What Is Psychopharmacology?

In psychiatry, psychopharmacology refers to the practice of treating mental health conditions with medication. Some patients with mental health conditions may benefit from prescription drugs that manage chemical balances in the brain. Psychopharmacology services involve prescribing these medicines and monitoring their doses. As a psychopharmacology patient at Principium Psychiatry, you’ll get expert prescribing and medication monitoring.

Psychopharmacologist vs. Psychiatrist

The fields of psychopharmacology and psychiatry overlap in many elements, with a few differences between the terms. A psychiatrist provides mental health care using a combination of techniques, including psychopharmacology. A psychopharmacologist specializes in mental health medication. Our staff has expertise in both fields and will help you find a treatment focus that works for your symptoms.

Types of Mental Health Medications and Treatments

Just as many kinds of mental health conditions exist, so do medications for these disorders. The right type of medicine for a patient depends on their diagnosis and symptoms. Different mental health medications include:

  • Antidepressants: Doctors prescribe antidepressants to treat depression. An antidepressant falls into a category such as SSRI or SNRI, depending on its interaction with the brain.
  • Anti-anxiety medications: Medications for anxiety can address generalized symptoms or sudden symptoms such as panic attacks. These medicines work on a short-term or long-term basis, depending on the symptoms that they target.
  • Antipsychotics: Antipsychotics treat psychosis, a category of symptoms that impact someone’s perception of reality. Psychosis-related conditions include schizophrenia, bipolar disorder or psychotic depression.
  • Stimulants: Stimulant medications increase attention and alertness. Doctors most often prescribe these medications for people with ADHD to help them focus. They can also treat narcolepsy and select cases of depression.
  • Mood stabilizers: Mood stabilizers address bipolar disorder symptoms and mood swings associated with other conditions. They can also enhance the effects of antidepressants.

Benefits of Psychopharmacology

As a treatment for mental health conditions, psychopharmacology at Principium Psychiatry provides the following benefits:

  • Tailored treatment plans: Our doctors will customize your treatment plan based on your medical profile, symptoms, situation and preferences.
  • Combining with other therapies: We can combine psychopharmacology with other treatments such as psychotherapy to address your symptoms.
  • Different dosage options: A wide range of mental health medications and dosages exist, making it possible to adjust treatment over time.
