Bupropion; Amineptine

Bupropion (Wellbutrin) is possibly less effective than nomifensine. Yet it's useful because it lacks the adverse effects on sexual function characteristic of the SSRIs. In some subjects, in fact, libido, arousal, and the intensity and duration of orgasm may actually increase. Bupropion mildly blocks the reuptake, but diminishes the release, of dopamine. This may account for reports of its diminished propensity to induce mania in the genetically susceptible. Its active metabolites block the reuptake of noradrenaline. Chewed as a gum, bupropion is good for giving up smoking. Scandalously, it isn't licensed and marketed in Europe.
Amineptine (Survector) is a clean-ish, (relatively) selective dopamine reuptake blocker. Higher doses promote dopamine release too. Amineptine is liable occasionally to cause spontaneous orgasms. It is a mild but pleasant psychostimulant and a fast-acting mood-brightener. Unlike other tricyclics, it doesn't impair libido or cognitive function. Unlike typical stimulants and other activating agents, it may actually improve sleep architecture.
Scandalously, amineptine isn't licensed and marketed in Britain and America. For it is feared it might have "abuse-potential".
