| Mechanism of Action |
Metronidazole¿¡ ´ëÇÑ Mechanism_Of_Action Á¤º¸ Unionized metronidazole is selective for anaerobic bacteria due to their ability to intracellularly reduce metronidazole to its active form. This reduced metronidazole then disrupts DNA's helical structure, inhibiting bacterial nucleic acid synthesis and resulting in bacterial cell death.
|
| Pharmacology |
Metronidazole¿¡ ´ëÇÑ Pharmacology Á¤º¸ Metronidazole, a synthetic antibacterial and antiprotozoal agent of the nitroimidazole class, is used against protozoa such as Trichomonas vaginalis, amebiasis, and giardiasis. Metronidazole is extremely effective against anaerobic bacterial infections and is also used to treat Crohn's disease, antibiotic-associated diarrhea, and rosacea.

| Description |
Metronidazole¿¡ ´ëÇÑ Description Á¤º¸ A nitroimidazole used to treat amebiasis; vaginitis; trichomonas infections; giardiasis; anaerobic bacteria; and treponemal infections. It has also been proposed as a radiation sensitizer for hypoxic cells. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985, p133), this substance may reasonably be anticipated to be a carcinogen (Merck, 11th ed).
