Pharmacodynamics of fluoroquinolones.

The newer fluoroquinolones.

Clinicians have enthusiastically used fluoroquinolones owing to their good safety profile and wide range of indications. This article reviews fluoroquinolone pharmacology, pharmacodynamic principles, and fluoroquinolone resistance mechanisms, highlighting recent trends in the epidemiology of fluoroquinolone resistance among gram-negative organisms and Streptococcus pneumonia. Important fluoroqu...

Pharmacodynamics of fluoroquinolones in experimental models of endocarditis.

We calculated the magnitude of various serum pharmacodynamic parameters for fluoroquinolones in models of experimental endocarditis (EE) described in the literature. Nineteen publications contained data that allowed calculation of these parameters. Data were available for eight fluoroquinolones against methicillin-susceptible Staphylococcus aureus, methicillin-resistant S. aureus, methicillin-r...

Clinical perspectives on new antimicrobials: focus on fluoroquinolones.

Respiratory tract infections are the most common infectious presentation in the community and hospital settings and are a major cause of morbidity and mortality worldwide. Recently, newer fluoroquinolones have been recommended for the treatment of these infections. Among them, moxifloxacin shows improved activity against gram-positive pathogens, has maintained potency against gram-negative orga...

Moxifloxacin, ofloxacin, sparfloxacin, and ciprofloxacin against Mycobacterium tuberculosis: Evaluation of in vitro and pharmacodynamic indices that best predict in vivo efficacy Running Head: Activity of fluoroquinolones vs. M. tuberculosis Authors

Pharmacokinetics and pharmacodynamics of newer fluoroquinolones.

Newer fluoroquinolones currently under development have excellent pharmacokinetic profiles, and several parameters have been improved compared with those of their predecessors. These compounds are well absorbed, have large volumes of distribution, and distribute into most tissues at concentrations equal to or greater than those observed in serum. Moreover, these newer agents have long serum eli...

Skin and skin structure infections: treatment with newer generation fluoroquinolones

Skin and skin structure infections (SSSI) are an emerging issue in healthcare. They are responsible for increasing heathcare utilization, both in hospitalizations and intravenous antibiotic use. SSSI are caused by an evolving variety of pathogens, including Gram-positive, Gram-negative, and anaerobic bacteria. In combination with mounting resistance patterns, this diverse range of bacteria mand...
