Problems solved by technology

[0007] In the past many years, the only iron-expelling agent available in China was deferoxamine. Because it cannot be absorbed orally and has a short half-life, it must be infused subcutaneously, 5-7 days a week, and each infusion lasts 8-12 hours , it is time-consuming and inconvenient to use, and there are many adverse reactions, resulting in poor long-term medication compliance of patients, which also limits their wide use

Embodiment 1

[0028] Embodiment 1 (prescription quantity is 1000 bags)

[0029] Raw material dosage (g)

[0030] Deerasirox 125

[0031] Lactose 590

[0032] Microcrystalline Cellulose 590

[0033] 10% PVP K30 aqueous solution 75

[0034] Crospovidone 75

[0035] Sodium Lauryl Sulfate 3

[0036] Aspartame 42

[0037] Preparation process: Weigh the prescribed amount of deferasirox, lactose, microcrystalline cellulose, crospovidone, sodium lauryl sulfate and aspartame, pass through a 80-100 mesh sieve and mix thoroughly. Add an appropriate amount of 10% PVP K30 aqueous solution and stir well to make a soft material. Extrude the soft material through a 24-mesh sieve to make wet granules, and dry at 60°C for 2 hours. The dried granules are passed through a 18-mesh sieve for granulation, quality inspection, and packaging (1.5g / bag) after passing the test.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and relates to a medicine for treating chronic iron overload diseases, in particular to a deferasirox granule and a preparation method thereof. Background technique [0002] Deferasirox is an orally active chelating agent that interacts with iron (Fe 3+ ) are highly selective. Developed by Novartis, it was first launched in the United States in 2005 under the trade name Exjade. It is mainly used for the treatment of chronic iron overload disease caused by blood transfusion at the age of 2 and above; the treatment of chronic iron overload in patients with non-transfusion-dependent thalassemia (NTDT) at the age of 10 and above. [0003] Patients with thalassemia require massive blood transfusions, and long-term blood transfusions may lead to iron overload. Chronic siderosis can cause damage to organs such as the heart, liver, and endocrine glands, and may be life-threatening in severe...
