Secobarbital Sodium (marketed by Eli Lilly and Company, and subsequently by other companies as described below, under the brand name Seconal) is a barbiturate derivative drug that was first synthesized in 1928. It possesses anaesthetic, anticonvulsant, sedative and hypnotic properties. In the United Kingdom, it was known as Quinalbarbitone.
Indications
Secobarbital is indicated for:
- Treatment of epilepsy
- Temporary treatment of insomnia
- Use as a preoperative medication to produce anaesthesia and anxiolysis in short surgical, diagnostic, or therapeutic procedures which are minimally painful.
Availability
Ranbaxy Pharmaceuticals, an India-based company now predominantly owned by the Japanese company Daiichi Sankyo, obtained the rights to market Seconal from Eli Lilly in 1998 and did so until September 18, 2008. The rights to market Seconal were then sold to Marathon Pharmaceuticals (http://marathonpharma.com), the current marketer. Seconal returned to the market in January 2009. It is available as 100 mg. capsules. Eli Lilly stopped manufacturing Seconal when Ranbaxy became the marketer of the drug. Subsequent to the time that Eli Lilly discontinued manufacture of the drug, Seconal has always been (and still is) manufactured by Ohm Laboratories in North Brunswick, New Jersey. Ohm Laboratories is a wholly-owned subsidiary of Ranbaxy (Ranbaxy acquired Ohm in 1995). The new NDC number for ordering is: 42998-679-01 Seconal is available through major wholesalers, such as Cardinal and McKesson. Walgreens, King Soopers, Kroger and other pharmacies use Cardinal as their primary wholesaler. CVS, Rite Aid, and other pharmacies primarily use McKesson.
It is available as either a free acid or a sodium salt. The free acid is a white amorphous powder that is slightly soluble in water and very soluble in ethanol. The salt is a white hygroscopic powder that is soluble in water and ethanol.

- Death as a result of withdrawl
Recreational use
Secobarbital began to be widely misused in the 1960s and 1970s, although with the advent of benzodiazepines, they have become less commonly used. Secobarbital has acquired many nicknames, the most common being reds, "red devils", or "red dillies" (it was originally packaged in red capsules). Another common nickname is "seccies". Another common nickname is "red hearts" according to the Wegman's School of Pharmacy curriculum. A less common nickname is "dolls"; this was partly responsible for the title of Jacqueline Susann's novel Valley of the Dolls, whose main characters use secobarbital and other such drugs. Another popular brand of barbiturate pill Tuinal contained a combination of secobarbital and amobarbital. Tuinal, also previously an Eli Lilly product, has not been manufactured by any company with rights to market the drug in the United States since 1998. However, as of January 30, 2009, Marathon Pharmaceuticals also began marketing Amytal (amobarbital sodium) in single-unit packaging. If a person were prescribed Seconal, and also given Amytal, the person would be taking the generic equivalent of Tuinal, provided the Seconal and Amytal were taken at the same time and in equal quantities.
Famous deaths related to use
Cause of death of Judy Garland Judy Garland was found dead in her bathroom by her husband Mickey Deans on June 22, 1969. The stated exact cause of death by coroner Gavin Thursdon was accidental overdose of barbiturates; her blood contained the equivalent of 10 Seconal 100 mg capsules.[2]
Cause of death of Alan Wilson Alan Wilson, vocalist and founding member of Canned Heat, was found dead at age 27 in 1970, from a self-induced overdose of seconal. [3]
Cause of Death of Jimi Hendrix Jimi Hendrix (musician), musician and vocalist died while at girlfriend's Monika Dannemann hotel room in London. It is uncertain how he died, but the coroner said that he had taken at least nine of his girlfriend's pills. He died September 18, 1970.

Use in physician-assisted suicide
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 1000 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.
It is a component in the veterinary drug Somulose, used for euthanasia of horses and cattle.
