Pharmacokinetics history

Review the pharmacokinetic history. Are there any possible changes in clearance since the last antibiotic course Will the patient be discharged home on IV antibiotics Can the IV regimen be simplified or made more convenient for home administration Recommend appropriate doses based on the patient s clearance and an appropriate but convenient schedule.

Although most CF patients have shorter half-lives and larger volumes of distribution than non-CF patients, some patients exhibit decreased clearance. Possible causes include concomitant use of nephrotoxic medications, presence of diabetic nephropathy, history of transplantation (with immunosuppressant use and/or procedural hypoxic injury), and age-related decline in renal function in older adult patients. Additionally, CF patients are repeatedly exposed to multiple courses of IV aminoglycosides, which can result in decreased renal function. Evaluation of previous pharmacokinetic parameters and trends, along with incorporation of new health information, is key to providing appropriate dosage recommendations. 

The speciflc clinical use of the numerous available benzodiazepines depends on their individual pharmacokinetic and pharmacodynamic properties. Drugs with a high affinity for the GABAa receptor (alprazolam, clonazepam, lorazepam) have high anxiolytic efficacy drugs with a short duration of action (temazepam) are used as hypnotics to minimise daytime sedative effects. Diazepam has a long half-life and duration of action and may be favoured for long-term use or when there is a history of withdrawal problems oxazepam has a slow onset of action and may be less susceptible to abuse. 

F]-fluoride has a long history as a tracer for bone imaging. In 1962, this tracer was first introduced by Blau et al. [188]. [ F]-fluoride-PET imaging combines the superior pharmacokinetic properties of F-fluoride (compared with those of [99mTc]-polyphosphonates) and the improved spatial resolution and lesion... 

The increasing use of stimulants in the United States to treat attention deficit hyperactivity disorder (ADHD) has aroused parental concern and compelled both medical professionals and the media to question the safety and efficacy of this type of treatment. Because ADHD is among the most common reasons for seeking mental health services for children, these questions are more pertinent than ever. This chapter will examine the history of stimulant use, the mechanism of action, pharmacokinetics, side effects, and issues related to their clinical use in children and adolescents. More detailed information on clinical applications is provided in Section III. 

Finally, a good personal drug history often reveals that iatrogenic polypharmacy contributes to ill health, both physical and psychiatric, in elderly patients. Pharmacokinetic and Pharmacodynamic Issues... 

The commonsense approach to the interpretation of drug concentrations compares predictions of pharmacokinetic parameters and expected concentrations to measured values. If measured concentrations differ by more than 20% from predicted values, revised estimates of Vd or CL for that patient should be calculated using equation (1) or equation (2). If the change calculated is more than a 100% increase or 50% decrease in either Vd or CL, the assumptions made about the timing of the sample and the dosing history should be critically examined. 

The patient s recorded time history of dosing can be used as input to pharmacokinetic (PK) models, to project the time history of drug concentra-...
