Embodiment 1

[0028]

[0029]

[0030] The preparation method is:

[0031] (1) Desloratadine citrate, ascorbic acid, calcium hydrogen phosphate, microcrystalline cellulose and pregelatinized starch are taken by weighing the prescription amount, sieved and premixed with 60 meshes;

[0032] (2) Weigh the PVP k30 of the prescribed amount, add the prescribed amount of purified water to prepare a binder solution, and add it to the mixture prepared in step (1), granulate with a 30-mesh sieve, and dry in a fluidized bed until the moisture content is ≤5.0%. After sizing through a 24-mesh sieve, add silicon dioxide for total mixing to obtain desloratadine citrate granules;

[0033] (3) Fill the desloratadine citrate granules into gelatin hollow capsules (No. 3) to prepare 1000 desloratadine citrate capsules.

Embodiment 2

[0035] Name of raw material Prescription amount desloratadine citrate 8.8g Calcium hydrogen phosphate 45g microcrystalline cellulose 65g silica 1.2g Povidone (PVPk30) 1.5g ascorbic acid 1g purified water 20g

[0036] The preparation method is:

[0037] (1) take desloratadine citrate, ascorbic acid, calcium hydrogen phosphate and microcrystalline cellulose of prescription quantity, 60 mesh sieve, premix;

Abstract

The invention provides desloratadine citrate disodium capsules as well as a preparation method and application thereof. The capsules are composed of desloratadine citrate disodium particles and hollowcapsules, and the desloratadine citrate disodium particles contain desloratadine citrate disodium, ascorbic acid, a filler, a lubricant and an adhesive in a weight percentage ratio of (5-12):(1-3):(80-150):(0.5-2):(0.5-3). The invention also provides a preparation method of the desloratadine citrate disodium capsules and application of the capsules in preparation of medicines for treating rhinitis and urticaria. The desloratadine citrate disodium capsules disclosed by the invention are reasonable in formula and simple and convenient in production process; and by adding the ascorbic acid component, the dissolution rate and the stability of the desloratadine citrate disodium capsules are remarkably improved.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to desloratadine citrate capsules and a preparation method and application thereof. Background technique [0002] Desloratadine (Desloratadine) is a non-sedative long-acting tricyclic antihistamine and an active metabolite of loratadine, which can relieve seasonal allergic rhinitis by selectively antagonizing peripheral H1 receptors or associated symptoms of chronic idiopathic urticaria. In addition, in vitro studies showed that desloratadine inhibited the release of histamine from human mast cells. Animal studies suggest that desloratadine does not readily cross the blood-brain barrier. However, due to the well-known instability and low water solubility of desloratadine, it encounters great difficulties in preparation, and many documents have reported different solutions. For example, US2002 / 123504, WO2006 / 020534, CN1246794, etc. [0003] Also for example, CN201410104...
