Background:

Atypical antipsychotics offer alternatives to conventional treatments for schizophrenia, with reduced extrapyramidal side effects.
Current antipsychotic mechanisms extend beyond dopamine D2 receptor antagonism.

Purpose of the Study:

To review current developments in antipsychotic drug discovery.
To examine contemporary evidence for potential substrates and mechanisms of antipsychotic action.

Main Methods:

Literature review of recent advancements in antipsychotic drug discovery.
Analysis of contemporary evidence on drug targets and mechanisms.

Main Results:

Several atypical antipsychotics are available, demonstrating efficacy comparable to conventional treatments with fewer side effects.
Numerous novel antipsychotic drugs are under development with diverse receptor affinities and proposed therapeutic effects.

Conclusions:

Despite promising developments, an ideal antipsychotic for schizophrenia treatment has not yet been achieved.
Significant challenges remain in schizophrenia drug treatment, requiring further research for substantial advances.
