Problems solved by technology

[0005] Fluticasone Propionate Nasal Spray produced by Glaxo, due to the large volume of the spray bottle, the small volume of liquid medicine (4.0ml) only exists at the bottom of the spray bottle, the liquid level is low, and the depth of the immersion pipette is not enough , resulting in incomplete absorption of the liquid medicine, resulting in less effective spraying times, more residues, and large waste. Although the defect of insufficient effective spraying times can be solved by increasing the filling volume of the liquid medicine, it further increases the cost of expensive liquid medicine. The waste of medicines leads to high drug prices and increases the economic burden of patients

Abstract

The invention provides a fluticasone propionate nasal spray. A used spraying device comprises a spray bottle and a spray nozzle, and is characterized in that the spray bottle comprises an outer casing (1) and a liner (2) with a volume of 5.0 ml, wherein the shape of the liner of the spray bottle adopts a cylinder plus an eggplant shape or a cylinder plus a sphere and an another cylinder with a smaller diameter; the outer casing of the spray bottle is provided with a shape, a size and an interface part which are the same as those of a conventional 10 ml spray device sold on the market; and the spray nozzle adopts a spray nozzle of the conventional 10 ml spray device sold on the market. The fluticasone propionate nasal spray has the advantages that the residue is small, the security is high, and the fluticasone propionate nasal spray can be effectively sprayed for a plurality of times; and the production cost can be reduced, and medicine waste is completely prevented.

Description

Technical field: [0001] The invention relates to a fluticasone propionate nasal spray, in particular to a fluticasone propionate nasal spray using a spray bottle with a volume of 5.0ml of an inner container. Background technique: [0002] Fluticasone propionate is a glucocorticoid. Compared with similar drugs, it has the following characteristics: 1. It is highly fat-soluble and easily penetrates cell membranes. Compared with beclomethasone dipropionate and budesonide, fluticasone propionate has the fastest binding time to glucocorticoid receptors and the slowest dissociation; 2. It has high selectivity and high affinity for glucocorticoid receptors; 3. The anti-inflammatory effect is stronger than that of beclomethasone dipropionate and budesonide; 4. The bioavailability after oral administration is lower than 1%, and the systemic absorption is almost completely inactivated after liver metabolism; 5. The hypothalamus-pituitary-adrenal gland ( HPA) has a small inhibitory ef...
