Insights

For children and adolescents with asthma uncontrolled by inhaled corticosteroids (ICS), long-acting beta-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) offer greater lung function improvement than leukotriene receptor antagonists (LTRAs). All treatments show comparable safety profiles.

Area of Science:

  • Pediatric Pulmonology
  • Pharmacology
  • Respiratory Medicine

Background:

  • Asthma management in children and adolescents is challenging, with many experiencing uncontrolled symptoms despite inhaled corticosteroid (ICS) therapy.
  • Selecting appropriate add-on pharmacotherapy for persistent asthma in this age group remains a clinical difficulty.

Purpose of the Study:

  • To compare the efficacy and safety of long-acting beta2-agonists (LABAs), leukotriene receptor antagonists (LTRAs), and long-acting muscarinic antagonists (LAMAs) as add-on treatments to ICS in pediatric asthma patients (4-17 years).

Main Methods:

  • A literature search identified 29 studies, including 21 randomized controlled trials (RCTs) of LABAs, 2 RCTs of LAMAs (tiotropium), and 4 RCTs of LTRAs (montelukast) as add-on therapy to ICS.
  • Studies focused on efficacy (lung function, exacerbations) and safety (adverse events).

Main Results:

  • Tiotropium (LAMA) and LABAs demonstrated greater lung function improvements compared to LTRAs when added to ICS.
  • Tiotropium showed a reduced risk of exacerbations requiring oral corticosteroids.
  • LABAs, LTRAs, and LAMAs exhibited comparable safety profiles to placebo regarding adverse events.

Conclusions:

  • LABAs and LAMAs provide superior lung function improvements compared to LTRAs as add-on therapy to ICS in pediatric asthma.
  • All three add-on options (LABAs, LTRAs, LAMAs) possess similar safety profiles in children and adolescents with asthma.

Antiasthma Drugs: Leukotriene Modifiers

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: β2-Adrenoceptor Agonists

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...

Drugs Used in Lower Respiratory Disorders: Overview

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...

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

Antiasthma Drugs: Muscarinic Receptor Antagonists01:20

Antiasthma Drugs: Muscarinic Receptor Antagonists

Muscarinic receptor antagonists, also known as antimuscarinic agents, are a class of bronchodilators used to treat asthma, although they are more commonly used to treat COPD. They work by inhibiting the action of acetylcholine (ACh), a neurotransmitter, on muscarinic receptors found in the airways.
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...
