Abstract
Introduction
Extrafine formulation of beclomethasone/formoterol fixed combination (BDP/F pMDI HFA) is approved for both fixed maintenance and maintenance and reliever therapy (MART) of asthma, and recent data has proven that BDP/F pMDI HFA maintenance and reliever therapy is an effective alternative to other regimens.
Objective
This study aimed to assess the level of asthma control in a real-life setting in adult patients using extrafine BDP/F pMDI HFA fixed combination in a pressurized metered-dose inhaler (pMDI) as fixed maintenance dosing as well as maintenance and maintenance and reliever therapy. Additionally, we examined patients’ satisfaction with the inhaler device and compliance with therapy as essential factors determining asthma control.
Methods
This multicenter prospective non-interventional observational study lasted 4 months with 3 patient visits. We used the Asthma Control Questionnaire 7 (ACQ-7) to evaluate the degree of asthma control and Morisky Medication Adherence Scale (MMAS-4) to assess compliance. A self-developed questionnaire was used to assess satisfaction with the inhaler device.
Results
2179 patients using BDP/F pMDI HFA fixed combination as maintenance and reliever therapy or BDP/F pMDI HFA as maintenance therapy and SABA (short-acting beta2-agonist) as a reliever for at least 2 months were included. During the prospective follow-up, we observed an upward trend in the FEV1% (forced expiratory volume in 1 s) predicted values, improvement in the control of symptoms as indicated by a decline in the mean ACQ-7 score was noted (1.62 at Visit 1 vs. 1.21 at Visit 2 vs. 0.94 at Visit 3, p < 0.001) and increase in patients’ compliance (the number of patients that reported forgetting at times to take their medication was reduced from 49.7 % to 27.1 %, p < 0.001). At the same time, we noted a reduction in the number of as-needed doses used for symptom relief (p < 0.001). Most patients were satisfied with the pMDI, considered it easy and convenient to use, and preferred it to a dry powder inhaler (p < 0.001).
Conclusions
The use of extrafine BDP/F pMDI HFA as maintenance as well as reliever therapy seems to be associated with increased asthma control and better compliance to therapy.
期刊介绍:
Pulmonary Pharmacology and Therapeutics (formerly Pulmonary Pharmacology) is concerned with lung pharmacology from molecular to clinical aspects. The subject matter encompasses the major diseases of the lung including asthma, cystic fibrosis, pulmonary circulation, ARDS, carcinoma, bronchitis, emphysema and drug delivery. Laboratory and clinical research on man and animals will be considered including studies related to chemotherapy of cancer, tuberculosis and infection. In addition to original research papers the journal will include review articles and book reviews.
Research Areas Include:
• All major diseases of the lung
• Physiology
• Pathology
• Drug delivery
• Metabolism
• Pulmonary Toxicology.
