Eosinophilic esophagitis is a common atopic disease of the esophagus. APT-1011 is an orally disintegrating tablet formulation of fluticasone propionate under development for the treatment of eosinophilic esophagitis. The objective of this study was to evaluate the pharmacokinetics, safety, and tolerability of APT-1011 under fed or fasted conditions in the morning (am) or at bedtime (hs) in the supine position.

Objective: To examine if North Carolina (NC) opioid prescribing guidelines were associated with changes in opioid prescribing.

Method: Retrospective secondary analysis of the Medicare Provider Utilization and Payment Data: Part D Prescriber datasets from 2013 to 2015.

Participants: Providers who prescribed at least one opioid from 2013 to 2015 and paid by Medicare Part D.

With healthcare costs on the rise, a global initiative was launched in 2007, called Exercise is Medicine, to prescribe and counsel patients on exercise to aid in the prevention and treatment of chronic diseases. Since community pharmacists are one of the most accessible healthcare providers, this is an opportunity for pharmacists to also engage in this initiative. This study aimed to assess pharmacy student perceptions and knowledge on exercise to determine whether they are adequately prepared to counsel patients on exercise prescription.

Objectives: To assess the effect of intra-operative radiology on the quality of lag screw insertion for the management of sacroiliac joint luxations in cats.

Methods: In this retrospective single-centre study, the surgical, anaesthetic and imaging records of 40 screws (32 cats) placed with lag effect for management of sacroiliac luxation were reviewed. Postoperative radiographs were assessed for sacroiliac joint reduction, screw position, and sacral width purchased by each screw.

Unlabelled: GPR119 receptor agonists improve glucose metabolism and alter gut hormone profiles in animal models and healthy subjects. We therefore investigated the pharmacology of GSK1292263 (GSK263), a selective GPR119 agonist, in two randomized, placebo-controlled studies that enrolled subjects with type 2 diabetes. Study 1 had drug-naive subjects or subjects who had stopped their diabetic medications, and Study 2 had subjects taking metformin.

Objective: To evaluate, using inverse dynamic analysis, the biomechanical outcome from tibial tuberosity advancement (TTA) surgery in dogs affected by unilateral cranial cruciate ligament failure (CCLF).

Study Design: Retrospective case series.

Animals: Dogs (n = 13) 11-20 months after surgery.

Article Synopsis
  • * Administering clinically relevant doses (2, 5, and 10 mg) for 10 days showed that the drug was well tolerated with no significant health risks, and it did not noticeably alter vital signs or blood tests.
  • * While GSK1521498 demonstrated some cognitive and pain tolerance effects—especially at higher doses—results were positive overall, suggesting it has a good safety profile and supports further clinical testing.

Article Synopsis
  • Testosterone can be taken orally as a treatment for hypogonadism, and a new formulation has shown promise in normalizing testosterone levels.
  • In a study, twelve healthy young men were induced with low testosterone levels and given the oral formulation three times daily for nine days.
  • Results indicated that while total testosterone levels decreased slightly over time, free testosterone remained stable, and the treatment significantly reduced sex hormone-binding globulin (SHBG), suggesting potential effectiveness for testosterone deficiency.

Endogenous opioids and µ-opioid receptors have been linked to hedonic and rewarding aspects of palatable food intake. The authors examined the safety, pharmacokinetic, and pharmacodynamic profile of GSK1521498, a µ-opioid receptor inverse agonist that is being investigated primarily for the treatment of overeating behavior in obesity. In healthy participants, GSK1521498 oral solution and capsule formulations were well tolerated up to a dose of 100 mg.

Purpose: Co-administration of the 5α-reductase inhibitor dutasteride increases the oral testosterone bioavailability in men with experimentally induced hypogonadism. We examined oral testosterone with and without dutasteride administration in hypogonadal men for 28 days.

Materials And Methods: We randomly assigned 43 hypogonadal men to twice daily oral doses of 150, 250 or 400 mg testosterone with 0.

Oral administration of testosterone might be useful for the treatment of testosterone deficiency. However, current "immediate-release" formulations of oral testosterone exhibit suboptimal pharmacokinetics, with supraphysiologic peaks of testosterone and its metabolite, dihydrotestosterone (DHT), immediately after dosing. To dampen these peaks, we have developed 2 novel modified-release formulations of oral testosterone designed to slow absorption from the gut and improve hormone delivery.

Objective: To investigate safety, pharmacokinetics and pharmacodynamics of albiglutide in Japanese subjects with type 2 diabetes mellitus.

Research Design And Methods: This randomized, single-blind, placebo-controlled study examined four doses/dose schedules of subcutaneously (sc) administered albiglutide: 15 mg weekly, 30 mg weekly, 50 mg biweekly, and 100 mg monthly (cohorts A-D, respectively) in 40 subjects (mean age 54.5 years, mean range of glycosylated hemoglobin [HbA(1c)] 7.

Context: Native glucagon-like peptide-1 increases insulin secretion, decreases glucagon secretion, and reduces appetite but is rapidly inactivated by dipeptidyl peptidase-4. Albiglutide is a novel dipeptidyl peptidase-4-resistant glucagon-like peptide-1 dimer fused to human albumin designed to have sustained efficacy in vivo.

Objectives: The objectives were to investigate pharmacodynamics, pharmacokinetics, safety, and tolerability of albiglutide in type 2 diabetes subjects.

Oral androgen development has been hampered by the rapid metabolism of orally administered testosterone (T) and low bioavailibility. The addition of the 5alpha-reductase inhibitor dutasteride (D) to oral T in oil dramatically improves concentrations of serum T. In this study we evaluate the absorption of oral T+D, comparing nanomilled T (NmT+D) vs T dissolved in oil (Capmul; CpT+D), as nanomilling might offer a simpler, more practical means of oral T administration, given the limited solubility of T in oil.
