Caverta 25 medicine is composed of Sildenafil Citrate. The medication is used for treating erectile dysfunction (ED), or impotence condition in men. Most cases of the impotence issues like ED are caused by physiological factors including diabetes, smoking, high blood pressure or surgery. The medicine comes in conventional tablet form for oral consumption, and it can help men to get an erection and keep it when they are sexually excited. The medicine works sensationally by expanding the arteries in the penile, so that blood flows into the penile, and constricting the veins leading out, so that more blood flows in and fewer flows out, which leads to a sustained erection. Caverta 25 does not treat erectile dysfunction, but it does treat it so that men might enjoy a normal sex life.
