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. The base, the stearate salt, and the esters are poorly soluble in water. Erythromycin ethylsuccinate is an ester of erythromycin suitable for oral administration. Erythromycin ethylsuccinate is known chemically as erythromycin 2'-(ethylsuccinate). The molecular formula is C 43 H 75 NO 16 and the molecular weight is 862.06. The structural formula is: Erythromycin Ethylsuccinate Granules are intended for reconstitution with water. Each 5-mL teaspoonful of reconstituted cherry-flavored suspension contains erythromycin ethylsuccinate equivalent to 200 mg of erythromycin. The pleasant tasting, fruit-flavored liquids are supplied ready for oral administration. Erythromycin Ethylsuccinate 200 Liquid: Each 5-mL teaspoonful of fruit-flavored suspension contains erythromycin ethylsuccinate equivalent to 200 mg of erythromycin. Erythromycin Ethylsuccinate 400 Liquid: Each 5-mL teaspoonful of orange-flavored suspension contains erythromycin ethylsuccinate equivalent to 400 mg of erythromycin. Granules and ready-made suspensions are intended primarily for pediatric use but can also be used in adults. Chemical Structure Inactive Ingredients Erythromycin Ethylsuccinate Granules: Citric acid, FD&C Red No. 3, magnesium aluminum silicate, sodium carboxymethylcellulose, sodium citrate, sucrose and artificial flavor.
