Know how erection medications work. Currently there are four prescription drugs available for erection problems: Viagra, ****, **** and Yohimbine. They all essentially work the same way. Sexual arousal stimulates release of a compound, nitric oxide (NO), in the ****. Nitric oxide, in turn, triggers synthesis of cGMP, which relaxes the ****’ smooth muscle tissue, and allows extra blood to flow into the organ’s spongy central erectile tissues. Erection drugs enhance this smooth muscle relaxation, spurring greater blood flow into the ****.Depending on the medication, erection drugs are taken two to 36 hours before lovemaking, so the woman need not know you’re using a drug. These prescription drugs help men with ED caused by both physical illness and stress/anxiety problems. Most studies show that they produce erections in 75 percent of those who use them, with even greater effectiveness among men with only mild or occasional problems. They raise erection only with normal sexual stimulation. No walking around with an embarrassing bulge in your pants that signals you have taken a drug.
