Description
Invention field
The present invention relates to pharmaceutical field, relate in particular to the transdermal patch field of containing beta-Asarone.
Technical background
Beta-Asarone is the main component of Rhizoma Acori Graminei volatile oil, and central nervous system, cardiovascular system, respiratory system, digestive system are all had certain pharmacological action.Studies show that: beta-Asarone has dual regulation to the CNS irritability; The apoplexy rat model had alleviate cerebral edema, improve electroencephalogram, improve the effect of hypoxia-bearing capability, and can protect brain cell, significantly suppress brain cortex and hippocampal neurons apoptosis, suppress bax gene expression, and promote bcl-2 gene expression; Beta-Asarone has the effect of vasodilator, platelet aggregation inhibitory activity, points out it that cerebrovascular accident is had preventive and therapeutic effect; Beta-Asarone has inhibitory action to the animal brain electricity.
U.S. Harvard Medical School studies have shown that in the multiple composition of Rhizoma Acori Graminei; α-asaricin; three monomers of beta-Asarone and cis methylisoeugenol shield to the apoptosis of the inductive PC12 cell of amyloid beta; eugenol; beta-Asarone; 3 kinds of monomers of α-asaricin can stop the interior stream of intracellular calcium; the nerve cell death rate is obviously reduced; and the apoptotic cell quantity that A β is caused significantly reduces; has anti-apoptotic effect (Yoshifumi Irie, Wing Ming Keung.Rhizoma acori graminei and its active principlesprotect PC-12 cells from the toxic effect of amyloid-β peptide.Brain Research.2003.963.282-289).The research of Liao etc. points out, Rhizoma Acori Graminei is to the effect of cental system, can explain by the GABA binding site that Rhizoma Acori Graminei acts on dopamine D 1 and D2 receptor and GABA receptor, and confirm that α-asaricin is inoperative in this process.That prompting is worked may be beta-Asarone (Liao JF, Huang SY, Jan YM, Yu LL, Chen CF.Central inhibitory effects of waterextract of Acori graminei rhizoma in mice.J Ethnopharmacol.1998.61 (3) .185-93).Beta-Asarone and α-asaricin are by blocking N (NMDA) receptor; protection brain cortex cell; alleviate neurotoxic injury effect (the Cho J that causes by NMDA or glutamic acid; Ho Kim Y; Kong JY; Ha Yang C; Gook Park C.Protection of cultured rat corticalneurons from excitotoxicity by asarone, a major essential oil component in the rhizomes ofAcorus gramineus.Life Sci.2002.71 (5) .591-599).
The beta-Asarone pharmacokinetic data shows, its half-life at rat blood serum is 52min, transdermal time 3min, peak time 12min reaches peak concentration 3.19mg/L, in each organ (except that liver, kidney), brain has higher distribution, the prompting have first pass effect of hepar (Wu Hongbin, Fang Yongqi. beta-Asarone is in pharmacokinetics in rats. Acta Pharmaceutica Sinica, 2004,39 (10): 836-838).
Transdermal drug delivery system (TTS) is meant after the skin administration, medicine rapid permeability skin, enter blood circulation and play the controlled release preparation of whole body therapeutic effect, the distinct advantages that has: avoided contingent liver first-pass effect of oral administration and gastrointestinal deactivation, improved therapeutic effect; Keep constant blood drug level or pharmacodynamics effect, strengthened therapeutic effect, can not produce the blood drug level peak valley undulatory property that oral administration produces; Prolong action time, reduce the medication number of times, strengthened patient's compliance, be particularly suitable for inaccurate old people is unfamiliar with or is remembered to dosage regimen; Patient independently medication also can end medication at any time.

