specific Embodiment approach 1

[0020] Embodiment 1: Sodium creatine phosphate oral solid preparation of this embodiment is composed of 204-206g of sodium phosphate phosphate, 41-43g of starch, 27-29g of sodium starch glycolate, 59-61g of microcrystalline cellulose and 5 ~7g of absorption enhancer is made into sodium phosphate oral enteric-coated capsule; wherein the absorption enhancer is L-glutamine, sodium lactate, d-potassium hydrogen tartrate or vitamin B 1 .

specific Embodiment approach 2

[0021] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the sodium creatine phosphate oral solid preparation is composed of 205g of sodium creatine phosphate, 42g of starch, 28g of sodium starch glycolate, 60g of microcrystalline cellulose and 6g of The absorption enhancer is made into sodium phosphate creatine oral enteric-coated capsules. Others are the same as the first embodiment.

Abstract

The invention discloses a creatine phosphate sodium oral solid preparation and a preparation method thereof, relating to an oral solid preparation and a preparation method thereof. The invention solves the problem that the existing pharmaceutical factories can not produce the creatine phosphate sodium oral solid preparation at home and abroad. The creatine phosphate sodium oral solid preparation consists of creatine phosphate sodium, starch, carboxymethyl starch sodium, microcrystalline cellulose and absorbefacient. The method comprises the steps of: weighing raw materials, drying and screening, mixing and filling to obtain an enteric capsule. The creatine phosphate sodium oral solid preparation consists of creatine phosphate sodium, absorbefacient, microcrystalline cellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose solution, magnesium stearate, acrylic resin II, ethanol, twain-80, castor oil and phthalic acid diethyl ester. The method comprises the steps of: weighing raw materials, screening, preparing wet granule, tabletting, spraying casing liquid to obtain an enteric coated tablet. The invention realizes the preparation of the creatine phosphate sodium oral solid preparation, and can protect cardiac muscle and skeletal muscle.

Description

technical field [0001] The present invention relates to an oral solid preparation and a preparation method thereof. Background technique [0002] The worldwide pharmaceutical preparation of endogenous creatine phosphate is only a dosage form of sodium phosphate creatine powder injection, which is used in cardioplegia during cardiac surgery to protect the myocardium or to treat abnormal myocardial metabolism in ischemic conditions. Because the powder injection requires corresponding medical equipment and solvents, general places other than medical institutions do not have the conditions to use sodium creatine phosphate powder injection anytime and anywhere for injection, and the onset of myocardial disease is generally sudden, so the drug needs A pharmaceutical preparation that can be used directly orally anytime, anywhere. [0003] Exogenous phosphocreatine is distributed in skeletal muscle in addition to cardiac muscle. The current sodium creatine phosphate powder injecti...
