Timely New Information on Next-Generation Tetracyclines – Part 2: Eravacycline and Protein Binding

A recent paper by Thabit describes a curious finding [1]. The authors measured total and free (i.e., nonprotein-bound) eravacycline levels at ascending doses in a mouse model. They found strikingly small increases in free drug levels when titrating up total doses. The effect was rather dramatic: an increase in protein binding from 12% Continue reading Timely New Information on Next-Generation Tetracyclines – Part 2: Eravacycline and Protein Binding

Timely New Information on Next-Generation Tetracyclines – Part 1: Omadacycline and Cardiac AEs

Several interesting articles appeared recently which shed light on the efficacy of eravacycline and the safety of omadacycline, both in Phase 3 and both in a head-to-head race to the market.  Well, the term ‘race’ is bit of a stretch as both drugs have seen very significant delays in development. Omadacycline from Continue reading Timely New Information on Next-Generation Tetracyclines – Part 1: Omadacycline and Cardiac AEs
