In vivo study | PF-06700841 pharmacokinetic studies in Sprague − Dawley rats after intravenous injection of 1 mg/kg PF-06700841 tosylate or oral administration of 3 mg/kg PF-06700841 tosylate, the plasma clearance of PF-06700841 in vivo was 31 mL/min/kg, the volume of distribution was 2.0 L/kg, and its oral bioavailability was 83%. After oral administration of 3 mg/kg, its Cmax was 774 ng/mL and auc∞ was 1340 ng · h/mL. The high oral bioavailability of PF-06700841 indicates that it has a high intestinal Absorbability, which is associated with its passive osmotic activity and high solubility in vitro. |
