Physicochemical compatibility and stability of nebulizable drug admixtures containing Dornase alfa and tobramycin.
2012
The objective of this in-vitro study was to determine whether admixtures of the inhalation solutions Pulmozyme(®) (Dornase alfa) and either Bramitob(®) or Tobi(®) (both containing Tobramycin) are physicochemically compatible and to analyze the aerodynamic parameters of these admixtures. After mixing, test solutions were stored at room temperature and under ambient light conditions over a period of 24 h. Tobramycin concentrations were determined by using a fluorescence immunoassay. Stability of dornase alfa was determined by size-exclusion high performance liquid chromatography, ultraviolet spectroscopy, sodium dodecyl sulfate polyacrylamide gel electrophoresis and tentacle strong cation-exc…
Dose bridging data for mometasone furoate in once-daily fixed-dose inhaled combinations of mometasone furoate/indacaterol and mometasone furoate/ ind…
2021
Once-daily (o.d.) fixed-dose combinations of mometasone furoate/indacaterol acetate (MF/IND) and mometasone furoate/indacaterol acetate/glycopyrronium bromide (MF/IND/GLY), both delivered via the Breezhaler® device, are approved for the maintenance treatment of asthma. Across these fixed-dose combinations, while the doses of bronchodilators remain the same, the nominal doses of mometasone furoate in micrograms differ. This article presents the steps followed in bridging the mometasone furoate doses at the corresponding dose strengths in the mometasone furoate formulation delivered via the Twisthaler® and mometasone furoate/indacaterol acetate and mometasone furoate/indacaterol acetate/glyco…
Current and future pharmacologic therapy of exacerbations in chronic obstructive pulmonary disease and asthma.
2005
Exacerbations are an important cause of the morbidity and mortality associated with asthma and chronic obstructive pulmonary disease. Newer therapies include long-acting beta(2)-agonists, which are more effective than short-acting bronchodilators. Inhaled corticosteroids and, in asthma, leukotriene receptor antagonists may have roles in the early phase of exacerbation as an alternative to or added to oral prednisolone. In the future, combinations of long-acting beta(2)-agonists and anticholinergic bronchodilators may offer additive clinical benefits. However, although the treatment and prevention of exacerbations of chronic obstructive pulmonary disease and asthma have been improved by usin…
Indacaterol/glycopyrronium/mometasone fixed dose combination for uncontrolled asthma
2021
INTRODUCTION Asthma symptoms can be relieved through a maintenance treatment combining long-acting β2-agonist and inhaled corticosteroids (LABA/ICS). However, for patients with inadequately controlled asthma, the LABA/ICS combination might not be sufficient. Under these conditions, clinical guidelines recommend the administration of inhaled long-acting muscarinic antagonists (LAMA) as an add-on therapy to LABA/ICS to better control asthma and improve lung function. For nearly two decades, the only LAMA to be approved on the market has been tiotropium. AREAS COVERED We reviewed recent clinical studies evaluating the safety and efficacy of LABA/LAMA/ICS fixed dose combinations by searching Pu…
Occurrence of illicit drugs in two wastewater treatment plants in the South of Italy
2017
In this study the occurrence and the behavior of illicit drugs and their metabolites have been investigated for two wastewater treatment plants (WWTPs) (namely, WWTP-1 and WWTP-2) located in Sicily (island of Italy). Samples were analyzed for methamphetamine, cocaine (COC), 3,4-methylenedioxymethamphetamine (MDMA), methadone (METH), 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), 3,4-methylenedioxy amphetamine (MDA); 3,4-methylenedioxy ethylamphetamine (MDEA), 11-nor-9-carboxy-Î9-tetrahydrocannabinol (THC-COOH) and Benzoylecgonine (BEG). The BEG, COC, MOR and THC-COOH were found at the highest concentration in both WWTPs. The Wastewater-based epidemiology calculation for BEG, COC…
Intraorifice sealing ability of different materials in endodontically treated teeth.
2010
Objectives To evaluate Cavit TM G, ProRoot TM MTA and Tetric® EvoFlow as intraorifice barriers to prevent coronal microleakage in root canal treatment. Study design Forty-two human single rooted teeth were divided randomly in three experimental groups of 10 specimens each and two control groups. The experimental groups were prepared with hand instrumentation and cold lateral condensed technique of the gutta-percha. Four millimetres of coronal gutta-percha were removed and replaced by one of the following filling materials: Cavit TM G, Tetric® EvoFlow or ProRoot TM MTA. In the experimental groups, leakage was measured by the concentration of leaked glucose in the apical reservoir at 1, 7, 30…
Retrograde filling material in periapical surgery: a systematic review
2021
Background Periapical surgery focuses on the treatment of teeth with persistent periapical lesions when orthograde root canal treatment fails. Although MTA® is the gold standard material for retrograde filling, Biodentine® - a tricalcium silicate-based cement - has been proposed in order to resolve several of its limitations. A systematic review has been carried out to compare the physicochemical properties of Biodentine® versus MTA® as root-end filling material in periapical surgery. Material and Methods An electronic search was conducted by two independent examiners during March 2020 in the Cochrane, PubMed-MEDLINE and Scopus databases. In addition, a manual search was made in specialized…
An adaptive multimeme algorithm for designing HIV multidrug therapies.
2007
This paper proposes a period representation for modeling the multidrug HIV therapies and an Adaptive Multimeme Algorithm (AMmA) for designing the optimal therapy. The period representation offers benefits in terms of flexibility and reduction in dimensionality compared to the binary representation. The AMmA is a memetic algorithm which employs a list of three local searchers adaptively activated by an evolutionary framework. These local searchers, having different features according to the exploration logic and the pivot rule, have the role of exploring the decision space from different and complementary perspectives and, thus, assisting the standard evolutionary operators in the optimizati…
In vitro antibacterial activity of endodontic sealers
2004
Summary Objectives To evaluate the antibacterial activity of four endodontic sealers: one epoxy resin sealer (AH Plus), two zinc oxide eugenol (ZOE)-based sealers (Endomethasone, Pulp Canal Sealer), and one sealer containing both ZOE and orthophenilphenol (Vcanalare). Methods A direct contact test (DCT) was performed. A 10 μl suspension of Enterococcus faecalis was placed on the test material 20 min, 24 h and 7 days after mixing. Bacteria were allowed to directly contact the sealers for 1 h at 37 °C. Bacterial growth was then spectrophotometrically measured every 30 min for 7 h, and again after 24 h as well. Results All freshly mixed sealers showed complete inhibition of bacterial growth. S…
Use of ICS in COPD: From Blockbuster Medicine to Precision Medicine
2017
Chronic obstructive pulmonary disease (COPD) is a major cause of mortality worldwide, whose burden is expected to increase in the next decades, because of numerous risk factors, including the aging of the population. COPD is both preventable and treatable by an effective management including risk factor reduction, prevention, assessment, and treatment of acute exacerbations and co-morbidities. The available agents approved for COPD treatment are long-acting or ultra-long-acting β2-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) bronchodilators, as well as inhaled corticosteroids (ICS) in combination with LABAs. ICS use has been restricted only to selected COPD patients by th…
