CUE BRUGUERAS, Manuel; MOREJON GARCIA, Moisés  y  SALUP DIAZ, Rosa. Present situation of quinolonesPresent situation of quinolones. Rev Cubana Farm [online]. 2005, vol.39, n.1, pp.1-1. ISSN 0034-7515.

The quinolones are antimicrobial agents that have attained their highest development in the last years. After obtaining nalidixic acid, in 1962, several compounds were developed with similar characteristics that were only established as urinary antiseptics and that were the first generation of quinolones until 1978, when the addition of a piperazinyl group in position 7 and an atom of fluor in position 6 made possible the development of a series of antibacterial agents called piperazinyl fluoroquinolones, or simply fluoroquinolones . The first of them was norfloxacin, with which a greater antimicrobial activity of the group and its systemic use was achieved. For years, the fluoroquinolones were considered as an homogeneous group of antibiotics with similar characteristics and, therefore, as the second and last possibility of generation of quinilones, but the chances of transformation of their chemical structure have produced a vertiginous development of this group, which makes it the most accelerated within the antibiotics, with compounds of higher antibacterial spectrum, tissue penetration and safety and with a lower manifestation of antimicrobial resistance that has been proved up to now. At present, there are 4 generations of quinolones, their use is wider and their development continues. As a result of it, it is made a review that includes spectrum and mechanism of action, bacterial resistance, pharmacodynamics and pharmacokinetics, drug interactions, adverse effects, indications and dosage of the most used
