Zoxazolamine is a centrally acting muscle relaxant. It decreased striatal dopamine metabolism without affecting striatal dopamine concentrations. More specifically, Zoxazolamine was shown to decrease striatal dopamine turnover without directly affecting dopamine synthesis, catabolism, reuptake, or release. It is the IK(Ca) channel opener. It was approved for the relief of muscle spasm in conditions such as musculoskeletal disorders and neurological diseases. Later, it was submitted for the drug's use as a uricosuric agent to treat gout. It was withdrawn from the market due to hepatotoxicity.
