Antidopaminergic

Antidopaminergic (pronunciation: an-ti-doh-pa-mi-ner-jik) refers to a class of medications that inhibit the actions of dopamine in the brain.

Etymology

The term "antidopaminergic" is derived from the prefix "anti-", meaning against, and "dopaminergic", which refers to the actions of the neurotransmitter dopamine.

Definition

Antidopaminergic drugs work by blocking dopamine receptors in the brain. Dopamine is a type of neurotransmitter, a chemical that transmits signals in the brain. By blocking these receptors, antidopaminergic drugs can reduce the effects of dopamine, which can be useful in treating certain medical conditions.

Uses

Antidopaminergic drugs are used in the treatment of a variety of conditions, including schizophrenia, bipolar disorder, and nausea and vomiting caused by chemotherapy. They can also be used to treat Parkinson's disease, a condition characterized by low levels of dopamine in the brain.
