In Vivo	Zoxazolamine is widely used for a pharmacologic test that serves as a convenient indicator of changes in cytochrome P-450 activity in rodents. The time-averaged serum clearance determined from tested concentrations data is 7.22±1.01 mL/min/kg for Zoxazolamine. Infusion of Zoxazolamine to righting reflex (LRR) at three different rates shows increasing Zoxazolamine concentration in serum and brain at the onset of the effect with increasing infusion rates. When the Zoxazolamine infusion is continued for 5 min beyond the onset of LRR, the concentrations of Zoxazolamine in the cerebrospinal fluid (CSF) at the offset of LRR are essentially identical to the onset concentrations[1].
Animal Admin	Inbred male Lewis rats are used in this study. The animals are allowed 7 to 12 days to adjust to the local animal facilities and to recover possible stress incurred during transport. To compare drug concentrations in serum at the onset and offset of loss of the righting reflex, Zoxazolamine is infused into the femoral vein at a rate of 0.51 mg/min for 5 min beyond the onset of loss of the righting reflex. The infusion solution consists of 10 mg Zoxazolamine in 1 mL normal saline. Then, blood samples from the jugular vein are obtained from four rates at the onset and offset of loss of the righting reflex, using a procedure that yields mainstream blood[1].
