COPD: Management Using Bronchodilators and Corticosteroids01:26

COPD: Management Using Bronchodilators and Corticosteroids

1.2K
Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Inhaled Medications

1.1K
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

2.1K
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Drugs Used in Lower Respiratory Disorders: Overview

1.6K
Lower respiratory tract disorders present challenges that often require skilled and nuanced approaches for effective management. Common ailments, such as asthma and chronic obstructive pulmonary disease (COPD), have prompted the development of intricate treatment strategies involving bronchodilators and anti-inflammatory drugs, each tailored to ease breathing and revitalize the lungs.
Bronchodilators, the first step of respiration enhancement, come in various forms, each with its own mechanism...

Antiasthma Drugs: β2-Adrenoceptor Agonists

2.1K
Bronchodilators are critical in managing asthma, a chronic respiratory condition characterized by airway constriction due to inflammation and hyper-reactivity. Specifically, bronchodilators ease this constriction by relaxing the bronchial muscles, facilitating easier breathing.
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...

Area of Science:

  • Pharmaceutical technology
  • Respiratory medicine
  • Medical device engineering

Background:

  • Inhaled bronchodilators and corticosteroids are widely used for respiratory conditions.
  • Diverse production systems, including jet and ultrasound nebulizers, exist for these medications.
  • Optimizing nebulizer performance is crucial for effective drug delivery.

Purpose of the Study:

  • To compare the efficiency of jet and ultrasound nebulizers for inhaled medications.
  • To identify optimal combinations of nebulizer type, drug, residual cup, and loading volume for maximizing aerosolization.
  • To understand how environmental conditions affect nebulizer performance.

Main Methods:

  • Evaluated jet nebulizers (Invacare, Sunmist, Maxineb) with varying residual cups and volumes.
  • Assessed ultrasound nebulizers (GIMA, OMRON, EASY NEB II) with different volumes and mask/inlet configurations.
  • Analyzed the impact of factors like drug, nebulizer design, residual cup, and loading volume on aerosolization.

Main Results:

  • Both inhalation and ultrasound processes showed significant differences based on tested factors.
  • Jet nebulizer performance was influenced by residual cup, drug, nebulizer, and loading volume.
  • Ultrasound nebulizer performance was primarily affected by nebulizer type, drug, and loading volume.

Conclusions:

  • Specific drug-nebulizer-volume combinations were identified as optimal for both jet and ultrasound systems.
  • For jet nebulizers, PULMICORT, MAXINEB, cup J, and 6 ml loading were favored.
  • Ultrasound nebulizer optimization involved ZYLOREN, MAXINEB, and a 4 ml load.
