erythromycin - Generic Medications

Erythromycin Ophthalmic Ointment belongs to the macrolide group of antibiotics. It is basic and readily forms a salt when combined with an acid. The base, as crystals or powder, is slightly soluble in water, moderately soluble in ether, and readily soluble in alcohol or chloroform. 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-(dimethyl-amino)-β-D- xylo -hexopyranosyl]oxy]oxacyclotetradecane-2,10-dione)) is an antibiotic produced from a strain of Streptomyces erythraeus. It has the following structural formula: Each gram contains Erythromycin USP 5 mg in a sterile ophthalmic base of mineral oil and white petrolatum. Structural Formula

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 . 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, 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. The molecular formula is C 37 H 67 NO 13 , and the molecular weight is 733.93. The structural formula is: chemical-structure Inactive Ingredients Calcium silicate, colloidal silicon dioxide, croscarmellose sodium, hydroxypropyl cellulose, hypromellose, magnesium stearate, mannitol, methacrylic acid and ethyl acrylate copolymer, poloxamer 407, polyethylene glycol, pregelatinized maize starch, sodium bicarbonate, sodium citrate, sodium lauryl sulphate, talc and titanium dioxide.

Erythromycin, USP 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. The base, the stearate salt, and the esters are poorly soluble in water. Erythromycin ethylsuccinate, USP is an ester of erythromycin, USP suitable for oral administration. Erythromycin ethylsuccinate, USP is known chemically as erythromycin 2'-(ethyl succinate). The molecular formula is C 43 H 75 NO 16 and the molecular weight is 862.05 g/mol. The structural formula is: Erythromycin ethylsuccinate for oral suspension, USP, 200 mg/5 mL when reconstituted with water, forms a suspension containing erythromycin ethylsuccinate, USP equivalent to 200 mg erythromycin per 5 mL (teaspoonful) or 100 mg per 2.5 mL (dropperful) with an appealing fruit flavor. Erythromycin ethylsuccinate for oral suspension, USP, 400 mg/5 mL when reconstituted with water, forms a suspension containing erythromycin ethylsuccinate, USP equivalent to 400 mg of erythromycin per 5 mL (teaspoonful) with an appealing banana flavor. These products are intended primarily for pediatric use but can also be used in adults. Inactive Ingredients Erythromycin ethylsuccinate for oral suspension, USP, 200 mg/5 mL contains caramel flavor, mixed fruit flavor, polysorbate 80, sodium citrate dihydrate, sucrose, and xanthan gum.
