Brief overview
Benzodiazepines are centrally acting drugs that have an anxiolytic, calming, muscle relaxant, sleep-inducing and antispasmodic effect. They are used medically in particular for the short-term treatment of anxiety, sleep and restlessness.
Known active ingredients:
- Diazepam
- Lorazepam
- Clonazepam
- Oxazepam
- Alprazolam
Consumer Application
Medical:
- oral (tablets / drops)
- intravenously, e.g. in an emergency (seizures, status epilepticus)
- as a short-term sleep aid
Non-Medical Use:
- Tablets crushed & snorted
- taken orally
- Less often injected
Mechanism of action
Benzodiazepines enhance the effect of the inhibitory neurotransmitter GABA in the brain by increasing the ability of GABA to bind to the GABA-A receptors. As a result:
- Neuronal excitability decreases
- Reduce anxiety & tension
- the sedative effect increases
Results
| Results | Description |
|---|---|
| Anxiolytic | Attenuation of acute anxiety reactions |
| Calming | Reduction of inner restlessness & overexcitement |
| Muscle relaxant | Muscle tone reduction |
| Sleep-inducing | Reduction of the time it takes to fall asleep |
| Anticonvulsant | Treatment of seizures |
Risks & Side Effects
| Risk | Details |
|---|---|
| Fatigue, slow reaction | relevant in road traffic |
| Memory and concentration disorders | especially for continuous use |
| Risk | especially among older people |
| paradoxical reactions | rare: restlessness, aggressiveness, agitation |
| Respiratory depression | especially in combination with alcohol / opiates |
| Tolerance development | Effect decreases → dose increase |
| Dependency | Primarily when taken for a long time |
Important: Benzodiazepines should never be discontinued abruptly. → tapering off under medical supervision.
Detectability in the drug test
| Test type | Detection time (variable by substance) |
|---|---|
| Urine | 1-7 days, up to weeks for long-term use |
| Blood | a few hours to 24 h |
| Saliva | 1-48 hours |
| Hair | 60-90 days or longer depending on the active ingredient |
Long-acting variants (e.g. diazepam) can be detected for much longer than short-acting variants (e.g. alprazolam).
Risk of abuse
Benzodiazepines can lead to:
- psychological dependence
- Tolerance development
- Withdrawal symptoms (anxiety, sleep disorders, muscle tremors, rebound insomnia)
.
In particular, combinations with:
- Alcohol
- Opioids
- other sedative substances
significantly increase the risk of respiratory depression.
In summary
Benzodiazepines are effective, medically established substances, but they carry a relevant risk of dependence and side effects if used for a long time or improperly. The therapy is controlled, limited in time and according to clear indication guidelines.
