Lenperone (Elanone-V) is a typical antipsychotic of the butyrophenone chemical class.[1] It was first reported as an emetic in 1974,[2] and its use in treatment of acute schizophrenia was reported in 1975.[1] Related early antipsychotic agents include declenperone and milenperone.

Lenperone was never approved by the FDA for use in humans in the United States,[3] but prior to 1989 it was approved for use in veterinary medicine for sedation.[4][5][6]
