What was used in botched Oklahoma execution

The drugs given to Oklahoma inmate Clayton D. Lockett were potent medications with potentially serious side effects. In executions, they are typically injected in order, at high doses.

Midazolam is a short-acting sedative sold under the brand name Versed, sometimes used to calm patients before medical procedures or before surgery involving general anesthesia. Side effects can include serious breathing problems and cardiac arrest.

Vecuronium bromide is a muscle relaxant used during some surgeries. It also can cause breathing difficulties.


Potassium chloride is used to treat potassium deficiency but is used in executions to stop the heart.
