Development and Validation of a Novel RP-HPLC Method for Simultaneous Quantification of Erythromycin and Isotretinoin in Tablet Formulations
Introduction Erythromycin, a macrolide antibiotic produced by Streptomyces erythraea, functions as an antibacterial agent effective against various bacterial infections. Chemically, Erythromycin is characterized as 6-{[(2S,3R,4S,6R)-4-(dimethylamino)-3-hydroxy-6-methyloxan-2-yl]oxy}-14-ethyl-7,12,13-trihydroxy-4-{[(2R,4R,5S,6S)-5-hydroxy-4-methoxy-4,6-dimethyloxan-2-yl]oxy}-3,5,7,9,11,13-hexamethyl-1-oxacyclotetradecane-2,10-dione (C37H67NO13, molecular weight 733.92 g/mol). Its mechanism of action involves inhibition of bacterial protein synthesis by binding to the 50S ribosomal subunit, thereby inhibiting peptidyl …
