Interventions
ADVERSE EVENTS
Patients were randomly allocated to receive either 400 mg daily of Carnosine or identical placebo for a period of 3 months. L‐Carnosine dose was titrated to 800 mg in the next 3 months. This dose was decided based on previously conducted study by Chez et al (2002). Besides, the maximum dose of L‐Carnosine approved for research in India is 800 mg. Weekly telephonic interviews were conducted by research staff to ensure adherence and also to monitor for adverse events. Antipsychotic and other prescribed psychotropic medications were continued (treatment as usual) during the entire study period. Participants were instructed not to take any other vitamins and carnosine supplements, while maintaining their regular diet and physical activity during the trial.
