Description

The composition of hydrophilic polymer
Technical field
The present invention relates to a kind of composition of hydrophilic polymer.It particularly relates to a kind of disintegration (or swelling) performance changes The composition of kind hydrophilic polymer.
Technical background
Medicinal hydrophilic polymer can make disintegrant or retarding agent in pharmacy, reach for accelerating or delaying insoluble drug release Expected purpose.Its principle absorbs water to form dilatant to achieve the goal by medicinal hydrophilic polymer.
However, these contact the hydrophilic polymer of swellable work " disintegrant " or " retarding agent " with water, easily occur " in salt Poison " effect and " gel blockage " effect, (can be subject to other peripheral stroma materials particularly under artesian condition when expanding The reaction force of " four walls ")." salt poisoning " effect (implication in lower section is herewith) refers to contact with water swellable hydrophilic herein Polymer, particularly under artesian condition, in the aqueous solution such as physiological saline, urine, menses, vagina containing electrolyte (salt) Body fluid, the phenomenon that is substantially reduced relative to deionized water of the ability of water absorption and swelling in the body fluid in rectum;" gel hinders herein It is wetted and be swollen, suppression that plug " effect (implication in lower section is herewith) refers to contact swellable hydrophilic polymer particles with water Fluid has been made to other regions such as interior shifting of particle and the phenomenon for inhibiting particle to be further swollen, it is so-called just as being formed The phenomenon of " not and open dough ", will be more serious particularly under artesian condition.The main reason for producing gel blocking phenomenon It is that particularly under artesian condition, the gap between particle is reduced and viscosity increase after swelling.
The hydrophilic polymer that swellable work " disintegrant " or " retarding agent " are contacted with water occurs " salt poisoning " effect and " coagulates After glue obstruction " effect, for swelling behavior with after larger change occurs, some polymer particles graininesses fail effectively expansion or fully swollen It is swollen, so that pharmaceutical preparation fails substantially or completely to be disintegrated, thus pharmaceutical preparation drug release rate can be caused to slow down even substantially not The problems such as drug release.
Particularly in slow (/ control) release formulation, because hydrophilic polymer graininess fails effectively expansion or fully expansion, the system Agent, which is also possible that, even to be there is the release of medicine rapid abnormal by faster drug release dosage inclines and releases (dose-dumping) in other words Deng drug safety problem.
Thus, the insoluble drug release behavior of the pharmaceutical preparation containing these hydrophilic polymers will likely become unstable, such as release The possible substantial deviation of medicine speed is expected, too fast or excessively slow, or even is not released the drug or inclined suddenly substantially and release;In addition, insoluble drug release behavior Unstable to further include front and rear drug release rate non-constant, inconsistent, and early period, drug release was fast, partially slow (the same ionic strength of later stage drug release Under (salinity) or under same drug release medium).
This implies that the pharmaceutical preparation containing these hydrophilic polymers preferably has to provide stable drug release pattern, special It is not to have to avoid rate of releasing drug excessive variation in the medium of the ionic strength (salinity) of change, because gastrointestinal cavity content The ion-intensity values (salinity) of change are presented in the different region of intestines and stomach.The ion-intensity values (salinity) run into the gastrointestinal tract Not only with the regional change of intestines and stomach, but also change with the intake of food, said medicine preparation preferably also has to provide stabilization Drug release pattern and especially have to avoid no matter patient is under fasting or fed condition from providing stable insoluble drug release Pattern.The ionic strength of gastrointestinal fluid can between about 0.01 to about 0.2 (Johnson etc., 1993, Int.J.Pharm., 151-159)。
Ionic strength, in most cases by symbol μ (being sometimes I) represent, for solution characteristic and be defined as:
Wherein ciFor the molar concentration of i-th of ion, ZiFor its electric charge, and the summation includes all ions in solution (Martin, A., 1993,134-135 pages of Physical Pharmacy, Williams&wilkins, the), reflects solution Salinity.On the ion that known electrolyte specific in by solution produces, the foundation of ionic strength can be measured well by solution All ions influence imperfection.
There is the ionic strength (salinity) that surrounding medium is described in document to the pharmaceutical preparation containing these hydrophilic polymers Calving disaggregation, the influence in gelatification and viscosity.
Mitchell etc. (insoluble drug release of pharmaceutical technology control, volume 2, Wells, J.I., Rubinstein, M.H. (editor), Ellis Horwood Limited, the 23-33 pages, 1991) open electrolyte is to hydroxypropyl methyl cellulose (HPMC) calving disaggregation of K15M substrate tablets and the influence of gelatification.Under the low ionic strength of surrounding medium, HPMC matrix is not By Influence of Electrolyte and the complete gel layer of aquation generation occurs.However, under moderate ionic strength, matrix loses shape And integrality, and their rapid fragmentations.Tablet stopping is used as slow (/ control) to release matrix and works, because in surrounding medium is increased Solute concentration in the case of, gelatification is hindered by the reduction of aquation.Accordingly, there exist the electricity in surrounding medium Solution matter can improve medicine from the release mode in HPMC matrix.Medicine can also influence aquation and therefore influence in itself The gelatification of HPMC.Therefore, medicine can have a positive effect in the release of themselves is measured (Mitchell etc., Int.J.Pharm., 1993,100,165-173).So medicine, which is admixed in HPMC matrix, can lead to not expected disintegration Therefore pattern simultaneously causes the unexpected therapeutic effect of formulation.
In Int.J.Pharm., chlorine of the xanthan gum matrix tablet in different ionic strength described in 1995,120,63-72 Change the swelling behavior in sodium solution.In the range of physiological ionic strength, the swelling of xanthan gum tablet is shown and salinity phase Mutual correlation.
The detrimental effect of insoluble drug release behavior of the above-mentioned ionic strength to the pharmaceutical preparation containing these hydrophilic polymers, can It is attributed to the change of the aquation of the hydrophilic polymer of viscosity.The hydrophilic polymer have to composition dissolution medium from The solute of sub- intensity competes hydrate water.So polymer can not be hydrated such degree to ensure to have and can connect to disintegration The matrix of the sufficiently complete for the resistance received is formed.The hydration (disintegration) (effect) of the matrix polymer can be great or even complete It is complete to be suppressed that almost fragmentation immediately triggers to incline suddenly and releases so that slow (/ control) release formulation is in dissolution medium mesostroma, or make general Disintegrant in logical tablet loses calving disaggregation completely and can not release the drug or prolonged disintegration makes drug release slack-off.
Therefore, also need to improve in reality or improve purposes of the above-mentioned hydrophilic polymer in pharmacy.
Following patent provides as reference.
