Terizidone is a chemotherapeutic agent for oral administration, which has a bacteriostatic effect and a wide spectrum of action.
Terizidone is effective against Mycobacterium tuberculosis, Mycobacterium bovis, Mycobacterium avium, and Staphylococcus aureus and Staphylococcus epidermis. To this preparation are also sensitive Enterococcus faecalis, Escherichia coli, Citrobacter, Enterobacter, Morganella morganii, Klebsiella pneumonia and Pseudomonas aeruginosa.
The level of the minimal effect of the initial concentration for mycobacteria is 10-40 mg / l, for staphylococci 8 - 32 mg / l, and for gramogens bacteria of clinical significance 50 - 250 mg / l.
The sensitivity of mycobacteria exceeds 90 %. The sensitivity of other bacteria in some cases varies considerably and is established only for staphylococci (more than 90%) and Streptococcus faecalis (81 %),
The development of secondary resistance is rare. Between trisidone and other anti-tuberculosis drugs there is no cross-resistance.
