Definitions
- This invention relates to a new method of treating depression and to a new medical use of trans-5-chloro-2-methyl-2,3,3a,12b-tetrahydro-1 H-dibenz [2,3:6,7] oxepino[4,5-c]pyrrole, or a pharmaceutically acceptable acid addition salt or solvate thereof.
- Depression is a major health problem in our society and also poses a tremendous financial burden on society due to lost self-support of persons suffering from depression. Life time prevalence for major depression is estimated to be between 5 to 10 %. Various forms of depression are distinguished which are separately diagnosed according to criteria given in handbooks for psychiatry, for example in the Diagnostic and Statistical Manual of Mental Disorders 4 th edition published by the American Psychiatric Association, Washington, D.C. (1994) and in the International Classification of Diseases (ICD-10) published by the World Health Organisation (Geneva).
- ICD-10 International Classification of Diseases
- Anti- depressants are distinguished from other classes, such as anxiolytics and antipsychotics. Drugs in one category may have side-effects aggravating other psychiatric diseases not belonging to the category for which the drug treatment is given.
- Trans-5-chloro-2-methyl-2,3,3a,12b-tetrahydro-1 H-dibenz [2,3:6,7] oxepino[4,5-c]pyrrole is a drug known from US 4,145,434 for the treatment psychosis and anxiety.
- trans-5-chloro-2-methyl-2,3,3a,12b- tetrahydro-1 H-dibenz [2,3:6,7] oxepino[4,5-c]pyrrole is useful for the treatment or prophylaxis of depression. Accordingly, the present invention provides the use of a compound of formula (A):
- Formula A which is trans-5-chloro-2-methyl-2,3,3a,12b-tetrahydro-1 H-dibenz [2,3:6,7] oxepino[4,5-c]pyrrole, or a pharmaceutically acceptable acid addition salt or solvate thereof, for the manufacture of a medicament for the treatment or prophylaxis of depression.
- depression is used here for the psychiatric disorder or the symptom characterised by chronic low mood and loss of capacity to experience pleasure.
- This disease or symptom is well-recognised by a physician and can also be quantified, for example with the Hamilton Rating Scale for depression or with the Montgomery and Asberg Depression Rating Scale.
- An important characteristic of presently and frequently diagnosed depression, for example major depression and dysthymia, is that an organic disorder causing the depression cannot be detected.
- a depression due to identified pathology in the physiology or anatomy of a person is usually treated by therapeutic strategies aimed at correcting or compensating for such an organic disorder.
- Org 5222 in medicaments for treatment of mental disorders associated with a cerebrovascular disorder is known from EP 0 730 865 A1.
- Suitable acid addition salts include hydrochloric, fumaric, maleic, citric or succinic acid, these acids being mentioned only by way of illustration and without implied limitation.
- a preferred salt is maleic acid, in which case the compound is known as Org 5222.
- the present invention provides a method of treating depression with a therapeutically effective amount of trans-5-chloro-2- methyl-2,3,3a, 12b-tetrahydro-1 H-dibenz [2,3:6,7] oxepino[4,5-c]pyrrole.
- a suitable daily dose will be in the range of 0.005 to 60 mg of a compound of the present invention per person. Preferably this dose will be in the range of from 0.03 to 2 mg.
- a preferred route of administration for treatment is the sublingual route. With this route, a method of providing therapy using the pharmaceutical composition of the present invention comprises the insertion of a dosage form according to this invention in the buccal pouch or under the tongue of a person.
- the present invention further provides a pharmaceutical formulation for use in the treatment of depression comprising a compound of formula A or a pharmaceutically acceptable acid addition salt or solvate thereof, together with a pharmaceutically acceptable carrier therefor and optionally other therapeutic agents.
- the carrier must be "acceptable” in the sense of being compatible with the other ingredients of the formulation and not deleterious to the recipients thereof.
- suitable carriers are various carbohydrates, gum acacia, calcium phosphate, gelatin, talc, magnesium stearate or mineral oil.
- the invention further includes a pharmaceutical formulation as herein described, in combination with packaging material adapted for the pharmaceutical formulation, said packaging material including facilities for the use of the pharmaceutical formulation in the treatment of depression.
- packaging material including facilities for the use of the pharmaceutical formulation in the treatment of depression.
- facilities can include precautions limiting the total dose contained in the package handed over to the person for treatment in order to reduce the risk of overdosing due the misuse of the available supply.
- Suitable formulations include those adapted for oral, rectal, nasal, topical (including transdermal, buccal and sublingual), vaginal or parenteral (including subcutaneous, intramuscular, intravenous and intradermal) administration.
- the sublingual route of administration is most preferred in view of the disclosure in WO 95/23600, which is incorporated herein by reference.
- a dosage unit may contain between 0.005 mg and 15 mg of a compound of the present invention.
- the dosage unit contains 0.03 to 0.50 mg of Org 5222.
- dosage units of the pharmaceutical formulation of the invention per day is sufficient for obtaining a therapeutic effect.
