Technical Field
The invention relates to a betahistine hydrochloride soft capsule and a preparation method thereof.
Background
Betahistine hydrochloride is a diamine oxidase inhibitor. Has obvious dilating effect on cerebral blood vessels and cardiovascular blood vessels, especially on the vertebral bottom artery system, obviously increases blood flow of heart, brain and peripheral circulation, improves blood circulation, reduces systemic blood pressure, can increase blood flow of cochlea and anterior floor, thereby eliminating auditory vertigo, tinnitus and auditory occlusion, increasing capillary permeability, promoting absorption of extracellular fluid, eliminating intralymphatic edema, resisting vasoconstriction of catecholamine and reducing arterial pressure, inhibiting plasma coagulation and platelet aggregation induced by ADP, prolonging thrombosis formation time in vitro of white rats, and has slight diuretic effect. The traditional Chinese medicine composition is mainly used for Meniere's syndrome, vascular headache and cerebral arteriosclerosis in clinic, and can be used for treating acute ischemic cerebrovascular diseases, such as cerebral thrombosis, cerebral embolism, transient cerebral circulation insufficiency and the like, and also has the effect of upright vertigo, tinnitus and the like caused by hypertension.
Since the betahistine hydrochloride comes into the market, the betahistine hydrochloride is valued and popular by medical workers and patients due to the definite curative effect and less toxic and side effects, but because of the strong hygroscopicity, the betahistine hydrochloride is difficult to prepare into oral solid preparations, the clinical common use is basically limited to oral solutions and injections (including powder injections and transfusions), and because the cost is high and the carrying and the taking are inconvenient, especially for old patients, the wide application of the betahistine hydrochloride is limited.
