Description

Omeprazole for treatment of diseases related to bone loss.
Field of the Invention
The present invention is related to a novel method for the treatment of several bone affecting diseases, especially osteoporosis, which are characterized by loss of bone mass.
Background of the Invention
The balance in normal subjects between, on one hand, bone formation, which is associated with the number and activity of osteoblasts, that is cells associated with the production of bone in the organism, and on the other hand, bone loss which is associated with the number and activity of osteoclasts, that is cells associated with the absorption and removal of bone, is disturbed in several bone affecting diseases. At the present time there is no good treatment for any of these diseases, among which can be mentioned osteoporosis, Paget's disease of bone, hyperparathyroidism and related disorders, and several malignant neoplasms where tumor cells are producing osteoclast- activating factors and cause hypercalcemia.
Worldwide the most urgent need is for the treatment of osteoporosis and tumor associated hypercalcemia. In some areas, e.g. in England and in some other parts of Europe there is also high incidence of Paget's disease of bone.
In osteoporosis bone formation as well as bone resorption are disturbed, resulting in loss of bone tissue, decreased bone mass, and bone fragility. Osteoporosis predominantly affects the elderly, but also other groups such as postmenopausal women, where an estrogen deficit is believed to be a significant etiological ctor,.and immobilized patients. At this point it is not possible to clear up the whole picture of the disease mechanism and estimate which is the primary cause of osteoporosis. However, about 25% of the osteoporotic females belong to what is called "rapid bone losers" and at least in those patients the bone resorption rate is probably increased. Landry and Fleisch showed in immobilization induced osteoporosis that bone resorption rate was accelerated, (Landry, M. and Fleisch, H. : The influence of immobilization on bone formation as evaluated the incorporation of tetracyclines. J. Bone Joint Surg. 4βB:764, 1964) .
The clinical manifestations of osteoporosis comprise fractures, especially hip fractures, but also vertebral fractures and fractures of the proximal radius, and complication of such fractures.
In Finland it has been estimated that about 10% of all surgical hospital beds are used for the treatment of osteoporosis related fractures (Lϋthje, P.: Reisiluunkaulan ja trokantterin murtumapotilaiden hoito ja ennuste seka hiodon kustannukset. Thesis. Helsinki 1983).
The present methods for the treatment of osteoporosis include exercise; administration of estrogen, especially for postmenopausal women; and consumption of calcium or calcium containing material such as milk. Calcitonin, a hormone associated with calcium metabolism, has also been used in the treatment of osteoporosis.
Several malignant tumors are known to be associated by hypercalcemia which is due to increased osteoclastic activity. s s a common comp ca on or ns ance n e case o breast cancer and prostate cancer which are both one of the most common malignant tumors. Hypercalcemia is due to both systemic and local factors. Some malignant cells are known to secrete agents which stimulate bone resorption (Sato, K. ,
Fujii, Y., Kachivehi, T., Kasono, K., Shizume, K. : Production of interleukin 1 alpha (IL-lα)-like activity and colony stimulating activity by clonal squanous cell carcinomas derived from patients with hypercalcemia and leucocytosis. In: Calcium
Regulation and Bone Metabolism Vol. 9 (eds. D.V. Cohu, T.J.
Martin, P.J. Meunier) , 1986).
In malignant hypercalcemia calcϊtonin and diphosphonate treatment has been used.
Paget's disease (or osteitis deformans) of bone is a disease of unknown etiology where bone resorption and remodelling are increased leading sometimes even to the fractures of affected bone. Bone pain is the main indication of treatment in these patients. In these patients there is highly elevated local osteoclastic bone destruction. The incidence of osteitis deformans is very low in Scandinavian countries. In England it has been estimated to be present in 3-4% of the population on the basis of autopsy studies (Anderson's Textbook of Pathology 1986). It is very rare in patients under 40 years. Calcitonin and diphosphonates are also used in the treatment of Paget's disease.
Other disease states for the treatment of which antagonists to osteoclastic activity might be useful, are parodontal diseases and prostetic and implant bone losses. It is an object of the present invention to provide compounds which by affecting the balance between osteoblast and osteoclast activity can be useful for prophylactic and therapeutic treatment of diseases as indicated above which are associated with bone loss. It is believed that the use of these compounds will also ultimately result in an increase of the bone mass.
Outline of the invention
According to the present invention it has been found that the compound omeprazole, 5-methoxy-2-[ (4-methoxy-3,5-dimethyl- 2-pyridinyl)methyl]-sulfinyl]-IH-benzimidazole, of the formula

