Description

글리메피리드를 가용화시켜 투명 내용액으로 함유한 연질캅셀제{Soft capsule containing transparent solubilized glimepiride solution as core ingredient} Soft capsule containing transparent solubilized glimepiride solution as core ingredient}             

본 발명은 글리메피리드의 용출을 보다 신속하게 향상시킬 수가 있는 제형으로써 글리메피리드를 가용화시킨 내용물을 함유하는 연질캅셀 제형 및 그의 제조방법에 관한 것이다.The present invention relates to a soft capsule formulation containing a content of solubilized glymepiride as a formulation capable of improving the dissolution of glymepiride more rapidly, and a method for producing the same.

글리메피리드는 {1-[[p-[2-(3-에틸-4-메틸-2-옥소-3-피롤린-1-카르복스미돌)에틸]페닐]-설포닐]-3-(트랜스-4-메틸사이클로헥실)우레아} (C24H34N4O 5S : 490.6)로써 제 2세대 설폰요소제로써, 기존의 설폰요소제와는 수용체의 결합부위가 달라 설 폰요소제에서 나타날 수 있는 심혈관계 부작용의 위험의 적고 또한 작용시간이 길어 하루1회 투여로 효과를 볼 수 있는 약제이다.Glymepyride is {1-[[p- [2- (3-ethyl-4-methyl-2-oxo-3-pyrroline-1-carboxmidol) ethyl] phenyl] -sulfonyl] -3- (trans- 4-methylcyclohexyl) urea} (C 24 H 34 N 4 O 5 S: 490.6) as a second-generation sulfone urea, a cardiovascular side effect that may occur in sulfone urea due to a different binding site of receptors from conventional sulfon urea Low risk and long acting time of the drug can be effective once a day administration.

글리메피리드 약물은 글리부리드(영명: Glyvuride), 글리피지드(영명: Glipizide)와 함께 제 2세대 경구용 설폰요소제(Sulfonylurea (SU))의 하나로써 식이요법, 운동요법, 체중감량 등으로만 조절되지 않는 인슐린-비의존성 환자를 위한 치료제로써 인슐린과 동시에 쓸 수 있는 유일한 설포닐우레아로 1995년 FDA의 승인을 받았다.Glymepiride drug is one of the second generation oral sulfonylureas (SU) along with glyvuride (Glyvuride) and glipizide (Glyvuride) and is not controlled solely by diet, exercise and weight loss. Was approved by the FDA in 1995 as the only sulfonylurea to be used concurrently with insulin as a treatment for insulin-independent patients.

이러한 약리 작용을 갖는 글리메피리드 약물은 백색의 분말로 유기용매에 조금 용해되며, 물 또는 유성용제에 용해되지 않는 성질이 있다.Glymepiride drug having such a pharmacological action is a white powder, slightly soluble in an organic solvent, and insoluble in water or an oily solvent.

그러나 현재의 글리메피리드 약물은 기존의 제형이 정제로 되어 있는데 정제의 경우에는 약물이 글리메피리드와 같이 난용성의 제제의 경우에는 일반적으로 용출속도 및 용출율이 낮기 때문에 생체 흡수속도 및 생체 흡수속도 및 생체 이용률이 더디어서 약물의 발현에 문제가 있다.However, the current glymepiride drug has a conventional formulation as a tablet. In the case of tablets, in the case of a poorly water-soluble agent such as glymepiride, the dissolution rate and the dissolution rate are generally low. There is a problem with the expression of the drug.

한편 정제와 같은 기존 제형의 경우, 원료의 형상 또는 원료의 결정 형태에 따라 용출속도 및 용출율이 달라지는 등의 문제가 발생하지만 연질캅셀로 하여 가용화하는 경우 이와 같은 문제를 해결할 수 있다.On the other hand, in the case of existing formulations such as tablets, problems such as dissolution rate and dissolution rate vary depending on the shape of the raw material or the crystal form of the raw material, but such problems may be solved when solubilized using a soft capsule.

