A pharmacy in the US state of Oklahoma has agreed not to supply a powerful sedative to a neighbouring state for use in an execution, a court has heard.
Missouri officials had reportedly planned to buy pentobarbital from the Apothecary Shoppe in Tulsa to execute convicted murderer Michael Taylor. The pharmacy's move came after Taylor's lawyer sued to block the sale.
US states are facing a shortage of execution drugs as a growing number of firms have refused to sell them.
Despite the development, revealed in court on Monday, Missouri Governor Jay Nixon has said prison officials are prepared to go forward with the execution, currently scheduled for 26 February.
In Taylor's case, his lawyers said the state turned to the Apothecary Shoppe, a compounding pharmacist that makes bespoke drugs for individual clients, after the sole US licensed manufacturer of pentobarbital, Akorn Inc, refused to sell it for use in lethal injections.
