The invention belongs to the field of pharmaceutical preparations, and particularly relates to a
butylphthalide solid drug release
system, a preparation method thereof and a pharmaceutical preparation. The
butylphthalide solid drug release
system comprises the following components: a
microemulsion and an adsorption carrier, the
microemulsion comprises
butylphthalide and an emulsifier
system, preferably, the emulsifier system comprises an emulsifier and a co-emulsifier. The obtained butylphthalide
solid self-
microemulsion has the advantages of good emulsifying capacity of liquid self-microemulsion and good stability of a solid preparation, has a very good
drug solubilizing effect, can improve the probability that a drug is absorbed by gastrointestinal tracts in a dissolved state, improves the oral
bioavailability of butylphthalide, and further improves the
drug effect; moreover, the solid self-microemulsion is good in stability and low in
toxicity, liquid
medicine solidification is achieved, and the problem that a liquid preparation is inconvenient to transport, store and take is solved.
