This evolution has allowed clinicians to address a wider range of complex infections with a single class of medication. Historical Development and Evolution The journey of quinolone antibiotics began with the discovery of nalidixic acid in the 1960s, which served as the prototype for this class of drugs.
Quinolone Antibiotic First Generation Examples and Their Historical Development
By inhibiting these enzymes, quinolones cause DNA to become fragmented and prevent the bacteria from repairing the damage, effectively halting bacterial growth and leading to cell death. Resistance mechanisms often involve mutations in the target enzymes or the expression of efflux pumps that expel the drug from the bacterial cell.
There are also warnings regarding potential effects on cartilage development, which is why they are generally avoided in children and pregnant women unless no alternative exists. Their development marked a significant advancement in the fight against bacterial infections, offering treatment options for conditions where older antibiotics were ineffective.
