Definitions

  • the present invention relates to orally administered, film-shaped medicaments for the transmucosal administration of estriol and / or at least one of its pharmacologically acceptable esters, alone or in combination with at least one gestagen.
  • the present invention also relates to the use of estriol and / or at least one of its pharmacologically acceptable esters, alone or in combination with at least one gestagen, for the production of a fil-shaped, orally administered medicament for the treatment of menopausal symptoms.
  • menopause is a phase of life that separates the fertile phase and the time in which reproduction is no longer possible.
  • the menopause is characterized by a permanent decrease in the hormone production in the ovaries as well as the associated decrease and finally the absence of the monthly menstrual period.
  • the level of progestin in the blood drops and, after a few years, less estrogen is produced until the body completely stops producing hormones.
  • the organic complaints can be accompanied by neurovegetative complaints such as hot flashes, sweating, sleep disorders, dizziness, rapid heartbeat or headache. These symptoms shape the picture of climacteric complaints for about 2 to 3 years.
  • Psychological complaints can also occur. These include anxiety, irritability and aggressiveness, inner tension, disaffection, nervousness, mood swings and depressions, tiredness and lack of drive, forgetfulness, a reduced ability to concentrate and an altered sexuality. These symptoms usually subside when the organism has got used to the hormone deficiency.
  • hormone replacement therapy In order to compensate for the hormone deficit and to treat the symptoms associated with the menopause, so-called hormone replacement therapy (HRT) combines estrogens with progestogens administered.
  • HRT hormone replacement therapy
  • hormone replacement therapy can also have undesirable side effects.
  • the most common side effects include increased edema formation, an increased risk of thrombosis, an increased risk of developing endometrial cancer, chest tightness, weight gain, nausea, hyperpigmentation and spotting.
  • hormones that act as hormones promotes the proliferation of vaginal epithelial cells and increases the risk of endometrial hyperplasia.
  • estriol instead of estradiol as part of a hormone replacement therapy, which hardly induces proliferation of the endometrium.
  • Estriol ((16 ⁇ , 17ß) -Estra-1, 3, 5 (10) -triene-3, 16,17-triol) is the final and usually predominant urine metabolite of estrogen metabolism.
  • estriol is also much less hormonally effective than estradiol.
  • estriol when taken orally in the form of coated tablets, capsules or tablets, estriol is quickly inactivated in the liver by forming its glucoronide derivative. Only 1 to 2% of the administered estriol dose gets into the bloodstream in bioavailable form.
  • estriol when estriol was given orally, a dose of 2 mg per day was found to be optimal for preventing vaginal atrophy and effective in treating hot flashes, sleep disorders and some other climacteric problems.
  • side effects such as nausea and mastalgia can also occur.
  • vaginal administration of estriol was also tested in order to be able to reduce the amount of hormone to be administered with the same systemic effect.
  • a lower dose also has the advantage of less deflection of estrogen-modulated liver functions.
  • Vaginal administration proved to be more effective than oral administration, since intravaginally administered estriol was initially quickly absorbed and is therefore basically suitable for local and systemic hormone replacement therapy.
  • the cornification of the vaginal epithelium that occurs during prolonged use speaks against vaginal application of estriol, which has a negative effect on the absorption of estriol.
  • vaginal administration of estriol was not accepted by the subjects.
  • estriol administered transdermally is also suitable for the therapy of climacteric osteoporosis.
  • the very high amounts of estriol (12 mg per 24 hours) that are continuously administered transdermally to the male test subjects are to be regarded as disadvantageous to reach a serum level of free estriol that corresponds to the physiological concentrations of estrogen hormones in the woman's cycle (50 to 350 ⁇ g / ml).
  • estriol should lead to a largely constant blood level of estriol, which has a beneficial effect on the bones, but which also promotes the undesirable effects in the uterine mucosa.
  • estriol and / or the pharmacologically acceptable ester (s) of estriol can be used in combination.
  • combination with at least one gestagen can be contained in the film-shaped medicament.
  • the film-like medicaments according to the invention enable the transmucosal absorption of estriol and / or the pharmacologically acceptable ester (s) of estriol and optionally the progestogen (s) additionally contained in the medicinal product via the oral mucosa by applying the medicinal product sublingually or buccally becomes.
  • the active substance contained in the film-shaped medicament or the active substances contained in the film-shaped medicinal product are released from the film-shaped medicinal product due to the action of saliva and can / can subsequently be resorbed via the oral mucosa. In this way, the so-called "first pass effect", which is responsible for the rapid inactivation of orally administered estriols, is avoided.
  • the dose of estriol or estriol ester to be administered with the film-like medicament according to the invention can be based on the known dosage forms for estriol, can be reduced to less than 2 mg / 24 h, preferably to about 200 ⁇ g per 24 h, which the medicament according to the invention releases in order to achieve the same systemic effects as with significantly higher doses of orally or transdermally administered estriols.
  • the film-like dosage forms according to the invention are medicaments of small thickness.
  • the thickness of these film-shaped pharmaceuticals is 0.01 mm to 5 mm, preferably 0.03 mm to 3 mm, particularly preferably 0.05 mm to 2 mm and very particularly preferably 0.1 mm to 1 mm.
  • the area of the pharmaceuticals according to the invention is between 0.5 and 20 cm 2 , preferably the area is 1 to 10 cm 2 .
  • each drug can vary. They can have a round, oval, triangular, quadrangular or polygonal shape.
  • the medicaments according to the invention are also referred to as “wafers”. They are able to adapt to the irregular surface contour of the oral mucosa after absorbing moisture.
  • the medicaments according to the invention can be gellable or swellable.
  • the film-like pharmaceutical preparations according to the invention are flexible before they are applied and can absorb moisture from the saliva.
  • the active substance content of a film-like pharmaceutical preparation according to the invention is 0.5 to 40% by weight, preferably 1 to 30% by weight, and particularly preferably 5 to
  • the film-like medicaments consist of one or have at least one polymer-containing layer which serves as an active substance reservoir.
  • This layer contains the active ingredient and can release it under the influence of saliva.
  • the polymer content in this polymer-containing reservoir layer is 10 to 90% by weight, preferably 20 to 70% by weight, and particularly preferably 30 to 60% by weight.
  • the polymers suitable for the production of the active substance reservoir layer can be selected from the group consisting of polyvinyl alcohols, polyvinyl pyrrolidones, polyvinyl acetates, polyethylene glycol, polyethylene oxide polymers, polyurethanes, polyacrylic acids, polyacrylates, polymethacrylates, poly (methyl vinyl ether-maleic anhydrides), starch, starch , natural gums, alginates, pectins and gelatin pullulan, gel-forming proteins, chitosan, agar-agar, agarose, carragenan, xanthan, tragacanth, dextran and cellulose ethers such as ethyl cellulose, hydroxyethyl cellulose, propyl cellulose, carboxylmethyl cellulose, Na Carboxy ethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl ethyl cellulose, cellulose acetate.
