Secobarbital sodium is a barbiturate derivative drug. Secobarbital may produce psychological addiction and produces physical dependence if used for an extended period of time. Secobarbital overdose was the most common method of implementing physician assisted suicide in Oregon for many years. Subsequently, pentobarbital has dominated in Oregon PAD. Ranbaxy Laboratories Limited previously experienced various issues in their attempts to produce 100 mg secobarbital capsules. Currently, Marathon Pharmaceuticals is the sole marketer of the drug in the United States, although the drug remains manufactured by Ohm Laboratories. Secobarbital was widely misused in the 1960s and 1970s, and accidental overdose was associated with the drug. It was linked with the death of Judy Garland where the postmortem found that her blood contained the equivalent of ten 1.5-grain (97 mg) Seconal capsules.
