Insights

Metered-dose inhaler ipratropium bromide (IB) did not reduce hospital admissions for severe pediatric asthma exacerbations. This delivery method may be less effective than nebulizers for ipratropium bromide inhalation.

Area of Science:

  • Pediatric Emergency Medicine
  • Respiratory Medicine
  • Pharmacology

Background:

  • Ipratropium bromide (IB) with beta-agonists reduces pediatric asthma hospitalizations.
  • Metered-dose inhalers (MDIs) may shorten emergency department (ED) stays compared to nebulizers.
  • Effectiveness and safety of MDI-delivered IB with spacers in children are not well-established.

Purpose of the Study:

  • To evaluate the effectiveness and safety of metered-dose inhaler (MDI) administered ipratropium bromide (IB) in pediatric patients with acute asthma exacerbation.

Main Methods:

  • Prospective, non-randomized, observational study of pediatric patients (≥4 years) with severe asthma exacerbation.
  • Patients received IB via MDI with a spacer three times at 20-minute intervals.
  • Propensity score matching was used to control for confounding factors.

Main Results:

  • No significant difference in admission rates between the IB group (25.9%) and the non-IB group (31.5%).
  • Similar post-treatment modified pulmonary index scores in both groups.
  • One patient (1.0%) in the IB group experienced mild vomiting.

Conclusions:

  • MDI-delivered ipratropium bromide was ineffective in reducing pediatric asthma admission rates.
  • Potential for reduced efficacy compared to nebulized ipratropium bromide.
  • Further research needed to compare MDI and nebulizer delivery for IB in pediatric asthma.

Inhaled Medications01:23

Inhaled Medications

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: 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...

COPD: Management Using Bronchodilators and Corticosteroids

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...

Antiasthma Drugs: Methylxanthines

Theophylline, a member of the methylxanthine class of bronchodilators, has long been used in asthma management. While its exact mechanism of action is not fully understood, it is believed to have multiple effects on various cellular processes.
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...

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...
