Description

Technical Field

[0001] The utility model relates to the technical field of drug solution production filtration, in particular to a filtration structure for the production of furosemide oral solution. Background Art

[0002] Furosemide oral solution is an oral drug whose main ingredient is furosemide. Furosemide is a type of diuretic and is commonly used to treat hypertension, edema and other diseases. When producing furosemide oral solution, it is necessary to mix furosemide and other drugs with the required auxiliary materials in a certain proportion, add a certain amount of water to dissolve them, and then filter the liquid formed after the drug and auxiliary materials are mixed to remove impurities and microorganisms. Subsequently, the filtered solution is sterilized by high temperature and high pressure or ultraviolet radiation to ensure the sterility of the product. Finally, quality inspection is carried out for final packaging. However, the existing filtration structure for the production of furosemide oral solution adopts a direct pouring method to add the furosemide oral solution into the filtration mechanism. This method will result in too fast a filtration speed, and too fast a filtration speed may prevent the drug from fully passing through the filter or interacting with the filter medium unnecessarily, resulting in part of the drug being retained in the filter and unable to be collected, affecting the quality of the drug.

[0003] In view of the above problems, a filtering structure for producing furosemide oral solution is proposed. Utility Model Content
