<p>The use of a drug administration plan and therapeutic drug monitoring (TDM) based on pharmacokinetic-pharmacodynamic (PK-PD) analysis is important for the effective use of antimicrobial agents to treat infections. We focused on the use of beta-lactam agents, anti-methicillin-resistant Staphylococcus aureus (MRSA) agents, and an antifungal agent as antimicrobial agents and examined their efficacy in patients under special clinical conditions from the viewpoint of safety and TDM. Our PK-PD analysis of the use of an administration plan to set an optimum serum level for beta-lactam agents or anti-MRSA drugs for the treatment of pneumonia, acute renal failure during continuous hemodialysis filtration, febrile neutropenia, or malignant tumors confirmed the necessity of managing the optimal serum level. PK-PD analysis was also useful for TDM of voriconazole and intubation administration in long-term use from the viewpoint of preventing the onset of side effects. PK-PD analysis appears to be a useful tool in antibiotic therapy and TDM for developing a pharmacokinetic “individual difference” for “individualization therapy” under special clinical conditions. PK-PD analysis utilizes the restrictive information that is obtained by a clinic to the maximum and allows coordination with the mission of hospital pharmacists to provide adequate antibiotic therapy.</p>
