Widely used to treat bacterial infections such as respiratory tract infections, skin infections, and sexually transmitted diseases like chlamydia. Effective against a broad range of bacteria due to its ability to accumulate in tissues and provide sustained action. Commonly prescribed for mild to moderate infections when a short treatment course is preferred. Also used in prophylaxis for certain infections in immunocompromised patients. Its long half-life allows for once-daily dosing and shorter treatment durations compared to other antibiotics.
