Serotonin Reuptake Inhibitors (SSRIs): These medications block the reuptake of serotonin in the brain, increasing its availability and improving mood.
Monoamine Oxidase Inhibitors (MAOIs): MAOIs work by inhibiting an enzyme called monoamine oxidase, which breaks down neurotransmitters like serotonin. By blocking this enzyme, MAOIs help maintain higher levels of these neurotransmitters in the brain.
Tricyclic Antidepressants (TCAs): TCAs work by blocking the reuptake of both serotonin and norepinephrine, leading to increased levels of these neurotransmitters in the brain.
