Liver injury due to exenatide must be rare, if it occurs at all. In large clinical trials, serum enzyme elevations were no more common with exenatide therapy than with placebo or comparator agents, and no instances of clinically apparent liver injury were reported. Since licensure, there have been no published case reports of hepatotoxicity due to exenatide and the product label does not list liver injury as an adverse event. Exenatide has been linked to rare instances of acute pancreatitis, but even this complication is usually not associated with elevations in serum bilirubin and aminotransferase levels.

Following a single dose of Bydureon, exenatide is released from the microspheres over approximately 10 weeks. There is an initial period of release of surface-bound exenatide followed by a gradual release of exenatide from the microspheres, which results in two subsequent peaks of exenatide in plasma at around week 2 and week 6 to 7, respectively, representing the hydration and erosion of the microspheres. Following initiation of once every 7 days (weekly) administration of 2 mg Bydureon, gradual increase in the plasma exenatide concentration is observed over 6 to 7 weeks. After 6 to 7 weeks, mean exenatide concentrations of approximately 300 pg/mL were maintained over once every 7 days (weekly) dosing intervals indicating that steady state was achieved.
Nonclinical studies have shown that exenatide is predominantly eliminated by glomerular filtration with subsequent proteolytic degradation. The mean apparent clearance of exenatide in humans is 9.1 L/hr and the mean terminal half-life is 2.4 hr. These pharmacokinetic characteristics of exenatide are independent of the dose. In most individuals, exenatide concentrations are measurable for approximately 10 hr post-dose.

皮下注射单剂量的百泌达后,艾塞那肽的平均表观分布体积为28.3升。
The mean apparent volume of distribution of exenatide following SC administration of a single dose of Byetta is 28.3 L.
Following SC administration to patients with type 2 diabetes, exenatide reaches median peak plasma concentrations in 2.1 hr. The mean peak exenatide concentration (Cmax) was 211 pg/mL and overall mean area under the time-concentration curve (AUC0-inf) was 1036 pg hr/mL following SC administration of a 10 ug dose of Byetta. Exenatide exposure (AUC) increased proportionally over the therapeutic dose range of 5 ug to 10 ug. The Cmax values increased less than proportionally over the same range. Similar exposure is achieved with SC administration of Byetta in the abdomen, thigh, or upper arm.
