Anxiolytics
- Used to treat anxiety disorders
- Benzodiazepines (BZDs) are effective for short-term anxiety relief, but have risk of dependence and withdrawal symptoms
- Examples of BZDs include alprazolam (Xanax) and clonazepam (Klonopin)
- Non-benzodiazepines are safer than BZDs, with less risk of dependence
- Examples of non-benzodiazepines include buspirone (Buspar) and hydroxyzine (Vistaril)
- Antidepressants, especially selective serotonin reuptake inhibitors (SSRIs), have anxiolytic properties
- Examples of SSRIs include fluoxetine (Prozac) and sertraline (Zoloft)
Antipsychotics
- Used to treat psychotic symptoms, such as hallucinations and delusions
- Typical antipsychotics are an older generation, with more side effects
- Examples of typical antipsychotics include haloperidol (Haldol) and chlorpromazine (Thorazine)
- Atypical antipsychotics are a newer generation, with fewer side effects
- Examples of atypical antipsychotics include risperidone (Risperdal), olanzapine (Zyprexa), and quetiapine (Seroquel)
- Mechanism of action: block dopamine receptors in the brain
- Side effects include extrapyramidal symptoms (EPS) and metabolic changes
Mood Stabilizers
- Used to treat mood disorders, such as bipolar disorder
- Lithium is the most commonly used mood stabilizer, effective for manic episodes
- Anticonvulsants, such as valproate (Depakote) and lamotrigine (Lamictal), have mood-stabilizing properties
- Some atypical antipsychotics, such as olanzapine (Zyprexa) and quetiapine (Seroquel), also have mood-stabilizing properties
- Mechanism of action: regulate neurotransmitters and ion channels in the brain
Antidepressants
- Used to treat depressive disorders
- Selective serotonin reuptake inhibitors (SSRIs) are the most commonly used antidepressants
- Examples of SSRIs include fluoxetine (Prozac), sertraline (Zoloft), and paroxetine (Paxil)
- Serotonin-norepinephrine reuptake inhibitors (SNRIs) are effective for depression and pain
- Examples of SNRIs include venlafaxine (Effexor) and duloxetine (Cymbalta)
- Tricyclic antidepressants (TCAs) are an older generation, with more side effects
- Examples of TCAs include amitriptyline (Elavil) and imipramine (Tofranil)
- Mechanism of action: increase neurotransmitters, such as serotonin and norepinephrine, in the brain
Substance Abuse Treatment
- Medications used to treat substance use disorders
- For opioid use disorder: methadone is used for maintenance treatment, and buprenorphine is a partial opioid agonist
- For alcohol use disorder: disulfiram discourages drinking by causing unpleasant symptoms, and naltrexone reduces craving and pleasure associated with drinking
- Behavioral therapies include cognitive-behavioral therapy (CBT) and contingency management
