Pharmacodynamics of antimicrobial drugs.

نویسنده

چکیده

Knowledge of the antimicrobial pharmacodynamic characteristics of a drug (inhibition of growth, rate and extent of bactericidal action, and postantibiotic effect) provides a more rational basis for determination of optimal dosing regimens in terms of the dose and the dosing interval. This article reviews concepts of antimicrobial pharmacodynamics, the effect of pharmacodynamics on the emergence of resistant bacterial subpopulations, and the development of pharmacodynamic breakpoints for use in the design of trials of these drugs and in treatment of infected patients.

Pk-pd Integration and Pk-pd Modelling: Alternatives to Dose Titration Studies for Selecting Optimal Dosage Schedules of Antimicrobial Drugs

4. There are universally applicable formulae for systemically acting (including antimicrobial) drugs which: (a) define the relationship between the 3 pivotal pharmacokinetic (PK) parameters, clearance, volume of distribution and elimination half-life; (b) define drug action (pharmacodynamics, PD) quantitatively through the sigmoidal Emax equation, linking concentration to effect; (c) predict a ...

Pharmacokinetics and pharmacodynamics in the development of antifungal compounds.

Antimicrobial pharmacodynamics describe the relationship between drug exposure and treatment outcome. Pharmacodynamic studies provide information useful for dose level and dosing interval selection and for the development of in vitro susceptibility guidelines. Pharmacodynamic observations from animal model studies have proven useful for outcome predictions in the treatment of human infections. ...

Pharmacodynamics of Quinolone Antimicrobial Agents

Pharmacodynamics describes the relationship between measures of drug levels in serum and tissue fluids and the antimicrobial and toxicologic effects of drugs (5, 10, 17, 49). While there have been numerous studies describing the pharmacokinetics of fluoroquinolones in serum and tissues, there has been much less emphasis on describing the time course of antimicrobial activity with these drugs. T...

Pharmacokinetics and pharmacodynamics of drug interactions involving rifampicin, rifabutin and antimalarial drugs.

Malaria and tuberculosis (TB) are two major global diseases mostly affecting the developing countries. Their treatment is often complex because of the drugs used, multidrug resistance, drug interactions and logistic problems such as drug availability and access. Patients are treated for TB for a minimum of 6 months and may concomitantly develop and be treated for malaria, especially during the ...

Standardization of pharmacokinetic/pharmacodynamic (PK/PD) terminology for anti-infective drugs.

Over the last decades, the interest in the relationships between the pharmacokinetics (PK) and pharmacodynamics (PD) of antimicrobial agents has increased and, therefore, the use of PK/PD indices and expressions has spread widely. The appropriate definition and use of these parameters is a matter of controversy. This paper contains a proposal to use PK/PD expressions for antimicrobial agents an...
