet formulation of sildenafil citrate, designed to help men achieve and maintain an erection during sexual stimulation. The active ingredient, sildenafil citrate, works by inhibiting the PDE5 enzyme. This leads to increased levels of cyclic guanosine monophosphate (cGMP), which causes relaxation of blood vessels in the penile region. The relaxed blood vessels allow for improved blood flow to the penis, resulting in the engorgement of penile tissues and the ability to achieve and sustain an erection when sexually aroused. https://www.genericday.com/fildena-professional.html
