Larazotide

How it works

Designed to close tight junctions, the seals between gut cells that gluten pries open in celiac disease, so the lining stays shut.

What it's made of

8 amino acids (GGVLVQPG) designed to close the junctions between gut cells. In the lab it curbed the opening caused by gluten and by a piece of cholera toxin.

What it's for

Prescribed for

Nothing.

Sold as

It closes the “leaky gut”: a pill so gluten can't slip through.
