Embodiment 1

[0027] Based on 1000 pidotimod capsules, crush pidotimod, starch, and low-substituted hydroxypropyl cellulose through a 100-mesh sieve, weigh 400 g of pidotimod, 3 g of starch, and 7 g of low-substituted hydroxypropyl cellulose, Mix evenly according to the principle of equal increase, add an appropriate amount of soft material made of starch slurry, use a 60-mesh sieve to make granules, dry at 60°C for 2-3 hours, granulate, and pack into capsules. Each capsule contains 400mg of pidotimod.

Embodiment 2

[0029] Based on 1000 pidotimod capsules, crush pidotimod, starch and sodium carboxymethyl starch through a 100-mesh sieve, weigh 200g of pidotimod, 82g of starch, and 15g of sodium carboxymethyl starch, and press etc. The principle of increasing the amount is to mix evenly, add an appropriate amount of sodium carboxymethyl starch solution to make soft materials, use a 24-mesh sieve to make granules, dry at 60°C for 4 hours, pass through a 24-mesh sieve for granulation, add 3g of magnesium stearate, and mix evenly. Packed in capsules, each capsule contains 200mg of pidotimod.

Embodiment 3

[0031] Based on 1000 pidotimod capsules, crush pidotimod, starch, microcrystalline cellulose, and low-substituted hydroxypropyl cellulose through a 100-mesh sieve, weigh 200 g of pidotimod, 52 g of starch, and microcrystalline cellulose 30g of cellulose, 15g of low-substituted hydroxypropyl cellulose, mix evenly according to the principle of equal increase, add appropriate amount of starch slurry to make soft material, sieve with 24 mesh to make granules, dry at 60°C for 2 to 3 hours, and pass through a 24 mesh sieve granules, add 3g of magnesium stearate, mix evenly, pack into capsules, each capsule contains 200mg of pidotimod.

Abstract

The invention provides Pidotimod capsule preparation comprising major medical component Pidotimod and pharmaceutically acceptable medical auxiliary material, which is capsule. Chemical name of the major medical component Pidotimod is: (R)-3-((S)- (5-oxo-2-pyrrolidyl)-carbonyl)-tetrahydro-thiazole-4-carboxylic acid. The capsule overcomes the disadvantages of other dosage forms of the Pidotimod, and has the functions of photophobism and dampproof ability; the capsule can also conceal poor smell of the medicine, prevent and slow down decomposition and improve stability of the medicine so as to ensure that curative effects of the medicine can be better displayed; moreover, the dosage of the capsule can be easily disintegrated, with rapid absorption, high bioavailability and convenient clinical application compared with dosage forms such as tablet preparation, etc.
