“…Clinical studies have shown antidepressant effects of dopamine agonists including piribedil (Post et al, 1978) and bromocriptine (Colonna et al, 1979;Nordin et al, 1981;Silverstone, 1984), and dopamine uptake inhibitors such as nominfesine (Vanscheyen et al, 1977), bupropion (Feighner et al, 1984), minaprine (Amsterdam et al, 1989), and amineptine (Rampello et al, 1991). In contrast, dopamine receptor antagonists enhance the depression-like symptoms (Mann and Kapur, 1995).…”
