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…
Which factors affect the choice of the inhaler in chronic obstructive respiratory diseases?
2015
Inhalation is the preferred route of drug administration in chronic respiratory diseases because it optimises delivery of the active compounds to the targeted site and minimises side effects from systemic distribution. The choice of a device should be made after careful evaluation of the patient's clinical condition (degree of airway obstruction, comorbidities), as well as their ability to coordinate the inhalation manoeuvre and to generate sufficient inspiratory flow. These patient factors must be aligned with the specific advantages and limitations of each inhaler when making this important choice. Finally, adherence to treatment is not the responsibility of the patient alone, but should …
What drives inhaler prescription for asthma patients? Results from a real-life retrospective analysis
2020
Abstract Background The choice of inhaler device for asthma patients depends upon multiple attributes. We investigated factors that may drive general practitioners (GPs) and respiratory specialists in the prescription of inhaler devices for asthma patients who initiated inhalation therapy. Methods We retrospectively analysed prescriptions by GPs and respiratory specialists to asthma patients commencing inhaled corticosteroid/long-acting β2-agonist combination therapy available as both pressurised metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs). Patient characteristics were compared by device and multivariate analysis was used to model the likelihood of receiving a pMDI as oppos…
Eligibility for treatment with omalizumab in Italy and Germany.
2013
Summary Omalizumab is an add-on therapy for patients with uncontrolled severe allergic asthma. In Europe, patients must fulfil a number of additional criteria to become eligible for omalizumab therapy, creating a challenge for epidemiology studies to quantify the potential patient pool. Thus, and in the absence of robust data, the number of omalizumab-eligible patients has remained unclear. To assess eligible patient numbers, a chart-audit design approach was employed to measure epidemiology variables based on patient-level data. 770 patient charts were reviewed in designated towns in Germany and Italy, in collaboration with >200 primary care physicians (PCPs) and respiratory specialists (R…
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…
Changes in radiological protection and quality control in Spanish dental installations: 1996-2003.
2008
Introduction: The European Union has established specific directives concerning radiological protection which are obligatory for member States. In addition, all Spanish dental clinics with radiological equipment are required to have an annual quality control check. Objective: To analyze the effect of new European legislation on dental radiological practice in Spain and to determine whether it has resulted in lower doses being administered to patients. Material and Methods: A total of 10,171 official radiological quality control reports on Spanish dental clinics, covering 16 autonomous regions, were studied following the passing of Royal Decree 2071/1995 on quality criteria in radiodiagnosti…
Discrimination of Radiation Quality Through Second Harmonic Out-of-Phase cw-ESR Detection
2014
The ability to discriminate the quality of ionizing radiation is important because the biological effects produced in tissue strongly depends on both absorbed dose and linear energy transfer (LET) of ionizing particles. Here we present an experimental electron spin resonance (ESR) analysis aimed at discriminating the effective LETs of various radiation beams (e.g., 19.3 MeV protons, 60Co photons and thermal neutrons). The measurement of the intensities of the continuous wave spectrometer signal channel first harmonic in-phase and the second harmonic out-of-phase components are used to distinguish the radiation quality. A computational analysis, was carried out to evaluate the dependence of …
Use of molecular topology for the prediction of physico-chemical, pharmacokinetic and toxicological properties of a group of antihistaminic drugs
2002
We used molecular connectivity to search mathematical models for predicting physico-chemical (e.g. the partition coefficient, P), pharmacokinetic (e.g. the time of maximum plasma level, and toxicological properties (lethal dose, LD) for a group of antihistaminic drugs. The results obtained clearly reveal the high efficiency of molecular topology for the prediction of these properties. Randomization and cross-validation by use of leave-one-out tests were also performed in order to assess the stability and the prediction ability of the connectivity functions selected.
Aza-isoindolo and isoindolo-azaquinoxaline derivatives with antiproliferative activity
2015
Abstract Three new ring systems, pyrido[2′,3′:3,4]pyrrolo[1,2- a ]quinoxalines, pyrido[3′,2′:3,4]pyrrolo[1,2- a ]quinoxalines and pyrido[2′,3′:5,6]pyrazino[2,1- a ]isoindoles, were synthesized through an aza-substitution on the already active isoindolo-quinoxaline system and in particular in the position 7 or 4 of the isoindole moiety and in position 5 of the quinoxaline portion. All new compounds were screened by the National Cancer Institute (Bethesda, MD) against a panel of 60 human tumor cell lines. Biological results of the most active derivatives, with pGI 50 values between 7.09 and 7.27, confirmed the importance of the presence of methoxy substituents for biological activity. The ant…
