Until 2010, most states used a 3-drug combination for lethal injections: an anesthetic (either pentobarbital or, formerly, sodium thiopental), pancuronium bromide (a paralytic agent, also called Pavulon), and potassium chloride (stops the heart and causes death). Due to drug shortages, states have adopted new lethal injection methods, including:
ONE DRUG: Eight states have used a single-drug method for executions--a lethal dose of an anesthetic (Arizona, Georgia, Idaho, Missouri, Ohio, South Dakota, Texas, and Washington). Five other states have announced use of one-drug lethal injection protocols, but have not carried out such an execution (Arkansas, Kentucky, Louisiana, North Carolina, and Tennessee).
PENTOBARBITAL: Fourteen states have used pentobarbital in executions: Alabama, Arizona, Delaware, Florida, Georgia, Idaho, Mississippi, Missouri, Ohio, Oklahoma, South Carolina, South Dakota, Texas, and Virginia. Five additional states plan to use pentobarbital: Kentucky, Louisiana, Montana, North Carolina, and Tennessee. Colorado includes pentobarbital as a backup drug in its lethal injection procedure.
PROPOFOL: One state had planned to use propofol (Diprivan), in a single-drug protocol, but has since revised its lethal injection procedure: Missouri
MIDAZOLAM: One state has used midazolam as the first drug in a three-drug protocol: Florida. One state has used midazolam in a two-drug protocol: Ohio. One state has announced plans to use midazolam in a two-drug protocol: Louisiana.
COMPOUNDING PHARMACIES: Six states have either used or intend to use compounding pharmacies to obtain their drugs for lethal injection. South Dakota carried out 2 executions in October 2012, obtaining drugs from compounders. Georgia obtained drugs from an unnamed compounding pharmacy for the planned execution of Warren Hill in 2013, but the execution was stayed. Pennsylvania obtained drugs from a compounder, but has not used them. Colorado sent out inquiries to compounding pharmacies for lethal injection drugs, but all executions are on hold. Missouri used pentobarbital from a compounding pharmacy in the November 20, 2013 execution of Joseph Franklin. Texas and Ohio announced plans to obtain drugs from compounding pharmacies in October, 2013. Documents release in January, 2014, show that Louisiana had contacted a compounding pharmacy regarding execution drugs, but it is unclear whether the drugs were obtained there.
In federal executions, the method is determined by the state in which the sentencing took place. All 3 of the federal executions in the modern era have been by lethal injection carried out in a federal facility in Indiana. Apparently, a 3-drug combination was used, though prison officials did not reveal the exact ingredients. (See Washington Post, Dec. 5, 2000). The U.S. Military has not carried out any executions since reinstatement. It plans to use lethal injection.
