Another item from my search engine slush pile – “compare Atrovent inhaler to Clenil Modulite”.
Forget it, you can’t.
Why? Because they are totally different drugs, working in completely different ways. There is no basis for comparison.
Atrovent is a long-acting bronchodilator, while Clenil Modulite is a steroid inhaler, the CFC-free replacement for earlier versions of Beclometasone dipropionate inhalers – you cannot compare them because there is nothing to compare.
It’s like trying to compare the QE2 to the Ark Royal – both are ships, but have completely different functions which cannot be compared. You can only usefully compare like with like – comparing apples to oranges is futile.
