DESCRIPTION
Erythromycin Topical Gel USP, 2% contains erythromycin (3R*, 4S*, 5S*,
6R*, 7R*, 9R*, 11R*, 12R*,
13S*,
14R*)-4-[(2,6-Dideoxy-3-_C_-methyl-3-_O_-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)-β-D-_xylo_-
hexopyranosyl]oxy]oxacyclotetradecane-2,10-dione), for topical
dermatological use. Erythromycin is a
macrolide antibiotic produced from a strain of _Saccaropolyspora
erythraea_ (formerly _Streptomyces_
_erythreus_). It is a base and readily forms salts with acids.
Chemically, erythromycin is C
H NO . It has the following structural formula:
Erythromycin has a molecular weight of 733.94. It is a white or
slightly yellow, odorless or practically
odorless, bitter crystalline powder. Erythromycin is very soluble in
very polar organic solvents such as
alcohols, acetone, chloroform, acetonitrile and ethyl acetate. It is
moderately soluble in less polar
solvents such as ether, dichloroethylene and amyl acetate. It is
slightly soluble in nonpolar solvents
such as hexane. It is very poorly soluble in water.
Each gram of Erythromycin Topical Gel USP, 2% contains 20 mg of
erythromycin USP in a vehicle
consisting of dehydrated alcohol and hydroxypropyl cellulose.
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.
