Definitions

  • This invention relates to the use of 2,3-benzod ⁇ azep ⁇ ne derivatives for the preparation of pharmaceutical compositions " useful for the treatment or prevention of diseases connected with disturbances of the opioid system Background of the invention
  • Hedonia the overstated demand of pleasure
  • ahedonia inability to feel pleasure
  • these symptoms are mentioned in the Diagnostic and Statistical Manual of Mental Disorders, IV ed (American Psychiatric Association, Washington D C , USA, 1994) among diagnostic criteria for schizophrenia and depression
  • the increased desire of pleasure is considered to play an important role by initiating the progress of disease state [Drug addiction and alcoholism and opioid signals, Koob, G F Ann N Y Acad Sci 654 1171-191 (1992)]
  • the state of pleasure is primarily the consequence of specific actions of the endogenous opioid peptides [(Ber ⁇ dge, K C Neurosci Biobehav Rev 20 1-25 (1996)]
  • the opioid peptide is released and acts only in areas of the brain performed to evoke the state of pleasure, on the other hand the appropriate receptor of the opioid peptides
  • the present invention is based on the recognition that the effect of 2 " 3-benzod ⁇ azep ⁇ ne derivatives on the behaviour of experimental animals is inhibited in states of opioid tolerance induced by morphine This means that the compounds are acting via the opioid signal transduction system Consequently, the 2,3-benzod ⁇ azep ⁇ nes may be employed in the therapy or prevention of disease states in which the endogenous opioid system is playing a role Disturbances of the hedonic state (increased or depressed ability of feeling pleasure) are the most characteristic examples of these symptoms of diseases
  • the experiments were carried out in Charles River Wistar rats The animals were treated subcutaneously with saline or morphine for 4 consecutive days Treatments were carried out twice a day between 8 and 9 o'clock a m and between 17 and 18 o'clock p m
  • the group treated with morphine received on the first day two times 5 mg/kg, on the second day two times 10 mg/kg, on the third day two times 15 mg/kg and on the fourth day two times 20 mg/kg of morphine
  • This treatment schedule decreases the analgesic potency of morphine to about one fifth 18 hours after the last treatment
  • the test compounds, that is the 2,3- benzodiazepine derivatives were administered on the fifth day On the fifth day of the experiment, 15-20 hours after the last treatment, open field tests were carried out as specified in the literature [(Van Ree, J M , G Wolternik "Motility and grooming as measures of anxiolysis with homophtalazines", Eur J Pharmacpl 72 107-

  • Figure 1 shows the effect of tofisopam, nerisopam and girisopam on the motility and grooming behaviour of rats in open field test after treatment with saline or morpholine
  • Tables 1-3 are presented as percentages of the control values
  • the vertical bars indicate the standard errors of the mean, * P 0 05, ** P 0 01 (analysis of variance followed by Duncan test)
  • the 2,3-benzod ⁇ azep ⁇ nes induce their psychopharmacological effects (anxiolysis) due to an action on the endogenous opioid system evoking good feeling, pleasure
  • This effect envisages that the 2,3-benzod ⁇ azep ⁇ ne derivatives may be employed to treat or prevent hedonic disturbances These disturbances are present in cases of schizophrenia, depression, alcoholism or drug dependence In cases of schizophrenics with anhedonia the 2,3- benzodiazepine derivatives increasing the feeling of pleasure decrease the desire for drug or alcohol.
  • depression induced by stress or loss of weight of animals induced by stress may be counteracted by 2,3-benzodiazepines.
  • compositions of the present invention useful for the treatment or prevention of diseases connected with the opioid system can be prepared by methods known per se by admixing the active ingredient with suitable inert solid or liquid carriers and bringing the mixture to galenic form.
  • compositions of the present invention can be presented preferably in the form of orally administerable preparations (such as tablets, pills, coated pills, soft or hard gelatin capsules, solutions or suspensions etc.), or as compositions for parenteral (e.g. injection solutions), rectal (e.g. suppositories) or nasal (e.g. aerosols) administration.
  • the pharmaceutical compositions may release the active ingredient at once, in which case the duration of the effect depends only on the duration of effect of the applied ingredients When applying special pharmaceutical compositions, however, the release of the active ingredient may be prolonged, and in this case the duration of the therapeutic effect is influenced by the form of the pharmaceutical composition as well (sustained-release or controlled-release preparations)
  • compositions can be prepared by methods generally applied in the pharmaceutical industry
  • inorganic salts secondary calcium phosphate, calcium sulfate, calcium carbonate, etc
  • gelatin polyvinyl pyrrolidone, different cellulose ethers (hydroxypropyl cellulose, hydroxypropyl methyl cellulose, methyl cellulose, ethyl cellulose, etc ), hydrolyzed starches, various vegetal gums (gum arable, guar gum) may be applied in solutions formed with water, C ⁇ - aliphatic alcohols or the mixtures thereof
