Mental Health Medications Overview for Pharmacy Techs

Common psychiatric drug classes relevant to the PTCE.

March 14, 2026

Why Mental Health Medications Are Important

Psychiatric medications are among the most commonly dispensed drug categories. The PTCE Medications domain expects you to recognize major classes, common examples, and key facts about these widely prescribed drugs.

SSRIs

Selective serotonin reuptake inhibitors are commonly prescribed for depression and anxiety. Common examples include sertraline (Zoloft), fluoxetine (Prozac), escitalopram (Lexapro), and paroxetine (Paxil). Patients starting SSRIs should be aware that the full therapeutic effect may take several weeks to develop.

SNRIs

Serotonin-norepinephrine reuptake inhibitors include venlafaxine (Effexor) and duloxetine (Cymbalta). These are used for depression, anxiety, and some pain conditions. Like SSRIs, they may take time to reach full effectiveness.

Benzodiazepines

Alprazolam (Xanax), lorazepam (Ativan), and diazepam (Valium) are Schedule IV controlled substances used for anxiety and related conditions. They carry risks of dependence with long-term use, which is why they are controlled substances.

Mood Stabilizers

Lithium is a well-known mood stabilizer that requires monitoring. It has a narrow therapeutic range, meaning the difference between an effective dose and a potentially harmful dose is relatively small.

Antipsychotics

Medications like quetiapine (Seroquel), risperidone (Risperdal), and aripiprazole (Abilify) are used for various psychiatric conditions. Some are also used in lower doses for sleep or as adjunct treatments for depression.

Study Tips

Focus on recognizing which drug class each medication belongs to, common brand/generic pairs, and any notable handling or controlled substance classification. For the PTCE, broad familiarity across classes is more important than deep knowledge of any single medication.
