Embodiment 1

[0023] Plain Tablet Prescription:

[0024]

[0025] Coating Solution Prescription:

[0026] 3g

[0027] water 32g

[0028] Preparation:

[0029] ① Grind the prescribed amount of Apremilast and pass through a 250-mesh sieve; respectively pass through a 80-mesh sieve for lactose, microcrystalline cellulose, croscarmellose sodium, and micropowder silica gel;

[0030] ②Mix the above-mentioned Apremilast with lactose, microcrystalline cellulose, croscarmellose sodium, and micropowder silica gel for 20 minutes;

[0031] ③Transfer the uniformly mixed medicinal powder to a powder feeder and press into tablets;

[0032] ④The prescription amount It is dissolved in water and made into a solution of about 9% as a film coating solution to coat the drug-containing tablet core. During the coating process, the temperature of the material is controlled at 40°C to 42°C. After the process is completed, the weight of the tablet core increases by about 3%.

Abstract

The invention provides an apremilast solid composition. The apremilast solid composition is prepared by the following components in parts by weight: 5% to 14% of apremilast; 82% to 90% of a filler; 1%to 1.5% of a disintegrant; 0.5% to 1% of a lubricant; and 2% to 6% of a coating material. The apremila solid composition prepared by the invention has a dissolution rate of more than 95%, has high bioavailability, and stable and reliable quality, and has wide clinical application prospects.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and in particular relates to a solid composition of apremilast with high dissolution rate and stable quality and a preparation method thereof. Background technique [0002] Psoriatic arthritis (PsA) is an inflammatory joint disease associated with psoriasis, with a psoriatic rash that causes pain, swelling, tenderness, stiffness, and dyskinesia in joints and surrounding soft tissues. There are sacroiliitis and / or spondylitis, the course of the disease is protracted, easy to relapse, and the joints may be ankylosing in the late stage, resulting in disability. In about 75% of PsA patients, the rash appeared before arthritis, in about 15% of those who appeared at the same time, and in about 10% of patients with rash after arthritis. [0003] This disease often has the tendency of family aggregation, the prevalence rate of first-degree family members is as high as 30%, and the risk of monozygotic ...
