What Do Barbiturates Do?
The core side effects of barbiturates, sedative-hypnotics include relaxation and drowsiness. Barbiturates effects are also anticonvulsant, meaning that they can halt or prevent seizures and convulsions.
Barbiturates impact the brain by enhancing the activity of GABA (gamma-aminobutyric acid), a neurotransmitter or chemical messenger. This increase in GABA levels in the brain leads to a reduction in the activity of brain cells, slowing down neural processes.
Common applications for barbiturates include their use in anesthesia, the treatment of epilepsy, both epileptic and non-epileptic seizures, as well as the management of insomnia and other related conditions.
Common Effects Of Barbiturates
Barbiturates drugs side effects occur as the drug depresses the CNS (central nervous system). Barbiturate side effects can occur immediately and over the long-term.
Short-Term
These are the most common short-term effects of barbiturates:
- Sedation and relaxation: Barbiturates induce a calming and sedative effect, leading to feelings of relaxation and reduced anxiety.
- Drowsiness: Many barbiturates can cause drowsiness, making them effective for addressing sleep disorders like insomnia.
- Anticonvulsant properties: Barbiturates can rapidly halt or prevent seizures and convulsions, making them valuable for treating epilepsy and related conditions.
- Euphoria: In higher doses, some people may experience feelings of euphoria, which can contribute to their misuse and potential for addiction.
- Impaired cognitive and motor function: Barbiturates can impair cognitive abilities, including thinking, decision-making, and concentration. Motor skills and coordination may also be affected.
- Respiratory depression: High doses or misuse of barbiturates can lead to slow and shallow breathing, which can be life-threatening.
- Physical dependence: Even in the short term, regular use of barbiturates can trigger the development of physical dependence.
Long-Term
Long term effects of barbiturates include:
- Tolerance: Long-term use often results in tolerance, where individuals require increasingly higher doses to achieve the same effects.
- Psychological dependence: Regular use can lead to psychological dependence.
- Withdrawal symptoms: Stopping barbiturate use can cause severe withdrawal, including anxiety, tremors, seizures, and hallucinations.
- Cognitive impairment: Long-term effects may include cognitive deficits.
- Liver and kidney damage: Extended use can damage these organs.
- Risk of overdose: Long-term users may take higher doses, increasing overdose risk.
- Interactions with other medications: Barbiturates can interact with various drugs and reduce effectiveness or cause adverse reactions.
