Cinepazide or cinepazide maleate[1] (Kelinao or Anjieli in China[2][3]) is a vasodilator used in China for the treatment of cardiovascular and cerebrovascular diseases, and peripheral vascular diseases.

[5] Cinepazide was discovered by scientists at Laboratoires Delalande (now part of Sanofi) in 1969 in an effort to explore useful substituted cinnamoyl-piperazine compounds.

[6][7] The drug, in the form of a pill taken orally, was launched by Delalande in 1976 under the tradename Vasodistal, for treatment of heart failure, balance disorders, cerebrovascular disease, and vascular complications of diabetes.

[12] In 2002 Sihuan Pharmaceutical brought an injectable form of the drug to market in China;[13] Sihuan had acquired the drug from a military hospital in China that had developed the formulation.

[13][3] This made Sihuan Pharm the largest company in China in the cardio-cerebral vascular drug market in 2010.
