Silver salt derived from naphthyridine, useful as a bactericide, process for its preparation and compositions containing it.

摘要

The invention relates to the silver salt of 1-ethyl-6-fluoro-1,4- dihydro-4-oxo-7-(1-piperazinyl)-1,8-naphthyridine-3-carboxylic acid. This derivative can be obtained, after dissolving the acid in an alkali metal hydroxide, by precipitation with a silver salt. The product thus obtained can be used, by itself or combined, in pharmaceutical compositions for the local treatment of infections, burns, and the like.