H
or a prodrug or a therapeutically acceptable salt thereof, is useful in the prophylactic and therapeutic treatment of osteoporosis; Paget's disease of bone; hyperparathyroidism, both primary and secondary; malignant neoplasms where tumor cells are producing osteoclast-activity factors and cause hypercalcinemia; immobilization-induced osteoporosis; parodontal diseases; and prostetic and implant-related bone losses. Examples of pharmaceutically acceptable salts are alkali salts such as sodium and potassium salts, and calci -r- and magnesium salts. The term "prodrug" is intended to cover compounds which after administration to the patient, are converted to a compound of the formula I. More particularly, examples of prodrug of compounds the formula I are of the formula

Pharmacological tests
Sprague-Dawley male rats (Alab, Stockholm, Sweden) weighing 175-200 g before the tests were used. They obtained a standard diet consisting of rat feed pellets (Alab, Stockholm, Sweden) and tap water. Ten rats were given omeprazole (Hassle, Sweden) , 400 μmol/kg body weight, once daily orally during 26 days. Twelve rats were used as untreated controls.
45Ca incorporation into the skeleton
2x106 cpm 45CaCl2 (Radiochemical Center, Amersham, England) were administered orally by ventricular sond. The rats were killed by tapping blood via abdominal aorta 4 hours after the peroral administration of Ca. Radius, sternum, tibia and femur were removed by dissection. Radius and sternum were cleaned, weighed and placed in an oven at 800°C during 24 hours. The ashes were weighed and dissolved in 1M HC1. 10 ml Picofluor-40 (Packard) was added, whereafter the tubes were closed and shaken vigourosly before counting in a Beckman B- counter.
Radioimmunoanalysis of crastrin
Serum was prepared at the blood tapping from each rat and gastrin was determined by radioimmunoanalysis (Stadil, F. & Rehfeld, J.F. (1973) Determination of gstrin in serum. An evaluation of the reliability of a radioimmunossay, Scan. J. Gastroent. 8, 101-112; H kanson, R. , Kroesen, J.H., Liedberg, G., Oscarson, J., Rehfeld, J.E. & Stadil, F. (1974) Correlation between serum gastrin concentration and rat stomach histidine decarboxylase activity, J. Physiol. 243, 483-498).
Operations were performed under ether anaesthesia. Fundectomia, comprising resection of the acid producing part of the ventricle, was performed as has been described in detail by
Alumets et al (Alumets, J. , EΪ Munshid, H.A., Hakanson, R.,
Hedenbro, J. , Liedberg, G. , Oscarson, J., Rehfeld, J.F.,
Sundler, F. and Vallgren, S., Gastrin cell proliferation after chronic stimulation. Effects of vagal denervation or gastric surgery in the rat. J. Physiol. 298, 557-569 (1980)).
Gastrectomia was prepared by resection of the stomach followed by suturation of eosophagus and duodenum end to end. Operated animals were allowed to recover for one week before treatment with omeprazole, as has been described in "Pharmacological tests".
The test results are given in Fig. 1 and Fig. 2.
Description of the drawing's
Fig. 1 shows the concentration of gastrin expressed as picogram/ml serum with untreated control rats (average of 12 rats respectively average of 7 rats) and with omeprazole- treated rats (average of 10 rats) after treatment for 26 days. Fig. 2 shows the amount of radioactive calcium which has been incorporated into the skeleton (radius respectively sternum) expressed in cpm/mg bone ashes. A shows the average of 12 control rats, B shows the average of 10 omeprazole-treated rats, C shows the average of 12 control rats, D shows the average of 10 omeprazole-treated rats.
The continuous lines represent the average of given number of rats and the dashed lines represent the standard error of the average value. The stars designate the significance (i.e. the difference between control and test substance according to Student's t-test p < 0.05 = x; p < 0.01 = xx and p < 0.005 =
XX ) . Results
Omeprazole-treated rats and fundectomized rats developed pronounced and constant hypergastrinemia, which is seen in the attached Fig. 1. The hypergastrinemia which had been developed by treatment with omeprazole-stimulated Ca-incorporation into the skeleton, which is seen in the attached Fig. 2. Hypergastrinemia caused by fundectomia did not stimulate ^Ca- incorporation into the skeleton. Neither did omeprazole- treatment in gastrectomized rats stimulate
Figure imgf000013_0001
into the skeleton.
The tests given above showed clearly that treatment with omeprazole led to increased incorporation of calcium into the skeleton. This may be due to hypergastrinemia which in turn via some factor in the acid-producing part of the stomach seems to control the incorporation of calcium into skeleton.
