Caverta, containing sildenafil citrate, is a medication used for treating erectile dysfunction (ED) in men. Similar to Viagra, it works by enhancing blood flow to the penis, aiding in achieving and maintaining an erection. The active ingredient, sildenafil, functions by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for regulating blood flow in the penile area. https://www.imedix.com/drugs/caverta
