Loratadine Combats Methicillin-Resistant by Modulating Virulence, Antibiotic Resistance, and Biofilm Genes.

Methicillin-resistant (MRSA) has evolved to become resistant to multiple classes of antibiotics. New antibiotics are costly to develop and deploy, and they have a limited effective lifespan. Antibiotic adjuvants are molecules that potentiate existing antibiotics through nontoxic mechanisms.
