PCE ® Tablets
(erythromycin particles) in Tablets
To reduce the development of drug-resistant bacteria and maintain the effectiveness of PCE tablets and other antibacterial drugs, PCE tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.
PCE tablets (erythromycin particles in tablets) are 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 tablets are available in two strengths containing either 333 mg or 500 mg of erythromycin base. PCE tablets 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-αL-ribo-hexopyranosyl)oxy]-14-ethyl-7,12,13-trihydroxy-3,5,7,9,11,13-hexamethyl-6-[[3,4,6trideoxy-3-(dimethylamino)-β-D-xylo-hexopyranosyl]oxy]oxacyclotetradecane-2,10-dione. The molecular formula is C37H67NO13, and the molecular weight is 733.94. The structural formula is:
