Evaluation of antidotes: activities of the International Programme on Chemical Safety.

Important developments concerning the role of antidotes in managing poisoning cases have taken place in recent decades due to new toxicodynamic and toxicokinetic studies and to growing international concern regarding the effectiveness of antidotes. A number of activities are carried out by the International Programme on Chemical Safety which aim to: (1) evaluate their effectiveness in clinical practice, (2) disseminate evaluated information, and (3) promote the availability of useful antidotes. The International Programme on Chemical Safety has undertaken the preparation of Antidote Monographs that summarize and assess the clinical use, mode of action, effectiveness, and other evaluated information, and a consolidated International Programme on Chemical Safety List of Antidotes that classifies antidotes and related drugs by their clinical effectiveness and urgency of need. A chart of Antidote Dosages, with information concerning the recommended antidotes and their indications, is being prepared, and the Availability of Antidotes in different countries is being surveyed. Further International Programme on Chemical Safety initiatives are also being undertaken in the area of antidotes and clinical toxicology in order to examine particular issues. The International Programme on Chemical Safety INTOX Project and related activities provide powerful tools for multicenter studies, but such research faces continuing financial and regulatory difficulties. Twinning arrangements between scientists from different parts of the world are being promoted to enhance the capabilities of evaluating treatment procedures and to compare clinical data. International organizations have important aims: to promote adequate and appropriate regulations and increase antidote availability, to establish international consensus and to increase interest in co-operative research. Cooperation with scientific bodies is essential in supporting these aims.
