[23067-13-2].» Sterile Erythromycin Gluceptate is erythromycin gluceptate suitable for parenteral use. It has a potency equivalent to not less than 600 µg of erythromycin (C37H67NO13) per mg, calculated on the anhydrous basis. In addition, where packaged for dispensing, it contains the equivalent of not less than 90.0 percent and not more than 115.0 percent of the labeled amount of erythromycin (C37H67NO13).

Assay—
Proceed as directed for erythromycin under Antibiotics—Microbial Assays 81, using an accurately weighed quantity of Sterile Erythromycin Gluceptate dissolved in methanol to yield a solution containing the equivalent of about 10 mg of erythromycin per mL. Dilute this solution quantitatively with 9 volumes of Buffer No. 3 to obtain a stock solution containing the equivalent of about 1 mg of erythromycin per mL. Where it is packaged for dispensing, constitute Sterile Erythromycin Gluceptate as directed in the labeling. Withdraw all of the withdrawable contents where the package is represented as being a single-dose container; or where the labeling specifies the amount of potency in a given volume of the resultant preparation, withdraw an accurately measured volume. Dilute quantitatively with Buffer No. 3 to obtain a stock solution having a convenient concentration. Dilute a portion of the stock solution quantitatively with Buffer No. 3 to obtain a Test Dilution having a concentration assumed to be equal to the median dose level of the Standard.
