Torezolid Usage And Synthesis
  • Novel antibacterial drugsTedizolid belongs to the second generation oxazolidinone antibiotics, being an analog of linezolid as well as a kind of protein synthesis inhibitors, acting on the bacterial ribosomal 50S subunit and causing inhibition of bacterial protein synthesis. Compared with linezolid, the efficacy of the two is basically the same, but linezolid required to be taken for 2 times a day and for 10 continuous days while Tedizolid only takes 1 time daily and continuous taking for 6 days.
    On June 20, 2014, the US FDA had approved a new antimicrobial drug Tedizolid (trade name: Sivextro) for the treatment of skin infections in adult patients. Sivextro is approved for the treatment of acute bacterial skin and skin infections caused by certain sensitive bacteria such as Staphylococcus aureus (including methicillin-resistant strains and methicillin-sensitive strains), various streptococci and Enterococcus faecalis (ABSSSI). Sivextro is administered intravenously and orally.
    Tedizolid phosphate is a second-generation oxazolidinone antibiotic developed by Dong-A Pharmaceutical, licensed to Cubist Pharmaceuticals and Bayer for commercial development.
    Sivextro is designed for the treatment of serious or life-threatening infections, and its listing applications are eligible for Qualified Infectious Disease Products (QIDP) and have obtained the approve of FDA for accelerated review. Sivextro's QIDP eligibility gives the drug exclusive five-year market exclusivity, in addition to its market exclusivity under the Food, Drug, and Cosmetic Act.
    The safety and efficacy of Sivextro were evaluated in two clinical trials involving 1315 ABSSSI adult patients. Subjects were randomized to Sivextro or another antibiotic linezolid approved for the treatment of acute bacterial skin and skin structure infections (ABSSSI). The results showed that its clinical efficacy is equivalent to linezolid. However, it will cause less gastrointestinal adverse reactions and thrombocytopenia adverse reactions than linezolid. The incidence of drug resistance is also lower. Tedizolid has been shown to be more tolerant than vancomycin.
    The most common side effects identified in clinical trials include nausea, headache, diarrhea, vomiting and dizziness. The safety and efficacy of Sivextro have not been evaluated in patients with reduced white blood cell levels (neutropenia), so alternative therapies should be considered for these patients. Sivextro is marketed by Cubist Pharmaceuticals, Inc., based in Lexington, Massachusetts.
    Status of intellectual property: Compound patent ZL200480037612.2, protection period 2024.12.17 expires.
