There are whole consultancies around picking drug names. The name isn't supposed to make an actual claim about effectiveness--you can't call it "cancercurazine"--but they often try for something vaguely suggestive: Viagra sounds like it makes you 'vital', Wellbutrin makes you feel well, Zyban keeps you away from nicotine, etc. I've heard--but can't find a source saying--that this is why varenicline is sold under two different names: someone felt like 'champix' was too suggestive.
