The main types of pharmacologic therapy used to treat the hormone deficiency of menopause are parenteral and oral administrations of estrogen. Parenteral administration results in predictable absorption without major intermediary metabolism, whereas all oral estrogens are subject to intestinal metabolism before entering the systemic circulation ...

Fractional calculus in pharmacokinetics
Journal of Pharmacokinetics and Pharmacodynamics, 2018We are witnessing the birth of a new variety of pharmacokinetics where non-integer-order differential equations are employed to study the time course of drugs in the body: this is dubbed “fractional pharmacokinetics”.

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.

Pharmacokinetics (PK) describes how the concentration of a dosed drug and its metabolites in body fluids and tissues changes with time. PK models the concentration-time profile using key parameters, such as volume of distribution (Vd), area under the curve (AUC), clearance (CL), half-life (t1/2), maximum concentration (Cmax), and bioavailability (F ...

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 ...

The pharmacokinetics of glyburide can be described by a two-compartment open model. Terminal-phase descriptions are formulation-dependent and are complicated by apparent food-associated mobilization of drug from the stomach. Some researchers indicate a possible third (or deep) compartment, but this appears to be an artifact of a nonspecific drug assay.

Pharmacokinetics of Ceftriaxone
Hospital Practice, 1991Ceftriaxone fulfills many of the qualities of an ideal antibiotic: a prolonged elimination half-life, which results from a "restrictive" excretion pattern; saturable protein binding, which provides the theoretical basis for administering the total daily dose as a single bolus; and once-a-day dosing, which provides plasma and tissue concentrations that ...

The Pharmacokinetization of Psychiatry
The Journal of Clinical Pharmacology, 1985The titration and monitoring of drug therapy using pharmacokinetic principles along with measurements of serum or plasma drug concentrations have become essential components of pharmacotherapy in many areas of clinical medicine, including the treatment of asthma, seizure disorders, certain infectious diseases, and cardiac arrhythmias.
