Once-daily maraviroc versus tenofovir/emtricitabine each combined with darunavir/ritonavir for initial HIV-1 treatment.

Objective: The aim of this study was to evaluate the efficacy of maraviroc along with darunavir/ritonavir, all once daily, for the treatment of antiretroviral-naive HIV-1 infected individuals.

Design: MODERN was a multicentre, double-blind, noninferiority, phase III study in HIV-1 infected, antiretroviral-naive adults with plasma HIV-1 RNA at least 1000 copies/ml and no evidence of reduced susceptibility to study drugs.

Methods: At screening, participants were randomized 1 : 1 to undergo either genotypic or phenotypic tropism testing.

Comparison of azithromycin pharmacokinetics following single oral doses of extended-release and immediate-release formulations in children with acute otitis media.

An azithromycin extended-release (ER) oral suspension was developed to improve the gastrointestinal tolerability profile without substantially compromising systemic exposure. A single dose of 30 mg/kg azithromycin immediate-release (IR) oral suspension has been used in children to treat acute otitis media (AOM). This study was conducted to compare the pharmacokinetics of a 60-mg/kg azithromycin ER single dose with a 30-mg/kg azithromycin IR single dose in children with AOM aged 6 months to 6 years (n = 19 per treatment).

Bronchopulmonary disposition of intravenous voriconazole and anidulafungin given in combination to healthy adults.

Voriconazole and anidulafungin in combination are being investigated for use for the treatment of pulmonary aspergillosis. We determined the pulmonary disposition of these agents. Twenty healthy participants received intravenous voriconazole (at 6 mg/kg of body weight every 12 h [q12h] on day 1 and then at 4 mg/kg q12h) and anidulafungin (200 mg on day 1 and then 100 mg every 24 h) for 3 days.

Pharmacokinetics of azithromycin in plasma and sinus mucosal tissue following administration of extended-release or immediate-release formulations in adult patients with chronic rhinosinusitis.

This study compared the pharmacokinetics of azithromycin (AZI) following administration of extended-release (ER) and immediate-release (IR) formulations in plasma and sinus mucosa in patients with chronic rhinosinusitis. Patients (n=71) were randomised 1:1 to receive a single dose of AZI-ER 2g or up to three doses of AZI-IR 500 mg daily. Paired plasma and sinus tissue samples were taken during endoscopic sinus surgery at 2-168 h (four patients per time point) after the first dose.

Significant decrease in nelfinavir systemic exposure after omeprazole coadministration in healthy subjects.

Study Objectives: To assess the effect of omeprazole on the multiple-dose (steady-state) pharmacokinetics and safety of nelfinavir, and to evaluate the safety and tolerability of nelfinavir when administered alone and with omeprazole.

Design: Open-label, two-period, single-fixed-sequence study.

Setting: Clinical research unit of a large, teaching hospital.

Metabolism and disposition of a selective alpha(7) nicotinic acetylcholine receptor agonist in humans.

The metabolism and disposition of N-(3R)-1-azabicyclo[2.2.2]oct-3-ylfuro[2,3-c]pyridine-5-carboxamide (1), an alpha(7) nicotinic acetylcholinergic receptor agonist, were elucidated in humans (4 female, 4 male; all white) after an oral dose of [(3)H]1.
