Metronidazole (Pliva 334) Common Medical Uses
Metronidazole, often identified by the imprint "Pliva 334," is a widely used antibiotic and antiprotozoal medication. It is primarily prescribed for treating infections caused by anaerobic bacteria and certain parasites. Common uses include the treatment of trichomoniasis, amoebiasis, giardiasis, and infections caused by Bacteroides, Fusobacteria, and Clostridia species. It is also used for gynecologic infections, endocarditis, septicemia, respiratory tract infections, and as a prophylactic agent before surgical procedures to prevent infection. Additionally, metronidazole is used in the management of Crohn’s disease and various oral and dental infections, such as acute ulcerative gingivitis, pericoronitis, and some cases of osteomyelitis and infected dental sockets 1234710.
Metronidazole in Dental and Periodontal Infections
In dentistry, metronidazole is valued for its effectiveness against obligate anaerobic bacteria, which are often implicated in oral diseases. It is specifically used to treat acute ulcerative gingivitis, pericoronitis, certain periapical infections, and some cases of osteomyelitis. It may also be helpful in chronic progressive periodontitis where anaerobes are major pathogens. Metronidazole’s targeted action against anaerobes means it does not disturb the normal aerobic flora, and resistance is rare 25.
Metronidazole for Gastrointestinal and Parasitic Infections
Metronidazole remains the drug of choice for treating various gastrointestinal infections, including those caused by Clostridium difficile and Helicobacter pylori (as part of combination therapy). It is also effective against parasitic infections such as trichomoniasis, amoebiasis, and giardiasis. Its use in treating Helicobacter pylori is sometimes limited by resistance, but new formulations and combination therapies are being explored to overcome this issue 3478.
Anti-Inflammatory Properties and Other Uses
Emerging evidence suggests that metronidazole may have anti-inflammatory effects, particularly in the treatment of periodontitis. Studies indicate that it can influence both innate and acquired immune responses, as well as promote wound healing and resolution of inflammation. It has also been shown to reduce intestinal inflammation and blood loss in patients with NSAID-induced enteropathy, likely by targeting metronidazole-sensitive microbes involved in the inflammatory process 56.
Safety, Side Effects, and Prescribing Practices
Metronidazole is generally well tolerated, with most side effects being mild to moderate, such as nausea, abdominal pain, and diarrhea. Rare but serious side effects include neurotoxicity, optic neuropathy, peripheral neuropathy, and encephalopathy. Its use is sometimes restricted in veterinary medicine due to concerns about tumor risk. In clinical practice, metronidazole is often prescribed for surgical prophylaxis, diverticulitis, and aspiration pneumonia, but studies have highlighted the need for improved guideline compliance and appropriate use, as it is sometimes prescribed when its spectrum is unnecessarily broad 1710.
Conclusion
Metronidazole (Pliva 334) is a versatile and widely used medication for treating anaerobic bacterial and certain parasitic infections. Its applications span from dental and gastrointestinal infections to surgical prophylaxis and potential anti-inflammatory uses. While generally safe, careful prescribing and awareness of potential side effects are important to ensure optimal patient outcomes and minimize resistance.
