Example Embodiment

[0032] Example 1

[0033] Naproxen 420g

[0034] Lactose monohydrate 60g

[0035] Microcrystalline cellulose 60g

[0036] Crospovidone 24g

[0037] Hypromellose 30g

[0038] Magnesium stearate 6g

[0039] The preparation method is as follows:

[0040] 1) Pass the naproxen raw material through a 120-mesh sieve; the remaining auxiliary materials pass through an 80-mesh sieve;

[0041] 2) Preparation of the adhesive: According to the ratio of the mass of the adhesive to the volume of purified water at a ratio of 6:100, a 6% solution is prepared and placed on the constant temperature heating stirrer 6 to continue stirring;

[0042] 3) Weigh the processed naproxen, lactose, and microcrystalline cellulose according to the prescribed amount, and weigh and mix crospovidone according to 50% of the prescribed amount;

[0043] 4) Open the fluidized bed program, lock the air valve 12 of the sealed chamber, start the fan, and suck the mixed raw and auxiliary materials into the fluidized bed through the va...

Example Embodiment

[0050] Example 2

[0051] Naproxen 480g

[0052] Starch 48g

[0053] Croscarmellose Sodium 15g

[0054] Sodium Carboxymethyl Starch 15g

[0055] Hydroxypropyl cellulose 36g

[0056] Magnesium stearate 6g

[0057] Refer to Example 1 for the operation process, and the differences are as follows:

[0058] 1) Pass the naproxen raw material through a 120-mesh sieve; the remaining auxiliary materials pass through an 80-mesh sieve;

[0059] 2) Preparation of the adhesive: a 5% solution is prepared according to the ratio of the mass of the adhesive to the volume of purified water of 5:100;

[0060] 3) Weigh and mix the processed naproxen, starch, and sodium carboxymethyl starch according to the prescribed amount;

[0061] 4) The mixed raw and auxiliary materials are sucked into the fluidized bed, and the adhesive is sprayed into the top spray to granulate. The parameters are as follows:

[0062] Air volume (m 3 / h): 70-80

[0063] Atomization pressure (kg / cm 2 ): 1.3-1.5

[0064] Inlet air temperature (...

Abstract

The invention discloses a preparation method of a medicine composition containing naproxen and relates to the field of pharmacy. According to a prescription, the medicine composition is composed of naproxen raw material medicine and medicinal auxiliary materials such as a diluting agent, a disintegrating agent, adhesive and a lubricating agent, through a method that spraying granulating is carried out on a fluidized bed, the three procedures of mixing, granulating and drying in a traditional technology are completed at a time, in this way, production efficiency is improved, and produced particles are even in particle size and good in flowability and compression forming; the particles produced through the fluidized bed are pressed into tablets, and therefore compared with a wet-method granulating technology, the medicine dissolution rate of the tablets is obviously increased.

Description

technical field [0001] The invention relates to the field of pharmacy, discloses a pharmaceutical composition containing naproxen, and also discloses a fluidized-bed production method of direct-pressing granules of naproxen. Background technique [0002] Naproxen is a non-steroidal anti-inflammatory analgesic, which has strong antipyretic, analgesic and anti-inflammatory effects, and can inhibit the synthesis of prostaglandins to exert anti-inflammatory and analgesic effects. It is clinically applicable to the treatment of fever and pain caused by various reasons. It is often used to treat rheumatism and rheumatoid arthritis, gastric arthritis, ankylosing spondylitis, gout, arthritis, tenosynovitis and other diseases. It can also be used to relieve muscle pain. Pain from bone sprains, bruises, injuries, and dysmenorrhea. The peak plasma concentration is reached 15 minutes after intravenous injection, and the half-life is 12-14 hours. Its notable feature is its low toxicity...
