Randomized Controlled Trial Clinical TrialA randomized, placebo-controlled study of a new sublingual formulation of fentanyl citrate (fentanyl ethypharm) for breakthrough pain in opioid-treated patients with cancer.
Oromucosal fentanyl is currently used for the treatment of breakthrough pain (BTP) in opioid-treated cancer patients. Ethypharm developed a sublingual formulation of fentanyl suprabioavailable to oral transmucosal fentanyl citrate with a higher early systemic exposure and a shorter Tmax. ⋯ This newly developed galenic formulation with a higher early systemic exposure and a shorter Tmax compared with oral transmucosal fentanyl citrate makes FE a particularly suitable formulation for the management of BTP in opioid-treated cancer patients due to the very rapid onset of action. FE provided significant improvement in pain intensity of BTP compared with placebo as early as 6 minutes' postadministration with a sustained effect over 60 minutes. FE was well tolerated by patients. ClinicalTrials.gov identifier: NCT 01842893.

Meta AnalysisSystemic antifungal prophylaxis after hematopoietic stem cell transplantation: a meta-analysis.
Hematopoietic stem transplant recipients are subject to increased risk for invasive fungal infections. ⋯ Even when on antifungal therapy, invasive fungal infection will develop in 1 of 20 patients undergoing hematopoietic stem cell transplantation. There is evidence for the comparable effectiveness of different antifungal drugs used for prophylaxis. Fluconazole is the most widely studied agent, but micafungin might prove to be more effective. There is a relative paucity of studies for the newer azoles, although both voriconazole and posaconazole give proof of their comparative or higher effectiveness to fluconazole in single randomized studies.

Randomized Controlled TrialPharmacokinetics of a novel orodispersible tablet of sildenafil in healthy subjects.
Sildenafil citrate is indicated for the treatment of erectile dysfunction. An orally disintegrating tablet (ODT) of sildenafil citrate has been developed for the benefit of patients who have difficulty swallowing solid dosage forms. ⋯ Sildenafil ODT, given with or without water, provides equivalent systemic exposure compared with marketed sildenafil film-coated oral tablets, thus offering a convenient alternative method of administration. Considering the results of the food-effect study, sildenafil ODT should be taken on an empty stomach. ClinicalTrials.gov identifiers: NCT01254383 (bioequivalence) and NCT01254396 (food effect).

Randomized Controlled TrialTolerability and pharmacokinetic properties of ondansetron administered subcutaneously with recombinant human hyaluronidase in minipigs and healthy volunteers.
Subcutaneous ondansetron facilitated by recombinant human hyaluronidase PH20 (rHuPH20) is an alternative for treating nausea/vomiting in patients who cannot receive ondansetron by other routes of administration. ⋯ Subcutaneous ondansetron + rHuPH20 was generally well-tolerated. Subcutaneous dosing resulted in an extent of systemic exposure similar to that with intramuscular or intravenous dosing and greater than that with oral administration, and may be an option for clinical administration of ondansetron. ClinicalTrials.gov identifier: NCT01572012.

Comparative StudyCost-effectiveness of apixaban versus other new oral anticoagulants for stroke prevention in atrial fibrillation.
Apixaban (5 mg BID), dabigatran (available as 150 mg and 110 mg BID in Europe), and rivaroxaban (20 mg once daily) are 3 novel oral anticoagulants (NOACs) currently approved for stroke prevention in patients with atrial fibrillation (AF). ⋯ Although our analysis was limited by the absence of head-to-head trials, based on the indirect comparison data available, our model projects that apixaban may be a cost-effective alternative to dabigatran 150 mg BID, dabigatran 110 mg BID, and rivaroxaban 20 mg once daily for stroke prevention in AF patients from the perspective of the United Kingdom National Health Services.
