Description

Oxycodone hydrochloride and ibuprofen compound recipe multilayer tablet and preparation method thereof
Technical field
The invention belongs to field of pharmaceutical preparations, relate to oxycodone hydrochloride and ibuprofen compound recipe multilayer tablet and preparation method thereof.
Background technology
Pain belongs to a kind of commonly encountered diseases, and its sickness rate in China adult, up to more than 40%, can occur in each organ of health, as dysmenorrhea, and headache, migraine, cancer pain, musculoskeletal pain, postoperative pain, the pain etc. of empyrosis.Current clinical conventional analgesic has two kinds: one class to be take morphine as the narcosis analgesic of representative, and another kind of is take aspirin as the antipyretic analgesic of representative.Although the former analgesia intensity is high, additive is its fatal weakness, significantly limit its application; Though the latter, without additive but its analgesia intensity is weak, and has serious the intestines and stomach effect.Combunox is first is also a unique fixed dosage compound medicines be made up of opium analgesics oxycodone hydrochloride (OxycodoneHCl, 5mg) and NSAID (non-steroidal anti-inflammatory drug) (NSAID) ibuprofen (Ibuprofen, 400mg).Combunox is developed by Forest company, obtains FDA approval listing on November 26th, 2004, for most of wound or Post operation acute in the short-term process (within 7 days) of severe pain.Combunox single-dose, its analgesic effect be better than the oxycodone of low dosage or ibuprofen individually dosed, also than some other compound pain medicine better effects if.This medicine single or multiple drug tolerance is good, and short-period used can not produce the relevant serious adverse reaction of opioid drug or NSAID class medicine life-time service.This medicine is considered to acute, in severe pain effectively and select easily.
US4569937 and WO2004050025 patent all discloses oxycodone and directly mixes with adjuvant with ibuprofen, direct compression, or tabletting or encapsulated after wet granulation.US4569937 finds two medicine synergism, can reduce consumption and toxic and side effects.WO2004050025 as filler and fluidizer, substitutes microcrystalline Cellulose with silicified microcrystalline cellulose (particle diameter 1nm-100um), produces tissue adhesion effect, be beneficial to tabletting, but silicified microcrystalline cellulose price is abroad high, and cannot buy China is domestic, belong to that valency is high is not easy to obtain adjuvant.The coating powder that WO2004050025 also discloses coating is Opadry coating powder, but Opadry model is many, and not every Opadry coating powder is all suitable for the coating of ibuprofen oxycodone.Two sections of patents all do not report that oxycodone mixes with adjuvant with ibuprofen, the stability problem of preparation after tabletting.
Inventor is found by a large amount of experiments, in the common compound tablet preparation process of oxycodone hydrochloride and ibuprofen, oxycodone hydrochloride easily interacts with multiple binding agent, lubricant and produces degradation impurity, especially, when ibuprofen and oxycodone coexist, oxycodone hydrochloride degraded is more remarkable.
In the common compound tablet preparation process of oxycodone hydrochloride and ibuprofen, granulate after ibuprofen, oxycodone hydrochloride, binding agent mix with disintegrating agent, add fluidizer again, lubricant pressure conventional tablet, under room temperature and hot conditions, all can produce very large impurity, wherein the impurity content of high temperature is far above the upper limit of pharmacy quality control.
Causing impurity Producing reason to find, after ibuprofen mixes with oxycodone by our difference (1), then mixing with multiple disintegrating agent; (2) after ibuprofen being mixed with oxycodone, then mix with multiple binding agent; (3) after ibuprofen being mixed with oxycodone, then mix with multiple fluidizer; (4) after ibuprofen being mixed with oxycodone, then with multiple mix lubricant.Research all can produce very large impurity under there is room temperature and hot conditions after finding that ibuprofen mixes with binding agent with oxycodone hydrochloride, and wherein the impurity content of high temperature is far above the problem of the upper limit of pharmacy quality control.In multiple binding agent, when doing binding agent with polyvidone, the degraded of oxycodone hydrochloride is very serious, when coexisting with other binding agents, also there is degraded (see Table A) in various degree, when doing binding agent with hydroxypropyl emthylcellulose (HPMC), the degraded of oxycodone is minimum.And not having ibuprofen to deposit in case, between oxycodone hydrochloride and various binding agent, the compatibility has clear improvement, but when coexisting with domestic polyvidone k30, still has larger degraded (table B).
In the preparation process of the common compound tablet of ibuprofen oxycodone subsequently, we select the less HPMC(that to degrade with ibuprofen oxycodone to select different manufacturers, the HPMC of different batches), hydroxypropyl cellulose and sodium carboxymethyl cellulose be as binding agent, adopt conventional wet granulation technology, sample is placed in room temperature and hot conditions respectively, find different manufacturers, the HPMC of different batches is binding agent and two kinds of principal agent mixing wet granulations, the degraded still disunity of oxycodone hydrochloride, its quality uncontrollable (see table C).Doing binding agent with HPMC in addition, when making lubricant with magnesium stearate, sodium stearyl fumarate, the degraded of oxycodone has again obviously increases, and impurity content is far above the upper limit (table D) of pharmacy quality control.
Pharmaceutical preparation in preparation process, drug quality is controlled to be conducive to batch between diversity reduce, be conducive to reducing due to batch between the weak curative effect opposite sex that causes of difference.The degraded of pharmaceutical preparation principal agent in storage process in addition, meeting and then lessen the curative effect.In order to avoid the harmful effect that above-mentioned situation is brought, need to find a kind of solution oxycodone, ibuprofen and binding agent further, drug content degraded when lubricant coexists, and the uncontrollable method of quality.
