Pentobarbital for sale near me
Pentobarbital, also known as pentobarbitone, is a short-acting barbiturate primarily used as a sedative, preanesthetic, and emergency anticonvulsant. While it was once employed for short-term insomnia treatment, benzodiazepines have largely supplanted it for this purpose. In high doses, pentobarbital can induce respiratory arrest, leading to its use in veterinary euthanasia and, in certain jurisdictions, for human euthanasia and capital punishment.
Uses
Medical
Pentobarbital is utilized for sedation, short-term hypnosis, preanesthesia, and emergency seizure control. It can also reduce intracranial pressure in conditions like Reye’s syndrome and traumatic brain injury. Additionally, it’s used as a veterinary anesthetic.
Euthanasia and Assisted Suicide
In high doses, pentobarbital causes death by respiratory arrest. It’s used for euthanasia in both humans and animals. In the Netherlands, it’s part of the standard protocol for physician-assisted suicide, administered in liquid form preceded by an antiemetic. In some U.S. states, it’s used orally for physician-assisted death.
Execution
Pentobarbital has been used as a substitute for sodium thiopental in U.S. lethal injections. Due to production halts and importation challenges of sodium thiopental, some states have adopted pentobarbital, either alone or in combination with other drugs, for executions. Its use in this context has been controversial, leading some manufacturers to restrict its distribution to prevent use in capital punishment.
Pharmacology
Pharmacodynamics
Pentobarbital binds to the GABA-A receptor, enhancing the duration of chloride channel opening and potentiating GABA’s inhibitory effects on the central nervous system. At high doses, it can open these channels independently of GABA, leading to pronounced CNS depression.
Pharmacokinetics
Pentobarbital is rapidly absorbed, with intravenous administration leading to immediate onset of action. It undergoes first-pass metabolism in the liver, with an elimination half-life ranging from 15 to 50 hours. Metabolites are primarily excreted via the urine.
Drug Interactions
Concurrent use of pentobarbital with other central nervous system depressants, such as ethanol, benzodiazepines, opioids, and antihistamines, can lead to additive effects, increasing the risk of profound sedation or respiratory depression.
Chemistry
Pentobarbital is synthesized through alkylation of α-ethylmalonic ester with 2-bromopentane. It is commonly formulated as the sodium salt, pentobarbital sodium, which is more soluble in water compared to its free acid form.
Society and Culture
Pentobarbital is known by the trade name Nembutal. Historically, it was available in capsule form and was subject to abuse, colloquially referred to as “yellow jackets” due to the color of the capsules. Manufacturers have since discontinued the capsule form, and its use has declined with the advent of benzodiazepines.
