The pharmacokinetics of lamotrigine have been studied in single and multiple dose studies in animals, normal volunteers, and patients with epilepsy. Lamotrigine exhibits first-order linear pharmacokinetics. Lamotrigine is well absorbed with bioavailability approaching 100%. The absorption is unaffected by food and there is no first-pass metabolism. The

Psychopharmacology and pharmacokinetics
2019The overall physiologic changes associated with aging lead to changes in both pharmacokinetic and pharmacodynamic actions of many medications. This, in turn, leads to changes in the impact that a wide variety of medications have on older adults when compared to younger, healthy individuals. These pharmacokinetic and pharmacodynamic variations can cause

PHARMACOKINETIC CONSIDERATIONS
Critical Care Clinics, 1999Limited studies of the pharmacokinetics of pain medication suggest altered serum elimination when the liver is hypoperfused or affected by severe cirrhosis. Drugs that are eliminated by Phase I oxidation reactions are sensitive to changes in hepatic blood flow, while drugs eliminated by Phase II glucuronidation are more affected by diseased hepatocytes.

Pharmacokinetics in the elderly
European Journal of Clinical Pharmacology, 1975The pharmacokinetics of sulphamethizole, paracetamol and phenylbutazone were investigated and compared in young and geriatric subjects. The rate and extent of absorption of the drugs did not appear to be affected by increasing subject age. However, the mean half-lives for sulphamethizole and paracetamol were significantly increased in the geriatric ...

This paper reviews the clinically relevant determinants of levodopa peripheral pharmacokinetics and main observed changes in the levodopa concentration-effect relationship with Parkinson's disease (PD) progression. Available clinically practical strategies to optimise levodopa pharmacokinetics and pharmacodynamics are briefly discussed.

Developmental Pharmacokinetics
2011The advances in developmental pharmacokinetics during the past decade reside with an enhanced understanding of the influence of growth and development on drug absorption, distribution, metabolism, and excretion (ADME). However, significant information gaps remain with respect to our ability to characterize the impact of ontogeny on the activity of ...

Pharmacokinetics of toremifene
Journal of Steroid Biochemistry, 1990The pharmacokinetics of toremifene has been investigated in man after single and multiple oral doses. Toremifene was completely absorbed without first-pass metabolism. Peak concentration in serum was achieved in 4 h. Mean half-lives of distribution and elimination were 4 h and 5 days, respectively.

Despite the clinical use of deferoxamine for more than a quarter of a century, pharmacokinetic studies are few and have not been performed explicitly in patients with sickle cell disorders. Early studies with Intravenous administration to healthy volunteers and patients with transfusional overload showed that although peak concentrations of ...

Pharmacokinetics is the study of the fate of xenobiotics in a living organism. Physiologically based pharmacokinetic (PBPK) models provide realistic descriptions of xenobiotics' absorption, distribution, metabolism, and excretion processes. They model the body as a set of homogeneous compartments representing organs, and their parameters refer to ...

An introduction to pharmacokinetics
Journal of Chronic Diseases, 1983Abstract Concepts of pharmacokinetics including kinetic models, first order processes, apparent volume of distribution, half-life, clearance, duration of drug action, dose schedules and plasma drug concentration monitoring are briefly outlined.
