Ciprofloxacin lactate is used to treat a wide range of serious bacterial infections, including respiratory tract infections (such as certain types of pneumonia), urinary tract infections, skin and soft tissue infections, gastrointestinal infections, bloodstream infections, and bone infections. It is effective primarily against gram-negative bacteria and some gram-positive bacteria. Commonly prescribed when other antibiotics fail due to resistance. The lactate form is administered intravenously, making it suitable for hospitalized patients, particularly those unable to take oral medications. It is valued for its broad-spectrum activity and rapid onset of action.
