Embodiment 1

[0043] prescription

[0044]

[0045] The preparation method is to crush all the components in the prescription except sodium carbosulfonate into fine powder with a fineness of more than 100 mesh; dry the starch at 100-105°C to keep the water content below 8%; Sodium sulfonate and dry starch are mixed, pulverized, and passed through an 80-mesh sieve; then mixed with prescription quantities of mannitol, microcrystalline cellulose, hydroxypropyl methylcellulose and menthol and 1 / 2 prescription quantities of crospovidone Mix and pass through a 80-mesh sieve; then add an appropriate amount of ethanol water solution with a volume fraction of 60% to make soft materials, granulate with a 24-mesh sieve, dry at 60±5°C, pass the dry granules through a 24-mesh sieve for granulation; then add the remaining Crospovidone and the prescribed amount of magnesium stearate were mixed evenly and tabletted to make 1000 orally disintegrating tablets of sodium carbosulfonate, each containing 10 ...

Abstract

The invention discloses carbazochrome sodium sulfonate oral disintegrating tablets and a preparation method thereof. The carbazochrome sodium sulfonate oral disintegrating tablets are prepared from the following components in percentage by mass: 1-15% of carbazochrome sodium sulfonate, 50-90% of filler, 5-40% of disintegrant, 1-8% of adhesive, 0.1-5% of lubricant and 0.1-5% of flavoring agent. The oral disintegrating tablets have the advantages of smooth surface, attractive appearance, moderate hardness, quick absorption, quick effect taking, small liver first-pass effect, high bioavailability, little irritation to the gastrointestinal tract, favorable mouthfeel and convenient taking, can quickly disintegrate in the oral cavity without water, is particularly suitable for aged people, children, patients in bed or with dysphagia, and especially for bleeding patients inconvenient to drink water during or after operations. The oral disintegrating tablets are prepared in a wet-method pelletizing tabletting way. The preparation method has the advantages of simple production technology, stable and easily-controlled preparation quality, and low cost, and is suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to a pharmaceutical preparation, in particular to an orally disintegrating tablet of sodium carbosulfonate, and also relates to a preparation method of the orally disintegrating tablet. Background technique [0002] Tablet has the advantages of stable quality, accurate dosage, convenient taking and carrying, high degree of production mechanization, and low production cost. It is one of the most commonly used pharmaceutical dosage forms at present. But at the same time, due to its slow disintegration, low bioavailability, and difficulty in swallowing for some patients, its application is limited to a certain extent. In recent years, new types of tablets such as orally disintegrating tablets, dispersible tablets and sublingual tablets have emerged. Orally disintegrating tablet is a tablet that can disintegrate or dissolve quickly without water in the oral cavity. Convenient and other advantages, especially suitable for the elderly...
