Daptomycin vs Teixobactin

Daptomycin vs Teixobactin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Daptomycin
Antimicrobial Peptide

Daptomycin (Cubicin) is a cyclic lipopeptide antibiotic from Streptomyces roseosporus, FDA-approved in 2003. It has a novel mechanism of action distinct from all other approved antibiotics: calcium-dependent insertion into bacterial membranes followed by channel formation and rap...
