Effects of ciprofloxacin and ofloxacin on adult human cartilage in vitro

Abstract: Chondrocyte toxicity and necrosis were seen with electron microscopy after incubation of human adult cartilage biopsy specimens in ciprofloxacin or ofloxacin. In vitro exposure of chondrocytes to fluoroquinolones did not affect apoptosis as determined by flow cytometry. While the immediate clinical significance of this finding remains unclear, the possibility of long-term cartilage damage after fluoroquinolone treatment cannot be excluded.

“…1,2 It acts mainly by inhibiting a type II topoisomerase, DNA gyrase, which is necessary for the unwinding of replicated prokaryotic DNA. 2 It has been shown, however, that this mechanism can also affect mammalian cell replication through the inhibition of eukaryotic topoisomerases.…”

“…These chronic and intermittent loads to the joint cartilage induce production of nitrogen oxide (NO) and nitrogen oxide synthase which damage the joint cartilage (Fermor et al, 2001). The frequent intake of antibiotics, especially the gyrase inhibitor, may further reduce the strength of the temporomandibular joint and surrounding structure (Menschik et al, 1997).…”
