The Genuair Inhaler: A Breath-Actuated DPI
Understanding what type of inhaler is Genuair starts with its classification as a Dry Powder Inhaler (DPI). Unlike metered-dose inhalers (pMDIs), which use a propellant, DPIs like the Genuair rely on the patient's inhalation to deliver medication. The Genuair is specifically a breath-actuated, multi-dose DPI, meaning it automatically releases a dose when the patient inhales forcefully and deeply. Its multi-dose design eliminates the need for individual capsule loading.
Key Features of the Genuair Inhaler
Several features of the Genuair contribute to its ease of use, particularly for patients with COPD.
- Multi-sensory Feedback: Visual and acoustic cues confirm a successful dose. The control window changes color, and a click is heard during inhalation.
- Dose Counter: A visible indicator shows remaining doses, and a red strip signals when the inhaler is nearly empty.
- Lock-out Mechanism: The device prevents use after all doses are delivered.
- Anti-Double-Dosing: A safety feature prevents the release of a second dose.
- Medium Airflow Resistance: The design accommodates varying lung capacities in patients with moderate to severe COPD.
Medications Delivered by Genuair
The Genuair is used for long-term maintenance treatment of COPD, not for acute symptoms or asthma. Medications delivered include:
- Aclidinium bromide: A LAMA that relaxes airway muscles.
- Aclidinium bromide and formoterol fumarate: A combination of a LAMA and a LABA for extended bronchodilation.
Comparison of Genuair with Other Inhaler Types
The table below compares the Genuair DPI with other common inhaler types based on features like dose format, user action, and feedback.
| Feature | Genuair (DPI) | HandiHaler (DPI) | Pressurized Metered-Dose Inhaler (pMDI) |
|---|---|---|---|
| Dose Format | Multi-dose, pre-loaded | Single-dose capsules loaded individually | Pressurized canister |
| User Action | Breath-actuated, inhale forcefully and deeply | Capsule must be loaded and pierced, then two deep inhalations typically required | Requires coordination of pressing canister and inhaling simultaneously |
| Feedback | Visual (color window) and audible (click) | Audible capsule vibration | No integrated user feedback |
| Ease of Use | Considered easy to use; less training required and fewer errors compared to other devices in studies | More manual steps and can be prone to dose preparation errors | Can be difficult for some patients due to hand-lung coordination requirements |
| Resistance | Medium resistance | High resistance | No resistance |
| Cleaning | No cleaning required; disposable | Capsule chamber may need cleaning | Regular cleaning may be required for the mouthpiece |
How to Use the Genuair Inhaler Correctly
Proper technique is crucial for effectiveness. The Genuair simplifies the process, which generally involves preparing the dose, exhaling fully away from the mouthpiece, inhaling quickly and deeply through the mouthpiece until a click is heard, holding your breath, checking the control window to confirm the dose was taken, and replacing the cap. You can find detailed instructions and videos from sources like Asthma + Lung UK.
Conclusion
The Genuair inhaler is a multi-dose, breath-actuated dry powder inhaler designed to improve the ease and reliability of medication delivery for conditions like COPD. Its features, including sensory feedback and ease of operation, help reduce user errors and contribute to better patient outcomes. Proper training from a healthcare professional is always recommended to ensure correct use.
