Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for schizophrenia, particularly second-generation antipsychotics, work by modulating neurotransmitter activity in the brain, especially dopamine and serotonin pathways. This helps to reduce symptoms like hallucinations, delusions, and disorganized thinking. Understanding these mechanisms is important for patients as it guides the choice of treatment, balancing effectiveness with side effects, and aiming to enhance overall quality of life and daily functioning.
