What mnemonic is used for the classification of antidepressants?

• A. A - SAD - SSRIs, Atypical, Derivative
• B. B - SNACK - SNRIs, NDRIs, Atypical, Clomipramine, Ketamine
• C. C - TREAT - TCA, Reuptake inhibitors, Efficacy, Antipsychotics, Tricyclics
• D. D - MOOD - Mood stabilizers, Opioids, Uplifters, Depressants

Answer: (B)

The mnemonic that is most commonly used for the classification of antidepressants is indeed associated with the term SNACK. This mnemonic effectively categorizes different types of antidepressants, which include:

• SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors),

• NDRIs (Norepinephrine-Dopamine Reuptake Inhibitors),

• Atypical antidepressants,

• Clomipramine (a tricyclic antidepressant), and

• Ketamine (which is increasingly recognized for its rapid antidepressant effects).

Each component of the mnemonic corresponds to a class of antidepressants, making it easier to remember them for clinical practice or exam preparation. This is particularly useful given the variations and nuances in antidepressant medications and their mechanisms of action.

The other options do not adequately represent the major classifications of antidepressants. For instance, the use of SAD or MOOD includes unrelated classes or inaccurately merges them, while TREAT does not accurately reflect the current understanding of antidepressant classifications. This highlights the importance of having a mnemonic that directly correlates with widely accepted antidepressant categories for better retention and recall in practical settings.
