And lactic acid) in sodium chloride intravenous infusion solution. The assay of an IV formulation is performed using a liquid chromatographic method, which requires the following solutions. For solution (1), dilute a quantity of the intravenous infusion with sufficient mobile phase to produce a solution containing the equivalent of 0.05% w/v of impurity C EPCRS (ethylenediamine compound) in solution (2). For solution (4), dilute 1 volume of solution (3) to 100 volumes with the mobile phase. The chromatographic procedure may be carried out using a stainless steel column (12.5 cm×4 mm) packed with stationary phase C (5 mm) (Nucleosil C18 is suitable). The mobile phase is eluted at a flow rate of 1.5 m L/min, and consists of a mixture of 13 volumes of acetonitrile and 87 volumes of a 0.245% w/v solution of orthophosphoric acid (the p H of which has been adjusted to 3.0 with triethylamine). Analytes are detected on the basis of their UV absorption at 278 nm. If you're reading this article, you may have been prescribed ciprofloxacin (Cipro), levofloxacin (Levaquin) or some other type of fluoroquinolone for the treatment of a bacterial infection (think respiratory or urinary tract infection). Overall, these drugs are safe and effective against a wide array of gram-positive and gram-negative bacterial pathogens making them a good choice for systemic or body-wide treatment. At the core of all fluoroquinolones—including drugs like ciprofloxacin and levofloxacin—are 2 six-member carbon rings attached to a fluoride atom. These drugs work by targeting 2 bacterial enzymes responsible for notching, coiling, and sealing DNA during replication: DNA gyrase and topoisomerase IV. Because current fluoroquinolones bind to 2 separate enzymes, it's harder for bacteria to mutate and to evade the actions of these drugs. In addition to broad-spectrum bacterial coverage, fluoroquinolones also sport other properties that make them great antibiotics. First, they are taken by mouth (and not by injection).
