Ornidazole is primarily used as an antiprotozoal and antibacterial medication. It is effective in treating infections caused by anaerobic bacteria and certain parasites. Commonly, it is prescribed for conditions such as amoebiasis, giardiasis, and trichomoniasis. It is also utilized in the prevention and treatment of infections following surgical procedures, particularly in the gastrointestinal and pelvic regions. Additionally, Ornidazole is employed in veterinary medicine to manage similar infections in animals. Its ability to penetrate tissues and body fluids makes it a reliable option for combating deep-seated infections.
