Q

Sitagliptin (DPP4 inhibitors)

  • With IV admin; dysrhythmia, hypotension, purple glove syndrome

exhibits saturable kinetics; lower dose, SMALLER half life! 1st order kinetics
-minimal changes in dose, large changes in concentration

Class: H2 Receptor Antagonist

Action: Suppresses the secretion of gastric acid by selective blocking H2 receptors in parietal cells lining stomach

AE: -caution in preg

  • multiple drug interactions (CYP450)
  • doses need to be adjusted in renal insufficiency
