These studies suggest that while inhaler adherence and technique are often problematic, the Breezhaler inhaler is preferred by patients and suitable for a range of disease severities, but they do not provide specific guidance on the frequency of inhaler use.

Frequency of Inhaler Use: Insights from Recent Research
Recommended Inhaler Usage Frequency
Inhalers are a critical component in the management of respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). The recommended frequency of inhaler use can vary depending on the specific medication and the patient's condition. For instance, in a clinical trial involving the use of ipratropium bromide or a placebo, participants were instructed to use the inhaler as two inhalations three times daily. This regimen highlights a common prescription pattern for maintenance inhalers, which are typically used multiple times a day to manage chronic symptoms.
Adherence to Prescribed Inhaler Regimens
Despite clear instructions, adherence to prescribed inhaler regimens can be inconsistent. In the same clinical trial, while 73% of participants reported using the inhaler three times daily, objective data from a monitoring device revealed that only 15% actually adhered to this frequency. This discrepancy underscores the challenges in ensuring patients follow their prescribed inhaler schedules accurately.
Common Errors in Inhaler Use
Errors in inhaler technique are prevalent and have persisted over the past 40 years. A systematic review identified the most frequent errors with metered-dose inhalers (MDIs) as issues with coordination, speed and depth of inspiration, and failure to hold breath post-inhalation. Similarly, for dry powder inhalers (DPIs), common mistakes included incorrect preparation, not fully exhaling before inhalation, and not holding breath after inhalation. These errors can significantly impact the effectiveness of the medication.
Patient Handling and Preferences
The ease of use and patient preference for different inhalers can also influence adherence and effectiveness. A study comparing two single-dose dry powder inhalers, Breezhaler and HandiHaler, found that after seven days of use, over 77% of patients could use both inhalers correctly. However, 61% of patients preferred the Breezhaler over the HandiHaler, suggesting that patient preference can play a role in the successful management of COPD.
Conclusion
The frequency of inhaler use is typically prescribed based on the specific medication and patient needs, often involving multiple daily doses. However, adherence to these regimens is frequently suboptimal, with many patients not using their inhalers as often as prescribed. Additionally, common errors in inhaler technique persist, highlighting the need for improved patient education and training. Understanding patient preferences and ensuring the ease of use of inhalers can also enhance adherence and treatment outcomes.
