readily forms salts with
acids. Chemically, erythromycin is:
(3_R_*,4_S_*,5_S_*,6_R_*,7_R_*,9_R_*,11_R_*,12_R_*,13_S_*,14_R_*)-4-
[(2,6-Dideoxy-3-_C_-methyl-3-_0_-methyl-α-L-_ribo_-hexopyranosyl)oxy]-14-ethyl-7,12,13-
trihydroxy
-3,5,7,9,11,13-hexamethyl-6-[[3,4,6-trideoxy-3-(dimethylamino)-ß-D-_xylo_-
hexopyranosyl]oxy]oxacyclotetradecane-2,10-dione. It has the following

CLINICAL PHARMACOLOGY
The exact mechanism by which erythromycin reduces lesions of acne
vulgaris is not fully
known; however, the effect appears to be due in part to the
antibacterial activity of the
drug.
MICROBIOLOGY –
Erythromycin acts by inhibition of protein synthesis in susceptible
organisms by
reversibly binding to 50S ribosomal subunits, thereby inhibiting
translocation of
aminoacyl transfer-RNA and inhibiting polypeptide synthesis.
Antagonism has been
demonstrated _in vitro _between erythromycin, lincomycin,
chloramphenicol, and
clindamycin.
