5、han that of Octreotide-soln treated group 1. A testdose of octreotide acetate significantly decreases the serum gastrin level to approximately one third of thebaseline in 2 hr and the effect lasted approximately for 6 hr.

Rats are subcutaneously injected with Octreotidereotidesolution (Octreotide-soln) or Octreotide-PPSG at an equivalent single dose of 20 mg/kg. The dose isdetermined based on the clinical dose of

10、 Octreotide-soln in human. Rats are fasted for 12 h before dosingand food is returned approximately 2 h post dosing. Blood samples are collected at predetermined timepoints using heparinized Eppendorf tubes. Immediately after collection, the blood samples are placed on iceuntil centrifuged at 3000 g
