Pharmacokinetics and Pharmacodynamics of Suxamethonium

Pharmacokinetics and pharmacodynamics of atracurium with and without previous suxamethonium administration.

Suxamethonium increases neuromuscular block produced by non-depolarizing agents administered subsequently. To determine if this effect has a pharmacokinetic or pharmacodynamic origin, 18 ASA physical status I or II adults received atracurium 0.2 mg kg-1, with (n = 10) or without (n = 8) previous injection of suxamethonium 1 mg kg-1, during a thiopentone-nitrous oxide-isoflurane (0.5% end-tidal)...

Pharmacokinetics/ Pharmacodynamics

Topiramate: pharmacokinetics and pharmacodynamics.

Topiramate is a structurally novel anti-epileptic drug with at least 3 postulated mechanisms of action including: 1) potentiation of GABA responses, 2) impairment of AMPA/kainate glutamate receptors and 3) suppression of high frequency action potential firing. It has a favourable pharmacokinetic profile with rapid absorption, good bio-availability, linear pharmacokinetics, relatively long half-...

Macrolides: pharmacokinetics and pharmacodynamics.

Three pharmacokinetic/pharmacodynamic parameters--(i) the peak concentration to the minimum inhibitory concentration ratio (C(max)/MIC); (ii) the area under the concentration-time curve to MIC ratio (AUC(24h)/MIC); and (iii) the time the concentration exceeds the MIC (T>MIC)--are important predictors of the clinical efficacy of antibiotics. For antibiotics with pronounced concentration-dependen...

Antifungal pharmacokinetics and pharmacodynamics.

Successful treatment of infectious diseases requires choice of the most suitable antimicrobial agent, comprising consideration of drug pharmacokinetics (PK), including penetration into infection site, pathogen susceptibility, optimal route of drug administration, drug dose, frequency of administration, duration of therapy, and drug toxicity. Antimicrobial pharmacokinetic/pharmacodynamic (PK/PD)...
