Which of the following drug(s) interact with Tryptophan?

Tryptophan is an essential amino acid that serves as a precursor to serotonin, a neurotransmitter involved in regulating mood, sleep, and appetite. When considering drug interactions with tryptophan, it is important to recognize that certain medications can influence its metabolism and effectiveness in the body.

Fluoxetine, a selective serotonin reuptake inhibitor (SSRI), can increase serotonin levels by inhibiting the reuptake of serotonin. This interaction may lead to elevated serotonin levels when combined with tryptophan, potentially increasing the risk of serotonin syndrome, a potentially life-threatening condition.

Monoamine oxidase inhibitors (MAOIs) also interact with tryptophan, as they inhibit the enzyme monoamine oxidase, which is responsible for breaking down serotonin. When MAOIs are taken with tryptophan, there is a risk of excessive serotonin accumulation, again raising concerns for serotonin syndrome.

Tricyclic antidepressants (TCAs) can similarly enhance serotonin effects, as many TCAs also influence neurotransmitter levels, including serotonin. Their interaction with tryptophan can lead to the same risks associated with the other medications mentioned.

Given these points, it is clear that all these drug classes interact with tryptophan, making the
