Anxiolytic effects opiates

Just one year after Hoffmann s synthesis, the Bayer company started the production of heroin (the word is related to heroic, on account of its anxiolytic effect). The drug, which is also known as diamorphine, was used for the treatment of severe coughs, labour pains and to premedicate narcoses (Fig. 5.58). It was the first semi-synthetic opiate on the drug market, and found use for severely wounded soldiers during the First World War, and for certain neurotic Alnesses. As a consequence of the associated potential for addiction, which had been completely underestimated in the beginning, the drug had disappeared by 1931 again from almost aU pharmacopoeias. 

The few controlled studies of pharmacotherapy for AN have largely been disappointing. No class of medication has consistently proved effective in the treatment of AN consequently, pharmacotherapy plays a relatively minor role in the routine management of the disorder. Nevertheless, a review of the medications tested for the treatment of AN is informative. Medications used in the treatment of AN include appetite stimulants, antidepressants, antipsychotics, anxiolytics, trace mineral supplementation, prokinetics, and opiate antagonists.

Sigma receptor ligands bind to metabotropic GPCRs as well as ionotropic cr-Rs (Chapter 3). Endogenous ligands for cr-Rs include some opiates. Sigma-R activation can have antitussive, anxiolytic and ulceroprotective effects. Hypericin from Hypericum perforatum (St John s wort) is... 

Benzodiazepine abuse is different from other substance abuse disorders (opiates, amphetamines, and nicotine) because benzodiazepines cause much less euphoria and do not activate the classic reward systems that are activated with other substances (mainly the mesolimbic and mesocortical dopaminergic projections). In fact, most people do not find the subjective effects of benzodiazepines pleasant beyond their therapeutic anxiolytic or sleep-inducing effects. Therefore, abuse of benzodiazepines is usually secondary to other substance-abuse disorders, with the benzodiazepine being taken for relief from symptoms induced by the use of another drug. As potential drugs of abuse, short-acting benzodiazepines seem to be preferred among addicts because of the rapidity of their onset of action (aiprazoiam, fiunitrazepam, and iorazepam).
