Abstract

The invention discloses an oral preparation of monosialotetrahexosyl ganglioside sodium, belongs to the field of medicines, and aims at solving the problems that a monosialotetrahexosyl ganglioside sodium injection hurts a human body and is high in cost. A monosialotetrahexosyl ganglioside sodium tablet is prepared from monosialotetrahexosyl ganglioside sodium, a filler, a drying adhesive, a disintegrating agent and a lubricant; and a hard capsule of monosialotetrahexosyl ganglioside sodium is prepared from monosialotetrahexosyl ganglioside sodium, a diluent, a lubricant, a glidant, a disintegrating agent and a wetting agent. The oral preparation has the advantages of relatively low cost, small medication pain and high medicine effect.

Description

technical field [0001] The invention belongs to the field of medicines; in particular, it relates to an oral preparation mainly composed of monosialotetrahexosyl ganglioside sodium, including tablets and hard capsules. Background technique [0002] The structural formula of monosialotetrahexosyl ganglioside sodium: [0003] [0004] The molecular formula of monosialotetrahexosyl ganglioside sodium is C 73 h 130 N 3 NaO 31 or C 75 h 134 N 3 NaO 31 The molecular weight is 1568.84 or 1597.18. [0005] Monosialotetrahexosyl ganglioside sodium is a substance that is extracted from pig brain and has an effect on nerve cell function damage. It can promote the functional recovery of central nervous system damage caused by various reasons. The mechanism of action is to promote "Neural remodeling neuroplasticity" (including survival of nerve cells, axon growth and synaptogenesis) monosialotetrahexosyl ganglioside is protective against secondary neurodegeneration after inju...
