Where do drug names come from?

Have you ever wondered how they name drugs? The actual name usually relates to the chemical compound involved, but the brand name – how do they come up with that?

Take some of my drugs, for example.

Cetirizine is the “science” name for Zyrtec. Why is cetirizine any harder to remember than Zyrtec? Okay, Zyrtec is easier to pronounce, and when I say it the millions the manufacturer paid in advertising pays off – I remember the ads. But Zyrtec isn’t exactly a warm and fuzzy name. It sounds very “science-like” which is probably a good thing when you’re naming a drug. But, where did the word come from?

How about another one? Fluticasone Propionate – that’s the “science” name for Flonaise. At least they start with the same letter.

Or how about Diphenoxylate Atropine? It’s otherwise known as Lomotil. I think Lomotil is definitely an improvement on the name, but still, not the word that instantly would pop into my mind if trying to name a product.

In my humble patient opinion, probably the most effective ad campaign from a drug company was for a drug called Nexium – again, who thought that up? But, in the ads, knowing that those of us that squeaked through high school chemistry can have a tough time with these names, the drug was referred to as “the purple pill.” Now, I can get my brain around that.

Ratner's Cheesecake

Here's another recipe from Toby! Thanks Toby......and I'll get the others posted soon! Ratner's Cheesecake and plain cookies Ratner's was a Jewish dairy restaurant in the lower East Side of Manhattan. This recipe, from my disintegrating, no longer in print Ratner's cookbook, is the closest I've ever gotten to reproducing the rich, heavy cheesecake my mother made when I was a kid.

Some good news about Pirfenidone

Below is a press release from Intermune, the company that makes Pirfenidone. They have essentially reviewed the various clinical trials going on, and decided that Pirfenidone is safe and well tolerated. That would pretty much go along with what we've observed in the HPS community as well. We have a few folks that have been on the drug since the late 90s and continue to do well. Of course, as a journalist, I do have to say consider the source - but at the same time, as someone in a Pirfenidone trial, it's good to know. Results of Comprehensive Safety Analysis of pirfenidone In IPF Patients Presented At European Respiratory Meeting - Analysis shows safety and tolerability of pirfenidone across four clinical trials - VIENNA, Sept. 14 /PRNewswire-FirstCall/ -- InterMune, Inc. (Nasdaq: ITMN ) today announced that the results of a comprehensive review of safety data from four clinical studies were presented at the 2009 European Respiratory Society Annual Congress in Vienna, Austria...

The next generation with Hermansky-Pudlak Syndrome

I'm so behind on posting about the trip to Puerto Rico. Since the episode of Mystery Diagnosis on Hermansky-Pudlak Syndrome ran right after we got home, it's been a little busy. These, however, are my favorite pictures from Puerto Rico. I know, not pretty senery etc - but these little guys and gals inspire me. They are the next generation of folks with HPS, and if we keep up the hard work, they will live better lives because of it. They motivate me.
