Brodimoprim is primarily used as an antibacterial agent, particularly in the treatment of infections caused by susceptible bacteria. It is often employed in the management of respiratory tract infections, urinary tract infections, and gastrointestinal infections. Its mechanism of action involves inhibiting bacterial dihydrofolate reductase, which is crucial for bacterial DNA synthesis, thereby stopping bacterial growth. Brodimoprim is sometimes used in combination with other antibiotics to enhance its efficacy and reduce the risk of resistance development. It is also utilized in veterinary medicine for treating bacterial infections in animals.
