Summary
On this episode of the Real Life Pharmacology Podcast, I cover topiramate pharmacology.
Topiramate is indicated for migraine prevention, seizures, and weight loss which are the most common uses that I see this medication used for.
Topiramate has carbonic anhydrase activity, so rarely, use of this drug may induce metabolic acidosis.
By far, the most common patient complaint I get with the use of topiramate is that it causes cognitive slowing or impairment.
I discuss important drug interactions on the podcast, be sure to check out my latest project which is a 200+ page book on managing drug interactions in primary care.

| 0:44.8 | going to start discussing topiramate, which is the drug of the day today. Brand name of this |
| 0:51.8 | medication is Topamax. Primary uses, I would say it's technically |
| 0:59.7 | classified as an anti-convulsant. I would say by far, probably the most common conditions I see |
| 1:06.9 | it used for. Definitely is migraine, probably the top of the list there. |
| 1:12.7 | Occasionally for seizures, also see it used in weight loss as well. |
| 1:19.0 | And if you remember, I've talked about, I think, a couple of weight loss drugs, |
| 1:23.9 | but Topiramate actually comes in combination as a brand name product called |
| 1:31.0 | Cusimia, and that's actually in combination with fentanymine. Mechanistically, this drug isn't |
| 1:41.7 | crazy well understood, and that's, you know, one of the reasons for that is it's got multiple possible mechanisms that it works through. |
| 1:52.4 | So one is that it helps to enhance GABA. |
| 1:56.6 | If you remember, GABA is an inhibitory neurotransmitter, so that may be one of the pathways |
| 2:02.8 | that it potentially helps with seizures and things like that. And same thing with blocking |
| 2:07.8 | voltage-gated sodium channels. That's also a purported mechanism there. And then it also |
| 2:15.6 | has carbonic anhydrase inhibitory action. |
