How Do Antimanic Agents Work?

Antimanic agents are medications used as mood stabilizers in psychiatric conditions such as bipolar disorder and schizophrenia. In addition, some antimanic agents control abnormal electrical activity in the brain and are used to treat neurological conditions such as epilepsy and trigeminal neuralgia.

Antimanic agents control mania, an extremely euphoric and excited mood associated with psychiatric disorders. Antimanic agents also control involuntary muscle contractions or pain caused by the abnormal firing of nerve cells (neurons). Antimanic agents work by regulating the chemical balance and activity, and electrical activity in the brain.

Antimanic agents help reduce manic excitement by acting on several neurotransmitters such as dopamine, serotonin and norepinephrine, which are chemical messengers that neurons release to communicate with each other and stimulate activity. 

Antimanic agents primarily block D2 dopamine receptors and 5-HT2A serotonin receptors, which are protein molecules that initiate excitatory action when stimulated by these neurotransmitters. Some antimanic agents stimulate H1 histamine receptors in the central nervous system, producing sedation and calming effects. 

Antimanic agents prevent abnormal electrical impulses by stabilizing the sodium channels in neurons and reducing their electrical conductivity.
