What are the side effects of Erythromycin?

Aug 19，2024

Introduction

Erythromycin is a conventional antibiotic that binds bacterial ribosomes and inhibits protein synthesis. This bacteriostatic mode of action inhibits the replication (growth) of bacteria during infection. Erythromycin, a medically necessary antibiotic, was discovered in 1952 in the actinobacterium Streptomyces erythreus (renamed Saccharopolyspora erythraea in 1987). This microbe then became the biosynthesizer for the industrial production of Erythromycin, a practice that remains to this day.

History

Erythromycin, the first-generation macrolide antibiotic, was founded by Eli Lilly Corporation. As Erythromycin has a low bioavailability and it’s poor tolerance, Taisho Pharmaceutical developed the second generation macrolide antibiotic-Clarithromycin. At this time, Taisho Pharmaceutical transferred the possession of Clarithromycin to Abbott Laboratories. In 1998, Hoeehst-Roussell successfully developed another macrolide antibiotic-Roxithromycin. In the treatment of infectious diseases, pharmaceutics of Erythromycin, Clarithromycin, Roxithromycin, and Azithromycin are widely used in clinics. At same time, because we frequently use Erythromycin antibiotics or abuse causing bad results of un-tolerance. Now, pharmacologists are devoted to developing new-generation macrolide antibiotics, which have better therapeutic effects and are more tolerant to bacteria[1].
