In the week since the execution in Georgia of Troy Davis, who had convinced hundreds of thousands of people that he was innocent but failed to win his court appeals, America’s death penalty has been back in the spotlight.

Those discussions reflect what could be some change in public opinion toward the death penalty after Troy Davis. The sentiment may be shared by companies, too, as the Guardian reports that a Danish drug firm is demanding the state of Florida not use its anesthetic in a Thursday execution.

Staffan Schuberg, president of Lundbeck, which manufactures pentobarbital under the trademark named Nembutal, has written to Florida Gov. Rick Scott (R) to urge the drug not be used.

The use of Nembutal in an execution “contradicts everything Lundbeck is in business to do—provide therapies that improve people's lives,” Schuberg wrote.

Experts have said that the untested drug could cause extreme suffering for prisoners as they die.

While Lundbeck now limits sales of Nembutal to prisons or corrections departments in the U.S., several states have already stockpiled it.

The drug is being increasingly used since a U.S. manufacturer suspended supply of the anesthetic sodium thiopental, also saying it didn’t want that drug used in executions.

Unless there is a last-minute stay, Nembutal will be administered at 3 p.m. Thursday to Manuel Valle, who was convicted of the 1989 murder of a police officer.

It will be Florida's first use of the drug as part of a lethal injection.
