Summary

Aripiprazole is metabolized by CYP2D6 and CYP3A4. Because of this, drug interactions can happen. I discuss specific examples in this episode.



Partial dopamine agonist activity and serotonergic activity make up a significant amount of aripiprazole's pharmacology.



Aripiprazole is classified as an antipsychotic and can be used in schizophrenia, bipolar disorder, and depression augmentation.



Aripiprazole can cause significant akathesia. I discuss this adverse effect on this episode.

Hey all, welcome back to the Real Life Pharmacology podcast. I'm your host, pharmacist, Derek Christensen.

0:06.4

Thank you so much for listening today. As always, go check out Real Life Pharmacology.com.

0:12.3

If you haven't already, snag your free 31-page PDF on the top 200 drugs. Great little study guide.

0:19.8

If you're looking to brush up on your skills,

0:21.6

remember a few things, or if you're preparing for board exams, pharmacology finals, things like that,

0:28.1

just great refreshers of things that commonly come up in practice and things that you may see

0:33.8

come up on exams as well. So the drug of the day today is aeropipyprosol.

0:41.1

A brand name of this medication is Abilify. This medication is classified as an antipsychotic.

0:50.4

Now any drug typically that's classified as an antipsychotic is going to have activity on dopamine receptors.

1:01.6

Now, Abilify, rarapriazole is slightly different in that it isn't quite as strong of a dopamine blocking agent at that D2 receptor as some of the other classically known antipsychotics, such as, you know, haloperidol or respiradone.

1:22.5

It's more of a partial agonist, so that mild stimulation, but it also blocks the dopamine 2 receptor

1:33.4

from being basically fully agonized or fully stimulated. And so if you remember from, you know,

1:43.1

pathophysiology and things like that.

1:45.0

Excessive dopamine is typically thought to be a significant component of causing symptoms of schizophrenia,

1:53.0

hallucinations, delusions, things of that nature.

1:57.0

So by, you know, blocking, reducing the activity of dopamine, it makes sense that it could potentially help those type of diagnoses.

2:07.9

In addition to that partial agonist at the D2 receptor, it's got some action on serotonin reupttake potentially, milder antihistamine type effect,

2:22.1

also milder alpha blocking effect compared to some other antipsychotics.

2:27.7

And we'll kind of touch on that a little bit in the adverse effect profile,

2:31.7

where it maybe differs from some of the other antipsychotics.

2:35.5

So uses. In clinical practice, I've certainly seen it for things like schizophrenia, bipolar disorder,

2:43.0

where we've got those hallucinations, delusions, a lot of those positive symptoms associated with schizophrenia, for example.
