PCE (erythromycin particles in tablets) is an antibacterial product containing
specially coated erythromycin base particles for oral administration. The coating
protects the antibiotic from the inactivating effects of gastric acidity and
permits efficient absorption of the antibiotic in the small intestine. PCE (erythromycin pce (erythromycin pce) ) is
available in two strengths containing either 333 mg or 500 mg of erythromycin
base. PCE (erythromycin pce (erythromycin pce) ) 500 mg tablets contain no synthetic dyes or artificial colors.
Erythromycin is produced by a strain of Saccharopolyspora erythraea
(formerly Streptomyces erythraeus) and belongs to the macrolide group
of antibiotics. It is basic and readily forms salts with acids. Erythromycin
is a white to off-white powder, slightly soluble in water, and soluble in alcohol,
chloroform, and ether. Erythromycin is known chemically as (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-ethyl7,12,13-trihydroxy-3,5,7,9,11,13-hexamethyl-6-[[3,4,6-trideoxy-3-(dimethylamino)-β-D-xylohexopyranosyl]oxy]oxacyclotetradecane-2,10-dione.
The molecular formula is C37H67NO13, and the molecular weight is 733.94. The
