Research is being conducted on combination therapies to combat drug-resistant pathogens, with a focus on fosfomycin paired with other antibiotics. Some studies are exploring the in vitro effectiveness of fosfomycin combined with antibiotics such as amoxicillin, daptomycin, and linezolid against certain bacterial strains. The scope of this research appears to encompass various types of bacteria and potential treatments for infections, including those related to urinary tract issues.
