В литературата няма данни за прилагане на ИНД при остеопороза. Повлияването на костната минерална плътност от 6-месечен лечебен курс на 20 пациенти с ХХТ 25 mg и 11 с ИНД 2,5 mg се отчете с LUNAR DPXA – X-ray bone densitometer. Ефектът при двете групи е съизмерим, почти еднакъв, като се отчете статистически значимо подобрение (р < 0,05). ИНД се препоръчва като по-добра и безвредна алтернатива на тиазидите при лечението на реналната хиперкалциурия при нефролитиаза. Резултатите от настоящото проучване дават основание за прилагане на ИНД и при остеопороза.

calcinosis due to renal hypercalciuria and osteoporosis. During the first stage of the study for periods of 10 days, 20 patients are treated consecutively with HHT 12,5 mg, 25 mg, 50 mg, and IND 2,5 mg daily. Dose dependent effects of HHT are observed. The effect of IND 2,5 mg is equal to that achieved with 50 mg HHT and greater than the doses of 25 mg and 12,5 mg HHT daily. During the second stage of the study are compared the effects of IND 2,5 mg (a group of 20 patients), HHT 25 mg (28 patients) and HHT (12 patients) over a 6 months period. The lowest and sustained calciuric effect is achieved with 2,5 mg IND – x ± SD = 0,052 ± 0,012 mmol/kg/24 h. Almost the same are the results with 25 mg HHT – x ± SD = 0,076 ± 0,01 mmol/kg/ 24 h, but undesired adverse effects are observed – hypokalemia, hyperglicemia, hyperuricemia and hyperlipoproteinemia, which are absent during treatment with IND. Lower doses of HHT (12,5 mg/24 h) prove metabolically safe, but their hypocalciuric effect is unsatisfactory. There are no available data in the literature about the use of IND in the treatment of osteoporosis. Changes in bone mineral density (BMD) are measured in 20 patients treated with HHT 25 mg/24 h and 11 treated with IND 2,5 mg/24 h for 6 months by dual-energy X-ray absorbtiometry (LUNAR – X-ray bone densitometer). In both groups the changes of BMD are similar and statistically significant (p < 0,05). We can recommend IND as a better and safer alternative of the thiazides in treating renal hupercalciuria associated with recurrent renal stones. The results of the study show that we can use IND also in the treatment of osteoporosis.
