Megamentin a combined antibiotic comprising amoxycillin and clavulanic acid, with a broad spectrum bactericidal action, resistant to beta-lactamase.
Amoxicillin – is a semi-synthetic broad-spectrum antibiotic active against many gram-positive and gram-negative microorganisms.Amoxicillin collapses under deystviembeta-lactamases, and has no effect on the microorganisms which produce etoferment. Its mechanism of action is to inhibit biosintezamukopeptidov cell wall.
Clavulanic acid – a beta-laktamat structurally related penicillins, which has the ability to inactivate a wide spektrbeta-lactamase. Beta-lactamases are produced by many gram-positive bacteria igramotritsatelnymi. The action of beta-lactamases can lead krazrusheniyu some antibacterial drugs even before they vozdeystviyana pathogens. Clavulanic acid blocks the action of enzymes, bacteria vosstanavlivayachuvstvitelnost to amoxycillin. In particular, it has vysokoyaktivnostyu plasmid against beta-lactamases, which often svyazanalekarstvennaya resistance, but is less effective against hromosomnyhbeta lactamase-1 type.
The presence of clavulanic acid in the Megamentin protects amoxicillin from the destructive action of beta-lactamases and extends its spectrum of antibacterial activity to include the microorganisms normally resistant to other cephalosporins and penicillins.
