When I was in school, it was really hard drilled into us about using 'correct' pronunciation of drugs and jargon. It was assumed (incorrectly so), that all pronunciations, used in that school, by that particular set of professors, were correct. In the real world, based upon geographic location and population, pronunciations vary.
e.g. platelet. We were taught plate-let. Others say plat-E-let.
It's like nail in head, when I hear someone use that hard 'E'. Unfortunately, the person that created the word platelet, isn't around to give us the intended correct pronunciation. So who knows?
I've met drug reps. trained by the same company, hawking the same drugs, pronounce the same drugs differently than their coworkers. Unless it obviously is some hybrid pronunciation, (like when I sing a song, I don't know the correct words for, so I make up the words), exercise caution and respect when correcting others.
