Clinical pharmacokinetic data on antiretroviral drugs are scarce in African HIV-1-positive patients. Most available pharmacokinetic data are derived from ethnically distinct Caucasian research volunteers. This presentation will focus on the clinical pharmacokinetics training and research outputs of an HIV Research Trust scholarship recipient in Uganda. The work highlights the need for post-mark...

The objective was to evaluate possible pharmacokinetic and pharmacodynamic interactions for repeated nightly zolpidem dosing with fluoxetine. Twenty-nine healthy female volunteers (mean age, 25. 6 years) received zolpidem (10 mg) and fluoxetine (20 mg) in the following open design: zolpidem on night 1 followed by 1 washout day, a daily morning dose of fluoxetine on days 3 through 27, and a morn...

Journal of the Malta College of Pharmacy Practice 23 In this paper an overview will be given of how knowledge of pharmacokinetic mechanisms determines which pharmacokinetic characteristics an AED should have. Various clinical factors such as age, underlying physiological conditions and drug interactions will also affect the pharmacokinetics and efficacy of AED medication. It will be shown how b...

BACKGROUND In open TCI and anaesthesia display systems, the choice of pharmacokinetic (PK) parameter sets of opioids is clinically relevant. Accuracy and bias of the PK models may be affected by administration mode and the co-administered hypnotic drug. We retrospectively evaluated the performance of eight PK parameter sets for alfentanil in two data sets (infusion and bolus application). MET...

Occupational exposure limits (OELs) for active pharmaceutical ingredients have traditionally been established using no-observed-adverse-effect levels derived from clinical studies employing po and iv routes of administration and by applying default uncertainty factors or chemical-specific adjustment factors. However, exposure by the inhalation or dermal route is more relevant in terms of occupa...

BACKGROUND A recent drug interaction study reported that when azithromycin was administered with the combination of ivermectin and albendazole, there were modest increases in ivermectin pharmacokinetic parameters. Data from this study were reanalyzed to further explore this observation. A compartmental model was developed and 1,000 interaction studies were simulated to explore extreme high iver...

OBJECTIVES Nevirapine is widely used in the developing world for the prevention of mother-to-child transmission (PMTCT) of HIV. A single mutation in the HIV genome is sufficient to lead to significant nevirapine resistance. Persistence of low-level drug concentrations in body compartments can foster resistance formation. In this study, concentration-time courses of nevirapine after single-dose ...

BACKGROUND Correct antibiotic dosing remains a challenge for the clinician. The aim of this study was to assess the influence of augmented renal clearance on pharmacokinetic/pharmacodynamic target attainment in critically ill patients receiving meropenem or piperacillin/tazobactam, administered as an extended infusion. METHODS This was a prospective, observational, pharmacokinetic study execu...

Monitoring cyclosporine therapy is required by the narrow therapeutic index, high pharmacokinetic variability, the increased risk of drug interactions CYP 3A4dependent and nephrotoxicity of the substance substance. The controversies raised by clinical practice are the best time of sampling, the analytical methods used and the feasibility of the pharmacokinetic models to estimate the useful conc...

there is no randomized study carried out in order to compare their pharmacokinetic parameters although midazolam, as a sedative, has been widely administered via continuous infusion as well as intermittent bolus doses in mechanically ventilated critically ill patients. we prospectively investigated the effect of these two principal methods on pharmacokinetic parameters in 23 of mentioned patien...
