This clinical trial is focused on studying two diseases: Chronic Obstructive Pulmonary Disease (COPD) and Cystic Fibrosis (CF). The study will explore the effects of two medications, Levofloxacin and Piperacillin/Tazobactam, which are both given as a solution for infusion, meaning they are administered directly into the bloodstream through a vein. The purpose of the study is to compare different methods of measuring how these antibiotics behave in the lungs of patients with COPD or CF.
Participants in the study will receive either Levofloxacin or Piperacillin/Tazobactam as part of their treatment. The study will involve taking samples from the lungs to measure the concentration of the antibiotics. This will be done using three methods: collecting fluid from the lining of the lungs, taking a small tissue sample, and using a technique called in-vivo microdialysis, which involves measuring the drug concentration in the body over a period of time. These methods will help researchers understand how the drugs are distributed in the lungs.
The study will be conducted over a short period, with the main focus on comparing the three methods of measurement. The results will provide valuable information on how these antibiotics work in the lungs of patients with Chronic Obstructive Pulmonary Disease and Cystic Fibrosis, potentially leading to better treatment strategies in the future.
