Evaluation of in vitro Penetration of Fluticasone Propionate from MP-AzeFlu and Fluticasone Propionate Nasal Spray Through EpiAirway™606 Tissues Using Vertical Diffusion Cells.

Purpose: Most patients with allergic rhinitis (AR) have moderate-to-severe disease, requiring complete and prompt relief when symptoms occur. The time course of fluticasone propionate (FP) penetration into nasal tissues after intranasal administration is not well characterized. The goal of this proof-of-concept study was to evaluate the mucosal penetration of FP from fixed-combination FP-azelastine nasal spray (MP-AzeFlu) compared with an FP-only nasal spray in an in vitro, 3-dimensional human bronchial tissue model.

Deposition characteristics of a novel intranasal formulation of azelastine hydrochloride plus fluticasone propionate in an anatomic model of the human nasal cavity.

Intranasal antihistamines and steroids should be delivered in a volume and with a technique that allow for optimal drug retention within the entire nasal cavity, maximize local absorption by the nasal mucosa, and, subsequently, increase the potential for the most desirable local availability and therapeutic effect. This in vitro evaluation simulated nasal medication deposition and evaluated the extent of runoff. MP-AzeFlu, a novel intranasal formulation of azelastine hydrochloride (AZE) plus fluticasone propionate (FP), was compared with sequential sprays of available commercial products with the individual medication components.

A retrospective database analysis on persistence with inhaled corticosteroid therapy: comparison of two dry powder inhalers during asthma treatment in Germany.

Background: Asthma is one of the most common chronic diseases worldwide. Patient persistence with treatment is essential to achieve sufficient outcomes, in particular to avoid exacerbations.

Objective: To investigate inhaled corticosteroid (ICS) therapy with two different inhalers (Novolizer® and Turbuhaler®) by comparing persistence, concomitant use of additional asthma medication and occurrence of exacerbations in real life.

Bioavailability and disposition of azelastine and fluticasone propionate when delivered by MP29-02, a novel aqueous nasal spray.

What Is Already Known About This Subject: • The topical second generation anti-histamine azelastine hydrochloride (AZE) and the potent corticosteroid fluticasone propionate (FP) are well established first-line treatments in allergic rhinitis (AR). • MP29-02, a novel intranasal AZE and FP formulation, has been shown to control AR symptoms faster and better than standard intranasal AZE or FP. • The systemic bioavailabilities of marketed AZE and FP nasal spray products have been established at about 40% and 1% only, respectively.

Prevention of exercise-induced asthma by a fixed combination of disodium cromoglycate plus reproterol compared with montelukast in young patients.

Background: The leukotriene inhibitor montelukast has been recommended against exercise-induced asthma (EIA), however, single-dose agents might be favourable in several aspects.

Objective: To compare the protective effects against EIA of a single inhalation of the combination disodium cromoglycate (DSCG, CAS 16110-51-3) and reproterol (REP, CAS 54063-54-6) with 3 days oral treatment of montelukast (MON, CAS 158966-92-8).

Methods: Open-label, cross-over, single-centre trial.

Single-dose pharmacokinetics and safety pharmacodynamics of formoterol delivered by two different dry powder inhalers.

The present study aimed at assessing the pharmacokinetics (PK) and safety pharmacodynamics (PD) of 24 microg formoterol delivered via a Novolizer and via an Aerolizer in healthy subjects. This was a randomized, open-label, crossover study. Beside PK, serum potassium, and glucose profiles, vital signs, and ECG were recorded.

Tramadol SR Formulations : Pharmacokinetic Comparison of a Multiple-Units Dose (Capsule) versus a Single-Unit Dose (Tablet).

Introduction: Different oral sustained-release (SR) formulations of tramadol have been introduced in pain treatment in order to prolong the dosage interval to improve convenience for the patient. The objective of this study was to compare tramadol pharmacokinetics and intra- and intersubject variability after replicate single-dose administrations of a multiple-units SR formulation (capsule) and a single-unit formulation (tablet).

Methods: This was a randomised, single-dose, single-centre study with an open-label, four-period, two-sequence, two-formulation, replicate crossover design in healthy subjects under fed conditions.

Peak inspiratory flow rates generated through the Novolizer and the Turbuhaler dry powder inhaler devices by children with stable asthma.

We compared the peak inspiratory flows (PIF) generated through a novel dry powder inhaler device, the Novolizer (PIF-N), and the Turbuhaler (PIF-T). Forty-six pediatric patients with stable bronchial asthma were randomized in an open-label, multicenter, crossover trial. No drug was administered during the inhalation maneuvers that were spaced by 10 min.

Effect of azelastine, montelukast, and their combination on allergen-induced bronchoconstriction in asthma.

Objectives: Histamine and cysteinyl leukotrienes play an important role in early (EAR) and late (LAR) allergen reactions. Although protection by anti-histamines and anti-leukotrienes has been studied extensively, little is known about the effect of their combination. We, therefore, assessed the effect of clinically recommended doses of azelastine and montelukast alone and in combination on EAR and LAR.

Oral treatment with alpha-lipoic acid improves symptomatic diabetic polyneuropathy: the SYDNEY 2 trial.

Objective: The aim of this trial was to evaluate the effects of alpha-lipoic acid (ALA) on positive sensory symptoms and neuropathic deficits in diabetic patients with distal symmetric polyneuropathy (DSP).

Research Design And Methods: In this multicenter, randomized, double-blind, placebo-controlled trial, 181 diabetic patients in Russia and Israel received once-daily oral doses of 600 mg (n = 45) (ALA600), 1,200 mg (n = 47) (ALA1200), and 1,800 mg (ALA1800) of ALA (n = 46) or placebo (n = 43) for 5 weeks after a 1-week placebo run-in period. The primary outcome measure was the change from baseline of the Total Symptom Score (TSS), including stabbing pain, burning pain, paresthesia, and asleep numbness of the feet.

Synergistic effects of the anti-cholinergic R,R-glycopyrrolate with anti-inflammatory drugs.

Currently, much effort is geared towards developing therapies that impact on the inflammation in respiratory diseases such as asthma and COPD, assuming that this will improve disease pathology. R,R-Glycopyrrolate, a quaternary ammonium compound, is a muscarinic receptor antagonist with the potential to be used as a long-acting bronchodilator in patients with asthma and COPD. In this study we evaluated whether the combination of R,R-glycopyrrolate with known anti-inflammatory drugs results in synergistic effects.

Glycopyrrolate causes prolonged bronchoprotection and bronchodilatation in patients with asthma.

Introduction: Inhaled anticholinergic drugs are effective bronchodilators in the treatment of COPD, and tiotropium bromide has recently been introduced as a once-daily bronchodilator for use as a maintenance treatment. Racemic glycopyrrolate is an anticholinergic drug that has been used orally to control gastric acidity, parenterally as an antisialogogue and to reverse neuromuscular blockade, and has been studied by inhalation for asthma and COPD.

Design And Objective: We investigated the duration of protection against the constrictor effects of inhaled methacholine of a single dose of inhaled nebulized racemic glycopyrrolate (0.
