In some instances, such rapid cycling is believed to be not only exacerbated by but possibly caused by the use of conventional unimodal antidepressants such as tricyclics. For this reason, the routine use of such antidepressants should be considered ill-advised until patients have been shown to be resistant to lithium's acute antidepressant properties. Although lithium remains the initial treatment of choice for manic depression, a substantial majority of manic depressive patients prove to be lithium-resistant and a growing body of data suggests this refractory group is accompanied by a disproportionate amount of frequent mood swings.
