International Agranulocytosis and Aplastic Anemia Study. Risks of agranulocytosis and aplastic anemia. A first report of their relation to drug use with special reference to analgesics. JAMA. 1986;256(13):1749-1757. (This landmark study established the strong link between pyrazolone derivatives like dipyrone/aminophenazone and agranulocytosis, which applies to the entire class, including perisoxal).

Leitner, J. M., et al. Pyrazolone derivatives and the risk of agranulocytosis: a systematic review and meta-analysis. Fundam Clin Pharmacol. 2021;35(3):498-508. (Confirms the significant risk of agranulocytosis associated with pyrazolone drugs).
Martindale: The Complete Drug Reference (Historical Editions). London, UK: Pharmaceutical Press. (Older editions may contain brief pharmacological descriptions and historical use information for Perisoxal, classifying it as a pyrazolone NSAID. Crucially, modern editions reflect its withdrawn/not marketed status globally).
Index Nominum (International Drug Directory) (Historical Editions). Swiss Pharmaceutical Society. (Similar to Martindale, historical entries may exist but confirm its non-availability).
PubChem Compound Database. Perisoxal (CID: 71697). National Center for Biotechnology Information. (Provides chemical structure and basic identifiers, confirming its classification as an organic compound/pyrazolone derivative). Accessed via: https://pubchem.ncbi.nlm.nih.gov/compound/71697
European Medicines Agency (EMA) and US Food and Drug Administration (FDA) Databases. Public assessment reports and drug approval databases. (Searches confirm no current marketing authorization for Perisoxal in the EU or US. The EMA’s strict stance on pyrazolone safety like dipyrone directly informs the status of Perisoxal).
World Health Organization (WHO) Model Lists of Essential Medicines. (Perisoxal has never been listed, reflecting its lack of essential status and safety concerns compared to established analgesics/antipyretics).
Arzneimittel-Kompendium der Schweiz / Rote Liste (Germany) (Historical Editions). (Historical compendia may have listed Perisoxal, but modern versions do not, indicating its discontinuation/withdrawal in those markets).
Textbooks of Pharmacology & Therapeutics (Historical Editions): e.g., Goodman & Gilman's, Katzung's. (May contain brief mentions in sections on older NSAIDs/pyrazolones, emphasizing their hematological risks and superseded status).
