nontricyclic antidepressant
Noun: A nontricyclic antidepressant is a class of antidepressant medication. These drugs are chemically distinct from tricyclic antidepressants (TCAs) and their primary mechanism of action does not involve the inhibition of monoamine oxidase (MAO) enzymes.
This term is used in medical and pharmacological contexts to categorize and discuss a specific group of antidepressant drugs based on their chemical structure and mechanism of action. It distinguishes them from the older classes of tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs).
- The doctor prescribed a nontricyclic antidepressant due to its potentially more favorable side-effect profile.
- SSRIs and SNRIs are common types of nontricyclic antidepressants.
- Research into new nontricyclic antidepressants focuses on different neurotransmitter systems.
The term is often used in comparative discussions about antidepressant efficacy, side effects, and pharmacological profiles. It serves as an umbrella term for several modern subclasses.
- Nontricyclic (adjective): Describing a drug that is not a tricyclic compound.
- The study compared tricyclic and nontricyclic treatments.
- Antidepressant (noun): A broader category of drugs used to treat depression.
- SSRI (Selective Serotonin Reuptake Inhibitor): A major subclass of nontricyclic antidepressants (e.g., fluoxetine, sertraline).
- SNRI (Serotonin-Norepinephrine Reuptake Inhibitor): Another major subclass (e.g., venlafaxine, duloxetine).
- Second-generation antidepressant (common clinical synonym)
- Atypical antidepressant (broader, less precise synonym)
This term has a single, specific meaning within psychiatry and pharmacology. It does not have general or figurative meanings.
- a class of antidepressant drugs that are not tricyclic drugs and do not act by inhibiting MAO
