    摘要: The invention provides various medical compositions for use in treating or preventing certain of the side effects of diabetes or galactosemia. The active ingredients are selected from a series of novel aldose reductase inhibitory spiro-linked pyrrolidine-2,5-diones of the general formula: ##STR1## or a pharmaceutically acceptable salt, or a non-toxic, biodegradable precursor thereof. Processes for the production of these compounds are also provided. A particular compound suitable for use as an active ingredient is spiro[pyrrolidine-3,9'-xanthene]-2,5-dione.
