Fluoroquinolones | 2nd vs 3rd vs 4th Generation | Targets, Mechanism of Action

The video tutorial covers fluoroquinolones, a class of antibiotics ending in 'floxacin'. It discusses their absorption, distribution, and bacterial targets, including gram-positive and gram-negative bacteria. The tutorial explains the differences in activity across generations, with later generations having broader spectrums. The mechanism of action involves inhibiting bacterial DNA synthesis by targeting DNA gyrase and topoisomerase IV. It also addresses antibiotic resistance mechanisms and adverse reactions, such as gastrointestinal symptoms, QT prolongation, and tendinopathy, emphasizing caution in children and pregnant women.