The effect experiment of beta-Asarone transdermal plaster of the present invention is as follows:
1) beta-Asarone vitro skin penetration kinetics test
The standard curve preparation: precision takes by weighing beta-Asarone reference substance 4.4mg, puts in the 50ml volumetric flask, adds dissolve with ethanol and is diluted to scale, preparation storing solution (88 μ g/ml).Accurate absorption 2,1,0.2,0.5ml storing solution are diluted with ethanol to scale in the 10ml measuring bottle, be made into 17.6,8.8,1.76,0.44 μ g/ml beta-Asarone reference substance solution, and sample introduction is measured.With peak area integrated value (X) beta-Asarone mass concentration (Y) is returned, must mark Huaihe River curve Y=3.86 * 10
-4X+6.38 * 10
-3, (r=0.9995).Show that beta-Asarone has the good linear relation at 4.4～1320ng and peak area, precision, study on the stability all reach standard.
Preparation of isolated rat skin and processing: get adult male SD rats, body weight 300g～350g anaesthetizes with 10% chloral hydrate 0.3ml/100g.Get skin of back, strip skin after shaving off hair, remove subcutaneous fat, with ice normal saline flushing 3 times.Skin is put-4 ℃ of refrigerators and preserved, took out in second day, thaw naturally, clean with normal saline flushing.The skin of handling well is fixed on for medicine pond and accepting between the pond, and stratum corneum side is to for the medicine pond, and skin corium contacts with acceptable solution towards accepting the pond.
The preparation of beta-Asarone dicyandiamide solution and reception liquid: get the 0.2mg beta-Asarone and be dissolved in 20ml ethanol, be diluted with water to 100ml, as dicyandiamide solution I; Get the 0.2ml beta-Asarone and the 0.1g Borneolum Syntheticum is dissolved in 20ml ethanol, be diluted with water to 100ml, as dicyandiamide solution II; Get 0.2ml beta-Asarone, 0.1g Borneolum Syntheticum and 1ml aqueous azone and be dissolved in 20ml ethanol, be diluted with water to 100ml, as dicyandiamide solution III; Get 0.2ml beta-Asarone, 0.1g Borneolum Syntheticum and 3ml aqueous azone and be dissolved in 20ml ethanol, be diluted with water to 100ml, as dicyandiamide solution IV; Get 0.2ml beta-Asarone, 0.1g Borneolum Syntheticum and 5ml aqueous azone and be dissolved in 20ml ethanol, be diluted with water to 100ml, as dicyandiamide solution V; Take by weighing 0.9g sodium chloride and be dissolved in 100g 20% ethanol, promptly get and receive liquid.
The Transdermal absorption experiment: rectilinear diffusion cell is accepted the long-pending 6.5ml of being of cell body by supplying the medicine pond and accepting the pond and form, and the effective diffusion area of Chi Kou is 2.8cm
2Diffusion cell places the water bath with thermostatic control circulating box to keep 37 ℃, accepts the mid-magnetic stir bar in pond, constantly stirs with 250r/min speed.Acceptable solution added accept to contact closely in the pond and with skin corium, and note draining bubble from sample tap.Start infiltration diffusion test instrument 30min stable after, the different solvents system that will contain beta-Asarone adds in the medicine pond.0.5,1,2,3,5,7,10,13,23,24h draws acceptable solution 1,1,1,1,2,2,2,5,3,1ml respectively and replenishes the isothermal blank acceptable solution of equivalent simultaneously.The acceptable solution of drawing is crossed 0.45 μ m microporous filter membrane, gets subsequent filtrate and measures.
The percutaneous accumulation infiltration capacity of medicine (M) is calculated: owing to after getting acceptable solution, add the equivalent blank simultaneously and connect liquid at every turn, it is low therefore to record the concentration ratio actual concentration, so different sample point M value is pressed the correction that establishes an equation.
C in the formula
nAcceptable solution measured concentration during for different sample point, V is for accepting cell body long-pending (6.5ml), and Vs (n-1) is the sample volume of different time points, and A is effective diffusion area (2.8cm
2).With the accumulation transit dose time is carried out linear regression, the slope of gained equation is infiltration rate P.
