CENTRAL NERVOUS SYSTEM PHARMACOLOGY
Synopsis
Central Nervous System Pharmacology explores the mechanisms by which drugs influence brain and spinal cord function. It focuses on agents that either stimulate or depress neural activity, targeting neurotransmitter systems to treat neurological and psychiatric disorders. These drugs act on specific receptors—such as ionotropic and metabotropic types—modulating synaptic transmission and neuronal excitability.
Key neurotransmitters involved include dopamine, serotonin, GABA, glutamate, acetylcholine, and norepinephrine, each playing distinct roles in cognition, mood, motor control, and autonomic regulation. CNS-active drugs are classified into categories such as anxiolytics, antidepressants, antipsychotics, anticonvulsants, sedatives, stimulants, and neuroprotective agents.
Understanding CNS pharmacology is essential for developing therapies for conditions like depression, anxiety, epilepsy, Parkinson’s disease, schizophrenia, and Alzheimer’s disease. Advances in genomics and neuropharmacology are paving the way for personalized medicine and more targeted drug development strategies.
