Definitions

  • the present invention relates to a novel use of (S)-4-amino-N-(4,4-dimethylcyclohexyl)glutamic acid (CR 2249-neboglamine) (CAS Registry Number 163000-63-3), the racemic mixture thereof or a pharmaceutically acceptable salt thereof, for use in the treatment of toxicodependency induced by drugs such as Central Nervous System (CNS) sedatives such as opiates, benzodiazepines, barbiturates, alcohol, stimulants such as amphetamines and cocaine, and hallucinogens such as LSD, mescalin, cannabis (marijuana) or fencyclidine.
  • CNS Central Nervous System
  • psychological dependency means an irresistible impulse (compulsion) to continue self-administering the drug in order to find pleasure.
  • the psychological dependency is the most important factor in their compulsive use.
  • the term “physical dependency” means a state of habituation to the drug accompanied by tolerance and that is manifested by abstinence syndromes.
  • Tolerance is the need to increase the dose of the drug in order to obtain the same effects as were initially obtained with lower doses; the abstinence syndrome is characterized by painful physical sensations that are manifested when the taking of the drug is stopped.
  • CNS sedatives such as opiates, benzodiazepines, barbiturates and alcohol, which also all induce physical dependency and tolerance
  • CNS stimulants for instance amphetamine and cocaine which induce physical dependency to a minor extent, if at all
  • hallucinogens such as LSD, mescalin, cannabis (marijuana) and fencyclidine.
  • neboglamine (CR 2249) has been shown to have significant modulatory properties on the glycine site (strychnine-insensitive) coupled to the NMDA receptor complex [Lanza et al., Neuropharmacology 36, 1057-64 (1997)], and also advantageous properties of promoting memory and learning in various animal models [Garofalo et al. J. Pharm. Pharmacol. 48, 1290-97 (1996)].
  • the facilitatory activity exerted by neboglamine on the NMDA receptor complex should be of therapeutic use in conditions of glutamatergic hypo functionality.
  • NMDA receptor complex may be involved in a variety of functional responses to cocaine, for instance locomotor activity, dependency (continued reinforcement of self-administration), tolerance and toxicity (Rockhold R. W., Progress in Drug Research 50: 155-92, 1998).
  • glycine is capable of inhibiting the locomotor hyperactivity, tolerance and dependency induced by morphine in mice (K. W. Shin et al., Arch. Pharm. Res. 26: 1074-1078, 2003).
  • neboglamine was evaluated in animal experimental models that may be considered as predictive for the evaluation of toxicodependency induced by various drugs such as cocaine, morphine and benzodiazepines, which are widely representative of the syndromes caused by toxicodependency.
  • the motor activity was measured with a video camera and recorded using the Videotrack 512 system as described by Garofalo (J. Pharm. Pharmacol. 48: 1290-1297, 1996).
  • Physiological saline, neboglamine (30 mg/kg) or glycine (300 mg/kg) were administered via the i.p. route 30 minutes before physiological saline, morphine (10 mg/kg s.c.) or cocaine (20 mg/kg s.c.).
  • the locomotor activity was recorded for 15 minutes and the total distance covered (in cm) by the animal was recorded by the computer connected to the video camera. The results thus obtained are collated in Table 1.
  • Neboglamine (30 mg/kg) or physiological saline were administered via the i.p. route 30 minutes before morphine (10 mg/kg s.c.) for 6 days. On the seventh day, the test was performed, as described in the preceding experiment, in comparison with a group of animals treated with the same dose of morphine given acutely only on the 7th day (final day of the, experiment). The results thus obtained are collated in Table 2.
  • Chronic treatment with morphine induces an increase in the motor activity of the rat, compared with the acute effect of the drug, by about 50% (128.6% as opposed to 80.3%).
  • Chronic pre-treatment with neboglamine (30 mg/kg i.p for 7 days) succeeds in almost completely antagonizing (70.8%) the development of the inverse tolerance induced by the chronic treatment with morphine.
  • the rat placed in one of the closed quadrants, had free access to all 4 of the quadrants (2 open and 2 closed) for a period of 5 minutes.
  • a compound with anxiolytic activity produces a percentage increase in the time spent in the free quadrants.
  • Physiological saline 40 100.0 Acute diazepam (D) 5 105 262.5 Chronic diazepam (D-C) 5 ⁇ 2 ( ⁇ 7 days) + 5 (D) 58 145.0 Acute neboglamine (N) 30 51 127.0 Physiological (D-W) — 15 37.5 Neboglamine+ (D-C) 30 ⁇ 2 ( ⁇ 7 days) + 30 + 5 (D) 77 192.5 Neboglamine (D-W) — 44 110.0 Note: Physiological (D-W) is the group treated with diazepam for 7 days and retested 40 hours later with physiological saline. Neboglamine (D-W) is the group treated with diazepam and neboglamine for 7 days and retested 40 hours later with physiological saline
  • Neboglamine displays non-significant anxiolytic activity (127% compared with the controls). However, its co-administration with diazepam does not reduce tolerance (192.5% effect compared with the control). In addition, the co-administration of neboglamine was shown to inhibit the abstinence crisis induced by stoppage of the chronic treatment with diazepam [110% of effect for the group N-(D-W) as opposed to 37.5% of effect for the group (D-W)].
  • compositions comprising as active principle neboglamine or the racemic mixture thereof, in native form or pharmaceutically acceptable salts thereof.
  • compositions for using the compounds according to the invention may be prepared using conventional techniques.
  • the formulations include those suitable for oral use, for instance capsules, tablets, suspensions, emulsions, solutions; sterile solutions for parenteral use (including subcutaneous, intramuscular and intravenous administration), or preparations for topical or rectal use or other forms suitable for obtaining the desired therapeutic effect, for example solid formulations for oral use with delayed action, which allow a slow release of the active principle over time.
  • Substances commonly used in the pharmaceutical field as excipients, binders, disintegrants and substances capable of stimulating transdermal absorption may be used together with the active principle in the pharmaceutical formulation.
  • Neboglamine compounds such as the racemic mixture thereof, may thus be used in native form or as pharmaceutically acceptable salts.
  • neboglamine it is preferably the sodium or potassium salt or the hydrochloride.
  • the effective therapeutic amount of neboglamine to be used for the treatment of drug-induced toxicodependency should be between 10 and 600 mg and preferably from 30 to 300 mg per day of active principle, depending on the specific conditions of the treated patient, and the individual response to the treatment, the age and the weight of the patient.
