Tedizolid for treatment of acute bacterial skin and skin structure infections

Tedizolid is a newly approved drug of the oxazolidinone class. It has high in vitro activity against Gram-positive bacteria, including multidrug-resistant strains. Peak plasma concentration of tedizolid is obtained within 3 h of oral dosing (PO), with high bioavailability. Tedizolid is mostly metabolized via the liver, and is excreted in feces in the form of a sulfate conjugate. Tedizolid 200 mg taken once daily demonstrated non-inferior efficacy and a good safety profile in patients with acute bacterial skin and skin structure infections. Results of two pivotal Phase III clinical trials showed that 6 days of 200 mg tedizolid PO or sequential intravenous (IV)/PO once-daily treatment was non-inferior to 10 days of 600 mg linezolid PO or sequential IV/PO twice-daily treatment at 48-72 h (primary end point) and at the test-of-cure in patients with acute bacterial skin and skin structure infections. The Phase II and Phase III trials also demonstrated that tedizolid was well tolerated.
