Prescription Opioids. V. Metabolism and Excretion of Oxymorphone in Urine Following Controlled Single Dose Administration.

abstract：:The relationship between blood cocaine concentrations and pharmacological effects is of both theoretical and practical interest. This study utilized a computer-assisted smoking device for the delivery of three active doses (10, 20, and 40 mg) of cocaine base to seven human volunteers. Doses were administered in an asc...
