Description
Technical field
The invention belongs to technical field of medicine, and in particular to a kind of Pregabalin capsule and preparation method thereof.
Background technique
Pregabalin belongs to non-γ-aminobutyric acid (GABA) receptor stimulating agent or antagonist, is that a kind of novel agents of calcium ion is logical
Road regulator, energy blocking voltage dependent calcium channel, reduces the release of neurotransmitter.Clinic is mainly used for Diabetic Peripheral mind
Through the related neuralgia of lesion, postherpetic neuralgia and adjuvant treatment the epileptic attack of adult partial's property, generalized anxiety disorder, in
Pivot neuralgia (including spinal cord injury, stroke and the adjoint neuralgia of multiple sclerosis) and fibromyalgia.
On the one hand, since there are primary amino groups and carboxyl for Pregabalin intramolecular, intramolecular condensation easily occurs and generates interior acyl
Amine, this intramolecular condensation phenomenon is more obvious especially under wet heat condition.And the primary amino group in Pregabalin is damp and hot
Under the conditions of be also easy to and mailland reaction occurs for carboxyl in lactose molecule.Therefore, wet granulation (is especially filling with lactose
The wet granulation of agent) be not suitable for preparing Pregabalin capsule.
On the other hand, the very poor compressibility of Pregabalin is but also dry granulation is difficult to reach to form particle improvement mobility
Purpose prepares Pregabalin capsule to be not suitable for use in.
Summary of the invention
The purpose of the present invention is to solve the above problem, provides one kind and has preferable mobility and stability and mixing
The uniformity, the Pregabalin capsule for being suitble to industrialized production and preparation method thereof.
Realizing the technical solution of above-mentioned purpose of the present invention is: a kind of Pregabalin capsule, it be by Pregabalin, lactose with
And pharmaceutically acceptable carrier is made.
It has been found that the particle size of Pregabalin and lactose for Pregabalin capsule mobility and stability with
And mixture homogeneity is affected, for this purpose, applicant finally found that by a large number of experiments: when the D50 partial size of Pregabalin is 180
μm~220 μm, D90 partial size is 250 μm~280 μm and the D50 partial size of lactose is 120 μm~140 μm, D90 partial size is 160 μm
At~180 μm, obtained Pregabalin capsule is had preferable mobility and stability and mixture homogeneity.
Above-mentioned pharmaceutically acceptable carrier is mainly adhesive and lubricant.
Applicant further found that in Pregabalin capsule otherwise the content of Pregabalin will affect Puri bar no more than 50%
The mobility and stability and mixture homogeneity of woods capsule, therefore, in above-mentioned Pregabalin capsule, the weight hundred of Pregabalin
Divide than being 5%~50%, preferably 20%~30%.
In above-mentioned Pregabalin capsule, the weight percent of lactose is 10%~60%, preferably 25%~35%.
In above-mentioned Pregabalin capsule, the weight percent of adhesive is 20%~80%, preferably 32%~48%;It is described viscous
Mixture is in starch, PVP K30, hydroxypropyl cellulose, hypromellose, methylcellulose and ethyl cellulose
One or two kinds of, preferably starch.
In above-mentioned Pregabalin capsule, the weight percent of lubricant is 1%~10%, preferably 3%~7%;The lubrication
Agent is selected from one of magnesium stearate, talcum powder, silica and hydrogenated vegetable oil or two kinds, preferably magnesium stearate.
The preparation method of above-mentioned Pregabalin capsule has follow steps:
1. Pregabalin raw material is crossed 30 mesh (600 μm of aperture) sieve on oscillating granulator, the Puri of 30 meshes will be crossed
Bahrain's raw material successively crosses 60 mesh (250 μm of aperture) sieve and 80 mesh (180 μm of aperture) sieve again, took 60 meshes and did not crossed 80 mesh
The pregabaline particles powder of sieve, it is spare;
2. being taken 80 mesh (180 μm of aperture) sieve and 120 mesh (120 μm of aperture) sieve is successively crossed on lactose earthquake sieve
It crosses 80 meshes and does not cross the lactose granule powder of 120 meshes, it is spare;
3. (D50 partial size is 180 μm~220 μm to the pregabaline particles powder for first 1. obtaining step, and D90 partial size is 250
μm~280 μm) be uniformly mixed on Mixers with Multi-direction Movement with adhesive, the cream that then 2. addition lubricant and step obtain
Sugared particle powder (D50 partial size is 120 μm~140 μm, and D90 partial size is 160 μm~180 μm), continuess to mix uniformly, will finally mix
It closes uniform material and directly filling obtains Pregabalin capsule on fully-automatic capsule filling machine.
The good effect that the present invention has: Pregabalin and lactose are first passed through sieving technology respectively and are made appropriate by the present invention
Partial size, then the pharmaceutically acceptable carriers such as adhesive and lubricant is cooperated to prepare Pregabalin capsule, can be flowed
Property and stability and the preferable Pregabalin capsule of mixture homogeneity, to be suitble to industrialized production.
