Detailed Description:

Immune-related disorders have been hypothesized as etiological factors in schizophrenia.Minocycline is a second-generation tetracycline that exerts anti-inflammatory and antimicrobial effects while having a distinct neuroprotective profile.This study was performed as a double-blind, placebocontrolled,randomized evaluation of Second generation antipsychotics(SGA) and minocycline versus SGA and placebo.
