Abstract

1,250,279. Decarboxylase-inhibiting medicines. F. HOFFMANN-LA ROCHE & CO. A.G. 14 Aug., 1969 [16 Aug., 1968], No. 40603/69. Heading A5B. [Also in Division C2] Pharmaceutical compositions, having decarboxylase-inhibiting activity suitable for oral or parenteral administration, contain a hydrazide of the formula or acid addition salts thereof in association with compatible pharmaceutical carriers. The composiltionis may also contain L-dopa or acid addition salts thereof and may be used in the treatment of Parkinsonism. [GB1250279A]
