Psychiatric medication

A psychiatric medication is a licensed psychoactive drug taken to exert an effect on the chemical makeup of the brain and nervous system. Thus, these medications are used to treat mental illnesses. Usually prescribed in psychiatric settings, these medications are typically made of synthetic chemical compounds. Since the mid-20th century, such medications have been leading treatments for a broad range of mental disorders and have decreased the need for long-term hospitalization, therefore lowering the cost of mental health care. The recidivism or rehospitalization of the mentally ill is at a high rate in many countries and the reasons for the relapses are under research.

Modern psychiatric medication has advanced greatly in the past century. The reuptake hypothesis by Julius Axelrod involves the interaction among neurotransmitters, and forms the cornerstone of the development of modern psychotropic drugs. His work allowed researchers to further advance their studies into the effects of psychiatric medication. Mental health medications were first introduced in the mid-20th century with the widespread introduction of chlorpromazine, an antipsychotic. The popularity of these drugs have skyrocketed since then, with millions prescribed annually.

As of 2013, the 10 most prescribed psychiatric drugs by number of prescriptions were alprazolam, sertraline, citalopram, fluoxetine, lorazepam, trazodone, escitalopram, duloxetine, bupropion XL, and venlafaxine XR.

Psychiatric medications are prescription medications, requiring a prescription from a physician, such as a psychiatrist, or a psychiatric nurse practitioner, PMHNP, before they can be obtained. Some U.S. states and territories, following the creation of the prescriptive authority for psychologists movement, have granted prescriptive privileges to clinical psychologists who have undergone additional specialised education and training in medical psychology. In addition to the familiar dosage in pill form, psychiatric medications are evolving into more novel methods of drug delivery. New technologies include transdermal, transmucosal, inhalation, and suppository supplements.
