Liraglutide is a novel once-daily human glucagon-like peptide (GLP)-1 analog in clinical use for the treatment of type 2 diabetes. To study metabolism and excretion of [(3)H]liraglutide, a single subcutaneous dose of 0.75 mg/14.2 MBq was given to healthy males. The recovered radioactivity in blood, urine, and feces was measured, and metabolites were(More)
A multiple-dose, open-label, two-period, crossover randomized study was conducted in 12 healthy male volunteers to investigate the effect of multiple-dose telmisartan on the steady-state pharmacokinetics of digoxin. On day 1 of a 7-day medication period, subjects received a loading dose of digoxin 0.5 mg in the morning, followed by an evening dose of(More)
The possible role of prostaglandins in the mediation and/or modulation of the urethral response to vesical distension was investigated in female dogs. Three criteria for the possible involvement of these mediators have been investigated. Indomethacin could block the reduction of urethral resistance observed during vesical distension. Intra-arterial infusion(More)
Escherichia coli, as most Gram-negative bacteria, is insensitive to the photosensitizing action of both lipid-soluble Zinc-phthalocyanine (Zn-Pc) and water-soluble Zinc-mono/disulfonated phthalocyanine (Zn-PcS). Photosensitivity can be induced by alteration of the outer membrane, as obtained by either induction of competence or treatment with Tris-EDTA.(More)
The effects of multiple-dose telmisartan on the steady-state pharmacodynamics and pharmacokinetics of warfarin were assessed in 12 healthy young males in an open-label, single-period study conducted over 30 days. Subjects received loading doses of oral once-daily warfarin on days 1 to 5, which were individually adjusted at days 6 and/or 9 to attain stable(More)
The mass balance and metabolite profiles of 2-(2-amino-1,3-thiazol-4-yl)-N-[4-(2-{[(2R)-2-hydroxy-2-phenylethyl]amino}ethyl)[U-(14)C]phenyl]acetamide ([(14)C]mirabegron, YM178), a β(3)-adrenoceptor agonist for the treatment of overactive bladder, were characterized in four young, healthy, fasted male subjects after a single oral dose of [(14)C]mirabegron(More)
AIMS Zolmitriptan (Zomig (formerly 311C90)) is a novel 5-HT1B/1D receptor agonist developed for the acute oral treatment of migraine. A highly sensitive LCMS-MS assay has been developed which allows quantification of plasma concentrations of zolmitriptan and its active metabolite, 183C91, after therapeutic doses. Two studies using this assay method were(More)
We evaluated the effects of a Ginkgo biloba/ginseng combination on cognitive function in this 90-day, double-blind, placebo-controlled, parallel-group study. Sixty-four healthy volunteers (aged 40 to 65 years), selected on the basis of fulfilling the ICD-10 F48.0 criteria for neurasthenia, were assigned randomly to four equal dosing groups, receiving 80,(More)
Cilengitide (EMD 121974, manufactured by Merck KGaA, Darmstadt, Germany) is an αv-integrin receptor antagonist showing high affinity for αvβ3 and αvβ5.This study determined the mass balance of cilengitide in healthy volunteers receiving a single intravenous infusion of 2.1 MBq (14) C-cilengitide spiked into 250 mL of 2000 mg of cilengitide. Blood, urine,(More)
