All mycoplasmas lack a cell wall and, therefore, all are inherently resistant to beta-lactam antibiotics (e.g., penicillin). Clinicians treat the disease with macrolide, tetracycline, or fluoroquinolone classes of antibiotics, taking age of the patient and local antibiotic resistance patterns into consideration: Clinicians should not prescribe fluoroquinolones and tetracyclines for young children under normal circumstances. Macrolides are generally considered the treatment of choice. However, clinicians should practice prudent use of macrolide drugs due to the emergence of macrolide-resistant strains of since 2000. This issue is especially troubling in Asia, where resistance rates have been as high as 90%. The United States and Europe have also reported macrolide resistance. Current data suggest that the prevalence of macrolide resistance in is probably rising in the United States. buy zovirax cream (acyclovir From 2 of 13 men with urethritis in 1980  led to a number of attempts to associate the bacterium with urogenital tract disease, but, because of the lack of specific and sensitive detection methods, many of the efforts were futile. It was not until the advent of polymerase chain reaction methods 10 years later  that clinical studies became feasible, and it took another 10 years to prove unequivocally that , it partly filled a gap in our understanding of nonchlamydial NGU, explaining 20%–35% of these cases. Although initial in vitro studies suggested that antibiotics of the tetracycline class were active, clinical experience soon demonstrated their inefficiency in producing both microbiologic and clinical cure. Several small observational studies as well as a recent larger study from Scandinavia  demonstrated that less than half of infections were cured after doxycycline treatment, whereas azithromycin given as a single 1-g dose cured 80%–85% of the infections and azithromycin given at an extended dosage of 500 mg on day 1 followed by 250 mg daily on days 2–5 cured , and all those treated with the 5-day course of azithromycin were cured. In contrast, when patients experience treatment failure with a 1-g single dose of azithromycin, the extended 5-day course of azithromycin appears to be much less efficient, as demonstrated by a cure rate as low as 34% among 23 patients in a recent study . The finding that failure of azithromycin treatment as well as in vitro resistance to macrolide antibiotics is caused by single-base mutations in the 23S r RNA gene and that these mutations most often occur as a result of treatment with a single 1-g dose of azithromycin  is an obvious explanation for this observation. In patients experiencing failure of both doxycycline and the 5-day azithromycin regimen, moxifloxacin given at 400 mg daily for 7 or 10 days seems to be the only efficient treatment option .

Macrolides e.g. azithromycin Children and adults; Fluoroquinolones Adults. Azithromycin, as the dihydrate, is a white crystalline powder with a molecular formula of C 38 H 72 N 2 O 12 •2H 2 O and a molecular weight of 785.0. ZITHROMAX tablets contain azithromycin dihydrate equivalent to 600 mg azithromycin. Oral erythromycin or one of the newer macrolides such as azithromycin or clarithromycin have long been the DOC for mycoplasmal respiratory tract infections. Clindamycin is effective in vitro, but limited reports suggest it may not be active in vivo and thus is not considered a first-line treatment. Fluoroquinolones such as levofloxacin or moxifloxacin exhibit bactericidal antimycoplasmal activity but are generally less potent in vitro than macrolides against species are slow-growing organisms that have the capacity to reside intracellularly; thus, respiratory tract infections are expected to respond better to longer treatment courses than might be offered for other types of infections. Although physicians typically prescribe most treatment regimens (ie, both oral and parenteral) for 7-10 days, a 14- to 21-day course of oral therapy with most agents is also appropriate. A 5-day course of oral azithromycin is approved for the treatment of community-acquired pneumonia. Clinical data indicate that this duration of treatment is of comparable efficacy to a 10-day course of erythromycin. Other drugs, including fluoroquinolones, have been approved for the treatment of mycoplasmal respiratory infections with shorter courses because of their favorable pharmacokinetics and tolerability. infections, other measures (eg, cough suppressants, antipyretics, analgesics) should be administered as needed to relieve headaches and other systemic symptoms. Treatment studies using azithromycin 1 g single dose and azithromycin 500 mg on day 1 then 250 mg daily for 4 days (5-day regimen) to determine rates of treatment failure and resistance in both regimens. Studies were eligible if they: used azithromycin 1 g or 5 days, assessed patients for macrolide resistant genetic mutations prior to treatment and patients who failed were again resistance genotyped. Random effects meta-analysis was used to estimate failure and resistance rates. Results Eight studies were identified totalling 435 patients of whom 82 (18.9%) had received the 5-day regimen. The random effects pooled rate of treatment failure and development of macrolide antimicrobial resistance mutations with azithromycin 1 g was 13.9% (95% CI 7.7% to 20.1%) and 12.0% (7.1% to 16.9%), respectively. Of individuals treated with the 5-day regimen, with no prior doxycycline treatment, fewer (3.7%; 95% CI 0.8% to 10.3%, p=0.012) failed treatment, all of whom developed resistance (p=0.027).
