Background:
Monoclonal antibodies (mABs) have become available to treat more efficiently patients with severe uncontrolled asthma (SUA). However, the use of mABs is lower than expected given the prevalence of SUA, with significant disparities in the use of these treatments.
Objective:
To evaluate the proportion of patients with SUA treated with mABs in Spain, and to analyze some of the factors that could determine these prescription patterns.
Methods:
An analysis was performed on the data provided from the Hospitals National Health System (NHS) 2018 catalogue where Chest Diseases Department and a Hospital Pharmacy were available. Random sampling was performed to determine the sample size, stratifying proportionally by geographic area and hospital level. Characteristics of the participating sites, as well as the prescribing of mABs were collected, which included geographic area, hospital levels, prescribing medical specialities, types of clinics, and mABs prescribed.
Results:
Data from 90 hospitals were analyzed (Response rate 64.3%). Level 4 hospitals, the Canary Islands geographical area, and the presence of a high complexity Asthma Healthcare Unit (ACU) were associated with a higher probability that the SUA was treated with mABs.
Conclusion:
The map of the prescribing of mABs for SUA in Spain shows a significant variation by geographic area, hospital level, type of clinic, and the accreditation level of the ACUs. At the current time, there appears to be significant under-prescribing of these treatments.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce...
01:20Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
