The following data were taken into account\: maximum serum drug concentration\/MIC90 ratio \(Cmax\/MIC90\) or twenty\-four\-hour area under the concentration\-time curve\/MIC90 \(AUC0\-24\/MIC90\) for antibacterial agents exerting concentrationdependent killing \(ciprofloxacin CPX, aminoglycoside antibiotics\) and the time during which serum drug concentration exceeds MIC90 \(tc>MIC\) for antibiotics exhibiting time\-dependent killing \(cefuroxim CFU\). To achive this goal, the analytical methods to detennine CPX, CFU and aminoglycosides were validated. Pharmacokinetics of these drugs in pathophysiological conditions was assessed. PK\/PD parameters were estimated in the patient populations studied and the efficacy of dosage regimen based on PK\/PD criteria was predicted in relatin to main pathogenes responsible for lower respiratory tract infections such as Haemophilus influenzae, Moraxella catarrhalis, Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa. Consequently, the drug dosage usually used was modified. The results of this study indicated that there was large variability in"]
