Pentobarbital is a powerful barbiturate drug sold under the trade name Nembutal. This drug can be used as an anesthesia, prior to surgery or procedures, and as a sedative. Nembutal is used to treat symptoms associated with certain brain injuries as well. There are certain places where Nembutal is used as an assisted suicide drug. Nembutal is also highly addictive and potentially deadly when it’s misused. At one point in the 1950s, prescribing barbiturates like Nembutal was commonplace. These drugs were prescribed for common conditions like anxiety or sleeping problems. However, it became clear that drugs like Nembutal were habit-forming and potentially deadly. While Nembutal is rarely used in human medicine, it is still used in veterinary medicine. Despite its limited availability, people are still able to illegally obtain Nembutal.
Nembutal (Pentobarbital) Prescription Facts
Countries around the world have made it difficult to obtain Nembutal, and it’s primarily only available in an injectable form in hospitals. In hospital settings, it can be used as an anesthetic and sedative. Despite the difficulty, it is still possible to illegally obtain Nembutal on the black market or through medical diversions. There are some reports of people obtaining Nembutal in powder form from China via the black market, as an example. In the U.S. pentobarbital is a Schedule II controlled substance. This means possessing it illegally is punishable by jail time. Laws for the use of pentobarbital are similar around the world.
Since the 1970s, the number of prescriptions and instances of abuse have gone down significantly. Doctors have moved away almost entirely from prescribing these drugs and, instead, prescribe benzodiazepines which have similar effects with fewer risks. Despite the trend away from prescribing these drugs, barbiturate abuse has gone up somewhat in recent years -especially among teens. Some of the most commonly abused barbiturates include pentobarbital, amobarbital and secobarbital.

All barbiturates, including Nembutal, are sedative-hypnotics. This drug class affects GABA receptors in the brain, inhibiting neural activity. When someone uses Nembutal, they may feel relaxed, euphoric or sedated. Common side effects of Nembutal include dizziness, balance and coordination impairment, nightmares or sleep problems, and cognition and memory problems. A person who has used Nembutal in a relatively low dose may seem like they’re intoxicated because of the slowdown effect on the brain and central nervous system. Loss of inhibitions, slurred speech and confusion may occur as well. When taken in higher doses, Nembutal can cause respiratory depression, coma and death.

One of the reasons that barbiturates are so dangerous is that the difference between a sedating dose and a deadly dose can be incredibly small. Nembutal also causes a physical dependence to form. When someone is dependent upon the drug and suddenly stops using Nembutal, they can experience life-threatening withdrawal symptoms. These can include hallucinations, raised body temperature, delirium and seizures.

The half-life of a drug is how long it takes half of a dose to be eliminated from the system. It’s important to know what the half-life of a drug is for a few different reasons. First, knowing how long it takes the drug to leave the body can indicate when withdrawal symptoms begin in a person who is dependent. Because of the severity of barbiturate withdrawal, this information is vital to know. Barbiturates can also lead to fatal overdoses when they’re combined with other central nervous system depressants like alcohol. Knowing the half-life of Nembutal can help prevent an accidental drug combination that could lead to a deadly overdose.

The half-life of Nembutal is anywhere from 15 to 50 hours. Nembutal starts working very quickly when it’s injected. When it is intravenously injected, Nembutal will take effect anywhere from three to five minutes later. When the drug is intramuscularly injected, Nembutal will usually start working within 10 to 15 minutes. The duration of Nembutal effects is around three to four hours.

Nembutal’s half-life has a very wide range. Different factors can affect how long a drug like Nembutal stays in the system. First, the route of administration and the dosage are relevant. The age of the individual is also relevant. Older people tend to eliminate drugs more slowly than younger, healthier people. Body weight and body fat can also influence how long Nembutal stays in the system, as can the presence of any other substances used in combination with Nembutal.
Pentobarbital is considered to be a short-acting barbiturate, compared to other drugs in this class. However, since the drug’s half-life can range anywhere from 15 to 50 hours, there is a lot of variation. For the most part, Nembutal may show up in the urine for anywhere from 24 to 72 hours after it is used. Pentobarbital wouldn’t likely show up on a blood test for very long, although it could be found in hair follicles for a few weeks after it’s used. Barbiturates are often tested for in standard drug screening panels, unlike some other prescription drugs.
