Metronidazole - General information
Metronidazole is one of few antibacterial drugs which effectively destroys protozoa agents of the infections. It is not typical antibacterial product, therefore its pharmacological action has broader spectrum.
Metronidazole provides antimicrobial, antibacterial, antiprotozoal, trichomonicidal, and antiulcer action. The drug is released in different medical forms and may be used for the treatment of the infections of the various sites. Due to this, Metronidazole has become a leading medicine for the treatment of the infections caused by protozoa organisms.
These are infections which are not treatable by the usual antibiotics. The germs often do not react to the bactericidal or bacteriostatic properties of the advanced drugs such as penicillin, macrolides, etc.
The mechanism of the action of Metronidazole differs from the action of many antibacterial drugs. When the active components reach the body, the drug quickly penetrates into the tissues and liquids, slips into the respiratory chain of protozoa and anaerobe and causes the disorder in the respiratory processes. Due to no ability to take in oxygen the microorganisms quickly stop developing and die.
Using Metronidazole in the higher doses the concentration of the active ingredients in the tissues and liquids is increased, and it allows to struggle with more complicated infectious processes. Metronidazole in high doses inhibits the DNA synthesis of bacteria, and they die.
