Eravacycline: a comprehensive review of in vitro activity, clinical efficacy, and real-world applications.

ABSTRACT

INTRODUCTION: The escalating threat of multidrug-resistant organisms necessitates constant exploration for novel antimicrobial agents. Eravacycline has emerged as a promising solution due to its unique chemical structure, which enhances potency and expands its spectrum of activity. AREA COVERED This review provides a thorough examination of eravacycline, encompassing its in vitro activity against Gram-positive and Gram-negative aerobes, carbapenem-non-susceptible organisms, anaerobes, and other bacterial strains. Additionally, it evaluates evidence from clinical studies to establish its clinical effect and safety. EXPERT OPINION Eravacycline, a synthetic fluorocycline, belongs to the tetracyclines class. Similar to other tetracycline, eravacycline exerts its antibacterial action by reversibly binding to the bacterial ribosomal 30S subunit. Eravacycline demonstrates potent in vitro activity against many Gram-positive and Gram-negative aerobes, anaerobes, and multidrug-resistant organisms. Randomized controlled trials and its associated meta-analysis affirm eravacycline's efficacy in treating complicated intra-abdominal infections. Moreover, real-world studies showcase eravacycline's adaptability and effectiveness in diverse clinical conditions, emphasizing its utility beyond labeled indications. Despite common gastrointestinal adverse events, eravacycline maintains an overall favorable safety profile, reinforcing its status as a tolerable antibiotic. However, ongoing research is essential for refining eravacycline's role, exploring combination therapy, and assessing its performance against biofilms, in combating challenging bacterial infections.
