LITTLE ROCK, Ark. (AP) — The three drugs Arkansas plans to use to execute eight inmates meet federal potency and purity requirements, according to a laboratory hired by the Arkansas Department of Correction.Attorneys for the Arkansas attorney general’s office submitted an affidavit Wednesday showing the Correction Department had hired a Food and Drug Administration-certified pharmaceutical testing laboratory to make sure the drugs meet those federal standards. The name and address of the company were redacted, but the test results were included with the affidavit submitted in an ongoing lawsuit by several death row inmates.The Arkansas Supreme Court has put those executions on hold pending the resolution of the inmates’ challenge.“The test results confirm that the contents of the vials match FDA-approved labelling and demonstrate that all three drugs meet applicable potency requirements,” Department of Correction Deputy Director Rory Griffin wrote in the affidavit.The state obtained the midazolam, vecuronium bromide and potassium chloride last year. Under the state’s new execution secrecy law, the Department of Correction has withheld the manufacturer and distributor of those drugs as well as other information.Questions were raised about the sedative midazolam after inmates gasped and groaned during longer-than-expected executions in Oklahoma, Ohio and Arizona.Attorney Jeff Rosenzweig, who represents the inmates, declined to comment on the affidavit Wednesday.The inmates say the state’s secrecy law is unconstitutional and they want information on the drugs’ makers and suppliers to determine whether they could lead to cruel and unusual punishment.
