Finally, note that the benzodiazepine core is a privileged scaffold, which has been used to derive drugs with diverse activity that is not limited to the GABA A modulatory action of the classical benzodiazepines, [60] such as devazepide and tifluadom, however these have not been included in the list below. 2,3-benzodiazepines such as tofisopam ...
[15] [16] The College of Physicians and Surgeons of British Columbia recommends discontinuing the usage of benzodiazepines in those on opioids and those who have used them long term. [29] Benzodiazepines can have serious adverse health outcomes, and these findings support clinical and regulatory efforts to reduce usage, especially in ...

Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
Despite this, opioids and benzodiazepines are concurrently dispensed in many settings. [155] [156] As with an overdose of opioid alone, the combination of an opioid and another depressant may precipitate respiratory depression often leading to death. [157]
Mixing opioids with another depressant, such as benzodiazepines or alcohol, increases the chance of an overdose and respiratory depression. Opioid overdose causes a decreased level of consciousness, pinpoint pupils , and respiratory depression.
Glutamate is the principal excitatory neurotransmitter in the mammalian CNS. Taken together, the findings that barbiturates potentiate inhibitory GABA A receptors and inhibit excitatory AMPA receptors can explain the superior CNS-depressant effects of these agents to alternative GABA potentiating agents such as benzodiazepines and quinazolinones.
The Convention on Psychotropic Substances of 1971 is a United Nations treaty designed to control psychoactive drugs such as amphetamine-type stimulants, barbiturates, benzodiazepines, and psychedelics signed in Vienna, Austria on 21 February 1971.
