The efficiency of lung drug delivery of nebulized drugs is governed by aerosol quality, which depends both on the aerosolization process itself but also on the properties of aerosol precursors. This paper determines physicochemical properties of four analogous micro-suspensions of a micronized steroid (budesonide, BUD) and seeks relationships between these properties and the quality of the aerosol emitted from a vibrating mesh nebulizer (VMN). Despite the same BUD content in all tested pharmaceutical products, their physicochemical characteristics (liquid surface tension, viscosity, electric conductivity, BUD crystal size, suspension stability, etc.

Introduction: Salbutamol is used in bronchodilator response testing (BDRT), which is an important diagnostic tool in bronchial obstructive diseases. Most available studies compare the bronchodilator response of salbutamol administered with a pressurized metered-dose inhaler and salbutamol in a nebulization solution.
Aim: The spirometric evaluation of the bronchodilator response of two methods of salbutamol nebulization in asthmatic children.
In order to improve targeted therapeutic approaches for asthma patients, insights into the molecular mechanisms that differentially contribute to disease phenotypes, such as obese asthmatics or severe asthmatics, are required. Here we report immunological and microbiome alterations in obese asthmatics (n = 50, mean age = 45), non-obese asthmatics (n = 53, mean age = 40), obese non-asthmatics (n = 51, mean age = 44) and their healthy counterparts (n = 48, mean age = 39). Obesity is associated with elevated proinflammatory signatures, which are enhanced in the presence of asthma.

Rarely, interstitial pneumonitis (IP) occurs as a serious complication in CAEBV patients. The standard therapeutic regimen for IP in CAEBV has not yet been defined.

Basing on the data from the literature, we discussed the most common mistakes related to the utilisation of DPI as well as their clinical and economic consequences. We also extensively analysed all factors that may influence the efficacy and safety of inhaler therapy of asthma and COPD, mostly with the use of DPI.

The aim of this nonrandomized, open-label, postauthorization efficacy study (PAES) real-life clinical assessment was to evaluate the clinical effectiveness of a second product (Bufomix Easyhaler) in the daily clinical practice of asthma therapy.
Methods: This multicenter PAES was conducted by 220 unselected allergologists and pulmonologists who enrolled 2200 adult outpatients (age 49.
Background: Postoperative pain can be prevented. Gabapentin may be effective in this role. Our primary objective was to test the hypothesis that a prophylactic administration of gabapentin in obese patients before surgery has an opioid-sparing effect and reduces postoperative oxycodone consumption more efficiently than placebo.

Inhalation therapy is a convenient method of treating respiratory diseases. The key factors required for inhalation are the preparation of drug carriers (aerosol particles) allowing reproducible dosing during administration. These technical challenges are accomplished with a variety of inhalation devices (inhalers) and medicinal formulations, which are optimized to be easily converted into inhalable aerosols.

In this review, the implementation of the pharmacovigilance legislative framework by EU regulators is examined with the aim of mapping Directive 2010/84/EU and Regulation EC No. 1235/2010 against their aspired objectives of strengthening and rationalizing pharmacovigilance in the EU.

The regulation of generic products is well-established, and is primarily based on standard rules for quality, therapeutic equivalence requirements (the latter in most instances proven through a bioequivalence study), and safety data for the innovator. The extensive experience from bringing generic products to the market over the last decades allows the conclusion that they are well-accepted and provide a useful alternative option for cost-effective pharmacotherapy.

Both are flow independent in the physiological range of flows seen in patients with asthma and/or COPD. Both require three actions (open-load -inhaler) for a successful inhalation.

The small airways are those < 2 mm in diameter and are significant sites of chronic asthmatic inflammation. It is important, therefore, to target the small as well as the large airways in any strategy for effective treatment of this disease.

Orally inhaled products delivered via inhalation exert their effect directly to the target organ. This allows to administer a very low dose of a drug compared with an oral route with similar clinical effect and significantly reduced toxicity. However inhalation therapy is also limited by several factors.

Methods: We analysed all the adopted Day 120 list of questions on the quality module of 52 marketing authorisation applications for chemical entity medicinal products submitted to the European Medicines Agency and evaluated by the Committee for Medicinal Products for Human Use (CHMP), during 12 consecutive plenary meetings held in 2007 and 2008. Subsequently we calculated the frequency of common deficiencies identified across these applications.

CEA, NSE and SCC Ag levels were measured in bronchial lavage (BL) and serum in patients with endobronchial lung cancer (LC) and in patients with nonmalignant lung diseases (NMLD). In both groups of patients 100 ml of normal saline solution was used during the lavage procedure. Tumor markers were detected using radioimmunoassay.

It was found out that NSE levels in bronchial lavage fluid were much lower than in serum and did not differentiate patients with small cell lung cancer from patients with non small cell lung cancer and nonmalignant lung diseases. Bronchial lavage SCC Ag levels were significantly higher than serum SCC Ag levels.
