Fildena 120 mg is similar to other PDE5 inhibitors like Viagra (Sildenafil), Cialis (Tadalafil), and Levitra (Vardenafil), but it has some distinct advantages. While Viagra typically lasts 4-6 hours, Fildena 120 mg offers comparable duration and effectiveness at a lower price point. Additionally, it works in much the same way as these other medications by increasing blood flow to the penis, improving sexual function.
