Methotrexate is a folate derivative that inhibits several enzymes responsible for nucleotide synthesis. This inhibition leads to suppression of inflammation as well as prevention of cell division. Because of these effects, methotrexate is often used to treat inflammation caused by arthritis or to control cell division in neoplastic diseases such as breast cancer and non-Hodgkin's lymphoma.[A180322,L7144,L7147,L7150,L7180] Due to the toxic effects of methotrexate, it is indicated for treatment of some forms of arthritis and severe psoriasis only if first line treatment has failed or patients are intolerant of those treatments. Methotrexate was granted FDA approval on 7 December 1953.
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.
