A further object of the present invention has provided a kind of method for preparing that contains Zolpidemtar Trate active component slow-release micro-pill, comprises pastille base ball is placed fluid bed or coating pan, wraps slow release layer, is drying to obtain.Wherein, Containing the pill core segment can be to process micropill by Zolpidemtar Trate and after filling adjuvant, binding agent, mix lubricant, also can medicine be invested on the blank basic ball with methylcellulose or pharmaceutically acceptable medicinal materials spray such as hypromellose or polyvidone.Fill adjuvant and comprise one or more acid adjuvants of regulating such as organic acid of molding adjuvant such as lactose, starch, microcrystalline Cellulose or tartaric acid, citric acid, ethanedioic acid, malic acid and fumaric acid and their acid salt thereof; Binding agent comprises pharmaceutically acceptable medicinal materials such as sucrose, methylcellulose, hypromellose, polyvidone; Lubricant comprise magnesium stearate, stearic acid, colloidal silica, Pulvis Talci etc. pharmaceutically acceptable one or more.
For purposes such as attractive in appearance or the moistureproof lucifuge of moisture-resisting can attach general thin clothing layer in the outsourcing of pastille release layer.
Described general thin clothing layer is joined clothing liquid bag by methylcellulose or pharmaceutically acceptable medicinal materials such as hypromellose or polyvidone and is attached and form.Can contain pharmaceutically acceptable film material additives such as pigment, opacifier and plasticizer in its coating material.
Concrete method for preparing comprises the following steps:
(1) contain the preparation of pill core:
A. fillibility adjuvant and medicament mixed is even, add binding agent, play female also pill-rolling to required order with comminutor (or coating pan) and count 15-30 order (pill-rolling limit, limit adds lubricant), oven dry makes smooth ball-shaped and contains pill core.
B. with fillibility adjuvant mix homogeneously, add binding agent, play female also pill-rolling to required order with comminutor (or coating pan) and count 15-30 order (pill-rolling limit, limit adds lubricant); Oven dry; Make the blank basic ball of smooth ball, the basic ball of blank is placed fluid bed (or coating pan), make the temperature of basic ball be controlled at 35-60 ℃; With water or water and alcohol mixeding liquid, the skin that is coated on the blank basic ball of ball is processed and is contained pill core with Zolpidemtar Trate and hypromellose or polyvidone or methylcellulose.
(2) coating of slow release layer
To contain pill core and place fluid bed (or coating pan); Make the temperature of micropill be controlled at 20-50 ℃; Blocker, porogen, plasticizer, antiplastering aid are mixed with solution or suspension with water or water and alcohol mixeding liquid, are sprayed at the skin that contains pill core and process slow-release micro-pill.
(3) release layer coating
Slow-release micro-pill is placed fluid bed (or coating pan); Make the temperature of micropill be controlled at 20 ℃-50 ℃, with Zolpidemtar Trate, hypromellose or polyvidone or methylcellulose or and the water that is used of organic acid or water and alcohol mixeding liquid be mixed with solution or suspension and be coated on outer system.
The present invention compares with ordinary preparation according to the slow-release micro-pill of technical scheme 1 preparation has following characteristics:
(1) 20%-60% of the Zolpidemtar Trate total amount that discharges of 30 minutes slow-release micro-pill drug release determination initial stages makes drug effect; Slowly discharge residual drug in remaining time, this kind method for preparing can not cause that local blood concentration is too high and the situation in stimulating gastrointestinal road is kept effective blood drug concentration simultaneously.The deficiency that the blood drug level peak-to-valley ratio is excessive, action time is too short of having avoided ordinary preparation to exist has increased safety, has improved therapeutic effect.Dissolve total release time fully in 1-6 hour, preferred 1.5-5.0 hour.
(2) amass according to ball core different surface, adjust the size of drug loading, to reach required drug release rate; Also can reach required dissolution rate, in the design of formulation and technology, have flexible and changeable advantage through the mixed proportion and the spraying consumption of adjustment polymer.
(3) because the flowability of spheroidal micropill better, in the process of coating medicine and polymer, can obtain higher productive rate and repeatability, be easy to industrialization.
The present invention compares with ordinary preparation according to the slow-release micro-pill of technical scheme 2 preparations has following characteristics:
(1) the about 40%-70% of Zolpidemtar Trate that discharges of 30 minutes slow-release micro-pill drug release determination initial stages makes medicine onset at short notice; Slow-released part slowly discharges remaining, can not cause that local blood concentration is too high and the situation in stimulating gastrointestinal road is kept effective blood drug concentration simultaneously.The deficiency that the blood drug level peak-to-valley ratio is excessive, action time is too short of having avoided ordinary preparation to exist has increased safety, has improved therapeutic effect.Dissolve total release time fully in 1.5-6 hour, preferred 2.5-5.5 hour.
(2) slow-released part and immediate release section consubstantiality, avoided slow-released part to mix bringing with the immediate release section proportioning because the layering that weight factor causes makes preparation have potential safety hazard.

Bag pharmaceutical worker skill: distilled water is mixed with ethanol, add Zolpidemtar Trate, hypromellose and tartaric acid, make dissolving; The pastille slow-release micropill is placed fluid bed, and reconciling EAT is 40 ℃, with the flow velocity of 5ml/min medicinal liquid is sprayed onto end, after the drying, measures intermediate content, filling capsule.
Embodiment 13 drug release determination methods 1:
The Zolpidemtar Trate active component slow-release micro-pill that contains of the present invention has carried out the comparative experiments of release in vitro degree.
The drug release determination method:
These article of getting; According to drug release determination method [Chinese Pharmacopoeia version appendix in 2005 XD second method (1)], adopt dissolution method second subtraction unit, be dissolution medium with 0.1mol/L hydrochloric acid solution 750ml; Rotating speed is that per minute 50 changes; Operate the 5ml that takes a sample through 0.5h, 1h, 1.5h, 2h, centrifugal (3500 rev/mins) 5 minutes are got supernatant as test sample 1 in accordance with the law.Add isothermal 0.2mol/L sodium radio-phosphate,P-32 solution 250ml then, mixing continues timing and in 2.5h, 3h, 4h sampling, with the method operation, as test sample 2; Reference substance solution, it is an amount of to get Zolpidemtar Trate, and being made into concentration is that 10 μ g/ml hydrochloric acid solutions are as contrast liquid.According to ultraviolet spectrophotometry (Chinese Pharmacopoeia version appendix in 2005 IV A), measure absorbance in the 294nm wavelength, measure burst size.Embodiment 1,2,3 and 6 uses this method and measures, and concrete sampling time point is suitably adjustment as required.
Embodiment 14 drug release determination methods 2:
These article of getting are according to dissolution method (two appendix XC of Chinese Pharmacopoeia version in 2005, second method); 1000ml is a dissolution medium with water (or hydrochloric acid solution (9 → 1000) or pH6.8 phosphate buffer), 50 rev/mins of rotating speeds, operation in accordance with the law; Through 0.25h, 0.5h, 1h, 2h, 3h, 4h, 5h, 6h and 7h; Get solution 5ml, centrifugal (3500 rev/mins) 5 minutes are got supernatant as need testing solution.Reference substance solution, it is an amount of to get Zolpidemtar Trate, and being made into concentration is that 10 μ g/ml hydrochloric acid solutions are as contrast liquid.Measure absorbance according to spectrophotography (two appendix IVA of Chinese Pharmacopoeia version in 2000) in the wavelength of 294nm, measure burst size.Embodiment 4,8 and 9 uses this method and measures, and concrete sampling time point is suitably adjustment as required.
