Open AccessDifferences in autonomic nervous system activity between long-acting injectable aripiprazole and oral aripiprazole in schizophrenia
Distinct oral atypical antipsychotics have different effects on autonomic nervous system (ANS) activity. Among them, oral aripiprazole has been linked to dysfunction of the ANS in schizophrenia. Long-acting in...
