Problems solved by technology

[0004] Due to the incomplete development of various body organs of young children, when taking tablet medicines, due to the poor swallowing ability of children, it is very easy for the accidents that the tablets block the trachea or get stuck in the throat.
Most parents use the method of pressing the pills into powder and then adding water to take them. However, since most medicines have obvious bitter taste, it is rare for children to take them voluntarily. Most parents use the method of forced feeding. This method is very likely to cause the child's tracheal blockage and cause danger.
Although the syrup solves the problem of taking compliance, the preservatives in it also cause harm to children's bodies

Abstract

The invention relates to a desloratadine grain and a preparation method thereof. The preparation method comprises the steps: fully coating a medicine and proper auxiliary materials (such as a stabilizing agent, a cosolvent, a PH adjusting agent, a filling agent and the like) into a water-soluble high molecular material; and adding a proper opacifier into a coating material, so that the medicine can be isolated from the light and the external moist air when the medicine is stored, and the stability of the medicine can be adequately guaranteed when the medicine is stored under the room temperature; mixing the coated grain with a proper flavoring agent and soluble auxiliary materials to obtain the desloratadine granular formulation; and properly adding a small quantity of edible coloring agent and fruity essence to increase the novelty to the children, and improve the taking compliance.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a desloratadine granule and a preparation method thereof. Background technique [0002] Desloratadine is a non-sedating long-acting tricyclic antihistamine, which is the active metabolite of loratadine, and can inhibit various allergic inflammatory processes by selectively blocking peripheral H1 receptors. Chemical release. The main scope of treatment includes relief of symptoms of allergic rhinitis or chronic idiopathic urticaria. [0003] The dosage forms available for clinical selection mainly include tablets, dispersible tablets, and syrups. The absorption of tablets in the body must go through processes such as disintegration and dissolution before reaching the blood circulation through the gastrointestinal tract. However, during the production process of tablets, it is often difficult to disintegrate due to reasons such as dressings and processes, and the drug release is not compl...
