Definitions

  • the present invention relates to therapeutic agents that bind to the estrogen receptor and cause tissue specific estogen agonist effects, that have been found to be useful in the treatment of the symptoms of atrophic vaginitis and altered sexual behavior in postmenopausal women.
  • Menopause and the perimenopause in women are often marked by the occurrence of symptoms relating to loss of estrogen stimulated vaginal secretions (atrophic vaginitis). Alterations in sexual behavior are also common at the time
  • HRT hormone replacement therapy
  • HRT hypothalamic hormone
  • This invention provides a method for the prevention and treatment of the symptoms of atrophic vaginitis and altered sexual behavior in postmenopausal women without the side 30 effects of Hormonal Replacement Therapy (HRT).
  • the method comprises administering to a human in need thereof an effective amount of a therapeutic agent that binds to the estrogen receptor and produces a tissue specific estrogen agonist effect in the vaginal and cervical glandular/epithelial cells or the specific areas of the brain that control sexual behavior.
  • a therapeutic agent that binds to the estrogen receptor and produces a tissue specific estrogen agonist effect in the vaginal and cervical glandular/epithelial cells or the specific areas of the brain that control sexual behavior.
  • compounds that can be utilized in this invention are compounds of formula I
  • X represents 3- or 4- iodo or bromo and the R* and R ⁇ symbols, which may be the same or different, represent C ⁇ _3 alkyl, especially methyl or ethyl, groups or R! represents a hydrogen atom and R ⁇ a C ⁇ _3 alkyl group or R ! and R ⁇ together with the nitrogen atom to which they are attached represent a saturated heterocyclic group, typically having 5 or 6 ring atoms, especially a pyrrolidino, piperidino, 4-methylpiperidino or morpholino group, and their pharmaceutically acceptable acid addition salts.
  • Preferred is the compound known as idoxifene.
  • the present invention is a therapeutic method for treating the symptoms of atrophic vaginitis and altered sexual behavior in postmenopausal women with agents that bind to the estrogen receptor and, as a consequence of that interaction with the estrogen receptor, cause either estrogenic (estrogen agonist) or antiestrogenic (estrogen antagonist) effects in different tissues.
  • estrogenic estradien agonist
  • antiestrogenic estradien antagonist
  • the same agent may be estrogenic in one tissue but antiestrogenic in another.
  • Some compounds of this description are in clinical use because of the beneficial effects that are produced in specific tissues as a result of binding to the estrogen receptor (for example the use of the antiestrogenic effects of tamoxifen in breast tissue to provide therapeutic benefit in the treatment of breast cancer).
  • the preferred effect of a compound for the desired method of treatment is to produce estrogenic effects in the vaginal epithelial and cervical glandular cells or the specific areas of the brain that control sexual behavior. This would have the clinical effect of reducing the severity of vaginal itching and dryness, pain on sexual intercourse and decreased libido by having the same effect as estrogen in these tissues.
  • An example of such a compound is idoxifene.
  • Preferred compounds are described in formula I above and in U.S. patent 4,839,155.
  • the preferred compound for the described method of treatment is
  • the symptoms that would be treated in this invention are an important component of a menopausal syndrome that also includes vasomotor symptoms (hot flashes), sleep disturbance, agitation, nervousness, mood changes, anxiety, irritability, loss of memory and concentration, crying spells, tiredness, depression, headache, and joint or muscle pain.
  • vasomotor symptoms hot flashes
  • sleep disturbance agitation
  • nervousness mood changes
  • anxiety irritability
  • loss of memory and concentration crying spells
  • crying spells tiredness, depression, headache, and joint or muscle pain.
  • idoxifene caused a dose related protection from the loss of vaginal epithelial stratification/cornification and cervical mucus secretion that was observed in the ovariectomized control animals.
  • a questionaire was also administered to the patients to provide information about the severity of the other symptoms that comprise the menopausal syndrome including those that would be treated in this invention.
  • a loading dose regimen was employed which involved taking three tablets as a single daily dose for the first week and one tablet per day thereafter. Analysis of the data from the patient questionaire revealed that the responses to the questions on sexual function were significantly improved from baseline in the group of patients who received 5mg/day of idoxifene.
  • the compounds of the instant invention and their pharmaceutically acceptable salts which are active when given orally can be formulated as liquids, for example syrups, suspensions or emulsions, tablets, capsules and lozenges.
  • a liquid formulation will generally consist of a suspension or solution of the compound or pharmaceutically acceptable salt in a suitable liquid carrier(s) for example, ethanol, glycerine, non-aqueous solvent, for example, polyethylene glycol, oils, or water with a suspending agent, preservative, flavouring or coloring agent.
  • a suitable liquid carrier(s) for example, ethanol, glycerine, non-aqueous solvent, for example, polyethylene glycol, oils, or water with a suspending agent, preservative, flavouring or coloring agent.
