(S)-Tedizolid is primarily used as an antibiotic to treat serious bacterial infections, particularly those caused by Gram-positive bacteria. It is especially effective against infections like acute bacterial skin and skin structure infections (ABSSSI), including those caused by methicillin-resistant Staphylococcus aureus (MRSA). Its application is crucial in cases where other antibiotics have failed due to resistance. The compound works by inhibiting bacterial protein synthesis, thereby stopping the growth and spread of the infection. It is often administered intravenously or orally, providing flexibility in treatment options for patients with varying degrees of infection severity. Its targeted mechanism of action and potency make it a valuable tool in combating resistant bacterial strains in clinical settings.
