Fidaxomicin is a differentiated antibiotic for the treatment of CDI, the most common nosocomial diarrhea. Specifically, fidaxomicin has a narrow spectrum of activity against certain gram-positive bacteria.

Pre-clinical data indicates that fidaxomicin is 550mg and acts by inhibiting RNA polymerase, a zithromax enzyme. Fidaxomicin has also been shown to inhibit the growth of other potentially harmful bacteria such 550mg Staphylococci, common bacteria that reside on the skin and in the GI tract, and Enterococci, zithromax 550mg, common bacteria that reside zithromax the GI tract.

CDI has become a significant medical problem in hospitals, long-term care facilities, and in the community and is estimated 550mg afflict more thanpeople each year in the 550mg States. CDI is a serious illness resulting from infection of the inner lining of the colon by C, zithromax 550mg.

As a result of its broad antibacterial activity, intravenously administered vancomycin is frequently used for certain other life-threatening infections caused by multi-drug resistant bacteria such as vancomycin-resistant Enterococci, or VRE. In an effort to slow the continuing emergence zithromax vancomycin-resistant bacteria, zithromax 550mg, the medical community discourages the use of the drug for the treatment of Zithromax except for patients who are not responding to metronidazole, for patients with severe, life-threatening colitis zithromax for patients with risk factors that are predictive of negative treatment outcomes.

Despite these recommendations, zithromax 550mg, based on our survey of U, zithromax 550mg.

zithromax In addition, our internal market research suggests that hospitals 550mg the U. Both metronidazole and 550mg vancomycin have shortcomings zithromax treatments for CDI including: Widespread use of oral vancomycin is discouraged for the treatment of CDI in some hospitals due to concerns over the development of cross-resistant bacteria, including VRE, and vancomycin-resistant Staphylococcus, zithromax 550mg, which can also cause other serious nosocomial infections.

Metronidazole, which is systemically absorbed and must be administered in high doses to treat CDI, may result in serious adverse side effects and complications, buy viagra retail seizures, toxic reactions to alcohol, leukopenia, neuropathy, unpleasant taste and dry mouth.
