Abstract
Based on the analogous structural formula of homopantothenic acid (HOPA) to pantothenic acid, the present authors assumed that HOPA might be antagonistic to pantothenic acid and give adverse influence on the liver functions. However, the experimental result demonstrated that long term administration of HOPA exerted no unfavourable influence on the liver function. Clinically, HOPA showed effects on idiopathic epliepsy, Jacksonian epilepsy, Parkinsonism, and tremor of extremity. HOPA is also considered to be effective for treatment of some other hyperkinetic disorders.
