Description
The application is dividing an application of application number 200480014128.8, June 17 2004 applying date, denomination of invention " pharmaceutical composition of hydrochloric benidipine ".
Technical field
The present invention relates to contain the pharmaceutical composition of KW-3049 (Benidipine Hydrochloride), wherein contain the KW-3049 KW-3049 fast Absorption, that have quick stripping property that is useful on promotion drug main composition.
Background technology
KW-3049 belongs to dihydropyridine type calcium antagonists, because it is not only safe but also effectively used widely as the medicine of hypertension, the substantive hypertension of kidney, angina pectoris etc.And; other calcium antagonist of KW-3049 and nifedipine or amlodipine etc. is different; known it act on osteoblast and bone sprout cell and do not damage bone formation; has the bone protective effect; and known it can strengthen to generally believe it is the alkaline phosphatase activity of making the bone active index, make it the function that acts on bone metabolism and stimulate the bone sprout cell.[Calcified Tissue International rolled up, p.554-556] in 1998, the 62nd still not know nifedipine noted earlier or amlodipine to have this effect.In addition, KW-3049 also demonstrates sclerotin increase effect and bone strength increase effect in the osteoporosis model of rat, and can observe sclerotin increase situation by the X ray examination.Promptly point out KW-3049 it in the balance of bone metabolism, more deflection help bone protection one side [new drug with clinical, the 42nd roll up, o.11 do not print (putting down in November, 5), (2298)-66 (2306) P.58].And the sclerotin protective effect of known this serial KW-3049 is to realize by the relevant parathyroid hormone Calcium Metabolism Regulation hormones such as (PTH) of bone metabolism, and prompting because the fast Absorption of KW-3049 and rapidly in the blood that caused of metabolism the moment property rising of parathyroid hormone help the formation of bone.But the long-time rising of parathyroid hormone brings harmful effect to bone metabolism on the contrary in the known blood.
For the above reasons, for avoiding that bone metabolism is brought this side effect of harmful effect, people wish to develop a kind of pharmaceutical composition that can promote hydrochloric benidipine its fast Absorption, that have quick stripping property.
