Metronidazole For Poultry

Metronidazole has been used for many years in therapeutic management of trichomoniasis, giardiasis, and amebiasis. It is active against obligate anaerobic bacteria. It is not active against facultative anaerobes, obligate aerobes, or microaerophilic bacteria other than Campylobacter fetus. At concentrations readily attained in serum after PO or parenteral administration, metronidazole is active against Bacteroides fragilisB melaninogenicusFusobacterium spp, and Clostridium perfringens and ther Clostridium spp. It is generally less active against nonsporeforming, gram-positive bacilli such as ActinomycesPropionibacteriumBifidobacterium, and Eubacterium spp. Metronidazole is also somewhat less active against gram-positive cocci such as Peptostreptococcus and Peptococcus spp, but the less sensitive strains are usually not obligate anaerobes.

Metronidazole is bactericidal at concentrations equal to or slightly higher than the minimal inhibitory concentration. The precise mode of action is unclear, but reduction in an anaerobic environment yields a compound that then binds to DNA, causing loss of the helical structure, strand breakage, and impairment of DNA function. Only susceptible organisms (bacteria and protozoa) appear to be capable of metabolizing the drug.

Description

Metronidazole (brand name Flagyl®) is a synthetic, nitroimidazole antibacterial and antiprotozoal agent. It is used to treat bacterial infections caused by anaerobic bacteria (such as Clostridium), and Giardia and other gastrointestinal protozoal flagellates. Storage/Stability: Metronidazole tablets and HCl powder for injection should be stored at temperatures less than 30°C and protected from light. The injection should be protected from light and freezing and stored at room temperature.

Features of Metronidazole For Poultry

The pharmacokinetic pattern of metronidazole generally follows that expected of a highly lipid-soluble basic drug. It is readily but variably absorbed from the GI tract (bioavailability 60%–100%), with serum concentrations peaking within 1–2 hr, and becomes widely distributed in all tissues. Metronidazole penetrates the blood-brain barrier and also attains therapeutic concentrations in abscesses and in empyema fluid. It is only slightly bound to plasma proteins. Biotransformation is quite extensive, and parent drug and metabolites are excreted by both the renal and biliary routes. The elimination half-life in dogs is ~4.5 hr, and in horses, 1.5–3.3 hr.

The principal clinical indications for metronidazole include the treatment of specific protozoal infections (amebiasis, trichomoniasis, giardiasis, and balantidiasis) and anaerobic bacterial infections such as those that may be seen in abdominal abscesses, peritonitis, empyema, genital tract infections, periodontitis, otitis media, osteitis, arthritis, and meningitis, and in necrotic tissue. Metronidazole has been successfully used to prevent infection after colonic surgery. Nitroimidazoles also act as radiosensitizers, and metronidazole has been used as an adjunct to the radiotherapy of solid tumors.
