Summary

On this episode I discuss colchicine pharmacology, adverse effects, drug interactions, and pharmacokinetics.



Colchicine ultimately works by reducing the activity of neutrophils that help contribute to pain and inflammation associated with gout.



Colchicine does have some drug interactions with medications and grapefruit juice via CYP3A4.



The most common dose limiting side effect of colchicine is diarrhea.



Colchicine can be used as a potential alternative to NSAIDs or corticosteroids in the management of a gout flare.

0:37.2

talk about the drug of the day today, and that is going to be Colchazine.

0:42.4

Brand name of this medication is Colchris.

0:45.9

That's the most common brand name that I hear in clinical practice anyway.

0:51.7

And this medication does have a bunch of unique uses. However, 99% of the time,

1:01.4

the indication that I see this medication used for is gout. That is mostly what I'm going to focus on.

1:09.3

There's things like Mediterranean fever. There has been

1:13.7

potentially some evidence in reducing cardiovascular risk as a secondary prevention type agent.

1:22.2

I can't say at the time I'm creating this podcast that I'm real you know, real sold on the evidence and the risk versus

1:30.7

benefit of doing that. But that may be something that you see more evidence on going forward

1:37.9

in the future. But again, I'm going to focus mainly on that gout indication.

1:48.6

So mechanistically, how does it work?

1:59.8

It blocks beta tubuline polymerization into microtubules, which ultimately reduces the activation or activity of neutrophils.

2:03.6

Okay.

2:04.4

And in gout, remember, inflammation plays a huge role in the pain associated with a gout flare.

2:13.8

Nutrivils are really going to facilitate and exacerbate that inflammation and pain.

2:21.0

So again, by kind of reducing that activation, activity of those neutrophils,

2:28.4

we can help manage symptoms of a gout flare.
