Quinolone, Levaquin (levofloxacin)
You'll see another quinolone, Levaquin (levofloxacin)... from Janssen-Ortho.
It's not really new...it's the levo isomer of ofloxacin. Ofloxacin (Floxin) is a mixture of both levo and dextro isomers.
The levo isomer is responsible for most of the antibacterial effect. This means that levofloxacin is about TWICE as active as ofloxacin at the same dose.
