Reliable anticoagulation with enoxaparin in patients undergoing percutaneous coronary intervention: The pharmacokinetics of enoxaparin in PCI (PEPCI) study.

The objective of this study was to evaluate the pharmacokinetic response to intravenous (IV) enoxaparin given 8-12 hr after subcutaneous (SC) dosing in patients undergoing percutaneous coronary intervention (PCI). Fifty-five patients received SC enoxaparin (1 mg/kg every 12 hr) followed by an IV bolus (0.3 mg/kg) 8-12 hr after the last SC dose, at the start of PCI or during catheterization.

Pharmacokinetics and pharmacodynamics of the prophylactic dose of enoxaparin once daily over 4 days in patients with renal impairment.

The pharmacokinetics of the low-molecular-weight heparin enoxaparin were evaluated in 12 healthy volunteers and 36 patients with mild, moderate or severe renal impairment. Enoxaparin was administered once daily by subcutaneous injections at a dose of 40 mg for 4 days and venous blood samples were taken over a 5-day period to determine antifactor Xa and antifactor IIa activity and the activated partial thromboplastin time. Adverse events were also recorded.

[Statistical analysis in the evaluation of controlled diffusion of iodine in the water in developing countries].

This report describes the methodology and findings of a novel statistical technique for evaluation of the efficacy of the Rhodifuse Iode system in prevention of endemic goiter in Mali. The system involves continuous release of iodine in ground water used for drinking. Study was carried out in four villages for one year.

A comparison of the pharmacokinetics and tolerability of riluzole after repeat dose administration in healthy elderly and young volunteers.

The pharmacokinetics and tolerability of the novel antiexcitatory agent, riluzole, were compared in 18 healthy elderly and 18 healthy gender- and weight-matched young volunteers. All participants received riluzole 50 mg twice daily (the recommended dosage for patients with amyotrophic lateral sclerosis), administered orally for 5 days. The pharmacokinetics of riluzole, determined on the morning of the 5th day of dosing, were not significantly affected by age or gender.

Use of the repeated cross-over design in assessing bioequivalence: (within and between subjects variability - Schuirmann Confidence Intervals estimation).

In 1992, the Division of Bioequivalence in the Office of Generic Drugs published a guide to Statistical procedures for bioequivalence studies using a standard two-treatments cross-over design (1). This paper describes the application of the guidelines to a practical protocol and the recent Proc MIXED (SAS) will be shown to be much more convenient than the traditional Proc GLM for theoretical and practical reasons (correct estimation of residuals, analysis of the within-subjects variation, direct calculation of the Schuirmann 90% Confidence Intervals). This new procedure was applied to a study protocol on riluzole (Rilutek) including a replicate design with the within-subject and between-subject variances being estimated on Cmax and AUC biopharmaceutic parameters.
