Problems solved by technology

However, the small crystals of mannitol may block the filter screen of the infusion tube, making the flow of the liquid unsmooth, and the concentration of the mannitol transmission liquid after the crystals are filtered is reduced, and the drug effect is reduced
In short, the easy crystallization of mannitol injection has caused a lot of inconvenience to its clinical application.
[0003] When using mannitol injection, when crystals appear, medical staff usually use traditional hot water baths, electric heating platens, electrified warm liquid bags, steam and other heating and dissolving methods to completely dissolve the crystals before use. A lot of inconvenience, especially for critically ill patients to delay the rescue time

Abstract

The invention relates to the technical field of medicinal preparations, in particular to a mannitol injection. The mannitol injection is prepared from the following raw materials in percentage by weight: 12 to 19 percent of mannitol, 0.5 to 1.3 percent of a jasmine extract, 0.8 to 1.6 percent of a pseudo-ginseng extract, and the balance of injection water, and the total percent is 100. Compared with the prior art, the mannitol injection provided by the invention has a good treatment effect and a good effect on treating high intracranial pressure caused by cerebral hemorrhage, does not crystallize at a low temperature, and is high in use safety and convenient to use clinically; hypersensitivity is avoided; adverse reactions, such as an infusion reaction, are remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a mannitol injection. Background technique [0002] Mannitol is a kind of hexanehexol, which is an isomer of sorbitol. It is a good diuretic and dehydrating drug. It is used to treat cerebral edema and increased intracranial pressure caused by various reasons. It is also used in other eye-reducing diseases. When internal pressure medicine is ineffective or before intraocular surgery. At 20°C, the solubility of mannitol in water is 1:5.5 (18%), and 20% mannitol injection is a supersaturated solution. When the room temperature is lower than 15°C, mannitol particles are easily produced, and even crystals are precipitated. When the temperature continues to drop, the crystals increase in size and become large columnar and flocculent crystals. If the packaging is a plastic soft bag, it will cause damage and increase the risk of medication. The particles in the man...
