Abstract

The invention relates to an loratadine oral dispersible film agent. The loratadine oral dispersible film agent is prepared from the following raw and auxiliary materials in percentage by mass of 25-40% of loratadine, 0.3-1% of polysorbate 80, 1-10% of plasticizer, 0.001-0.02% of glyceride fatty acid, 2-5% of povidone K30, 22-35% of hypromellose-E5, 10-25% of hydroxypropyl cellulose-SL, 1-8% of maltose, 0.5-5% of saccharin sodium, and 1-6% of opacifier; and the particle size X90 of loratadine is less than or equal to 10 mu m. The preparation process disclosed by the invention is simple and controllable, and is suitable for industrial mass production; the prepared oral dispersible film agent has significantly improved tensile strength, disintegration speed, taste and stability, has the advantages of high drug loading capacity, small volume, convenience in carrying, dosage control and administration, and rapid disintegration in the oral cavity without drinking water, realizes rapid release of active ingredients of the drug, has good taste and is easy to accept, and compliance and the safety of children medication are improved.

Description

technical field [0001] The invention belongs to the technical field of medicines and preparation methods thereof, and in particular relates to a loratadine orodispersible film and a preparation method thereof. Background technique [0002] Loratadine is an antihistamine. For the relief of symptoms associated with allergic rhinitis such as sneezing, runny nose, nasal itching, nasal congestion, and itching and burning of the eyes. Nasal and ocular symptoms and signs were rapidly relieved after oral administration of the drug. It is also suitable for the relief of symptoms and signs of chronic urticaria, pruritic skin diseases and other allergic skin diseases. Studies have shown that in Asian adults suffer from allergic rhinitis up to 30%, the highest prevalence rate in children is as high as 46%. [0003] At present, a number of loratadine oral preparations (common tablets, capsules, syrups, orally disintegrating tablets and orally dissolving tablets, etc.) have been listed...
