Definitions
- This invention concerns novel methods for treating osteoporosis in humans and, more particularly, involves a method and composition for treating osteoporosis with a combination of alkalinizing potassium salt and an estrogen which is effective in such treatment and which reduces the health risks or side effects associated with conventional estrogen treatment of osteoporosis.
- Osteoporosis is a metabolic bone disease characterized pathologically by an absolute decrease in the amount of bone, and clinically by increased susceptibility to fractures.
- Riggs et al. N. En ⁇ l. J. Med. (1986), 314:1676; Rusbach et al., in: Textbook of Endocrinology., Ed(s) Williams, (1981), p. 922; Riggs, in: Cecil Textbook of Medicine. Ed(s) Wyngaarden et al., (1985), p. 1456; Riggs et al.. Am. J. Med.. (1983), 75:899.
- biochemical markers which taken together, can be used to either diagnose a patient as osteoporotic, or to study the efficacy of treatments for osteoporosis.
- urinary hydroxyproline excretion rate is widely used as a marker for bone resorption.
- Klein et al. Metabolism 2, Vol. 13, No. 3, March 1964, 272-285; Charles et al., J. Clin. Invest.. Vol. 76, December 1985 2254- 2258; and Deacon et al., Clin. Chim. Acta. r 1987, 297-306.
- Pyridinoline and deoxy-pyridinoline two types of collagen crosslinks present in bone, which can be detected in urine, are also markers for bone resorption.
- Osteocalcin is an integral protein of the organic matrix of bone synthesized by bone-forming cells (osteoblasts) during the process of bone formation. A small fraction of the newly synthesized osteocalcin escapes into the circulatory system, thus providing a blood marker of the rate of bone formation. The osteocalcin concentration increases when the bone formation rate increases, and decreases when the bone formation rate decreases. Brown, et al.. The Lancet. May 19, 1984, p.
- estrogens may pose serious health risks and side effects.
- the present invention involves a novel method for ameliorating or preventing osteoporosis in humans afflicted with or predisposed to osteoporosis, which comprises administering the combination of the following active ingredients:
- a pharmacologically-acceptable alkalinizing potassium salt which produces hydroxyl ions and is thereby capable of reducing the acidity (by increasing the alkalinity) of tissue fluids or urine, and which is selected from the group consisting of potassium bicarbonate and potassium salts of carboxylic acids which are transformed (combusted) to bicarbonate and thus alkalinize in vivo; and
- an estrogen which is effective in the treatment of osteoporosis, said estrogen being administered in an amount as small as 1/10 its normal recommended dose, preferably in an amount of from about 1/10 the normal recommended dose to the recommended dose or higher; the alkalinizing potassium salt being administered in an amount such that the combination of the two drugs is substantially more effective, generally from about 10% to as much as 50% or more, effective in treating osteoporosis than the same amount of the estrogen when independently administered.
- the present invention provides a more effective treatment for osteoporosis than conventional estrogen treatments.
- the amount of estrogen administered in the combination drug may be as low as about 1/10 the normal recommended dose of estrogen, as defined below.
- the combination of the lower dosages of estrogen, in conjunction with the alkalinizing potassium salts, in accordance with the present invention, is effective in the treatment of osteoporosis, and provides the significant benefit of reducing, if not eliminating, the health risks and side effects associated with conventional treatments with estrogen.
- Use of the alkalinizing potassium salt with the estrogen may obviate the necessity of co-administration of the estrogen with progestins; alternatively, the natriuretic properties of the alkalinizing potassium salt may offset the sodium- retaining characteristics of the progestins and thereby enhance the results obtained by combined estrogen-progestin- alkalinizing potassium salt therapy.
- the two active ingredients of the combination of the invention i.e., (a) the pharmacologically acceptable alkalinizing potassium salt and (b) an estrogen which is effective in the treatment of osteoporosis, may be administered as separate dosage forms in conjunction with one another, i.e., either at the same time or on different schedules.
- the alkalinizing potassium salt may be combined with the estrogen in a unitary dosage form which can be administered to subjects without the need for separate administration of these active ingredients.
- the terms “treatment” or “treating” cover any treatment of osteoporotic disease, and include: (1) preventing osteoporosis from occurring in a subject who does not have osteoporosis or who has not yet been diagnosed as having it; (2) inhibiting or arresting the development of the disease; or (3) regressing or reversing the osteoporotic state.
- the term "normal recommended dose” when used to refer to estrogen means an amount of estrogen which, when administered to a human being subject to osteoporosis is effective in treating osteoporosis, i.e., it causes the following effects in a human being: (a) reduces the urinary hydroxyproline excretion rate;
- (c) increases calcium and phosphorus balances, i.e., makes them less negative or more positive.
