The treatment of lewisite intoxication with dimercaptosuccinic acidthrough the intravenous route in animal experiments

Objective: To prepare antidote of the type of dimercaptosuccinic acid (DMSA) for the treatment of animal with heavy lewisite intoxication through intravenous injection. Methods: The raw material of DMSA in the oral capsule was purified with a twostep method, then the drug was tested through intravenous injection in the animal experiments. Results: The purity of DMSA was increased from 9379% to 9968%; Element analysis, IR spectrum, melting point determination, bacteria and pyrogen examination were up to the standards, and intravenous injection of it was very effective in treatment of lewisite intoxication in dogs and rats . Conclusion: DMSA raw material in the oral capsule can be used for intravenous injection after purification, its effectiveness in treating the lewisite intoxication in animal experiments is quite satisfactory. These results will provide some experimental data for the pharmaceutical and clinical researches.
