Erythromycin delayed-release tablets are an antibacterial product containing erythromycin base in a specially enteric-coated tablet. The coating protects the antibiotic from the inactivating effects of gastric acidity and permits efficient absorption of the antibiotic in the small intestine. Erythromycin delayed-release tablets for oral administration are available in three dosage strengths, each white to off white oval tablet containing 250 mg, 333 mg and 500 mg of erythromycin as the free base. Erythromycin delayed-release tablets comply with USP Dissolution Test 1 .

It is basic and readily forms salts with acids. Erythromycin is a white to off-white powder, slightly soluble in water, freely soluble in alcohol and soluble in methanol. 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-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.
