Asthma management is often poor due to guideline issues and incorrect inhaler use. Improving inhaler technology is key to better asthma control, especially for pressurised metered dose inhalers (pMDIs) and dry powder inhalers (DPIs).

Area of Science:

  • Pulmonary Medicine
  • Respiratory Care
  • Pharmacology

Background:

  • Asthma prevalence is increasing globally, yet it remains poorly controlled despite effective medications.
  • Key challenges include guideline limitations, poor patient adherence, incorrect inhaler technique, and inadequate treatment of peripheral airway inflammation.

Purpose of the Study:

  • To highlight the critical role of inhaler technology in improving asthma management.
  • To discuss the limitations of current asthma management strategies and the potential of improved inhaler devices.

Main Methods:

  • Review of current asthma management guidelines and their implementation challenges.
  • Analysis of patient adherence issues, focusing on inhaler device usage.
  • Comparison of pressurised metered dose inhalers (pMDIs) and dry powder inhalers (DPIs).

Main Results:

  • Most patients do not benefit fully from pMDIs due to incorrect usage.
  • Dry powder inhalers (DPIs) offer advantages like breath activation and ease of use.
  • Significant advancements in inhaled asthma medications are unlikely in the near future.

Conclusions:

  • Improvements in inhaler technology are essential for advancing asthma management.
  • Future inhaler devices must be user-friendly, ensure consistent dosing, and optimize drug delivery to central and peripheral airways.
