Trovafloxacin is primarily used as a broad-spectrum antibiotic to treat various bacterial infections. It is effective against both Gram-positive and Gram-negative bacteria, making it useful for respiratory tract infections, such as pneumonia, and skin and soft tissue infections. Additionally, it is employed in treating urinary tract infections and intra-abdominal infections caused by susceptible organisms. Its ability to penetrate tissues deeply allows it to address infections in hard-to-reach areas. However, due to potential severe liver toxicity, its use is restricted and reserved for serious infections where other antibiotics are ineffective or unsuitable.
