Relapse and acute exacerbation are common in schizophrenia may impact treatment response outcome. Evidence is conflicting respect to superiority of long-acting injectable antipsychotic therapies versus oral antipsychotics relapse prevention. This randomized controlled study assessed the efficacy paliperidone palmitate for prevention.Eligible patients with a recent diagnosis (within 1-5 years) were 1:1 (n=376) or monotherapy (n=388) entered 2-week initial phase. Patients who met predefined...
