Another potential issue: Most of the studies with sugammadex have been done with Zemeuron, a muscle relaxant also made by Organon.
Instead of targeting the receptors the muscle relaxants hit, sugammadex is a big carbohydrate molecule that binds to the muscle relaxant itself.
On the tape, Kevorkian injects muscle relaxant into Youk's arm to stop his breathing, and then injects potassium chloride to stop his heart.
If a patient needed a big dose of muscle relaxant, it can mean more time on a ventilator as those drugs wear off.
Elan Pharmaceuticals ' sale of the muscle relaxant Skelaxin to King Pharmaceuticals could be endangered by an investigation into the drug by the U.S. Federal Trade Commission.
The sugammadex molecule resembles a hungry octopus, with eight chemical arms that can grab the muscle relaxant already sold by Organon and put it into a mawlike hole.
He told the BBC News website the relationship between hCG and production of the muscle relaxant was still not completely clear, and the causes of prematurity were complex.
The patent protecting the active chemical in the drug has already expired, but a second patent, on using that chemical as a muscle relaxant, is valid until December 2021.
Mr Barham, 48, said doctors were "keeping him asleep for now" but had earlier reduced the muscle relaxant they were treating him with and "he coughed and wriggled his fingers".
To accomplish this unique approach, Organon chemist Anton Bom came up with a molecule that resembles a hungry octopus, with eight chemical "arms" that can grab the muscle relaxant and trap it in a maw-like hole.
