Brand name pharmaceuticals are sort of a different thing. Brand names must comply with the naming guidelines of the FDA, European Medicines Agency, and HealthCanda simultaneously. In practice, this makes it tricky to use actual words. So my companies adopt an 'empty vessel' naming approach. The empty vessels are nonsense words that (1) invoke an emotion (wegovy is a good example), (2) can be trademarked, and (3) it can survive brand pressure.
