What is albuterol? Why does not having it render the entire list terrible? Could you elaborate in a way that inspires useful discourse?

It's a front-line medicine used for the treatment of asthma and COPD. As your sibling comment notes, it's on the list, just under its generic name.

Albuterol is also a generic name, just that it's USAN and different from INN.

> Albuterol is used to prevent and treat wheezing, difficulty breathing, chest tightness, and coughing caused by lung diseases such as asthma and chronic obstructive pulmonary disease (COPD; a group of diseases that affect the lungs and airways). Albuterol is in a class of medications called bronchodilators. It works by relaxing and opening the air passages to the lungs to make breathing easier.

It’s there under the name Salbutamol

Doesn't make it terrible, but I think Clonidine and Hydrocodone/acetaminophen should have been there too.

Acetaminophen is there under the equivalent name Paracetamol.

It's actually called Paracetamol in the rest of the world except USA. It's in the list.

I’m guessing that clonidine didn’t make it because it’s not pregnancy safe (yes there are probably tons of those on the list).

I think it's also because it treats things for which there are safer alternatives on the list (especially for reducing blood pressure).
