Tedizolid free base is primarily used as an antibiotic to treat serious bacterial infections, particularly those caused by Gram-positive bacteria. It is effective against infections such as acute bacterial skin and skin structure infections (ABSSSI), including those caused by methicillin-resistant Staphylococcus aureus (MRSA). The compound works by inhibiting bacterial protein synthesis, thereby stopping the growth and spread of bacteria. Its application is especially valuable in cases where patients have shown resistance to other antibiotics, offering a potent alternative with a favorable safety profile. Tedizolid is often administered in a hospital setting for patients requiring intravenous or oral treatment, ensuring targeted and effective management of severe infections.