그러나 글리메피리드 약물을 연질캅셀 제형으로 하여 용출속도와 용출율을 향상시키고자 할 때에는 주성분 약물을 유성 또는 친수성 기제에 현탁시키는 방법으로써는 그 효과가 크지 않기 때문에 보다 용출속도와 용출율을 크게 향상시키기 위해서는 약물을 가용화시켜 연질캅셀의 내용물로 함이 요구되고 있다.However, in order to improve the dissolution rate and dissolution rate by using the glymepiride drug as a soft capsule, the method of suspending the main ingredient drug in an oily or hydrophilic base is not effective. It is required to solubilize the contents of the soft capsule.

특히 글리메피리드와 같은 난용성 약물을 가용화시켜 연질캅셀화 함으로써 생체 이용률을 향상시킨 연질캅셀 제형은 다른 난용성 약물의 경우 국내외적으로 개시된 바 있으며, 그 예로써 은행잎 엑기스 연질캅셀제 및 그의 제조방법(국내특허 제112,624호, 제138,500호, (주)서흥캅셀), 파모티딘을 가용화시킨 내용물을 함유한 연질캅셀제(국내특허 제201,906호, (주)서흥캅셀), 비페닐디메틸디카르복실레이트를 가용화시킨 연질캅셀제(국내특허 제201,907호, (주)서흥캅셀) 등을 들 수 있다.In particular, soft capsule formulations having improved bioavailability by solubilizing poorly soluble drugs such as glymepiride to soften the capsules have been disclosed at home and abroad for other poorly soluble drugs, for example, ginkgo biloba extract soft capsules and methods for preparing the same (domestic patent) Nos. 112,624, 138,500, Seoheung Capsule Co., Ltd., soft capsules containing the content of solubilized pamotidine (Domestic Patent No. 201,906, Seoheung Capsule Co., Ltd.), and solubilization of biphenyldimethyldicarboxylate Soft capsules (Domestic Patent No. 201,907, Seoheung Capsule Co., Ltd.), etc. may be mentioned.

그러나 글리메피리드의 가용화를 통한 연질캅셀 제형의 개발은 상기 개시된 난용성 약물의 경우와는 다른 적절한 가용화 방법이 요구되는 것이다.However, the development of soft capsule formulations via solubilization of glymepiride requires a different solubilization method than the poorly soluble drug disclosed above.


본 발명이 이루고자 하는 기술적 과제는 상기와 같이 기존 제형의 용출속도 및 생체 흡수 속도를 보다 향상시켜 당뇨병 환자에게 신속하게 약물의 발현이 나타나게 제형을 개발하기 위한 것으로써, 약물의 인체 흡수율 및 생체 흡수속도가 월등히 향상된 연질캅셀제를 개발하기 위한 것이다.

The technical problem to be achieved by the present invention is to improve the dissolution rate and bioabsorption rate of the existing formulation as described above to develop the formulation so that the expression of the drug quickly to diabetic patients, the human absorption rate and bioabsorption rate of the drug It is to develop an improved soft capsule.

그러나 연질캅셀 제형으로 할 경우에는 일반적으로 알려진 연질캅셀 내용물의 처방 및 제조 방법인 콩기름, 소맥배아유, 월견초종자유 등과 같은 식물유 또는 중쇄지방산트리글리세라이드(MCT)와 같은 유성의 성질을 갖는 기제에 밀납 등의 현탁화제를 사용하여 주성분 약물을 현탁시키는 방법으로 할 경우에는 난용성 약물일 때에는 약물의 용출속도와 용출율을 크게 향상시키기에는 어려움이 있다.
However, in the case of soft capsule formulations, beeswax in base oils such as vegetable oils such as soybean oil, wheat germ oil, moonshine seed oil, etc., or oily properties such as medium-chain fatty acid triglycerides (MCT), which are commonly prescribed and prepared methods of soft capsule contents In the case of using a suspending agent or the like to suspend the main ingredient drug, it is difficult to significantly improve the dissolution rate and dissolution rate of the drug in the case of poorly soluble drugs.

