Levofloxacin is a fluoroquinolone antibiotic and the optical S-(-) isomer of racemic [ofloxacin]. It reportedly carries 8 to 128-fold more activity against both gram-negative and gram-positive bacteria compared to R-(+)-ofloxacin and remains stereochemically stable following administration (i.e. it does not invert to the inactive isomer). Levofloxacin, along with other quinolones such as [gatifloxacin] and [moxifloxacin], is a member of the third generation of fluoroquinolones, colloquially referred to as the "respiratory quinolones" due to improved activity against gram-positive bacteria commonly implicated in respiratory infections.[A31453,A190756] Levofloxacin was first approved by the FDA in 1996, and was approved in Canada and several South American countries soon after.
Valbenazine is a modified metabolite of [tetrabenazine], and it is currently being approved for the treatment of various movement disorders, particularly tardive dyskinesia and chorea associated with Huntington's disease.[L47885,A261135] Tardive dyskinesia has long been regarded as a consequence of anti-dopamine receptor therapy, and until 2008 with the advent of [tetrabenazine], most treatments were ineffective. However, challenges in using [tetrabenazine] as a treatment of tardive dyskinesia included frequent dosing and safety and tolerability concerns. On April 2017, valbenazine was approved by the FDA under the brand name INGREZZA as the first and only approved treatment for adults with Tardive Dyskinesia (TD). On August 2023, valbenazine was again approved by the FDA for the treatment of chorea associated with Huntington's disease respectively. This approval was supported by positive results in multiple trials, including the KINECT-HD Phase 3 study and the ongoing KINECT-HD2 open-label extension trial. The reduction in chorea severity was observed as early as 2 weeks after starting treatment with an initial dose of 40 mg.