- the normal recommended dose of the estrogen known as conjugated estrogens (which is defined below) in the treatment of osteoporosis is 0.625 mg, administered on a cyclical basis, i.e., three weeks on, and one week off. See the Physicians Desk Reference, 1993 Edition, pages 2624-25. (The foregoing effects occur whether or not the estrogen is simultaneously administered with progestin.)
- references to the "same amount of said estrogen when independently administered" means an identical amount of the identical estrogen used in the combination drug of the present invention, which estrogen is administered without also administering the alkalinizing potassium salt ingredient of the combination drug of the present invention.
- the term “collagen crosslinks” means pyridinoline and deoxy-pyridinoline crosslinking.
- calcium balance means the difference between the total excretion (feces and urine) of calcium and the dietary intake of calcium.
- phosphorus balance means the difference between the total excretion (feces and urine) of phosphorus and the dietary intake of phosphorus.
- the alkalinizing potassium salts which may be employed in the process of the present invention are those which, when present in the body fluids, produce hydroxyl ions and are thereby capable of reducing the acidity (increasing the alkalinity) of tissue fluids or urine.
- a number of phar aceutically-acceptable alkalinizing potassium salts are known, several of which are set forth in Berg et al., J. Pharmaceut. Sci. (1977) 66:1, which is incorporated herein by reference. Given the disclosure herein, it will be well within the ability of one skilled in the art to select and screen pharmaceutically-acceptable alkalinizing salts for the ability to treat osteoporosis using well known methods and techniques. Desirably, a salt will be selected which is therapeutically effective in amounts readily achievable in humans while being relatively well tolerated. Different salts may be chosen depending on particular routes of administration and preferred modes of formulation.
- the alkalinizing potassium salts which may be thus administered are preferably selected from the group consisting of potassium bicarbonate (KHC0 3 ) and pharmacologically acceptable, non-toxic potassium salts of carboxylic acids such as potassium gluconate (C 6 H 11 K0 7 ) and potassium citrate (C 6 H 5 K 3 0 7 ) .
- KHC0 3 potassium bicarbonate
- pharmacologically acceptable, non-toxic potassium salts of carboxylic acids such as potassium gluconate (C 6 H 11 K0 7 ) and potassium citrate (C 6 H 5 K 3 0 7 ) .
- the use of potassium bicarbonate is particularly preferred.
- the preparation, isolation and purification of these salts are well known to those skilled in the art, as they are commonly employed in a therapeutic setting for a variety of uses other than described herein. Specific procedures for the preparation of such salts are described in general terms in Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, Pennsylvania, 16th Ed., 1982, which is incorporated here
- estrogen as used herein means any natural or synthetic substance possessing the biological activity of estrus-producing hormones, and which, is useful in the treatment of osteoporosis.
- Estrogens useful in the practice of the present invention preferably comprise those of the following formula, including pharmaceutically acceptable salts and esters thereof:
- R j and R 2 together represent an oxygen which is bound to the molecule by a double bond
- R 3 is either hydrogen or a hydroxyl group
- R 4 is selected from the group consisting of H, methyl, and cyclopentyl groups, and wherein the estrogen has either a double bond at the 6-7 and 8-9 positions, a double bond at the 7-8 position, or no double bonds at the 6, 7, 8 and 9 positions.
- the estrogens which may be thus administered in accordance with this invention include, but are not limited t all of the following estrogens and mixtures thereof: estrone (3-hydroxyestra-l, 3, 5 (10)-triene-17-one) ; 17?-estradiol (17S-estra-l,3,5(10)-triene-3,17-diol) ; 17 ⁇ -estradiol (estra- 1,3,5(10)-triene-3,17 ⁇ -diol) ; ethinyl estradiol (17 ⁇ -ethynyl- l,3,5(10)-estratriene-3,17
- conjugated estrogens means a mixture of conjugated estrogens from natural sources occurring as sodium salts of water-soluble estrogen sulfates blended to represent the average composition of material derived from pregnant mares' urine, the principal component of which is sodium estrone sulfate. Conjugated estrogens are . sold under the trademark "PREMARIN” by Wyeth-Ayerst Laboratories. See the Physicians Desk Reference, 1993 Edition pages 2624-26.
- Administration of the pharmacologically acceptable alkalinizing potassium salt or the estrogen ingredients of the combination drug of the present invention may be in pharmaceutical compositions described hereinafter and can be via any of the accepted modes of administration for agents which are known to be useful in the treatment of osteoporosis.
- these methods include oral, parenteral, and other modes of systemic administration. Different alkalinizing potassium salts may be admixed and simultaneously administered, or benefit may be gained in some instances by their separate, sequential administration.
- these methods include oral, parenteral, transdermal, and other modes of systemic administration.
