Finafloxacin is a fluoroquinolone antimicrobial agent that exhibits optimum efficacy in slightly acidic environments and is a highly potent eradicator of Helicobacter pylori. Being developed to treat serious bacterial infections associated with an acidic environment, including urinary tract infections and Helicobacter pylori infections finafloxacin is approved for treatment of acute otitis externa (swimmer’s ear) caused by the bacteria Pseudomonas aeruginosa and Staphylococcus aureus. XTORO (finafloxacin otic suspension), 0.3% is supplied as a sterile, preserved, aqueous suspension. Finafloxacin is a drug with a favorable safety profile.

Amoxicillin is one of the widely prescribed antibacterial agents, which was discovered by scientists at Beecham Research Laboratories in 1972. In the US GlaxoSmithKline markets it under the original brand name Amoxil. It is the first line treatment for middle ear infections. It is also used for strep throat, pneumonia, skin infections, and urinary tract infections it is taken by mouth. Amoxicillin inhibits the third and final stage of bacterial cell wall synthesis by preferentially binding to specific penicillin-binding proteins (PBPs) that are located inside the bacterial cell wall. This results in a formation of defective cell wall and a cell death. Common side effects include nausea and rash. It may also increase the risk of yeast infections and, when used in combination with clavulanic acid, diarrhea. It should not be used in those who are allergic to penicillin.
