Summary for Patent: 5,135,943

Title: 1H-imidazole derivative compounds and pharmaceutical compositions containing the same
Abstract:The 1H-imidazole derivative compound of formula I: ##STR1## and its nontoxic addition salts, particularly the nitrate addition salt, are more effective as antimycotic agents and are unexpectedly safer than the corresponding prior art compounds, especially the compound in which the sulfur atom of the benzothiophene ring of the above compound is replaced by an oxygen atom. Pharmaceutical compositions containing an effective amount of the compound of formula I, e.g. 1 to 5% by weight, in a pharmaceutical carrier are safer, more effective, and, in some cases, more reliable with fewer side effects than currently used antimycotic preparations.
