The application discloses irbesartan and hydrochlorothiazide tablets and a preparation method thereof. The tablet comprises irbesartan granules and hydrochlorothiazide granules. The irbesartan granules comprise irbesartan, hydroxyphenyl cellulose, glycerophosphoric acid calcium, a disintegrant and a binder. The hydrochlorothiazide granules comprise hydrochlorothiazide, a diluent, a disintegrant and a binder. The tablet can solve the problems of easy agglomeration of irbesartan and hydrochlorothiazide, and difficulty in controlling the content uniformity due to the great difference in the dosage. Meanwhile, the tablet can effectively overcome the poor solubility of irbesartan and hydrochlorothiazide, and good dissolution effect is obtained.

This invention belongs to the field of bone repair materials technology, specifically relating to a bone repair implant based on a cold-cured resin-calcium glycerophosphate composite gel and its preparation method. The bone repair implant of this invention uses cold-cured resin as the main component of the gel, hyaluronic acid as an auxiliary component, and calcium glycerophosphate, citrate, calcium gluconate, and calcium amino acid as gel solidification promoters to form a bone repair implant with high elasticity, high toughness, and a certain strength. It has been proven that this implant can be used as a basic material for cartilage tissue repair, providing an effective option for the repair of articular cartilage and other cartilage tissues.

The invention relates to dentistry, and more particularly to a novel agent in the form of a gel for the treatment and / or prophylaxis of conditions characterized by loss of minerals and salts front tooth enamel. The claimed agent, provided in gel foam, for the treatment and / or prophylaxis of conditions characterized by loss of minerals and salts from tooth enamel contains the following ingredients: 19 wt % glycerin, 10 wt % xylitol 2.3 wt % hydroxyethyl cellulose, 0.09 wt % guar gum, 1.5 wt % calcium glycerophosphate, 0.12 wt % magnesium chloride, 0.9 wt % non-ionic surfactant, 0.24 wt % preservative, 0.04 wt % flavouring agent, she remainder water. The claimed agent provides effective treatment and prophylaxis of the demineralization / hypomineralization of dental tissue, mild forms of fluorosis, and the adverse consequences thereof.

The invention discloses a novel synthesis method of calcium glycerophosphate. The method comprises the following steps: reacting glycidol with a sodium dihydrogen phosphate aqueous solution under an acidic condition to generate an intermediate sodium glycerophosphate, then generating disodium glycerophosphate under an alkaline condition, and finally carrying out a replacement reaction with calcium chloride to obtain a high-purity calcium glycerophosphate product. The process is high in atom economy and small in environmental pollution, the product purity can reach 99.0% or above, and the method is suitable for the fields of medicine, food, feed additives and the like.

The invention provides a preparation method and application of a nano-particle micro-arc oxidation coating on the surface of a medical magnesium alloy. The preparation method comprises the following steps: preparing an electrolyte, wherein the electrolyte comprises the following components: calcium glycerophosphate, sodium hexametaphosphate, potassium hydroxide, ammonium bifluoride, glycerol, hydrogen peroxide, Nano-SiO2 and nano-hydroxyapatite; sequentially adding the components into ultrapure water, and stirring to uniformly mix; a bipolar current mode power supply is used for MAO processing. The coating obtained based on the method has good biological activity and corrosion resistance at the same time, the coating has good stability in a body fluid environment, and the degradation time is prolonged so as to be matched with the bone healing rate.

The invention discloses a preparation method of glycerophosphate, and belongs to the field of pharmaceutical and chemical engineering technologies and food nutrition fortifiers. The preparation method comprises the following steps: (1) adding glycidol and a phosphating agent into a solvent for reaction, and treating after the reaction is finished to obtain a glycerophosphate solution; and (2) adding a metal oxide into the glycerophosphate solution obtained in the step (1), carrying out a stirring reaction, filtering after the reaction is finished, adding ethanol into the obtained filtrate, crystallizing, filtering and washing to obtain calcium glycerophosphate. According to the method, the adopted raw materials are simple and easy to obtain, excessive protection is not needed in the reaction process, the reaction route is short, the reaction is single and environmentally friendly, and the product yield is high.
