Context: Conflicting results on the effects of salicylates on glucose tolerance in subjects with normal glucose tolerance or type 2 diabetes have been reported.Objective: The objective of the study was to investigate the effects of a salicylate derivative (triflusal) on insulin sensitivity and insulin secretion.Design, Setting, and Participants: This was a double-blind, randomized, crossover study with three treatment periods corresponding to two dose levels of triflusal and placebo in healthy obese subjects.Main Outcome Measures: Insulin sensitivity and insulin secretion, evaluated through frequently sampled iv glucose tolerance test that was performed after each treatment period, were measured. Insulin secretion was also evaluated in vitro in mice and human islets of Langerhans.Results: The administration of triflusal led to decreased fasting serum glucose concentration in the study subjects. Insulin sensitivity did not significantly change after each treatment period. Insulin secretion, however, significantly increased in a dose-dependent fashion after each triflusal treatment period. The administration of 800 μm of the main triflusal metabolite to whole mice islets of Langerhans led to a sustained increase in intracellular calcium concentration level. This was followed by a significantly increase in insulin secretion. In human islets, 200 μm of 2-hydroxy-4-trifluoromethylbenzoic acid was sufficient to increase insulin release.Conclusions: The administration of a salicylate compound led to lowering of serum glucose concentration. We suggest that this effect was mediated through increased insulin secretion induced by salicylate directly on the β-cell.

This randomised, double-blind, parallel group phase II/III study with adaptive two-stage design and interim analysis compared the efficacy and tolerability of spray (containing a Salvia officinalis fluid extract) against placebo in the treatment of patients with acute viral pharyngitis. -

in two study parts, a total of 286 patients with subjective and objective evidence of pharyngitis were randomized. In the first study part 122 patients were enrolled. In the second study part 164 patients were included. The treatment duration per patient was 3 days, including one baseline visit and one final visit. -

Area under Curve for change of throat pain intensity (spontaneous pain), documented every 15 minutes within the first 2 hours after the first application as compared to baseline using a visual analog scale (VAS 100 mm). -

Following the interim analyses of the first study part the 15 % spray containing 140 microl sage extract per dose was the most promising preparation for the second study part (main study) whereas for the 30% and the 5% preparation results made superiority over placebo unlikely in the final analysis. Overall, the 15 % spray was significantly superior to placebo for the primary efficacy variable with regard to a reduction of the throat pain intensity score. Only minor side effects such as dry pharynx or burning of mild intensity were seen. -

The efficacy and tolerability profile of a 15 % sage spray indicated that this preparation provides a convenient and safe treatment for patients with acute pharyngitis. A symptomatic relief occurred within the first two hours after first administration and was statistically significantly superior to placebo.

A new series of 2,2-dialkylnaphthalen-1-one potassium channel activators has been prepared, and their in vitro relaxant activities in isolated rat portal vein and guinea pig tracheal spirals as well as their oral antihypertensive effect in spontaneously hypertensive rats have been evaluated. The group of 1,2-dihydro-4-(1,2-dihydro-2-oxo-1-pyridyl)-2,2-dimethylnaphthalen -1- ones with an electron-withdrawing substituent at the 6-position contain the most active compounds and 1,2-dihydro-4-(1,2-dihydro-2-oxo-1-pyridyl)-2,2-dimethyl-1-oxonaphtha lene-6- carbonitrile, 17f (UR-8225), has been selected for further pharmacological development.
