Comparative pharmacokinetics and pharmacodynamics of cardiac glycosides.

Comparative pharmacodynamics and clinical pharmacokinetics of phenoxymethylpenicillin and pheneticillin.

In this study the antimicrobial effects of phenoxymethylpenicillin (PM) and pheneticillin (PE) in vitro and in an experimental animal infection model were compared as well as the pharmacokinetic properties of both drugs in patients. For the inhibitory effect of PM on short-term (3 h) growth of S. aureus in vitro, this drug was 2.13 times more potent than PE. The protein binding of both drugs wa...

Comparative pharmacodynamics and pharmacokinetics of candesartan and losartan in man.

The angiotensin II antagonistic effects of candesartan and losartan were compared in-vivo after single and repeated doses. Effects were related to antagonistic activity in plasma. In this double-blind, crossover study, 12 healthy male volunteers received, in random order, daily oral doses of 8 mg candesartan cilexetil or 50 mg losartan for seven days. On day 1 and day 8, dynamics and kinetics w...

Pharmacokinetics, bioavailability and serum levels of cardiac glycosides.

Digoxin, the cardiac glycoside most frequently used in clinical practice in the United States, can be given orally or intravenously and has an excretory half-life of 36 to 48 hours in patients with serum creatinine and blood urea nitrogen values in the normal range. Since the drug is excreted predominantly by the kidney, the half-life is prolonged progressively with diminishing renal function, ...

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-...
