  • Publication number: 20220096509
    Abstract: Reformulations of gentamicin for treatment of infections are provided with the goal to reduce current side effects such as ototoxicity, while maintaining antimicrobial activity. The reformulation is a mixture of three of the C-components of gentamicin: C1a, C2a and C2b, while excluding as much as possible, C1 and C2. Specifically, to the objective of this invention a mixture is formulated having gentamicin C1a ranging from 10-30%, gentamicin C2a ranging from 0-30%, and gentamicin C2b ranging from 40-90%, where the mixture totals a 100% of the gentamicin C-components, defined as C1, C1a, C2, C2a and C2b only. The formulations of this invention increase the probability of a more favorable outcome for the patients exposed to gentamicin, i.e., reduced risk of the side-effect of hearing loss.
