Zithromax is a semi-synthetic antibiotic, the first representative of a subclass called azalides and slightly different in structure from the classical macrolides. The mechanism of action of Azithromycin is associated with its effect on the function of bacterial ribosomes. High concentration of Zitrhomax in infected tissues is also caused by the fact that phagocytes and macrophages transport it to the site of infection and release in the area of inflammation.Bonness Oilfield is owned and operated by Mark Bonnett and Derek Ness.
