A comparative pharmacokinetic and pharmacodynamic investigation was carried out on the interaction between the hypnotic midazolam and 2 different macrolide-type antibiotics, clarithromycin and azithromycin. In an open randomized crossover study of 3 phases 12 healthy volunteers received either clarithromycin (250 mg twice a day for 5 days), azithromycin(More)
AIM To carry out a prospective study of cardiac arrest survivors to understand the qualitative features as well as incidence, and possible aetiology of near death experiences (NDEs) in this group of patients. METHOD All survivors of cardiac arrests during a 1 year period were interviewed within a week of their arrest, regarding memories of their(More)
Sperm design and function are important determinants of male reproductive success and are expected to be under strong selection. The way that spermatozoa phenotypes evolve is poorly understood, because there have been few studies of the quantitative genetics of sperm. Here we show, in the zebra finch Taeniopygia guttata, an extraordinary degree of(More)
The pharmacokinetic and pharmacodynamic interaction between azithromycin (CAS 83905-01-5), an azalide antibiotic, and midazolam (CAS 59467-70-8), a short-acting hypnotic agent, was investigated in an open, three-way cross-over study, including erythromycin (CAS 114-07-8) as a positive control. Twelve healthy male and female subjects had standard doses of(More)
Fluconazole shows good penetration into the tissues and body fluids examined and a rapid equilibrium is achieved between the concentrations in the various compartments. The pharmacokinetics of fluconazole after intravenous or oral administration are proportional to the dose. This finding, together with the slow elimination of the triazole (t1/2 30 h), makes(More)
Antibody responses were measured in a volunteer infected four times with Necator americanus over a 27-month period. The main source of antigen was culture fluid in which living adult N. americanus had been maintained for several days. Antibodies to worm acetylcholinesterase and IgE antibodies were detected only with this material, but antibodies were(More)
Fluconazole (Diflucan, CAS 86386-73-4) suppositories offer a novel way to administer this systemically active antimycotic. The pharmacokinetics and toleration of this new formulation have now been examined in healthy adult volunteers. In crossover experiments the bioequivalence was demonstrated for 200 mg suppositories and 200 mg capsules, and for 25 mg(More)
