What drug affects enzymatic decomposition of neurotransmitters?

Monoamine oxidase inhibitors (MAOIs) are a class of drugs that affect the enzymatic decomposition of neurotransmitters, particularly monoamines like serotonin, dopamine, and norepinephrine. By inhibiting the monoamine oxidase enzyme, these drugs prevent the breakdown of these neurotransmitters, thereby increasing their availability in the synaptic cleft and enhancing mood and emotional responses. MAOIs are commonly used in the treatment of depression and certain anxiety disorders.
