THERAPEUTIC CLASSIFICATION
Adjunct in the Management of Affective Disorders
ACTION AND CLINICAL PHARMACOLOGY
The rationale for the use of L-tryptophan in affective disorders is
based on clinical findings more
than 20 years ago, that L-tryptophan increases 5-HT (serotonin)
synthesis in the central nervous
system of humans. It has been demonstrated in clinical trials that
oral ingestion of L-tryptophan in
humans caused a significant increase in the level of the serotonin
metabolite,
5-hydroxyindoleacetic acid (5-HIAA), in the lumbar cerebrospinal
fluid, indicating an increased
turnover of serotonin in the CNS.
L-tryptophan is one of the eight essential amino acids. The minimum
daily requirements are said
to be 0.25 g for males and 0.15 g for females. It is present in the
hydrolysates of most proteins, the
average western diet containing between 1 and 3 grams per day. There
are two major metabolic
pathways for L-tryptophan, the first to serotonin, the second to
nicotinic acid.
Approximately 98% of dietary L-tryptophan is metabolized into
nicotinic acid and only a very
small amount is being metabolized to serotonin via the intermediary
stage of 5-hydroxy-
tryptophan (5-HTP). Tryptophan hydroxylase, the enzyme responsible for
this step, is the rate-
limiting enzyme for serotonin production and is normally only about
half-saturated. Central
nervous system serotonin is metabolized by monoamine oxidase to
5-HIAA.
