Antiasthma Drugs: β2-Adrenoceptor Agonists01:25

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...

Antiasthma Drugs: Leukotriene Modifiers

2.2K
Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.
Leukotriene modifiers work through two distinct mechanisms:

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

2.4K
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
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...

Asthma-I: Introduction

3.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Summary

Negative affect in children and parents impacts asthma control and school absence. Medication adherence affects asthma treatment but does not explain the link between negative affect and symptoms.

Area of Science:

  • Pediatric Pulmonology
  • Child Psychology
  • Behavioral Medicine

Background:

  • Negative affect, including depression, is linked to asthma control.
  • The specific influence of negative affect on pediatric asthma control remains unclear.

Purpose of the Study:

  • To determine if negative affect and medication nonadherence predict poor asthma symptom control in children.
  • To investigate if medication adherence mediates the relationship between negative affect and asthma control.

Main Methods:

  • 104 children (8-18 years) with asthma using metered-dose inhalers participated.
  • Children and parents reported symptoms and affect; adherence was electronically monitored.
  • Health events were recorded to validate symptom reports.

Main Results:

  • Child and parent negative affect scores predicted asthma symptom scores and school absence.
  • Medication adherence predicted prednisone bursts but not subjective symptoms.
  • Nonadherence did not explain the negative affect-symptom relationship; parent affect predicted prednisone bursts independently.

Conclusions:

  • Negative affect and medication adherence distinctly influence pediatric asthma control.
  • Patient and parent affect may affect the accuracy of asthma symptom perception.
