Economic impact of industry-sponsored clinical trials of pharmaceutical products in Austria.

Modern pharmaceutical product development is a long and complex process associated with significant investments by pharmaceutical companies. The innovative pharmaceutical industry accounts for the vast majority of expenditures in clinical trials of potential new pharmaceuticals and therefore generates economic activity within a country. The aim was to assess the far-reaching economic impact of industry-sponsored clinical-trials (ISCTs) of pharmaceutical products for the healthcare system and the national economy.

Prevalence of hypovitaminosis D and folate deficiency in healthy young female Austrian students in a health care profession.

Purpose: We performed a single-day cross-sectional study to assess the prevalence of vitamin D deficiency as well as folate status in healthy young female volunteers well educated with respect to health information.

Methods: We assessed dietary intake of vitamin D and calcium, serum concentrations of 25-OH-vitamin D(3), folate, red blood cell folate and other dietary, laboratory, and lifestyle parameters in 215 young healthy women (age 18-30 years) on a single day at the end of the winter months. Primary aim was to investigate the prevalence of hypovitaminosis D.

Pharmacokinetics of intravenous linezolid in cerebrospinal fluid and plasma in neurointensive care patients with staphylococcal ventriculitis associated with external ventricular drains.

The pharmacokinetic profile of linezolid in cerebrospinal fluid (CSF) in five neurointensive care patients with staphylococcal ventriculitis was studied. The mean area under concentration-time curve (+/- standard deviation) was 63 +/- 18.9 mg x h/liter, with a CSF-to-plasma ratio of 0.

A bioequivalence study of two oral desmopressin tablet formulations.

The present study was carried out to test bioequivalence between two different oral desmopressin formulations. Sixty healthy volunteers were enrolled in the study and were randomly assigned to receive the test (T) and reference (R) drug in a two-period two-sequence, crossover, analyst-blinded study design. Subjects received an oral dose of 400 mug of desmopressin acetate separated by a wash-out period of at least 7 days.

Sinoaortic denervation abolishes blood pressure-induced GABA release in the locus coeruleus of conscious rats.

Male Sprague-Dawley rats underwent sinoaortic denervation (SAD) or sham operation. We examined changes in the release rates of GABA, glutamate and arginine in the locus coeruleus (LC) elicited by experimental blood pressure increases (i.v.

A replicate study design for testing bioequivalence: a case study on two desmopressin nasal spray preparations.

Objective: The present study was carried out to test bioequivalence between two different desmopressin nasal spray preparations. Due to the high variability of plasma pharmacokinetics of intranasally administered peptides like desmopressin, appropriate study designs are required to assess bioequivalence. Therefore, a single-dose, replicate study design was used to evaluate bioequivalence of two desmopressin nasal sprays.
