about ciprofloxacin -it is a broad spectrum fluoroquinolone with activity against pseudomonas aeruginosa. -eye drops: it is a fluroquinolone antibacterial having broad spectrum of activity. -mechanism of action of ciprofloxacin -ciprofloxacin is a bacteriostatic at low concentration and bactericidal at high concentration. it act by inhibiting the enzyme dna gyrase (topoisomerase 2) and topoisomerase 4.dna gyrase helps in the formation of a highly condensed three dimensional structure of the dna by its nicking and closing activity and also by introducing negative supercoil in to the dna double helix. ciprofloxacin inhibits dna gyrase which results in abnormal linkage between opened dna and gyrase and negative supercoiling is also impaired. this will inhibits transcription of dna in to rna and subsequent protein synthesis.
