| Description | Metronidazole, also known as metrogel-vaginal or flagyl, belongs to the class of organic compounds known as nitroimidazoles. Nitroimidazoles are compounds containing an imidazole ring which bears a nitro group. Metronidazole is a moderately basic compound (based on its pKa). Metronidazole is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. |
