Antidepressants that activate dopaminergic (bupropion (Wellbutrin), venlafaxine(Effexor)), central noradrenic receptors (mirtazepine, bupropion, venlafaxine) and 5-hydroxytriptamine (5-HT) A1 and 2C receptors (nefazodone (Serzone), mirtazepine) may augment sexual response.

"Traditional blood pressure lowering medications, like reserpine and guanethidine, often cause sexual dysfunction in men, along with dizziness and depression, and for this reason many doctors have moved away from them. Beta-blockers marketed under the names Inderal, Lopressor, Corgard, Blocadren, and Tenormin have fewer side effects, but many people who take them still complain of sexual dysfunction. In recent years calcium channel blockers, marketed as Adalat, Procardia, Calan, Isoptin, Verelan, Cardizem, Dilacor XR, and Tiazac have become more popular, in part because they have less effect on sexual function."
