Summary

On this podcast episode, I discuss meperidine pharmacology, adverse effects, pharmacokinetics, drug interactions, and much more!



Meperidine is an opioid that is seldom used due to neurotoxicity. I describe how this can happen in this podcast episode.



Meperidine has numerous drug interactions and using a CYP3A4 inhibitor may increase the risk for toxicity.



Seizures are a risk with meperidine due to its neurotoxic metabolite normeperidine. I discuss this further in this podcast episode.

myperidine. Now now this is definitely an older

when i first started practice in 2009 i saw this medication a little bit. On a positive note, I can't recall really the last

time I've seen Mapyradine used. It's been quite some time. So that is a good thing because we've

1:07.3

definitely got some warnings and potential adverse effects associated with this medication.

1:13.6

So first and foremost, myperidine is an opioid used in pain management or can potentially be used in pain management.

1:22.6

Just as a reminder, an opioid drug that binds opioid receptors.

1:30.6

And when that binding occurs, that action leads to essentially blocking the pain signals

And then obviously that interpretation of your brain saying that hurts,

the opioids and myperidine block that pathway.

1:52.5

So ultimately this reduces perception and response to pain.

2:00.2

Meparidine dosing, it's in the neighborhood of 50 to 150 milligrams.

You know, I.M., subcue, oral, these are all possible options, and can be given IV as well.

2:13.6

One additional indication that you may see a peridine used for, it's kind of a unique one,
