Whether Spiolto and Spiriva are their substitutes?

I understand that both drugs have a bronchodilator effect, similar to budesonide?
And which of these drugs is the safest, I mean, the best and safest when it comes to quick help with shortness of breath during covid? Do you have a cold

I used budesonide in doses of 800 days and 800 nights, but despite rinsing my mouth, I got thrush and after 12 days of use, throat irritation and side effects of itchy eyes and ears quickly occurred.

Can any of these drugs be used on an ad hoc basis during shortness of breath or should they all be used for several days? Are these steroids?

Hello, which of the drugs will seem to be the most appropriate or is the most used in the case of people who have not had lung problems. But after covid or a cold, they have a dry cough and lower lung capacity.
There is also budesonide, which I received, but which of these drugs has the least side effects and is best tolerated by people 30-40 years old
