Background: Short-acting β2-agonists (SABA) overuse is associated with asthma morbidity and mortality. The SABA use IN Asthma (SABINA) program aimed to describe the global use of SABA in patients with asthma. SABINA III study was a cross-sectional study covering 24 countries.
Methods: We performed statistical analysis of the Russian population (618 patients recruited in 12 centers) from the SABINA III study. In this study in patients aged ≥12 years, data on disease characteristics and asthma treatments were collected using real-time electronic case report forms. Patients were classified by asthma severity and control according to the 2017 GINA. All variables (asthma severity and control, number of severe exacerbations, SABA and other medications use) were analyzed descriptively only, no hypothesis was tested.
Results: Majority of the study population consisted of patients with moderate/severe asthma (78.5%), while mild asthma was seen in 21.5%. Asthma was uncontrolled in 36.1% of patients and partly controlled in 33.5%. More than 80% of patients were treated with ICS/LABA fixed-dose combination. Almost half of all patients (47.0%) had at least 1 severe exacerbation in the previous 12 months. SABA over-prescription (≥3 canisters per year) was seen in 37% of patients. The frequency of SABA over-prescription was similar in patients with mild (35%) and moderate/severe (38%) asthma. SABA was purchased over-the-counter (OTC) in the past 12 months by 30.1% of all patients, and 14% purchased ≥3 canisters of SABA per year. About 91% of patients who purchased SABA OTC already received prescriptions for SABA, of whom 59% were prescribed ≥3 canisters per year.
Conclusion: Russia is seeing very high level of SABA over-prescription. This is potentially associated with poor asthma control and frequent severe exacerbations. Over-prescription may serve as the main cause for SABA overuse in Russia. To reduce SABA overuse and improve overall asthma control in Russia, it is necessary to educate not just the patients but also the doctors, while actively implementing up-to-date asthma treatments.

Patient experience, understanding and self-management of asthma attacks: a qualitative study.
J Asthma
January 2025
Nottingham Asthma Centre, Nottingham Respiratory Research Unit, University of Nottingham, UK.
Rationale: Asthma attacks (AA) are potentially life-threatening complications of asthma associated with high levels of morbidity, mortality and rising healthcare costs. Patient experience, impact and understanding of AA is poorly described in the literature. Enhanced understanding will identify unmet needs in asthma care and support the development of improved personalized strategies for managing and preventing attacks.

Article Synopsis
- Asthma is a prevalent noncommunicable disease associated with significant mortality, particularly in low- and middle-income countries like the Philippines, where short-acting beta-agonists (SABAs) are often overused, leading to health risks.
- The review highlights the need for improved asthma management strategies, including the use of inhaled corticosteroid-formoterol combinations, patient education on inhaler use, and adherence to medication to prevent severe outcomes.
- Recommendations for better asthma care involve enhancing access to essential medications, implementing treatment algorithms, and developing multidisciplinary team approaches for primary care providers to improve patient outcomes.

Purpose: Asthma is affecting 4-5% of all adults (10% of children) in Germany, ≥ half are inadequately controlled. In 2019 up to 54 thousand patients suffered from severe uncontrolled asthma, 52% were treated/co-treated by pneumonologists. 45% of them had continuous oral corticosteroid (OCS)- and short-acting β2-agonist (SABA) overuse for ≥2 years.

Article Synopsis
- Over-reliance on Short-Acting Beta-Agonists (SABA) leads to poor asthma control and increased risks of exacerbations and death, highlighting the need for intervention.
- The study evaluated the Reliever Reliance Test (RRT), a tool designed to help patients self-assess and change their behavior related to SABA usage.
- Results showed that 82% of participants were at medium-to-high risk for SABA over-reliance, 73% reported SABA overuse, and 75% intended to discuss their treatment with a doctor, indicating that the RRT effectively raised awareness and facilitated discussions about asthma management.
Short-acting β-agonist Prescription Patterns in Patients with Asthma in the Philippines: Results from SABINA III.
Acta Med Philipp

Objective: As asthma is a chronic inflammatory disease of the airways, anti-inflammatory treatment should be positioned at the forefront of guideline-directed asthma care. However, patients tend to rely on short-acting β-agonists (SABAs) for rapid-onset symptom relief. The impact of SABA overuse and associated clinical outcomes have been investigated extensively in Europe and North America.
