Purity >98%. Zoxazolamine is a potent skeletal muscle relaxant that also has uricosuric activity. It is metabolized by an array of cytochrome P450 (CYP450) isoforms. As a result, recovery time from zoxazolamine-induced paralysis is used as a measure for change in CYP450 expression in mice. Zoxazolamine also dose-dependently modulates the expression of pigmentation factors in a keratinocyte-melanocyte co-culture system.
