Tadalafil is active ingredient of this product.<br />Ceebis is in a class of medications known as PDE-5 inhibitors, which are used to treat cases of male impotence.<br />Under normal circumstances, when a man is sexually stimulated, the penis fills up with blood. When erectile dysfunction occurs, enough blood does not flow to cause an erection. Ceebis relaxes the penile blood vessels when a man is sexually stimulated. This allows blood flow into the penis, resulting in an erection.<br />The erection subsides after sex, just as it is supposed to in normal conditions. Please understand that Ceebis is not a hormone or aphrodisiac, it works only when a man is sexually stimulated.
