EXPLORING THE ANTIPSYCHOTIC POTENTIAL OF ALLOPURINOL: TARGETING PURINE METABOLISM IN SCHIZOPHRENIA TREATMENT

The purinergic system, characterized by the signaling pathways mediated by purines such as adenosine and ATP, plays a significant role in the pathophysiology of schizophrenia. Recent research has highlighted the potential of allopurinol, a xanthine oxidase inhibitor traditionally used to manage hyperuricemia and gout, as an adjunctive treatment for schizophrenia. Allopurinols mechanism of action involves the modulation of adenosine metabolism, which may help restore neurotransmitter balance, particularly in the dopaminergic and glutamatergic systems involved in schizophrenia. Clinical studies show mixed results about the effectiveness of allopurinol. Some trials report that it significantly improves psychotic symptoms and cognitive problems, while others have inconclusive results. The variability in findings may be attributed to differences in study design, patient populations, and the specific symptoms assessed. allopurinol may help treat schizophrenia by reducing oxidative stress and inflammation in the brain. Its antioxidant properties support its potential as a useful therapy. Despite generally favorable safety and tolerabi