또한 상기의 일반적인 연질캅셀 내용물 처방 및 제조 방법 보다 다소 진보된 방법으로 알려진 폴리에틸렌글리콜 400∼600 등과 같은 친수성 액상 기제에 폴리에틸렌글리콜 1,500∼6,000 등과 같은 친수성 반고형상 또는 고상의 물질을 혼합하여 주성분 약물을 현탁시키는 방법으로 할 경우에도 상기의 방법보다는 다소 용출속도와 용출율이 좋아질 수도 있지만 그 효과를 크게 기대할 수는 없다.
In addition, the main ingredient drug is suspended by mixing a hydrophilic semisolid or solid substance such as polyethylene glycol 1,500 to 6,000 with a hydrophilic liquid base such as polyethylene glycol 400 to 600, which is known to be a more advanced method than the general soft capsule contents prescription and preparation method. Even in the case of a method of dissolution, the dissolution rate and dissolution rate may be better than the above method, but the effect cannot be greatly expected.

따라서 본 발명의 목적은 글리메피리드 0.1∼3.0 중량%에 친수성 기재인 폴리에틸렌글리콜 400∼600을 40∼75 중량%, 가용화제 및 용출촉진제 12∼44 중량%, 피마자유폴리옥실유도체(Polyoxyethylene Caster Oil Derivatives : 상품명 Cremophor RH40, Cremophor EL)에서 선택된 1종 이상의 안정화제 9∼20 중량% ; 구연산, 아세트산, 젖산에서 선택된 유기산 1∼3 중량%, 적량의 정제수, 농글리세린을 혼합 가용화시킨 내용액을 젤라틴 피막으로 제피시켜 제조된 글리메피리드를 가용화시킨 연질캅셀제를 제공하는 것이다.Therefore, an object of the present invention is 0.1 to 3.0% by weight of glymepiride 40 to 75% by weight of hydrophilic polyethylene glycol 400 to 600, 12 to 44% by weight solubilizer and elution accelerator, castor oil polyoxyl derivatives (Polyoxyethylene Caster Oil Derivatives: 9-20% by weight of one or more stabilizers selected from trade names Cremophor RH40, Cremophor EL); It is to provide a soft capsule agent solubilized glymepiride prepared by coating a solution of a solubilized solution of 1-3% by weight of an organic acid selected from citric acid, acetic acid and lactic acid, an appropriate amount of purified water and concentrated glycerin with a gelatin coating.

이때 상기 가용화제 및 용출촉진제는 라우로글리콜 90 (화학명: 프로필렌글리콜 모노라울레이트), 카프리욜 90 (화학명: 프로필렌글리콜 모노카프릴레이트), 프로필렌카보네이트, 트란스큐톨-P (화학명: 디에틸렌글리콜 모노에틸에테르)에서 선택된 1종 이상임을 특징으로 한다.In this case, the solubilizer and the dissolution accelerator are lauroglycol 90 (chemical name: propylene glycol monolaurate), capriol 90 (chemical name: propylene glycol monocaprylate), propylene carbonate, transcutol-P (chemical name: diethylene glycol mono Ethyl ether).

또한 본 발명은 가용화제 및 용출촉진제를 혼합 용해시킨 후 글리메피리드를 투입하여 약 60℃에서 교반 용해시키고, 약 40℃까지 냉각한 후, 안정화제, 친수성기제, 유기산, 정제수 등을 가하여 교반 용해시킨 후 실온으로 냉각하여 내용액을 균질화시킨 후 기포를 제거시켜 내용액을 제조하고 젤라틴 피막을 제피시킴을 특징으로 하는 글리메피리드를 가용화시킨 연질캅셀제의 제조방법을 제공하는 것이다.In the present invention, the solubilizing agent and the elution accelerator are mixed and dissolved, and glymepiride is added and stirred at about 60 ° C, and then cooled to about 40 ° C. After cooling to room temperature to homogenize the contents solution to remove the bubbles to prepare the contents solution to provide a method for producing a soft capsule solubilized glymepire characterized in that the gelatin coating film.
