A new macro-Raman system equipped with a motorized translational sample stage and low-frequency shift capabilities was developed for bulk composition and homogeneity analysis of multi-component pharmaceutical powders. Different sampling methods including single spot and scanning measurement were compared. It was found that increasing sample volumes significantly improved the precision of quantitative composition analysis, especially for poorly mixed powders. The multi-pass cavity of the macro-Raman system increased effective sample volumes by 20 times from the sample volume defined by the collection optics, i...

Eczema is a chronic inflammatory skin disorder with considerable impact on quality of life. Emollients or moisturisers are widely recommended, but are these effective and safe? We searched for randomised controlled trials (RCTs) in the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library, Medline, Embase, LILACS, GREAT database and five trial registers to December 2015. We included 77 RCTs with 6603 participants. Seven studies (9.1%) were at low risk of bias, 34 (44.2%) at unclear and 36 (46...

AIM: Studies have linked the use of inhaled corticosteroids (ICS) to excess pneumonia risk in COPD patients. The risk in asthma patients remains unclear. The objective was to examine the risk of pneumonia with ICS in patients 12 to 35 years old with asthma. METHODS: We formed a cohort of asthma patients treated from 1990-2007 using Quebec health insurance databases. Subjects were considered currently exposed if they had an ICS dispensed within the 60 days prior to their pneumonia index event or matched person-moment...

Ahmed O Shalash, Mustafa M A Elsayed
The potential of fine excipient materials to improve the performance of carrier-based dry powder inhalation mixtures is well acknowledged. The mechanisms underlying this potential are, however, open to question till date. Elaborate understanding of these mechanisms is a requisite for rational rather than empirical development of ternary dry powder inhalation mixtures. While effects of fine excipient materials on drug adhesion to and detachment from surfaces of carrier particle have been extensively investigated, effects on other processes, such as carrier-drug mixing, capsule/blister/device filling, or aerosolization in inhaler devices, have received little attention...

OBJECTIVES: Cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD) often coexist. We assessed the effect of inhaled COPD treatments on CVD outcomes and safety in patients with COPD and at heightened CVD risk. METHODS: The SUMMIT (Study to Understand Mortality and MorbidITy) was a multicentre, randomised, double-blind, placebo-controlled, event-driven trial in 16 485 patients with moderate COPD who had or were at high risk of CVD. Here, we assessed the prespecified secondary endpoint of time to first on-treatment composite CVD event (CVD death, myocardial infarction, stroke, unstable angina or transient ischaemic attack (TIA)) by Cox regression and by clinician-reported CVD adverse events across the four groups: once-daily inhaled placebo (n=4111), long-acting beta2-agonist (vilanterol (VI) 25 µg; n=4118), corticosteroid (fluticasone furoate (FF) 100 µg; n=4135) and combination therapy (FF/VI; n=4121)...

Focal dermal hypoplasia (FDH) is a rare disorder of the mesodermal and ectodermal tissues. Here we present an eight-year-old female known to have FDH who presents with poor weight gain and dysphagia. She was diagnosed with multiple esophageal papillomas and eosinophilic esophagitis. She was successfully treated with argon plasma coagulation and ingested fluticasone propionate, which has not been described previously in a child.

BACKGROUND: Prednisone dependence in asthma is usually described based on clinical and spirometric characteristics. It is generally believed that these patients have frequent exacerbations and lose lung function rapidly because of uncontrolled airway eosinophilia. OBJECTIVES: The objectives of this study are to report the effect on asthma exacerbations and the change in lung function over time in prednisone-dependent asthma when severe asthma is managed using a protocol that aims to maintain normal sputum cell counts...

REVIEW
J-L Corhay
The place of combinations of bronchodilators (longacting beta-agonist / muscarinic agonist or LABA / LAMA) in the prevention of the exacerbations of the chronic obstructive pulmonary disease (COPD) is not still clearly established, and need a comparison with combination of LABA/ inhaled steroids. FLAME was a randomized non-inferiority phase 3 study comparing indacaterol/glycopyrronium 110/50 μg (IND/GLY) once daily with salmeterol/proprionate of fluticasone 50/500 μg (SAL/FC) twice daily. The primary objective of the study was to demonstrate that IND/GLY was non-inferior to SAL/FC in terms of reduction of all COPD exacerbations (mild/moderate/severe) during 52 weeks of treatment in patients having had at least 1 exacerbation in previous 12 months...

BACKGROUND: Guidelines recommend reducing treatment in patients with well-controlled asthma after 3 months of stability. However, there is inadequate real-life data to guide physicians on therapy change in daily practice. OBJECTIVE: To assess asthma control after change to and step-down of fluticasone propionate/formoterol fumarate dihydrate (FP/FOR) in real-life patients. METHODS: In a randomized controlled, pragmatic, open-label trial, 225 well-controlled patients with asthma were randomized (1:2) to maintain high-dose fluticasone propionate/salmeterol xinafoate (FP/SAL, 1000/100 μg) or switch to FP/FOR (1000/40 μg) daily for 12 weeks (phase 1)...

The main purpose of this work was to develop an in vitro method for simulating the dissolution and absorption of inhaled dry powder drugs that also mimics systemic pharmacokinetic data. A second purpose was to evaluate this method. DissolvIt(®) was developed as a simulation of the air-blood barrier of the upper airways, constituting: "airborne" particles deposited on a glass cover slip, a mucus simulant, a polycarbonate (basal) membrane, and a pumped albumin buffer simulating the pulmonary blood flow. The PreciseInhale(®) exposure system was used to aerosolize and deposit test formulations onto cover slips...
