What is APO-TRYPTOPHAN used for?

L-Tryptophan is used as a valuable adjunct to antidepressant drug treatment in the management of patients suffering from depressive disorders (bipolar affective disorders). An adjunctive effect has been observed in some cases when L-tryptophan is given in combination with lithium in bipolar patients with mania or depression for whom lithium alone or in combination with neuroleptics or tricyclics has been shown little or no effect. Clinical observations suggest the possibility that the combination of lithium and L-tryptophan may reduce the need for the higher, more toxic doses of lithium necessary to control acute mania.

Authorized indication as written in the Health Canada product monograph. For healthcare professionals and licensed purchasers; this is not medical advice.
