Use
L-tryptophan, an essential aminoacid and precursor of serotonin,
was introduced into medicine in 1963 for the treatment of depression and sleep
disorders. Its effectiveness in these conditions has, however, never been
convincingly demonstrated. It is also widely used in dietary supplements,
parenteral nutrition preparations and dietary products for children with
phenylketonuria. In 1989, reports from the USA showed an association between the
consumption of L-tryptophan containing preparations and the development of
eosiniphilia-myalgia syndrome (EMS), a condition characterized by intense
eosinophilia, severe muscle and joint pain, swelling of the arms and legs, skin
rashes and possible fever. Some of the reported cases have been fatal. Since it is
not yet clear whether L-tryptophan itself or an unidentified contaminant is the
cause of the EMS, many drug regulatory authorities have suspended the marketing
authorization of products containing tryptophan pending further investigation,
whereas others have withdrawn these products or restricted their use.
