Abstract

The invention provides a flunarizine orally disintegrating tablet, which consists of flunarizine and pharmaceutic adjuvant, wherein the pharmaceutic adjuvant comprises a filler, a disintegrating agent, a flavoring agent, an effervescing agent, a lubricating agent and the like. Compared with the disintegrating time limit of a common flunarizine tablet, the flunarizine orally disintegrating tablet has the characteristic of quick response. Mouthfeel observation experiments show that the flunarizine orally disintegrating tablet has good mouthfeel and is easy to be accepted by the patient. In vitro dissolution experiment results show that the bioavailability of the flunarizine orally disintegrating tablet is obviously higher than that of the common flunarizine tablet. The flunarizine orally disintegrating tablet can be quickly dispersed without water or swallow action, and has the advantages of no sand feel, good patient compliance, quick response, and high bioavailability; meanwhile, the preparation process is simple and suitable for industrial production.

Description

technical field [0001] The invention relates to a pharmaceutical preparation, in particular to an orally disintegrating tablet dosage form, in particular to a flunarizine orally disintegrating tablet and a preparation method thereof. Background technique [0002] Flunarizine, chemical name (E)-1-[bis(4-fluorophenyl)methyl]-4-2(2-propenyl-3-phenyl)-piperazine, is a calcium channel Blocker drugs. The main pharmacological effects of flunarizine are: (1) relieve vasospasm, and have a lasting inhibitory effect on the persistent vasospasm caused by vasoconstrictor substances, especially on the basilar artery and internal carotid artery, and its effect is stronger than that of naoyizine 15 times; (2) vestibular inhibition, can increase cochlear arteriole blood flow, improve vestibular organ circulation; (3) antiepileptic effect, can block pathological calcium overload of nerve cells and prevent paroxysmal depolarization, cell (4) protect the myocardium and significantly reduce is...
