A member of the semi-synthetic macrolide class of antibiotics, roxithromycin is employed in infections of the respiratory tract, urinary, and soft tissue infections. Its macrocyclic lactone ring and deoxy sugars, defining features of macrolide antibiotics, mediates its mechanism of action as it inhibits peptide translocation by binding to the 50S subunit of the bacterial ribosome. Protein synthesis is thus inhibited by ribosomal binding. It has been demonstrated to have a longer half-life compared to other macrolide antibiotics such as erythromycin and is effective against certain Gram-negative bacteria.
