Astemizole is a long-acting, non-sedating second generation antihistamine used in the treatment of allergy symptoms. It was withdrawn from market by the manufacturer in 1999 due to the potential to cause arrhythmias at high doses, especially when when taken with CYP inhibitors or grapefruit juice.
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.
