D2 receptor partial agonist

A D2 receptor partial agonist is a type of medication that interacts with dopamine D2 receptors in the brain. Unlike full agonists that fully activate these receptors or antagonists that block them, partial agonists activate them only partially. This means they can help balance dopamine activity—reducing excessive signals in some cases or boosting them when signals are too low. Such medications are often used in treating conditions like schizophrenia or bipolar disorder, aiming to normalize dopamine activity without causing complete activation or blockade, which helps manage symptoms while minimizing side effects.
