Abstract

The invention discloses a stable triprolidine hydrochloride-containing oral solution agent and a preparation method thereof, and belongs to the field of medicine preparations. The oral solution is used for treating diseases such as allergy, common cold and rhinitis. The triprolidine hydrochloride-containing oral solution preparation has the advantages that the medicine use safety is higher; the bitter taste is reduced; the stable triprolidine hydrochloride-containing oral solution agent is particularly suitable for children to use. The oral solution preparation has the pH being 4 to 7, so thatthe stability of the preparation is higher.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to an oral solution preparation containing triprolidine. Background technique [0002] Allergic diseases are generally characterized by immediate allergic reactions, also known as type I allergic reactions, which mainly cause allergic rhinitis, asthma, conjunctivitis, eczema, food allergies, drug allergies, and severe allergic reactions. In the past few decades, the incidence of allergic diseases has increased significantly, which has seriously affected the quality of life of children and adults, and even endangered their lives. It has become a public health issue of global concern. [0003] Immunoglobulin E (IgE) is an antibody that mediates type I allergic reactions. There are two types of IgE receptors in the human body: the high-affinity receptor FcεRI and the low-affinity receptor FcεRII, the former expressed in mast cells and basophils, the latter expressed in B cel...
