Once metronidazole enters the organism by passive diffusion and activated in the cytoplasm of susceptible anaerobic bacteria, it is reduced; this process includes intra-cellular electron like the selective COX-2 inhibitors, paracetamol does not suppress the inflammation of rheumatoid arthritis. It does, however, decrease swelling after oral surgery in humans and suppresses inflammation in rats and mice. Paracetamol is a weak inhibitor of PG synthesis of COX-1 and COX-2 in broken cell systems, but, by contrast, therapeutic concentrations of paracetamol inhibit PG synthesis in ...Five Basic Mechanisms of Antibiotic Action against Bacterial Cells. Inhibition of Cell Wall Synthesis (most common mechanism) Inhibition of Protein Synthesis (Translation) (second largest class) Alteration of Cell Membranes. Inhibition of Nucleic Acid Synthesis. Antimetabolite Activity.In fact, oral metronidazole has been advocated as first-line therapy. Adverse effects include gastrointestinal irritation and a disulfiramlike action; thus, abstinence from alcohol is required.Resistance Mechanism of C. difficile to Most Commonly Used Drugs Recommended for CDI Treatment 3.1. Metronidazole. Metronidazole is a nitroaromatic drug that requires reduction of the 5-nitro group of its imidazole ring to become cytotoxic to bacterial cells . Metronidazole is the first-choice antimicrobial drug for treating mild to moderate CDI .Metronidazole resistance is attributed to a mutation resulting in a strain of H pylori with defective nitroreductase. 13 Metronidazole is stable at a low pH and is actively secreted into the gastric juice. Active secretion of metronidazole is diminished when it is given with a proton pump inhibitor. 8 It has a half-life of 8 to 12 hours. The ...How does it work (mechanism of action)? Metronidazole is a synthetic (man-made) drug that is effective against certain bacteria and parasites (protozoa). The topical forms (gels, creams, and lotions) of metronidazole are used for treating vaginal infections with protozoa such as Trichomonas vaginalis , amoeba, and Giardia . Jul 08, 2009 · Metronidazole was introduced in 1959 for the treatment of Trichomonas vaginalis , but was subsequently shown to be active against anaerobic and some micro-aerophilic bacteria as well. In anaerobic microorganisms with their low redox potential, metronidazole is reduced to its active metabolite by a oneelectron transfer step. In fact, metronidazole's mode of action is fiendishly simple: it enters the cell without the help of any transporting mechanisms and unfolds its destructive potential after having been reduced to its nitro group, a reaction which occurs only under very low oxygen concentrations.Mechanism of Action . Metronidazole, a nitroimidazole, exerts antibacterial effects in an anaerobic environment against most obligate anaerobes. Once metronidazole enters the organism by passive diffusion and activated in the cytoplasm of susceptible anaerobic bacteria, it is reduced; this process includes intra-cellular electron Metronidazole is rapidly and almost completely absorbed on administration of Metronidazole tablets; peak plasma concentrations occur after 20 min to 3 hours.

The precise mechanism of action of metronidazole is unclear. Resistance. A potential for development of resistance exists against metronidazole. 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. Inactivating resistance determinants (summarized in Figure 3) and increased DNA repair efficiency provide additional mechanisms.The mechanism of action of metronidazole is not well understood. In the parasite, the 5-nitro group of the drug undergoes reductive transformation to a cytotoxic intermediate which binds to the helical structure of the DNA leading to strand breakage and eventual cell death [2].Chemotherapy is the treatment procedures depicting the effect of antibiotics on infections caused due to micro organism. Based on their Mechanism of Action Antibiotics are classified depending on the effect they have on the micro organisms which results in either Bacteristatistic or Bactericidal action. One example is beta lactamase, which is a bacterial enzyme that destroys antimicrobials that contain a beta lactam ring, like penicillins and cephalosporins. As a result, bacteria that produce beta lactamases are immune to the action of many beta lactam antibiotics. The second mechanism is the alteration of a target, or binding site.Anaerobic bacterial infection: 15 mg/kg IV infused over 1 hr; then 7.5 mg/kg infused over 1 hr q 6 hr for 7–10 days, not to exceed 4 g/day.
