Pharmacology
Metronidazole could be a part of the imidazole lesson of antibacterial sedate and is classified remedially as an antiprotozoal specialist. The 5-nitro gather of Metronidazole is diminished by anaerobes metabolically. Thinks have illustrated that the decreased shape of this medicate interatomic with DNA and gives the bactericidal activity of Metronidazole.
