Abstract
The invention discloses an injection, which takes oxcarbazepine as a major ingredient and is added with an inclusion agent, so that the injection is in the form of a homogeneous and stable colorless and transparent solution; the injection, after being preserved for a long time, is stable in character, and the content of active ingredients can reach 0.5-5%. In the case of emergency, for example patients are undergoing operations or some patients suffer from gastrointestinal diseases, the oxcarbazepine injection can be administrated timely when diseases attack in the patients who have trouble in taking drugs through oral administration.
Description
Technical field
The present invention relates to the preparing technical field of oxcarbazepine medicament, especially a kind of oxcarbazepine injection and preparation method thereof.
Background technology
Oxcarbazepine (10,11-dihydro-10-oxo-5H-dibenzo [b, f] azepine-5-carboxamide), white is to light yellow crystalline powder, and this product is antuepileptic, is the 10-ketone group derivant of carbamazepine, its drug effect is similar to carbamazepine, acts on identical or slightly strong, but its untoward reaction is few.There is the inhibitory action of high selectivity cerebral cortex layer motor region by this product, it is therefore prevented that the propagation of abnormal electric wave, epilepsy limitation or tonic clonic seizure and affective disorders is all had satisfied curative effect, trigeminal neuralgia also has good analgesic effect.For treating epilepsy limitation and tonic clonic seizure, can effectively improve the Vigilance of patient, identification and memory.Can be additionally used in anti-trigeminal neuralgia, the untoward reaction such as it is tired, movement disorder, impotence is less.
Oxcarbazepine is slightly molten in chloroform, slightly soluble in methanol, acetone and dichloromethane, almost insoluble in water, ethanol, 0.1mol/L hydrochloric acid or sodium hydroxide solution.Due to the indissoluble character of oxcarbazepine, the inclusion technique of cyclodextrin is utilized to improve oxcarbazepine dissolubility in water, in order to make injection.
Summary of the invention
It is an object of the invention in emergency situations, as patient in operation, some gastroenteropathys patient, morbidity time oral drugs have an obstacle, oxcarbazepine injection can drug treatment in time.
The technical solution used in the present invention is:
A kind of oxcarbazepine injection, it is characterised in that: every 100 milliliters comprise following components:
Oxcarbazepine 0.5-5g
Solubilizing agent 0.5-5g
And, described solubilizing agent is hydroxypropyl-beta-cyclodextrin, sulfoalkyl cyclodextrin, sulphur butyl-beta-cyclodextrin.Through investigating, when the ratio of oxcarbazepine and cyclodextrin is 1:1, effect is best.
The preparation method that it is a further object to provide a kind of oxcarbazepine injection, comprises the following steps:
Cyclodextrin is mixed with water for injection；
Above-mentioned solution adds oxcarbazepine；
Water for injection is settled to 100ml, prepares finished product after membrane filtration is degerming.
Advantages of the present invention and good effect: in the present invention, with oxcarbazepine for main component, add cyclodextrin, makes injection form the colourless transparent solution of isotropic stable, and after long-term storage, character is stable, easy to use, safety.
