| Hazard Information | Back Directory | [Definition]
ChEBI: A hydrochloride salt resulting from the mixture of equimolar amounts of metronidazole and hydrogen chloride. | [Uses]
Metronidazole hydrochloride (SC 326421) is an orally active nitroimidazole antibiotic, can be used to research anaerobic infections. Metronidazole hydrochloride can cross blood brain barrier and results inflammation and skeletal muscle contraction under long-term application[1][2][3][4]. | [in vivo]
Metronidazole hydrochloride (135 mg/kg/d; p.o.; 28 d) can cross the blood brain barrier, and exhibits neurotoxicity under long term administration in rats[3].
Metronidazole hydrochloride (1 g/L; p.o.; 4 weeks) results skeletal muscle atrophy and changes the expression of genes involved in the muscle peripheral circadian rhythm machinery and metabolic regulation[4].
| Animal Model: | Sprague-Dawley (SD) rats (200-220 g)[3] | | Dosage: | 135 mg/kg | | Administration: | Oral gavage; once daily; 28 days | | Result: | Caused inflammatory markers increasing, including iNOS, eNOS, Bax and caspase 3 protein expressions increasing and caused oxidative stress damage in brain tissue, with MDA content rising.
|
| Animal Model: | SPF C57Bl/6J mice (6-7 months old)[4] | | Dosage: | 1 g/L (full dose) | | Administration: | Oral gavage; provided with drinking water for 4 weeks, changed twice weekly | | Result: | Resulted the muscle core clock and effector genes Cry2, Ror-β, E4BP4, PP ARγ and adiponectin expression increasing.
Decreased hind limb muscle weight and resulted in smaller fibers in the tibialis anterior muscle.

| Chemical Properties | Back Directory | [Contact allergens]
Metronidazole is a nitro-5-imidazole compound with antiprotozoal and antibacterial properties. Topical exposure may induce allergic contact dermatitis. Sensitization is mainly observed with the treatment of rosacea and rarely occurs from handling of tablets in nurses. Systemic intake may provoke fixed drug eruption. |
