Used primarily in the treatment of bacterial infections, especially those caused by Gram-positive bacteria. It shows strong activity against Staphylococcus and Streptococcus species, making it effective for respiratory tract infections, skin and soft tissue infections, and certain types of pneumonia. Due to its stability against beta-lactamase enzymes, it remains active against some antibiotic-resistant strains. Commonly administered in hospital settings for moderate to severe infections where penicillins may not be effective.
