Tryptophan

Research Papers that Mention the Interaction

Chronic co-administration of L-tryptophan with dihydrocodeine prevented the development of tolerance to the antitussive effects of dihydrocodeine.
Thus, it is concluded that L-tryptophan may antagonized the development of tolerance to the antitussive effects of dihydrocodeine.
