The fluoroquinolones are also listed in the Merck Manual as chemotherapeutic agents.

The WP:MTAA which you referred to as justification of your edit also states that articles are not to be dumbed down either when they are technical in nature.  And a drug article, by  its very nature, is a technical article.  Another issue appears to be that you are unaware that this class has been shown to be toxic to mammalian cells in culture.  Inadvertent DNA damage is a very real possibility with this class resulting in collateral damage to the patient.  I would suggest that reading the DNA section found within the Adverse effects of the fluoroquinolones may help to familiarize you with this aspect.  Such DNA damage has also been confirmed in animal models as well.
