nontricyclic drug
Học thuậtThân thiện
Definition
- Noun:
- A class of antidepressant drugs: A nontricyclic drug is a type of medication used to treat depression. It is specifically defined by not being a tricyclic antidepressant (TCA) and not functioning by inhibiting the enzyme monoamine oxidase (MAO).
Usage
- The term is used in pharmacology and psychiatry to categorize and distinguish newer or alternative antidepressant medications from the two older major classes: tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs).
- It is a technical, compound noun. In general medical communication, the specific drug class name (e.g., SSRI, SNRI) is more common than the umbrella term "nontricyclic drug."
Examples
- Noun:
- The doctor prescribed a nontricyclic drug because the patient experienced side effects from traditional tricyclic medications.
- Selective serotonin reuptake inhibitors (SSRIs) are a prominent subclass of nontricyclic antidepressant drugs.
Advanced Usage
- The term is primarily used in formal, comparative, or historical contexts within medical literature to discuss the evolution of antidepressant therapies.
- "Nontricyclic, non-MAOI antidepressant": A more precise but less common phrasing emphasizing the dual distinction from both older drug classes.
Variants and Related Words
- Nontricyclic antidepressant (noun): A full and more common variant of the term.
- SSRI (Selective Serotonin Reuptake Inhibitor) (noun): A common subclass of nontricyclic drugs (e.g., fluoxetine, sertraline).
- SNRI (Serotonin-Norepinephrine Reuptake Inhibitor) (noun): Another common subclass of nontricyclic drugs (e.g., venlafaxine, duloxetine).
- Tricyclic antidepressant (TCA) (noun): The older class of drugs from which nontricyclics are distinguished (e.g., amitriptyline, imipramine).
- MAOI (Monoamine Oxidase Inhibitor) (noun): The other older class of antidepressants that nontricyclics are also distinct from (e.g., phenelzine).
Synonyms
- Atypical antidepressant (noun): A broader, sometimes overlapping term for antidepressants that do not fit the classic TCA or MAOI categories. Not all atypical antidepressants are strictly nontricyclic, but many are.
- Second-generation antidepressant (noun): A historical term often encompassing nontricyclic drugs that followed the first-generation TCAs and MAOIs.
Related Phrases
- Non-tricyclic agent: An alternative phrasing with the same meaning, where "agent" is synonymous with "drug" in a medical context.
