Levofloxacin use prior to tuberculosis diagnosis was closely linked to antituberculosis medication resistance. Levofloxacin also reduced fluoroquinolone susceptibility after repeated use .
M. tuberculosis in the specimens showed the highest sensitivity to rifampin (97.4%) of the single antibiotic resistance tests.
Throughout the intense (6 month) and ongoing (12–18 month) phases of treatment, levoflaxacin should be administered.
One of the most widely used antibiotics, fluoroquinolones are frequently prescribed to treat respiratory tract infections . There is worry that using fluoroquinolones could delay the diagnosis of tuberculosis because they have bactericidal action against Mycobacterium tuberculosis complex.
A TB isolate is referred to be XDR-TB when it is resistant to rifampin, isoniazid, a fluoroquinolone, and an injectable antibiotic (amikacin, capreomycin, or kanamycin) . The greatest mortality and treatment failure risks are associated with XDR-TB.
Levofloxacin, given daily at a dose of 750 mg, has been shown to be as effective as moxifloxacin, taken daily at a dose of 400 mg, when used as part of an anti-MDR TB regimen. Levofloxacin also has a superior safety record than gatifloxacin and moxifloxacin.
Because dormant cells can survive in individuals with active disease and are much less vulnerable to drugs than metabolically active bacteria, scientists believe that mycobacteria are so difficult to eradicate.
Extensively drug-resistant tuberculosis (XDR TB) is a rare form of multidrug-resistant tuberculosis (MDR-TB) brought on by tuberculosis (TB) bacteria that are resistant to isoniazid, rifampin, a fluroquinolone, and a second-line injectable (amikacin, capreomycin, and kanamycin) OR by TB bacteria that are resistant to
marinum infections (8), as well as antibiotics active against atypical mycobacteria or Mycobacterium tuberculosis (isoniazid, rifabutin, ethambutol, and aminoglycosides) (clarithromycin, azithromycin, and imipenem).
Isoniazid (INH), rifapentine (RPT), or rifampin are used in LTBI treatment regimens (RIF). Short-course, rifamycin-based, 3- or 4-month latent TB infection treatment regimens are preferred over 6- or 9-month isoniazid monotherapy, according to the Centers for Disease Control and Prevention and the National Tuberculosis Controllers Association.
One-weekly isoniazid with rifapentine for three months, daily rifampin for four months, daily isoniazid plus rifampin for three to four months, and daily isoniazid for six to nine months are all recommended treatment plans for latent tuberculosis infection.
