Methods and compositions useful for the treatment and prophylaxis of calcium renal stones in persons with hypocitraturia or undergoing allopurinol therapy are disclosed. The methods involve administering potassium citrate compositions to persons afflicted with or susceptible to calcium renal stone formations. A typical dosage scheme involves administering about 30 to 120 meq potassium citrate per day in divided doses. Such treatments are effective in dissolving existing calcium stones and preventing formation of new calcium stones. Moreover, the results of a comparative clinical assay indicate the potassium citrate is superior to sodium citrate in the treatment of uric acid lithiasis. Potassium citrate therapy averts calcium renal stone formation, a complication which is often associated with sodium citrate or sodium bicarbonate alkalinization therapy.

Disclosed is a region on human chromosome 1 that provides a genetic basis for absorptive hypercalciuria. The genes, proteins, and other biological materials provided are envisioned for use in diagnostic and therapeutic methods related to absorptive hypercalciuria and osteoporosis with hypercalciuria.
摘要:
A method for supplementing dietary potassium, magnesium and citrate is disclosed that comprises orally administering an effective amount of potassium magnesium citrate in a single salt. Methods for decreasing urinary calcium and oxalate by the administration of potassium magnesium citrate in a single salt are also disclosed.
摘要:
A urine specimen is preserved from bacterial deterioration as to relative constituents by adding thymol. To the thymol-treated specimen, lithium-solution volume-marker is added, then is divided into two (first and second) separate portions. Thereupon, using the first portion, standard conventional measurements and/or analysis is conducted for total volume, pH/acidity, uric acid, citrate, sodium, and potassium. To the second portion, there is added boric acid and hydrochloric acid, followed by standard/conventional measurement and/or analysis for ammonium ion, citrate, calcium, magnesium, phosphorus, oxalate and sulfate. Thereafter the findings are charted and compared to controls.
摘要:
A composition comprising a powder mixture of potassium citrate and calcium citrate as mixtures of pure chemical salts and methods of making and using the composition are disclosed. The composition is useful for the treatment and prevention of kidney stones and osteoporosis and better delivers potassium and calcium than commonly used potassium and calcium supplements.
摘要:
One aspect of the present invention includes the novel compound having the formula:Ca.sub.2 (OOC--CH.sub.2 --COHCOO-CH.sub.2 COO)(CH.sub.3 CHOH-COO)In another aspect of the present invention, a method is provided for the treatment of a calcium related pathology. The inventive method includes the steps of providing a pharmaceutically acceptable composition, including as the active principle the compound dicalcium citrate-lactate, and administering to an individual in need thereof a therapeutically effective amount of said pharmaceutically acceptable composition.In yet another aspect of the present invention, a process is provided for producing the compound dicalcium citrate-lactate. The inventive process comprising the steps of: (a) admixing stoichiometric quantities of citric acid and a calcium compound selected from the group consisting of calcium carbonate, calcium oxide and calcium hydroxide; (b) initiating a reaction by admixing stoichiometric quantities of lactic acid and water with said citric acid and calcium compound of step (a); (c) mixing the reactance of step (b) to produce a dense, hydrated mixture comprising calcium ions, citrate ions and lactate ions in a ratio of about 2:1:1; and (d) dehyrating the dense, hydrated mixture of step (c).
摘要:
A novel slow-release sodium fluoride preparation and its use. Such slow-release sodium preparation comprises carnauba wax and talc and may be used to provide a safe but effective level of fluoride in serum, optimal for the treatment of osteoporosis. Gastrointestinal side effects are minimized by limiting the amount of fluoride released in the stomach and rheumatic complications are reduced by avoiding toxic levels of fluoride is serum. The amount of fluoride absorbed is nevertheless sufficient to stimulate bone formation and prevent fractures. Thus, the maintenance of serum fluoride as encompassed in this invention, allows for a safe and effective treatment of osteoporosis.
