Background: COPD patients often require multiple therapies to enhance their lung function and reduce their symptoms in exacerbations. This study aimed to investigate the relative effects of combination adjunctive nebulized furosemide and salbutamol therapy versus single agent treatment in COPD patients.
Methods: Sixty-nine COPD patients were randomly divided into two groups. The first group (G1, 34 cases) received salbutamol in their first episode. The second group (G2, 35 cases) received furosemide in their first episode. Spirometry indices (FEV1, FVC, and FEV1/FVC), mMRC and BORG (COPD assessment) were assessed and recorded for all patients.To study the efficacy of combination adjunctive therapy, in 2nd episodes, the nebulized furosemide was added to nebulized salbutamol in the G1, and nebulized salbutamol was added to nebulized furosemide in G2. The aforementioned indices were then re-assessed.
Results: The mean age was (64.92 ± 11.71 years, 55% males. The use of nebulized furosemide and salbutamol as single agents slightly improved the spirometeric parameters, but it was not noteworthy compared to the significant improvement of the FEV1, FVC, FEV1/FVC, mMRC, and Borg parameters with combination therapy (-value< 0.001). In the first episode, there was no difference in spirometeric indices, between groups (-value > 0.1), so furosemide is considered as effective as nebulized salbutamol. Also, the results of sequential drugs administration, in the two groups was similar.
Conclusion: Conjunction of nebulized furosemide and salbutamol is more effective than single therapy and can be considered as preferred drug regimen without any reported side effect in the treatment of COPD.

Article Synopsis
- * The technique effectively produces spherical composite particles that dissolve better in water compared to traditional crystalline drugs, offering potential improvements in how medications work in the body.
- * Despite some challenges like needing a continuous water supply and managing solvent solubility, this method stands out for its flexibility and ability to create uniform particles, marking a significant step forward in drug formulation and delivery.

Objectives: Respiratory failure secondary to COVID-19 is associated with morbidity and mortality. Current anti-inflammatory therapies are effective but are given systemically and have significant side effects. Furosemide has anti-inflammatory properties, can be administered by inhalation, and is inexpensive.

Introduction: Obstructive lung diseases (OLDs) such as asthma and chronic obstructive pulmonary disease are major global sources of morbidity and mortality. Current treatments broadly include bronchodilators such as beta agonists/antimuscarinics and anti-inflammatory agents such as steroids. Despite therapy patients still experience exacerbations of their diseases and overall decline over time.

Background: Chronic obstructive pulmonary disease (COPD) is one of the most common chronic illnesses in humans. Among both oral and intravenous diuretics, nebulizing furosemide (Lasix) is the most commonly used agent. The purpose of this study was to ascertain the therapeutic effects of nebulizing furosemide compared with placebo in the treatment of COPD using a systematic review and meta-analysis of clinical trials.
