Furazolidone 50 mg Pharmacodynamics
Antimicrobial and antiprotozoal agent, nitrofuran derivative. Active against the following microorganisms: Trichomonas spp., Giardia lamblia, Shigella dusenteriae, Shigella flexneri, Shigella boydii, Shigella sonnei, Salmonella typhi, Salmonella paratyphi, Staphylococcus spp.
Weak effect on pathogens of purulent and anaerobic infection. Resistance of microorganisms develops slowly. It blocks monoamine oxidase.
Nitrofurans disrupt cellular respiration of microorganisms, inhibit tricarboxylic acid cycle and also inhibit nucleic acid biosynthesis of microorganisms, resulting in destruction of their shell or cytoplasmic membrane. As a result of the action of nitrofurans, microorganisms release fewer toxins, so improvement of the patient’s general condition is possible even before a pronounced suppression of microflora growth. Unlike many other antimicrobial drugs, they not only do not suppress, but even activate the immune system of the body (increase the complement titer and the ability of leukocytes to phagocytize microorganisms).
