Pharmacological activity and toxicity of apyramide: comparison with non-steroidal anti-inflammatory agents

An experimental and comparative study was conducted on 1-(p-chlorobenzoyl)-2-methyl-5-methoxyindole-3-p-acetamidophenol acetate (Apyramide) and known anti-inflammatory agents. Apyramide was far less toxic than indomethacin in rats and mice by the oral or the i.p. route. It exhibited anti-inflammatory activity on carrageenin-induced paw oedema, cotton pellet granuloma and Adjuvant arthritis, as well as analgesic and antipyretic activities. The acute ulcerogenic effect of Apyramide was lower than that of indomethacin.
