It appears that taking inhalations for Asthma breaks the fast because it is a solution that reaches the throat, and therefore it will undoubtedly reach the stomach. If the fasting person is in need of using such a medicine during the day, in the same way a patient is in need of taking a medicine (either by drinking or eating it), he is allowed to break the fast and make up for each day he broke the fast. 

We mentioned that this is what appears to be because the texts of scholars all agree that any solution that reaches the throat is considered as a solution that reaches the stomach, and anything that reaches the stomach deliberately by mouth breaks the fast.

As regards our Mathhab (methodology), all the Muftis in Islamweb belong to Ahlus-Sunnah Wal-Jamaa'h in creed and in subdivisions (branches).  The rulings in Islamweb are not bound to any particular school; rather they are given according to the most preponderant answers of the scholars based on Islamic jurisdiction evidence.

Allaah Knows best.
