I-Fluoroquinolones ine-spectrum ebanzi ye-antibacterial, umsebenzi oqinile we-antibacterial, ukusabela okungalungile okuphansi, ukungena kahle kwezicubu, i-bioavailability ephezulu yomlomo, isikhathi eside sokuphatha kanye nokuphatha okulula.Zivame ukusetshenziswa ekwelapheni izifo ezithathelwanayo ezifana nokutheleleka kwepheshana lokuphefumula kanye nokutheleleka kwe-urinary tract.Isakhiwo semithi elwa namagciwane i-fluoroquinolone ibonakala ngokuba khona kwe-fluorine endaweni yesithupha ye-nucleus yomzali we-quinolone.
Kodwa-ke, eminyakeni eyi-10 yamuva nje, ngenxa yengcindezi ekhethiwe evezwa ukusetshenziswa okubanzi kwalolu hlobo lwezidakamizwa, izinhlobo ezimelana nezidakamizwa ziyanda, ikakhulukazi eminyakeni yamuva nje, i-quinolone-resistant Streptococcus pneumoniae ine-cross-resistance, ekwazi ukumelana ne-penicillin, ama-macrolide antibiotic kanye ne-quinolone antibiotics.Ngasikhathi sinye, kwatholakala ukuthi amanye ama-fluoroquinolones angabangela ukwelulwa kwesikhawu se-QTc kwe-electrocardiogram, i-hepatotoxicity kanye ne-phototoxicity, okukhawulela ukusetshenziswa kwazo.
Ukuze unqobe lokhu kushiyeka okungenhla kwe-fluoroquinolones, kuyaphuthuma ukuthuthukisa izinhlanganisela ezintsha zesakhiwo ezinomsebenzi omuhle we-antibacterial, i-spectrum ebanzi ye-antibacterial kanye nokusabela okubi okungahle kube okuncane ngangokunokwenzeka ngokumelene namagciwane aphikisana nezidakamizwa eziningi.Uchungechunge lwemithi emisha esanda kuthuthukiswa ye-fluoroquinolone-free (NFQ) equkethe i-8-methoxyl ihlukile kuma-antibiotic e-fluoroquinolone ngoba ayinayo i-fluorine endaweni yesi-6 ye-nucleus yomzali we-quinolone, kodwa isenomsebenzi oqinile we-in vitro antibacterial.I-nemonoxacin iyi-NFQ entsha ekhethiwe ye-bacterial topoisomerase inhibitor.
Uma kuqhathaniswa nama-fluoroquinolones asemakethe njengamanje, i-Nenofloxacin imele isigaba esisha semithi yesakhiwo.I-nemonocacin (TG-873870), umuthi omusha we-quinolone owakhiwe yi-Procter & Gamble (P&G), ubonise umsebenzi obalulekile wokulwa namagciwane ngokumelene nezinhlobonhlobo zamagciwane abalulekile emitholampilo, okuhlanganisa i-Staphylococcus aureus kanye ne-Streptococcus pneumoniae engazweli emithini eminingi.Imiphumela yokuhlolwa kwamagundane anegciwane ibonise ukuthi umphumela we-antibacterial walo mkhiqizo wawunamandla kuneningi lama-quinolones amanje.Ngaphezu kwalokho, umkhiqizo unezakhiwo ezinhle kakhulu ze-pharmacokinetic futhi ubekezelelwa kahle.
