Is Adair a Metered-Dose Inhaler?
I cannot determine if "Adair" is a metered-dose inhaler because this medication name does not appear in any available medical literature, FDA drug databases, or clinical guidelines. The term "Adair" is not recognized as a standard pharmaceutical product name for any inhaler device.
Possible Explanations
Misspelling or Brand Name Variation: You may be referring to a medication with a similar name. Common inhaler medications include:
Regional or International Naming: Some medications have different brand names in different countries, and "Adair" may be a regional variant not covered in the provided evidence.
Key Distinction Between Inhaler Types
If you meant Advair, it's important to know:
- Advair Diskus is a dry powder inhaler (DPI) that does not require a spacer and is breath-activated 1
- Advair HFA is a metered-dose inhaler (MDI) that uses propellants to deliver medication and benefits from spacer use 1, 2
MDIs require coordination between actuation and inhalation, while DPIs are breath-activated and require the patient's inspiratory effort 1. MDIs benefit from spacers to improve drug delivery (10-20% lung deposition with spacer versus less without) and reduce oropharyngeal deposition 1, 2.
Clinical Recommendation
Please verify the exact spelling and formulation of the medication in question. If this is indeed "Advair," specify whether it is the Diskus (DPI) or HFA (MDI) formulation, as this fundamentally changes device technique, spacer requirements, and patient education needs 1, 2.