- the therapy may be continued for as long as necessary or desired.
- the formulations may be prepared by any of the methods well known in the art of pharmacy, for example, using methods such as those described in Gennaro et al., Remington's Pharmaceutical Sciences (18 th ed., Mack Publishing Company, 1990, see especially Part 8 : Pharmaceutical Preparations and their manufacture). Such methods include the process of bringing into association the active ingredient with the carrier which constitutes one or more accessory ingredients, carrying out said process by exclusion of contamination with traces of pathogens and harmful chemicals. Accessory ingredients include those conventional in the art, such as, fillers, binders, diluents, disintegrants, lubricants, colorants, flavoring agents and wetting agents.
- Formulations adapted for sublingual administration may be presented as liquid, solids or lozenges, which can comprise a rapidly disintegrating composition of a pharmaceutically acceptable water-soluble or water-dispersible carrier material.
- carrier materials are well known in the art and can be polysaccharides like hydrolysed dextran, dextrin, mannitol, and alginates, or mixtures thereof, or mixtures thereof with other carrier materials like polyvinylalcohol, polyvinylpyrrolidone and water-soluble cellulose derivatives, like hydroxypropyl cellulose.
- the adaptation of a formulation for sublingual administration is characterised by properties which are in favor of drug delivery within the buccal cavity and which are unfavourable for swallowing the formulation by the treated person.
- Such properties for a sublingual formulation may be obtained by methods available and/or known to the skilled person and comprise, for example the adjustment of the taste, the size or amount, the dosage, the surface, the viscosity and the disintegration time of the formulation.
- a small amount of a fluid formulation will be insufficient to swallow the administered dose.
- a solid formulation a pleasant taste, a very small size unsuitable for swallowing, a low dose insufficient for a therapeutic effect by oral administration but sufficient for sublingual administration, a rough or sticky surface in a moist environment, and disintegration time in a moist environment within 30 seconds or preferably 10 seconds, are all specific possibilities for implementing the adaptation for sublingual administration of the formulation.
- An example of a preferred carrier material for rapid disintegration of the formulation is gelatin, especially partially hydrolysed gelatin.
- the partially hydrolysed gelatin can be prepared be heating of a solution of gelatin in water, for example in an autoclave at about 120°C for up to 2 hours.
- the hydrolysed gelatin is used in concentrations of about 1 to 6 % (w/v), and preferably in concentrations of about 2 to 4 % (w/v).
- methods for preparation of sublingual dosage forms and packages are known to the skilled person and require no further elucidation. The details of preparing specific, preferred formulations and packages can be learned from the previously incorporated WO 95/23600, and the references mentioned therein.
- Formulations adapted for oral administration may be presented as discrete units such as tablets or capsules each containing a predetermined amount of active ingredient; as powder or granulates; as a solution or suspension.
- the active ingredient may also be presented as a bolus or paste, or may be contained within liposomes or microparticles.
- Formulations adapted for rectal administration may be presented as a suppository or enema.
- suitable formulations include aqueous and non- aqueous sterile injection.
- the formulations may be presented in unit-dose or multi-dose containers, for example sealed vials and ampoules, and may be stored in a freeze dried (lyophilised) condition requiring only the addition of the sterile liquid carrier, for example, water prior to use.
- Formulation adapted for nasal inhalation include fine dusts or mists which may be generated by means of metered dose pressurised aerosols, nebulisers or insufflators.
- Formulations may, for example, be presented in a suitable sustained release form, for example, in a device such as the MinipumpTM.
- the compounds of the invention may be prepared by any method known in the art for the preparation of a compound of similar structure. Typically the compounds are prepared by the methods described in US 4,145,434, which is incorporated herein by reference.
- Antidepressant-like drugs show a similar profile of action in this test: there is a decrease in overall responding, an increase in the number of food pellets earned per session and in the overall efficiency of performance (O'Donnell and Seiden J Pharmacol Exp Ther 224: 80-88; 1983).
- mice Male rats of the Long Evans strain, weighing between 300-425g, are used in these experiments. The experiments are run in standard Skinner boxes. All rats have previous training in the DRL-72 procedure. Rats are divided into separate groups and the experiment undertaken using an independent groups design. The number of lever presses and pellets obtained in each 1 hour session are recorded and an efficiency score (pellets earned/responses) is calculated. Statistical analysis is by one factor independent groups ANOVA, followed by post hoc Tukey HSD tests where overall significance is obtained. Vehicle: Mulgofen (5% m/v) and NaCI (0.9% m/v) in water. Route of administration: intraperitoneally (30 mins before session begins) Results
- the numbers in the table are means of 12 rats;
- Desipramine suppresses lever pressing in a dose-related manner and significantly increases the number of food pellets obtained and overall efficiency per session. This reflects the antidepressant effect of desipramine.
- the numbers in the table are means of 9 rats;
- ORG 5222 suppresses lever pressing in a dose-related manner and significantly increased the number of pellets obtained and overall efficiency per session. This reflects the antidepressant effect of Org 5222.
