This modulation of neurotransmitter activity in the brain is believed to help alleviate symptoms of schizophrenia.

Aristada is available in two dosage strengths: 441 mg and 662 mg [1]. These strengths are formulated for intramuscular injection.

What are the alternatives to Aristada for schizophrenia treatment?
