Post Octreotide - vasoconstrict or vasodilate?

I thought that octreotide vasoconstricts splanchinic vessel but in FA2015 p.379, it is stated "inhibits actions of many splanchnic vasoconstriction hormones."
What's right?

Well it's used in situations like esophagela varices to stop bleeding as you may probably already know. If the hormones are vasodilating the splanchnic vessels octreotide will inhibit those hormones. It will pretty much inhibit any hormone it comes in contact with. As you can see there the action is indirect; by inhibiting hormones that vasoconstrict the splanchinic vessels, it ends up vasodilating those vessels.

So it really depends at the location and the hormone it's inhibiting.

This was mentioned in the "Corrections" PDF released by the publisher of First Aid. I tried to post the link, but I'm not sure what happened. I might not have enough account activity to post links yet? Who knows?

Whenever I try to post a link it needs moderator approval. Just do a Google search for it. You can find it really easy.

You should update every correction in that document to your review book. There is only a handful of corrections, so it won't take long and it might help with your study prep.

Good luck!
