Education: Naming drugs

You were asking who comes up with the drug names and what do they mean? 

A pharmaceutical company could come up with the name itself or they can spend a lot of money doing market research and they pay marketing companies (I have seen written $100,000-$700,000) to come up with names, as it is how they do marketing. 

Would you want to take a a drug called Shitola? 

I have no idea how they come up with the likes of extavia (sounds like a sugar substitute), tecfidera, lemtrada, tysabri etc. They are registered trade names and may be different in Europe verses USA.

I have some idea of the way the generic names are derived as I need to do it for our new drug VSN16. This was the sixteenth drug made by Cristina Visintin. We have another JW47 which was the forty seventh drug made by Justin Warne who are post-doc Chemists who work with us. 

I quite liked Qmuclofen to reflect its heritage QM & UCL but apparently it sounds too much like baclofen, which is cheap..apparently not good.

We need to come up with a generic name for the drug and there are rules to this. They are often picked to be difficult to say which makes it easy to forget when the trade name arrives. 

In early pre-clinical trials drugs are known by their code names 
e.g. FTY720. 

Then in phase II aand III they may be known by the name of the non-proprietary generic name in this case fingolimod

Then they get a trade name after registration in this case Gilenya

So if we look at the generic names they can tell us what the drug does or what is the target of the drug and this can be found by the STEM (typically the ending).

So fingolIMOD…..This means it is an Immune modulator another of an -IMOD drugs is laquinIMOD.

Ibudilast has the stem -AST..which is an anti-asthma drug it is also a PDE4 inhibitor some of which end in -RAM

These are registered with the Word Health Organisation and this costs $12000 and these are the generic names

The table has columns for the Generic Name Stem, a Stem Definition, and an Example. Each stem has hyphens at one or both ends of its text to show that it is found at the beginning, end, or in the middle of a generic name.

For example, the stem “-azepam” would be found at the end of a generic name, corresponds to the definition “Antianxiety agents (diazepam type)”, and Lorazepam as an example drug.

The stems calci- or -calci- are found at the beginning or middle of “Vitamin D analogues” such as calcipotriene and tacalcitol.

What are we going to call VSN16 either something that inhibits spasticity or something that binds to a target….but can’t tell you that yet.

Antibodies in preclinical studies are often known by the code on a 96 well plate. 

The columns are labelled 1-12 and the rows a-h. So 4F12 may be clones from the forth 96 well plate row f column 12. There is one antibody clone that was called FuJA and word on the street was that it meant f**k you JA, with JA being the initials of someone who had made an antibody against the target of FUJA, but they would not give it out so someone had to make one of their own.
I made a cell line called BCTL-1 (Big Chief Team Leader-One) MD2 made one called GP8 which was cell used to make a blood brain barrier.

If we look at anti CD20 antibobodies we have

You can see the stem mab telling you that they are monoclonal antibodies.

-xi- means chimeric so the antibody is part animal in the variable bit and the constant bit is human. (rituximab)
zu– is humanised, so the antibody is largely human and the antigen binding bits are animal (alemtuzumab, natalizumab, ocrelizumab)
u(mo)– is human. 

So there is more information such as the target tuzumab (tumor targeting antiboby), so for ocrelizumab we have ocreLI (immune system) ZU (humanised), MAB (monoclonal antibody), so would you pay someone to come up with OCRE…I guess some companies do:-)

  • Interesting… So it appears that fingolimod is fully based on these guidelines: the first part, fingol, stands for sphingosine derivatives, and you explained -il- and -mod already as immunomodulator. I have not seen on your list any explanation for Laquin- in laquinimod, but I bet quin there stands for a quinoline ring which the molecule contains.

  • However Siphonimod is also a sphingosine-one phosphate modulator wonder it this is related to siphoning money away.

    However you may be right the name of laquinimod is 5-chloro-N-ethyl-4-hydroxy-1-methyl-2-oxo-N-phenyl-1,2-dihydroquinoline-3-carboxamide an so I have learned because I don't think they are striving for un-pronouncable names but simply using STENs so they pay companies to come up with LA will the next one be called TI.

  • Wow…that post was downright impressive. Bravo, MouseDoctor. Now, I just have to wonder how much time med schools and pharmacy schools give their students to memorize that list. 🙂

    • They have to memorise more its amazing the amount of knowledge that meical students have to assimilate
