Metronidazole Mechanism Of Action

The precise mechanism of action of metronidazole is unclear. These cytotoxic compounds damage dna and other critical intracellular macromolecules.

Mechanism of action activity against most obligate anaerobes occurs through a four step process.

Metronidazole mechanism of action. The mechanisms of metronidazole resistance are complex manifesting as reduced rate of uptake by efflux or by reducing the rate of metronidazole reductive activation for instance by altering pyruvate fermentation. Entry into the microorganism metronidazole is a low molecular weight compound that diffuses across the cell membranes of anaerobic and aerobic microorganisms. A potential for development of resistance exists against metronidazole.

Mechanism of action metronidazole flagyl medication works by entering the aerobic bacterium and by use of the electron transport protein ferrodoxin it is negated. Following this ferredoxin or flavodoxin reduce its nitro group to nitro radicals. Inactivating resistance determinants summarized in figure 3 and increased dna repair efficiency provide additional mechanisms.

However antimicrobial activity is limited to anaerobes 3. Mechanism of action metronidazole is of the nitroimidazole class. Then clamping onto the dna the drug splinters it up.

The precise mechanism of action of metronidazole is unclear. The reduced form of metronidazole and free radicals can interact with dna leading to inhibition of dna synthesis and dna degradation leading to death of the bacteria. 14 after administration metronidazole enters cells by passive diffusion.

The exact mechanism of action of metronidazole has not been fully established however it is possible that an intermediate in the reduction of metronidazole which is only made by anaerobic bacteria and protozoa binds deoxyribonucleic acid and electron transport proteins of organisms blocking nucleic acid synthesis. The reduced form of metronidazole and free radicals can interact with dna leading to inhibition of dna synthesis and dna degradation leading to death of the bacteria. Metronidazole is a prodrug that is reduced in the cytoplasm by a nitroreductase enzyme.

Metronidazole triggers antioxidant activity as indicated by in vitro data and may prevent and fight rosacea symptoms. Metronidazole has bactericidal activity against a broad spectrum of anaerobic bacteria and selected protozoans. The exact mechanism of action of metronidazole has not been fully established however it is possible that an intermediate in the reduction of metronidazole which is only made by anaerobic bacteria and protozoa binds deoxyribonucleic acid and electron transport proteins of organisms blocking nucleic acid synthesis l3754 after administration metronidazole enters cells by passive diffusion.

It inhibits nucleic acid synthesis by disrupting the dna of microbial cells. Resulting toxic intermediates disrupt nucleic acid structure. Mechanism of action metronidazole is rapidly taken up by bacteria where it is metabolized by a reduction process to cytotoxic derivatives short lived free radical compounds.
