The authors assessed the potential for a pharmacokinetic/pharmacodynamic interaction between desloratadine and fluoxetine. This randomized, placebo-controlled, open-label study was conducted in 54 healthy volunteers. Subjects received 1 of 3 treatments: desloratadine 5 mg plus fluoxetine 20 mg, desloratadine 5 mg plus placebo, or fluoxetine 20 mg plus(More)
Desloratadine, a nonsedating histamine H(1)-receptor antagonist, is metabolized to 3-hydroxy (3-OH) desloratadine. Impaired hepatic function could result in increased exposure to desloratadine. This study assessed possible differences in the pharmacokinetics and safety of desloratadine and 3-OH desloratadine in subjects (N = 21) with moderate hepatic(More)
Antihistamines are widely used to treat allergic rhinitis (AR) and chronic idiopathic urticaria (CIU) in adults and children. Desloratadine is a once-daily oral antihistamine with a favourable sedation profile that is approved for the treatment of AR and CIU. Phenotypic polymorphism in the metabolism of desloratadine has been observed, such that some(More)
Posaconazole is an orally bioavailable triazole antifungal agent for the treatment and prophylaxis of invasive fungal infection. We evaluated plasma posaconazole concentration data from juvenile (younger than 18 years; n = 12) and adult (18 to 64 years; n = 194) patients who participated in a multicenter, phase 3, open-label study that assessed the efficacy(More)
Posaconazole is a triazole antifungal for prophylaxis of invasive fungal infection and treatment of oropharyngeal candidiasis. We evaluated the effects of gender, age, and race/ethnicity (black or white) on the steady-state pharmacokinetics of posaconazole in two studies on healthy adult subjects (>or=18 years of age). Additionally, we explored the effect(More)
OBJECTIVE Posaconazole is an extended-spectrum triazole antifungal agent for the treatment and prophylaxis of invasive fungal infections. This randomized, open-label, parallel-group, multiple-dose study was conducted in healthy adult volunteers to assess the potential for a drug interaction between phenytoin and the posaconazole tablet formulation.

BACKGROUND Significant cardiac toxicity has been associated with some older antihistamines (eg, terfenadine and astemizole) when their plasma concentrations are increased. There is thus a need for a thorough assessment of the cardiac safety of newer antihistamine compounds. OBJECTIVE This study was undertaken to assess the effects of coadministration of(More)
STUDY OBJECTIVE To analyze the pharmacokinetic properties of the immunosuppressants cyclosporine and tacrolimus when either is coadministered with oral posaconazole. DESIGN Two single-center, open-label pharmacokinetic studies of cyclosporine in a multiple-dose design and of tacrolimus in a one-sequence, crossover, single- and multiple-dose design. (More)
We conducted a randomized, crossover study in healthy adults to examine the effects of a nutritional supplement (Boost Plus) on posaconazole pharmacokinetics. In this study, coadministration of posaconazole with Boost Plus increased the maximum concentration of posaconazole in serum and area under the concentration-time curve from 0 to 72 h values 3.4- and(More)
These studies were conducted to assess the systemic bioavailability of mometasone furoate (MF) administered by both the dry-powder inhaler (DPI) and the metered-dose inhaler with an alternate propellant (MDI-AP). The pharmacokinetics of single doses (400 micrograms) of MF administered by intravenous (i.v.) and inhalation routes was assessed in a randomized,(More)