- the alkalinizing potassium salt ingredient may be in the form of solid, semi- solid or liquid dosage forms, such as, for example, tablets, capsules, pills, powders, granules, crystals, liquids, suspensions, or the like, preferably in unit-dosage forms suitable for administration of relatively precise dosages.
- the estrogen ingredient may be in the form of a solid tablet, capsule or pill, preferably in unit-dosage forms suitable for administration of relatively precise dosages.
- the alkalinizing salt and estrogen active ingredients are combined in a solid unitary dosage form in a tablet, capsule or pill, thus obviating the need for separate administration of these ingredients.
- the solid combined dosage form may include conventional pharmaceutical carriers or excipients, and, in addition, may include other pharmaceutical agents.
- the unit dosage form may be compounded with conventional nontoxic solid carriers such as, for example, pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, talcum, cellulose, glucose, sucrose, magnesium carbonate, and the like.
- Such compositions may contain about 50-90% of the active ingredients of the present invention, preferably about 70-90%.
- the alkalinizing potassium salt ingredient may be administered as a separate dosage form, in conjunction with the administration of the estrogen active ingredient.
- the two drugs may thus be administered on the same schedule or on different schedules in accordance with the normal modes of administration thereof.
- the alkalinizing potassium salt ingredient may be in the form of tablets, pills, capsules, powders, granules, crystals, sustained-release formulations. and the like, with any of the previously listed excipients, or may be administered in a liquid pharmaceutically-administrable composition.
- Such liquid compositions can be prepared, for example, by dissolving the salt, such as potassium bicarbonate, and optional pharmaceutical adjuvants in a carrier, such as, for example, water, aqueous dextrose, glycerol, and the like, to thereby form a solution or suspension.
- a carrier such as, for example, water, aqueous dextrose, glycerol, and the like
- the separate alkalinizing salt dosage form may also contain minor amounts of nontoxic auxiliary substances such as pH buffering agents and the like, for example, sorbitan.monolaurate, triethanolamine, sodium acetate, triethanolamine oleate, etc.
- An active potassium salt ingredient of the combination drug such as potassium bicarbonate, for example, may be provided as a dietary supplement supplied as pills, as granules or powder applied directly to foodstuffs, or dissolved in drinking water, as convenient means of administration.
- the estrogen ingredient of the combination drug of the present invention may be administered in an amount of as little as about 1/10 of its normal recommended dose.
- the alkalinizing potassium salt ingredient of the combination drug is administered in an amount such that the combination drug is about 10% more, or as much as 50% or more, effective in treating osteoporosis than the same amount of the estrogen when independently administered.
- the estrogen ingredient is orally administered in an amount equivalent (on a daily basis) to about 0.06 to 1.25 mg, preferably about 0.06 to 0.625 mg of the conjugated estrogens.
- the amount of the alkalinizing potassium salt administered in the combination drug is about 30-120, preferably about 30 to 60, milliequivalents.
- the combination of the active ingredients of the present invention exhibits a synergistic effect in treating osteoporosis, i.e., the combination of the two drugs is substantially more effective than the same amount of the estrogen when independently administered.
- the estrogen ingredient may be administered in an amount equivalent to the oral administration of as little as about 0.06 mg of conjugated estrogens.
- the lower dose of estrogen is not only effective in treating osteoporosis, but also significantly reduces the health risks and side effects associated with estrogens at conventional doses.
- the amount of the estrogen ingredient administered in accordance with the present invention will, of course, be dependent on the potency of the particular estrogen(s) used and the mode of administration.
- the relative and equivalent potencies of various estrogens are well known to those skilled in the art.
- 0.6 mg of conjugated estrogens are equivalent to 2.0 mg of micronized 173-estradiol in terms of estrogenic potency and ability to treat osteoporosis.
- it will be well within the ability of one skilled in the art to select an estrogen and a dose level equivalent to the estrogens and the dose levels described herein.
- the combination drug of the present invention may be administered on a daily basis continuously, or instead, may be administered on a cyclical basis, i.e., three weeks on, and one week off. It will also be appreciated by those having skill in the art that in addition to administering the combination drug described herein, it may be desirable to supplement the patient's calcium intake, if necessary, to maintain it at 1500 mg of calcium per day.
- a combination drug tablet is prepared containing the following active ingredients: 0.156 mg of conjugated estrogens and 1.5 grams of potassium bicarbonate. Four such tablets may be suitably administered daily.
- a combination drug tablet is prepared containing the same ingredients as Example I and administered in accordance with the same protocol, except that each tablet contains only 0.08 mg of conjugated estrogens and 0.75 grams of potassium bicarbonate.
- the present invention provides a novel method and composition which effectively treats/prevents osteoporosis in human subjects, with lower health risks and incidence of side effects than associated with conventional hormonal treatments for osteoporosis.
