The preparation also includes a film-coating system containing a film-forming polymer, plasticizer, and coloring agent, along with tablet-forming excipients such as preservatives, fillers, stabilizers, and anti-caking agents in appropriate proportions to create a highly stable film-coated tablet.The preparation according to the invention has the advantages of preserving the active ingredients of the medicinal herbs, increasing stability, improving bioavailability, being convenient to use, and contributing to enhancing the effectiveness of supporting the treatment of symptoms of allergic rhinitis and sinusitis. It is also safe for long-term use because the preparation contains herbal extracts of natural origin that have been used for a long time in traditional medicine, and does not contain synthetic vasoconstrictors, corticosteroids, or antibiotics. In addition, the extraction and purification process helps remove impurities and reduce irritating components, thereby limiting the risk of unwanted side effects with prolonged use.
