INTERNATIONAL JOURNAL OF NEUROPSYCHOPHARMACOLOGY

INTERNATIONAL JOURNAL OF NEUROPSYCHOPHARMACOLOGY is published by Oxford University Press and is in Zone 2 of Medicine in the CAS Journal Ranking (2025 upgraded edition).

(generated from OpenAlex topic counts and CAS ranking data)

The central focus of the journal is on research that advances understanding of existing and new neuropsychopharmacological agents including their mode of action and clinical application or provides insights into the biological basis of psychiatric disorders and thereby advances their pharmacological treatment. Such research may derive from the full spectrum of biological and psychological fields of inquiry encompassing classical and novel techniques in neuropsychopharmacology as well as strategies such as neuroimaging, genetics, psychoneuroendocrinology and neuropsychology. Emphasis is given to original research (in the form of full-length papers and brief reports), which is of wide interest and clearly advances the field. Selected review articles and papers that highlight novel trends and perspectives are also considered.
