Nardil and Parnate belong to which class of antidepressants?

Explanation:
Monoamine oxidase inhibitors. Nardil (phenelzine) and Parnate (tranylcypromine) work by blocking the enzyme monoamine oxidase, which normally breaks down neurotransmitters such as serotonin, norepinephrine, and dopamine. When this enzyme is inhibited, these transmitters accumulate in the brain, helping to lift mood in many cases. This mechanism is different from SSRIs and SNRIs, which increase neurotransmitter levels by preventing reuptake, and from TCAs, which affect reuptake and other receptor systems. Because MAOIs raise multiple monoamines, they carry dietary restrictions (tyramine risk) and potential dangerous interactions with other antidepressants, underscoring why they’re classified separately from the other classes.
