Eriacta, containing the active ingredient sildenafil citrate, is a medication used to treat erectile dysfunction (ED) in men. It's essentially a brand of generic Viagra, offering the same primary function — enhancing blood flow to the penis to help achieve and maintain an erection. Sildenafil, the active component, works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5), which helps to relax the blood vessels in the penis and improve blood flow during sexual arousal. Eriacta is part of the group of medications known as PDE5 inhibitors, commonly used in the treatment of ED. https://www.imedix.com/drugs/eriacta
