“…In theory, orgasm might be improved with medications that block 5HT-2 and 5HT-3 receptors, or enhance dopaminergic transmission. Indeed, the following agents have been studied as antidotes: the alpha 2 -adrenergic receptor antagonist, yohimbine; 33 the 5-HT 2 receptor antagonists, nefazodone 34 and cyproheptadine; 35 the 5-HT 3 receptor antagonist, granisetron; 36 the dopamine agonist, amantadine; 37 bupropion; 38,39 buspirone, 40 psychostimulants 41 and other agents, such as Ginkgo biloba and l-arginine (which increase NO) 42 and the phosphodiesterase type 5 inhibitors sildenafil, tadalafil and vardenafil. 30,43 Some agents with established antidepressant properties, such as bupropion, nefazodone and buspirone, may also be effective antidepressant augmentations, and improve sexual function indirectly via their effect on mood.…”
