🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two antimicrobial agents. Furazolidone is reduced by bacterial and protozoal enzymes to reactive intermediates that damage DNA and other macromolecules, leading to cell death. Metronidazole enters susceptible organisms and is reduced by ferredoxin-like electron transport proteins to nitro radical anions, which cause DNA strand breakage and inhibit nucleic acid synthesis. The combination provides broad coverage against certain protozoa and bacteria.
Mechanism Steps
💡 How to Take anaerid-f 100mg/300mg tablet
Strength: Each tablet contains furazolidone 100 mg and metronidazole 300 mg.
Dosage Information
| Adult Dosage | The usual adult dose is one tablet taken orally two to three times daily, depending on the infection being treated. The exact dose and duration must be individualized by a qualified clinician based on the indication, severity of infection, age, weight, renal and hepatic function. Do not self-adjust the dose. Complete the full course as prescribed. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing. |
| Elderly Dosage | Elderly patients may be more susceptible to side effects such as peripheral neuropathy and dizziness. Dose adjustment may be necessary based on renal and hepatic function. Use with caution and monitor closely. |
| Renal Impairment | In patients with severe renal impairment, metronidazole may accumulate. Dose adjustment may be required. Consult a doctor for individualized dosing. |
| Hepatic Impairment | In patients with severe hepatic impairment, dose reduction may be necessary due to reduced metabolism of metronidazole. Use with caution and monitor liver function. |
| Maximum Daily Dose | The maximum daily dose should not exceed the prescribed amount. Typically, the maximum is 3 tablets per day, but this must be determined by a qualified clinician. |
