[0002] With the accelerated pace of modern life and the complex changes in environmental factors, the incidence of nasal diseases such as rhinitis and sinusitis has been increasing year by year. These diseases not only bring physical discomfort to patients, such as nasal congestion, runny nose, sneezing, etc., but may also cause a series of complications such as headaches, dizziness, memory loss, etc., seriously affecting the quality of life and work efficiency of patients. At present, there are many kinds of drugs on the market for the treatment of nasal diseases, but most of them have certain limitations, such as antibiotics are prone to drug resistance, and long-term use of hormone drugs may cause side effects. Therefore, the development of a safe, effective and low-side effect drug for the treatment of nasal diseases has important clinical significance and social value.

[0003] Vitamin C, as a common nutrient, has a variety of physiological functions that are beneficial to the human body. It is a powerful antioxidant that can remove free radicals in the body and enhance the body's immunity; at the same time, vitamin C is also involved in the synthesis of collagen, which helps to maintain the integrity of the nasal mucosa and promote the repair of damaged mucosa. In addition, vitamin C also has a certain anti-inflammatory effect and can reduce the inflammatory response of the nasal mucosa. Based on the above theoretical basis, the present invention proposes a nasal drop with vitamin C as the main ingredient, aiming to provide a new, safer and more effective solution for the treatment of nasal diseases. Summary of the invention

[0033] Figure 2 The present invention discloses a method for preparing vitamin C nasal drops for removing latent pathogens. DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] See also Figure 1 As shown, a vitamin C nasal drop for removing latent pathogens comprises the following components: vitamin C, with a mass concentration of 20% to 40%; an osmotic pressure regulator, with a mass concentration of 0.5% to 5%; an antibacterial agent, with a mass concentration of 0.01% to 0.05%; a moisturizer, with a mass concentration of 1% to 3%; a stabilizer, with a mass concentration of 0.01% to 0.5%; a preservative, with a mass concentration of 0.01% to 0.5%; a pH regulator; and a purified water solvent.

[0037] As can be seen from the above, vitamin C nasal drops are composed of vitamin C, osmotic pressure regulators, antibacterial agents, moisturizers, stabilizers, preservatives, pH regulators and purified water solvents. Vitamin C has multiple physiological functions such as anti-oxidation, enhancing immunity, anti-inflammatory and promoting mucosal repair. It can comprehensively treat nasal diseases from multiple aspects, can significantly reduce the patient's nasal mucosal inflammation, help restore the integrity of mucosal epithelial cells, significantly improve nasal ventilation function, and effectively relieve symptoms such as nasal congestion, runny nose, sneezing, etc. The use of this nasal drop can stimulate the metabolism of the nasal cavity, and the nasal drop can acidify the infected mucosa and eliminate bacteria. The nasal drop waste liquid and infected mucosa are discharged together through secretions such as nasal mucus, and the bacteria inside the nasal cavity are discharged to form a nasal environment with few bacteria and safety. In addition, the antibacterial performance of the nasal drops is enhanced by antibacterial agents. At normal dosages, no obvious side effects will be produced, and no irritation or damage will be caused to the nasal mucosa. It can be used for a long time, and is especially suitable for special populations such as children, pregnant women and the elderly, and has a high safety of use.

[0038] Vitamin C is the core ingredient of this formula, and its content is determined based on a comprehensive consideration of the absorption capacity of the nasal mucosa and the therapeutic effect. When the concentration of vitamin C is within the above range, an effective drug concentration gradient can be formed on the surface of the nasal mucosa, stimulating nasal metabolism with a higher concentration of vitamin C. At the same time, the vitamin C solution can acidify the infected mucosa and dissolve the waste liquid and discharge it from the nasal cavity in the form of nasal mucus, thereby reducing the number of pathogens inside the nasal cavity and thereby improving the healing effect of nasal diseases. Different from traditional bactericidal and antibacterial methods, it can effectively avoid drug resistance problems. Even if too much vitamin C is absorbed by the human body, it will be excreted from the body through urine. Compared with oral vitamin C, the topical treatment effect is more prominent, which can significantly enhance the immunity of the nasal mucosa, strengthen the natural defense function of the respiratory tract, relieve nasal dryness and discomfort, and improve respiratory health.

[0039] Antibacterial agents can increase the bactericidal effect of the nasal drop system and effectively remove latent pathogens inside the nasal cavity. Moisturizers can keep the nasal cavity moist, prevent the nasal cavity from drying out, and effectively maintain the protective effect of the nasal mucosa. Stabilizers can prevent the oxidation of vitamin C in the nasal drops. Preservatives can prevent microbial contamination of the nasal drops. Osmotic pressure regulators make the osmotic pressure of the nasal drops match the physiological osmotic pressure of the human nasal mucosa, reduce the irritation of the nasal drops to the nasal mucosa, and improve the patient's comfort. pH regulators are used to adjust the pH value of the nasal drops to close to the normal pH value of the human nasal mucosa, which is beneficial to the stability of vitamin C and the absorption of drugs by the nasal mucosa.

[0045] In order to expand the audience of nasal drops, the mass concentration of vitamin C is adjusted to 25% to 33%, which can not only ensure that the vitamin C in the nasal drops still has a high concentration to work at room temperature, but also effectively avoid the precipitation phenomenon caused by excessive concentration of vitamin C in the nasal drops.

[0046] The mass concentration of the osmotic pressure regulator is 1% to 3%, and the osmotic pressure regulator includes sodium chloride and glucose, the antibacterial agent includes benzalkonium chloride, the humectant includes glycerol, the mass concentration of the stabilizer is 0.05% to 0.2%, and the stabilizer includes disodium EDTA, the mass concentration of the preservative is 0.05% to 0.2%, and the preservative includes benzoic acid, sorbic acid and parabens, the pH adjuster includes phosphate buffer and acetate buffer, and the added amount is an amount for adjusting the pH value of the nasal drop system to 5.5 to 7.5.
