Described vitamins D2With D3The advantage that eutectic has degree of crystallinity height, water absorbability is little, and form regular crystal kenel, stability significantly strengthens, and is thus conducive to the art breading of medicine and the improvement of physical and chemical performance, it is to increase patent medicine performance.

Description

Eutectic of vitamin D2 and D3 and its production and use
Technical field
The invention belongs to pharmaceutical chemistry and crystallization processes technical field, it is specifically related to vitamins D2With D3Eutectic and its production and use.
Background technology
Medicine cocrystallization (eutectic) refers to that the acid physiologically acceptable with other of active constituents of medicine (API) molecule, alkali, salt, non-ionic compound molecule are connected and be combined in same lattice with other non covalent bonds with hydrogen bond, pi-pi accumulation effect, Van der Waals force. The using value maximum in medicine of eutectic is exactly to introduce new component while not changing medicine covalent structure, greatly improve the physico-chemical property of medicine, such as stability, fusing point, dissolution rate, dissolution rate, bioavailability etc., and owing to the kind of part (CCF) has a lot, the character of medicine corresponding can also obtain adjustment in various degree. The difference of the physical properties that the solid form that each of active pharmaceutical ingredient is new shows can affect its stability in storage, compressibility and density and solubleness and dissolution rate.
Compared with other solid form such as salt, solvate, eutectic has bigger advantage in medicament research and development. First, for solvate, because the solvent species that can accept in pharmaceutics is limited, and often there is desolventizing (water) phenomenon in solvate in production process, is changed into the worse brilliant type of unstable amorphous or solvability. Secondly, relative to salt, because becoming salt to require, bulk drug has at least the center of an ionization, and each component in medicine eutectic can be neutral molecule, and thus medicine eutectic can contain all API, comprises acid, alkali and non-ionic compound; Further, the potential molecule being used for being formed eutectic with API is also a lot, and these materials may comprise foodstuff additive, sanitas, pharmaceutical excipient, mineral substance, VITAMIN, amino acid and other bioactive molecules, it is even possible that be other API. Generally speaking, eutectic is a kind of solid form having wide application prospects, and preformulation study and dosage form design to medicine have profound influence.
A kind of eutectic is due to its specific crystal habit and specific chemical composition, it is possible to have unique character. Such as, compared with API, eutectic has better pharmacology and pharmacological properties, more easily processes; Eutectic has dissolution rate and the solubleness of the advantage of having more, and human body can be made more to effectively utilize active constituents of medicine, therefore have better bioavailability; Eutectic has better stability in storage. In a word, eutectic may have other the favourable character except result for the treatment of.
Vitamins D (vitaminD) is sterol analog derivative, and tool rickets effect, also known as antirachitic vitamin. It is now recognized that vitamins D is also a kind of steroid hormone, in vitamins D family member, the most important member is D2(ergocalciferol) and D3(cholecalciferol). Vitamins D2(vitaminD2) chemistry be called: 9,10-open loop ergot steroid-5,7,10 (19), 22-tetra-alkene-3-alcohol, its chemical structural formula is as follows:
Vitamins D3(vitaminD3) chemistry be called: 9,10-open loop courage steroid-5,7,10 (19)-triolefin-3-alcohol, its chemical structural formula is as follows:
Vitamins D2And D3In body after liver, kidney metabolism, have and promote that small intestine is to the effect of calcium absorption, can be used as the adjuvant drug of calcium deficiency patient. Due to vitamins D2And D3Instability, to light, thermo-responsive, loses activity after the multi-products such as oxidation and photochemical decomposition in atmosphere.
