Pentoxifylline-d6 (Synonyms: Oxpentifylline-d6)

Pentoxifylline-d₆ is intended for use as an internal standard for the quantification of pentoxifylline by GC- or LC-MS. Pentoxifylline is a hemorrheologic agent.¹ It increases the deformability of washed isolated human erythrocytes when used at a concentration of 100 µM.² Pentoxifylline (1, 2, and 3 mM) inhibits ADP-induced platelet aggregation in isolated human whole blood.³ It inhibits thrombus formation induced by ADP in a hamster cheek pouch model when administered at doses of 5, 10, and 20 mg/kg.⁴ Formulations containing pentoxifylline have been used in the treatment of intermittent claudication.
