Abstract

The present invention belongs to the field of medicine technology, and is especially oral loratadine disintegrating tablet for treating allergic diseases and its preparation process. The oral loratadine disintegrating tablet includes loratadine as effective medicine component, and excipient mixture comprising disintegrating agent, stuffing, soluble polyol and penetrant. The oral loratadine disintegrating tablet consists of loratadine 20-50 wt%, disintegrating agent 5-15 wt%, stuffing 10-30 wt%, soluble polyol 30-60 wt%, and penetrant 1-5 wt%. The oral loratadine disintegrating tablet, after being disintegrated fast, can cover gastrointestinal mucous membrane widely, and has fast acting, no first pass effect, high bioavailability, and convenient taking.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a loratadine orally disintegrating tablet for treating allergic diseases and a preparation method thereof. Background technique [0002] Anaphylaxis is an acute, systemic, severe and even life-threatening allergic reaction that occurs when a patient is exposed to the same allergen again after being previously sensitized by an allergen. Symptoms of an allergic reaction can appear immediately or within 2 hours of exposure to an allergen.
