Fluvoxamine dose-dependent interaction with haloperidol and the effects on negative symptoms in schizophrenia.

abstract：RATIONALE:In patients, ketamine is a fast-acting antidepressant that can induce long-lasting symptom relief. Similar rapid effects have been reported in rodents, but reports of lasting effects are limited. OBJECTIVES:We sought to extend past findings by examining dose-response curves that overlap with the individual d...
