This is not a complete List of Quinolones and Fluoroquinolones that have been in existence. There are thousands of quinolones and related drugs, often with different generic names for the same drug, so be aware of the drugs that you are taking and look them up yourself if you have experienced toxicity from these drugs. If you are not familiar with these drugs, please see our Introduction to Fluoroquinolones. The following is a list of the various chemical names. This list is evolving all of the time as new drugs are being developed.
The different classes denote different chemical substitutions at different points in the chemical structure for various therapeutic reasons. See DrugBank.ca or see the History of the Fluoroquinolones from structure to activity to toxicity powerpoint for more specific information on the chemical makeup of each of these various drugs, if you are interested in that type of in-depth information. These different chemical substitutions also cause unique problems in the human body, from a higher risk of collagen disruptions such as Tendon Rupture and Aortic Aneurysm, to DNA Damage, and much much more..
Be aware that, “The distinction between a quinolone drug and a fluoroquinolone drug is the addition of the fluorine atom to the pharmcore, resulting in a fluorinated drug. The terms fluoroquinolone and quinolone are often used interchangeably, without regard to this distinction” From Fluoroquinolone Toxicity. Even more importantly, it’s vital to understand that Half of All Antibiotic Use is Unnecessary, so be aware and read the rest of this site to understand the dangers involved when you take these drugs, and what you can do to avoid being prescribed these drugs unnecessarily.
