  • Antibacterial pharmaceutical composition
    Patent number: 4500516
    Abstract: Disclosed is an antibacterial pharmaceutical composition comprising potasm salt of N-[.beta.-(5'-nitrofuryl-2')-acrylidene]-1-aminohydantoin and basic magnesium carbonate in conjunction with a pharmaceutically suitable filler.The proposed antibacterial pharmaceutical composition has a broader spectrum of action and a higher biological accessibility than the other antibacterial pharmaceutical compositions of the nitrofuran series known in the prior art. The proposed pharmaceutical composition is considerably less toxic than the prior-art antibacterial pharmaceutical compositions of the nitrofuran series and affords a bacteriostatic effect exceeding appreciably that of the prior-art antibacterial pharmaceutical compositions of the nitrofuran series.
