a) The official (that is, generic) drug name is guaranteed to be unique, but they cannot be trademarked. That's one part of why drugs are typically marketed under names other than the official name ("Lipitor" is a market name, "atorvastatin" is the actual drug name).
b) Most patients don't know the names of the drugs they are taking, and what they do know are as often as not, not the official name, but a marketing name. Ask any doctor why they ask patients to bring their prescriptions with them to office visits (hint: because in m any cases, it's the only way to get an accurate picture of what a patient is actually taking.)
c) I don't follow this at all. It's a bad think that I know that the three drugs I take are a diuretic, a beta blocker, and an angiotensin receptor blocker?
I think it's interesting to compare drug naming with other medical interventions. We don't call a Laparoscopic Cholecystectomy a "gandalf" or "vartafoprodson." We use medically meaningful names. Why is "losartan" better than "angiotension receptor blocker 95-1" (first ARB approved in 1995)?
