Death may occur when benzodiazepines are combined with other depressants such as opiates, barbiturates, thienodiazepines, alcohol or other GABAergic substances.[1]

It is strongly discouraged to combine these substances, particularly in common to heavy doses.

Diclazepam (also known as Chlorodiazepam) is a synthetic depressant substance of the benzodiazepine chemical class that produces effects similar to diazepam, such as anxiety suppression, disinhibition, anticonvulsant, hypnotic, muscle relaxing, and amnesia when administered.[2] It was first synthesized by Leo Sternbach and his team at Hoffman-La Roche in 1960.[3] In animal models it has a potency of approximately ten times that of diazepam, of which it is a structural analog.

Diclazepam is not currently marketed as a medication, but rather sold online as a research chemical. Its potency has not been systematically tested in humans, but its closest relatives and two main metabolites are lormetazepam[4] with a potency value of x10-12 of delorazepam[5] which is roughly x10 the potency of diazepam.[6]

Users should note that the sudden discontinuation of benzodiazepines can be potentially dangerous or life-threatening for individuals using regularly for extended periods of time, sometimes resulting in seizures or death.[7] It is highly recommended to taper one's dose by gradually lowering the amount taken each day over a prolonged period of time rather than stopping use abruptly, as this can lead to crippling, potentially life-threatening withdrawal symptoms.[8]

Chemistry

Composition

Diclazepam is a drug of the benzodiazepine class. Benzodiazepine drugs contain a benzene ring fused to a diazepine ring, which is a seven-membered ring with the two nitrogen constituents located at R1 and R4. At R1, diclazepam is substituted with methyl group. Further, the benzodiazepine ring is bonded at R5 to a 2-chlorinated phenyl ring. R7 of the benzyl ring is also substituted with a chlorine group. Diclazepam also contains an oxygen group double bonded to R2 of its diazepine ring to form a ketone. This oxygen substitution at R2 is shared with other benzodiazepine drugs with the suffix -azepam.

Pharmacology

Benzodiazepines produce a variety of effects by binding to the benzodiazepine receptor site and magnifying the efficiency and effects of the neurotransmitter gamma aminobutyric acid (GABA) by acting on its receptors.[9] As this site is the most prolific inhibitory receptor set within the brain, its modulation results in the sedating (or calming effects) of diclazepam on the nervous system.

The anticonvulsant properties of benzodiazepines may be, in part or entirely, due to binding to voltage-dependent sodium channels rather than benzodiazepine receptors.[10]

Subjective effects

The effects listed below are based upon the subjective effects index and personal experiences of PsychonautWiki contributors. The listed effects should be taken with a grain of salt and will rarely (if ever) occur all at once, but heavier doses will increase the chances and are more likely to induce a full range of effects. Likewise, adverse effects become much more likely on higher doses and may include injury or death.

Preparation methods

  • Volumetric liquid dosing - If one's benzodiazepines are in powder form, they are unlikely to weigh out accurately without the most expensive of scales due to their extreme potency. To avoid this, one can dissolve the benzodiazepine volumetrically into a non-polar solution such as propylene glycol and dose it accurately based upon the methodological instructions linked within this tutorial.

Toxicity and harm potential

Diclazepam likely has a low toxicity relative to dose.[17] However, it is potentially lethal when mixed with depressants like alcohol or opioids.

It is strongly recommended that one use harm reduction practices, such as volumetric dosing, when using this substance to ensure the accurate administration of the intended dose.

Tolerance and addiction potential

Diclazepam is extremely physically and psychologically addictive.

Tolerance will develop to the sedative-hypnotic effects within 3-4 days of continuous use. After cessation, the tolerance returns to baseline in 7 - 14 days. However, in certain cases, this may take significantly longer in a manner which is proportional to the duration and intensity of one's long-term usage.

Withdrawal symptoms or rebound symptoms may occur after ceasing usage abruptly following a few weeks or longer of steady dosing, and may necessitate a gradual dose reduction. For more information on tapering from benzodiazepines in a controlled manner, please see this guide.

Benzodiazepine discontinuation is notoriously difficult; it is potentially life-threatening for individuals using regularly to discontinue use without tapering their dose over a period of weeks. There is an increased risk of hypertension, seizures, and death.[18] Drugs which lower the seizure threshold such as tramadol should be avoided during withdrawal.

Diclazepam presents cross-tolerance with all GABAergics, meaning that after its consumption all benzodiazepines will have a reduced effect.

Overdose

Benzodiazepine overdose may occur when a benzodiazepine is taken in extremely heavy quantities or concurrently with other depressants. This is particularly dangerous with other GABAergic depressants such as barbiturates and alcohol since they work in a similar fashion, but bind to distinct allosteric sites on the GABAA receptor. Thus, their effects potentiate one another. Benzodiazepines increase the frequency in which the chlorine ion pore opens on the GABAA receptor while barbiturates increase the duration in which they are open, meaning when both are consumed, the ion pore will open more frequently and stay open longer[19]. Benzodiazepine overdose is a medical emergency that may lead to a coma, permanent brain injury or death if not treated promptly and properly. Symptoms of a benzodiazepine overdose may include severe thought deceleration, slurred speech, confusion, delusions, respiratory depression, coma or death. Benzodiazepine overdoses may be treated effectively in a hospital environment, with generally favorable outcomes. Benzodiazepine overdoses are sometimes treated with flumazenil, a GABAA antagonist,[20] however care is primarily supportive in nature.

Dangerous interactions

Although many drugs are safe on their own, they can become dangerous and even life-threatening when combined with other substances. The list below contains some common potentially dangerous combinations, but may not include all of them. Certain combinations may be safe in low doses of each but still increase the potential risk of death. Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.

  • Depressants (1,4-Butanediol, 2-methyl-2-butanol, alcohol, barbiturates, GHB/GBL, methaqualone, opioids) - This combination can result in dangerous or even fatal levels of respiratory depression. These substances potentiate the muscle relaxation, sedation and amnesia caused by one another and can lead to unexpected loss of consciousness at high doses. There is also an increased risk of vomiting during unconsciousness and death from the resulting suffocation. If this occurs, users should attempt to fall asleep in the recovery position or have a friend move them into it.
  • Dissociatives - This combination can result in an increased risk of vomiting during unconsciousness and death from the resulting suffocation. If this occurs, users should attempt to fall asleep in the recovery position or have a friend move them into it.
  • Stimulants - It is dangerous to combine benzodiazepines with stimulants due to the risk of excessive intoxication. Stimulants decrease the sedative effect of benzodiazepines, which is the main factor most people consider when determining their level of intoxication. Once the stimulant wears off, the effects of benzodiazepines will be significantly increased, leading to intensified disinhibition as well as other effects. If combined, one should strictly limit themselves to only dosing a certain amount of benzodiazepines per hour. This combination can also potentially result in severe dehydration if hydration is not monitored.
