Antibiotic therapy relies on understanding both pharmacokinetics (PK) and pharmacodynamics (PD), which respectively address drug absorption, distribution, and elimination, and the relationship between drug concentration and antimicrobial efficacy. This review synthesizes decades of research, drawing from studies, models, and clinical observations, to elucidate the temporal dynamics of antibiotic activity. We explore how these dynamics, including concentration-effect relationships and post antibiotic effects, inform the classification of antibiotics based on their PD profiles. Additionally, we discuss the pivotal role of PK/PD principles in determining optimal dosage regimens. By providing a comprehensive overview of PK/PD principles in antibiotic therapy, this review aims to enhance understanding and improve treatment outcomes in clinical practice.

The development of antibiotic resistance and inadequate immune response in chronic inflammation pose significant challenges in treating chronic osteomyelitis. As accepted non-antibiotic antimicrobial therapies, sonodynamic therapy (SDT) and photothermal therapy (PTT) are recognized for their effectiveness in eliminating bacteria and promoting tissue repair, rendering them promising therapeutic strategies for treating bacterial infections and preventing the emergence of drug-resistant bacteria. However, the antimicrobial action and efficacy in promoting tissue repair depend on the activation status of the host immune system.

Organ transplant recipients require continual immune-suppressive therapies to sustain allograft acceptance. Although medication nonadherence is a major cause of rejection, the mechanisms responsible for graft loss in this clinically relevant context among individuals with preceding graft acceptance remain uncertain. Here, we demonstrate that skin allograft acceptance in mice maintained with clinically relevant immune-suppressive therapies, tacrolimus and mycophenolate, sensitizes hypofunctional PD1hi graft-specific CD8+ T cells.
