The purpose of this invention is to provide a kind of effective percentage height, toxicity is low, and side effect is little, has certain safety and treats migrainous medicine.
Main caffeine, propranolol hydrochloride, the phenytoin Sodium of containing of the present invention is the 90.0-110.0% of labelled amount.
Its prescription: caffeine 60-100mg
Propranolol hydrochloride 8-15mg
Phenytoin Sodium 80-150mg
20% starch slurry 30-55mg
Magnesium stearate 5-10mg
Make 1
Preparation method: adopt the caffeine that meets " Chinese Pharmacopoeia " 8 or five years version regulations, propranolol hydrochloride, phenytoin Sodium take by weighing supplementary material successively, sieve respectively, mix homogeneously is made soft material with 20% starch slurry as binding agent, granulates by 10 nylon mesh, oven dry is 4-6 hour below 60 degree Celsius, natural cooling by 14 mesh sieve granulate, adds the magnesium stearate mix homogeneously again, tabletting, coating is made.
Effect to each component reaches selected being described as follows below:
1, coffee is because central stimulants is share the treatment migraine with Ergotamine for many years, and its migraine effect is relevant to cerebrovascular contraction with it.It can reach the migrainous effect of treatment by anticoagulant.
2, the general bitter edible plant Luo Er of hydrochloric acid is the beta receptor blocker, and its migraine mechanism prevents that with its beta receptor blocking-up the outer vasodilation of cranium is relevant.But heavy dose of Propranolol anticoagulant reduces the 5-HT receptor, and these effects show the migraine effect with preventing intracranial from shrinking relevant.
3, phenytoin Sodium is the sick medicine of epilepsy, also is used for the treatment of migraine, and is relevant with its membrane stabilizing action.
Pathogenesis of migraine mainly is because platelet function abnormality discharges a large amount of 5-HT, cause that entocranial artery shrinks, so that cerebral hypoxia, angiogenic substances such as histamine and Kallidin I are increased, 5-HT is destroyed rapidly simultaneously, thereby makes the outer arteriectasia of cranium cause migraine.Therefore, all energy antagonism 5-HT function of receptors, the medicine that increases outer tremulous pulse resistance of cranium or antiplatelet aggregation all has the effect of alleviation and prevention of migraine outbreak.
Contained caffeine, propranolol hydrochloride, the phenytoin Sodium of the present invention all can influence some link of migraine morbidity, so share " the migraine sheet " of composition, the three aspect treatment, can produce following beneficial effect: 1, antiplatelet aggregative activity, three medicines have synergism, thereby prevent the entocranial artery spasm; 2, prevent the outer arteriectasia aspect of cranium, caffeine and propranolol hydrochloride have synergism, thereby increase the outer tremulous pulse resistance of cranium, alleviate migraine; 3, membrane stabilizing action, propranolol hydrochloride and phenytoin Sodium have synergism, and the pain sensation due to the retardance vasodilation is conducted strong effect; 4, the central inhibitory action of propranolol hydrochloride and phenytoin Sodium can be weakened by caffeine; 5, the used dosage of migraine sheet is significantly less than each prescription dosage, each oral 1 of migraine sheet, every optimum content is caffeine 70mg, hydrochloric acid naphthalene Luo Er 10mg, phenytoin Sodium 100mg, and their common dose is respectively 100mg-300mg, 80mg-120mg and 100mg-200mg, because the used dosage of migraine sheet is little, so side effect is lowered greatly.The present invention shows that through the clinic trial result total effective rate reaches more than 93%.
