From the Guidelines
The main classes of psychiatric medications include antidepressants, antipsychotics, mood stabilizers, anxiolytics, and stimulants. These classes of medications are used to treat a variety of psychiatric conditions, including depression, anxiety disorders, schizophrenia, bipolar disorder, and attention deficit hyperactivity disorder (ADHD) 1.
Medication Classes
- Antidepressants, such as SSRIs (fluoxetine, sertraline, escitalopram), SNRIs (venlafaxine, duloxetine), and atypical antidepressants (bupropion, mirtazapine), work by increasing neurotransmitters like serotonin and norepinephrine to treat depression and anxiety disorders 1.
- Antipsychotics, including typical (haloperidol, chlorpromazine) and atypical (risperidone, olanzapine, quetiapine, aripiprazole) medications, block dopamine receptors to manage schizophrenia, bipolar disorder, and other psychotic conditions.
- Mood stabilizers, such as lithium, valproate, and lamotrigine, help regulate emotional extremes in bipolar disorder by affecting neurotransmitter systems and neural signaling.
- Anxiolytics, primarily benzodiazepines (lorazepam, clonazepam, alprazolam), enhance GABA activity to reduce anxiety but carry addiction risks with long-term use.
- Stimulants, like methylphenidate and amphetamine derivatives, increase dopamine and norepinephrine to improve focus and reduce impulsivity in ADHD.
Key Considerations
When prescribing these medications, it is essential to consider individual patient factors, including age, medical history, and potential drug interactions, as well as specific dosing requirements, side effect profiles, and contraindications 1.
Monitoring and Treatment
Regular monitoring of patient status, therapeutic response, and adverse effects is crucial, beginning within 1 to 2 weeks of initiation of therapy, and modifying treatment if the patient does not have an adequate response within 6 to 8 weeks 1.
From the Research
Main Classes of Psychiatric Medications
The main classes of psychiatric medications include:
- Selective serotonin-reuptake inhibitors (SSRIs)
- Tricyclic antidepressants
- Monoamine oxidase inhibitors
- Other classes of antidepressants such as heterocyclic and new-generation antidepressants
Selective Serotonin-Reuptake Inhibitors (SSRIs)
SSRIs are a class of drugs used in the treatment of depression and related disorders 2, 3, 4, 5, 6. They are chemically unrelated to tricyclic, heterocyclic, and other first-generation antidepressants. Examples of SSRIs include:
- Fluoxetine
- Sertraline
- Paroxetine
- Fluvoxamine
- Citalopram
- Escitalopram
- Vilazodone
Indications for SSRIs
SSRIs are used to treat a variety of conditions, including:
- Major depression
- Dysthymia
- Panic disorder
- Obsessive-compulsive disorder
- Eating disorders
- Social phobia
- Premenstrual dysphoric disorder
- Bulimia
- Chronic pain syndromes
Characteristics of SSRIs
SSRIs have several characteristics that make them a popular choice for treating depression and related disorders, including:
