is soma a barbiturates

Barbiturates are a class of drugs derived from barbituric acid, which act as depressants in the central nervous system. These are CNS depressants, which are also used as sedatives and hypnosis drugs. The drug is used to treat insomnia, seizures, and headaches.
Barbiturates are sedatives that have a calming and relaxing effect compared to alcohol’s effect. They are used to treat certain conditions such as seizuresanxiety and as an anesthetic during surgery. They can also be used to alleviate the negative withdrawal effects of illegal drugs when used similarly to benzodiazepines such as diazepam and clonazepam.

Soma is a muscle relaxer drug that blocks pain sensation between the nerves and the brain. It is used as a short-term treatment for muscle pain. It is practiced unitedly with rest and physical therapy to heal skeletal muscle conditions like soma for backpain and injury
The drug should only be practiced for the short course (up to two or three weeks) because there is no proof of its effectiveness in long-term utilization and most skeletal muscle injuries are generally of a short span.

Are Soma and barbiturate the same thing?

Soma works as a muscle relaxer that blocks pain sensation between the nerves and brain. It is prescribed to offer relief from pain.

Barbiturates are synthetic drugs. The chief mechanism of action of barbiturates is inhibition of the central nervous system. It is prescribed to cure insomnia (sleeping disorder), seizures, and headaches. Barbiturates are also used in the treatment of epilepsy, where short-acting molecules are used for anesthesia. Long-acting barbiturates such as phenobarbitalluminalmephobarbital, and Mebaral are classified as class I drugs and are used as anticonvulsants.

What are the differences between Soma and barbiturate?

Generic name for soma is carisoprodol. Barbiturate is sold under many brand names like amobarbital, secobarbital, butabarbital, pentobarbital, etc.

Soma is used to treating muscle pain, whereas barbiturate is used to treat extreme cases of insomnia, seizures that are unresponsive to other, less toxic agents, etc.

The difference between their Half-life, Dosages and Side effects

Soma takes 30 minutes to kick in. on the other hand, barbiturates have various onsets of action. Oral varies from 20 to 60 minutes, and intravenous can vary from almost immediate to 5 minutes.
The half-life of Soma is around 2 hours; it may vary from 1-3 hours in some people. The half-life of barbiturate varies from 4-38 hours.
Soma comes in tablet form. The dosage of barbiturates depends upon the drug and its uses.

Side effects-

How long does Soma and Barbiturate stay in your system?

Soma would take an average of 11 hours to eliminate from your body after consumption. Soma leaves back metabolites as well. The meprobamate metabolite can take around four days to be excluded from the body, even after the original drug has been fully eliminated.

Barbiturate stays up to 72 hours after consumption.
The effect of interacting barbiturates such as butobarbital sodium lasts between 6 and 12 hours and is used to treat insomnia. However, the effects of longer-acting barbiturates such as barbital and phenobarbital can last up to 24 hours, making them useful with other active ingredients to prevent seizures in epilepsy. The effects of these medications can last up to 24 hours, and they can be used in conjunction with other medications in the treatment of epilepsy as they have a long-lasting depressive effect that helps prevent convulsions.


Many people stopped taking barbiturates when word spread of their high potential for abuse, and less addictive drugs replaced them in the benzodiazepine’s family.
Frequent barbiturate users can experience severe withdrawal symptoms up to 8 to 15 hours after stopping the drug. The more a person takes the drug, the greater the difference between the doses that can cause the desired effect and the fatal overdose.
Soma is the most preferred drug for muscle relaxants. The quality and effectiveness of the drug make it a priority for doctors to prescribe them for patients.
