Product Description

Dirithromycin has an antibacterial spectrum similar to erythromycin. It has strong inhibitory effect against chlamydia and mycoplasma. For the majority of gram-positive bacilli, the activity of Dirithromycin is lower than erythromycin by 2 to 4 times. For the treatment of Bordetella pertussis, it is 4 times more active than erythromycin. Its in vitro anti-staphylococcal activity is similar to or less than erythromycin. Dirithromycin, in less than or equal to 0.03 ~ 0.12μg / ml, can inhibit Streptococcus pyogenes and Streptococcus pneumoniae. Group B Streptococci are also inhibited at the same concentration. S. pneumoniae and L. reesei were inhibited at 0.12 μg / ml and 0.5 μg / ml, respectively. Streptozotocin-resistant streptozotocin, Streptomyces A and Streptococcus are also resistant to dirithromycin. The MIC90 of sensitive- or resistant-Staphylococcus was 0.5 μg / ml and 8 μ / ml, respectively. Dirithromycin does not inhibit aerobic gram-positive bacteria. In general, dirithromycin is 2 to 4 times more active than erythromycin. The activity of erythromycin against staphylococci and streptococci is not reduced by the addition of human serum. The activity of macrolide drugs in the pH value of 8.0 is 1 to 4 times larger than that in the pH value of 6.0. Dirithromycin has a slow bactericidal effect against Staphylococcus aureus and Haemophilus influenzae. Dirithromycin is resistant to enterococci and most methicillin-resistant Staphylococcus aureus and has close cross-resistance with other macrolides.
