Key Psychotropic Medications to Know for Abnormal Psychology

Psychotropic medications play a crucial role in treating various mental health disorders. They help manage symptoms of conditions like depression, anxiety, and bipolar disorder by altering brain chemistry, improving overall well-being, and enhancing quality of life for many individuals.

1. Selective Serotonin Reuptake Inhibitors (SSRIs)

   • Primarily used to treat depression and anxiety disorders by increasing serotonin levels in the brain.
   • Common examples include fluoxetine (Prozac) and sertraline (Zoloft).
   • Generally well-tolerated with fewer side effects compared to older antidepressants.
   • May take several weeks to show full therapeutic effects.
   • Risk of withdrawal symptoms if discontinued abruptly.

2. Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)

   • Effective for depression, anxiety, and certain chronic pain conditions by affecting both serotonin and norepinephrine levels.
   • Examples include venlafaxine (Effexor) and duloxetine (Cymbalta).
   • Can cause side effects such as increased blood pressure and withdrawal symptoms.
   • May be more effective for certain patients who do not respond to SSRIs.
   • Dosage adjustments may be necessary based on individual response.

3. Tricyclic Antidepressants (TCAs)

   • Older class of antidepressants used for depression and some anxiety disorders.
   • Examples include amitriptyline and nortriptyline.
   • Work by blocking the reuptake of neurotransmitters like serotonin and norepinephrine.
   • Associated with more side effects, including weight gain, dry mouth, and sedation.
   • Overdose can be dangerous, requiring careful monitoring.

4. Monoamine Oxidase Inhibitors (MAOIs)

   • Used for depression, particularly atypical depression, by inhibiting the enzyme monoamine oxidase, which breaks down neurotransmitters.
   • Examples include phenelzine (Nardil) and tranylcypromine (Parnate).
   • Require dietary restrictions to avoid hypertensive crises from tyramine-rich foods.
   • Can interact with many medications, necessitating careful management.
   • Side effects may include dizziness, weight gain, and insomnia.

5. Benzodiazepines

   • Primarily prescribed for anxiety, insomnia, and seizure disorders due to their sedative effects.
   • Examples include diazepam (Valium) and lorazepam (Ativan).
   • Work by enhancing the effect of the neurotransmitter GABA, leading to calming effects.
   • Risk of dependence and withdrawal symptoms with long-term use.
   • Short-term use is generally recommended to avoid tolerance.

6. Antipsychotics (typical and atypical)

   • Used to treat psychotic disorders such as schizophrenia and bipolar disorder.
   • Typical antipsychotics (e.g., haloperidol) primarily target dopamine receptors.
   • Atypical antipsychotics (e.g., risperidone, olanzapine) affect both dopamine and serotonin receptors.
   • Side effects can include weight gain, metabolic syndrome, and extrapyramidal symptoms.
   • Monitoring for side effects is crucial, especially with long-term use.

7. Mood Stabilizers (e.g., Lithium)

   • Primarily used to treat bipolar disorder by stabilizing mood swings.
   • Lithium is the most well-known mood stabilizer, requiring regular blood level monitoring.
   • Other options include anticonvulsants like valproate and lamotrigine.
   • Side effects may include gastrointestinal issues, tremors, and thyroid dysfunction.
   • Effectiveness can vary, and dosage adjustments may be necessary.

8. Stimulants (for ADHD)

   • Commonly prescribed for Attention-Deficit/Hyperactivity Disorder (ADHD) to improve focus and attention.
   • Examples include methylphenidate (Ritalin) and amphetamine salts (Adderall).
   • Work by increasing levels of dopamine and norepinephrine in the brain.
   • Potential side effects include insomnia, decreased appetite, and increased heart rate.
   • Close monitoring is needed for potential misuse and cardiovascular effects.

9. Anxiolytics

   • Primarily used to treat anxiety disorders and panic attacks.
   • Benzodiazepines are a common class, but other options include buspirone.
   • Buspirone is non-sedating and has a lower risk of dependence compared to benzodiazepines.
   • Side effects can include dizziness, drowsiness, and cognitive impairment.
   • Treatment duration should be carefully managed to avoid dependence.

10. Hypnotics (sleep medications)

    • Used to treat insomnia and other sleep disorders.
    • Common examples include zolpidem (Ambien) and eszopiclone (Lunesta).
    • Work by enhancing GABA activity to promote sleep onset and maintenance.
    • Side effects may include drowsiness, dizziness, and potential for dependence.
    • Should be used for short-term management, with consideration of non-pharmacological approaches.
