A Comparison of Cardiovascular Biomarkers in Patients Treated for Three Months with Etoricoxib, Celecoxib, Ibuprofen, and Placebo.

OBJECTIVES: Selective cyclooxygenase (COX)-2 inhibitors are effective analgesic and anti-inflammatory agents with improved gastrointestinal safety and tolerability compared with traditional NSAIDs. However, data from long-term, placebo-controlled studies have shown an increased risk of thrombotic cardiovascular (CV) events for COX-2 inhibitors. Changes in levels of CV biomarkers are potentially useful surrogate measures of pathologic changes associated with CV risk.

Pharmacokinetics and safety of montelukast oral granules in children 1 to 3 months of age with bronchiolitis.

The single-dose pharmacokinetics of montelukast 4-mg oral granules and tolerability of daily administration of 2 different doses of montelukast (4 mg and 8 mg given once daily for 7 days) versus placebo were evaluated in 12 infants 1 to 3 months of age with bronchiolitis or a history of bronchiolitis and asthma-like symptoms. The population area under the concentration-time curve estimate after a single 4-mg dose of montelukast was 13 195.7 +/- 2309.

Efficacy and safety of sitagliptin monotherapy in Japanese patients with type 2 diabetes.

Efficacy and tolerability of sitagliptin, a dipeptidyl peptidase-4 inhibitor, were assessed in Japanese patients with type 2 diabetes. In a multicenter, double-blind, randomized, placebo-controlled trial in Japan, 151 patients with inadequate glycemic control [HbA(1c) > or =6.5% to <10%, fasting plasma glucose (FPG) > or =126 to < or =240 mg/dL] were randomized to once-daily sitagliptin 100mg or placebo for 12 weeks.

Effect of aprepitant on the pharmacokinetics of intravenous midazolam.

Oral aprepitant 125 mg, an antiemetic and a moderate inhibitor of the metabolism of oral midazolam, was assessed for interaction with intravenous midazolam in 12 subjects randomized to intravenous midazolam 2 mg +/- oral aprepitant 125 mg. The hypothesis was that midazolam AUC would not change by more than 2-fold (consistent with no more than weak inhibition) when midazolam + aprepitant was compared with midazolam alone. An AUC geometric mean ratio (midazolam + aprepitant/midazolam) with 90% confidence interval upper bound < or =2.

Lack of effect of aprepitant on hydrodolasetron pharmacokinetics in CYP2D6 extensive and poor metabolizers.

To prevent chemotherapy-induced nausea and vomiting, aprepitant is given with a corticosteroid and a 5-hydroxytryptamine type 3 antagonist, such as dolasetron. Dolasetron is converted to the active metabolite hydrodolasetron, which is cleared largely via CYP2D6. The authors determined whether aprepitant, a moderate CYP3A4 inhibitor, alters hydrodolasetron pharmacokinetics in CYP2D6 poor and extensive metabolizers.

A double-blind, dose-response study of losartan in hypertensive children.

Background: The aim of this study was to determine the dose-response relationship for losartan, 2.5 to 100 mg, and to assess the safety and tolerability of losartan in hypertensive children 6 to 16 years of age.

Methods: This was a multicenter, randomized, double-blind, dose-response study.

Lack of effect of aprepitant on the pharmacokinetics of docetaxel in cancer patients.

Background: Aprepitant is a selective neurokinin-1 receptor antagonist that is effective for the prevention of nausea and vomiting caused by highly emetogenic chemotherapy. In vitro, aprepitant is a moderate inhibitor of the CYP3A4 enzyme, which is involved in the clearance of several chemotherapeutic agents. In this study we examined the potential for aprepitant to affect the pharmacokinetics and toxicity of intravenously administered docetaxel, a chemotherapeutic agent that is primarily metabolized by CYP3A4.
