본 발명은 비타민 D 경구투여용 서방성 약제 조성물에 관한 것으로서, 더욱 상세하게는 저용량의 난용성 약물인 활성비타민 D 화합물을 유효성분으로 일정량 사용하고 기제로 히드록시프로필메칠셀룰로오스와 메칠셀룰로오스를 일정비율로 혼합하여 적정량 사용하여 서방화하고 이를 경구투여용으로 제제화하여 종래에 비해 유효성분인 활성비타민 D 화합물이 체내에서 서서히 방출되도록 함으로써 활성비타민 D 화합물의 지속적 방출과 일정농도의 유지가 가능하도록 하여 환자에게 투약횟 수를 감소시킬 수 있을 뿐만 아니라 약물적응성을 높일 수 있도록 한 비타민 D 경구투여용 서방성 약제 조성물에 관한 것이다.
The present invention relates to a sustained-release pharmaceutical composition for oral administration of vitamin D. More specifically, a certain amount of a low-dose poorly soluble drug, an active vitamin D compound, is used as an active ingredient, and a predetermined ratio of hydroxypropyl methyl cellulose and methyl cellulose is used as a base. By admixing with a suitable amount, it is sustained release and formulated for oral administration so that active vitamin D compound, which is an active ingredient, is released slowly in the body, so that active vitamin D compound can be continuously released and a certain concentration can be maintained. The present invention relates to a sustained-release pharmaceutical composition for oral administration of vitamin D, which can reduce the number of doses and increase drug adaptability.

약제학 분야에서 서방성 제제가 갖는 장점은 일반적으로 잘 알려져 있다. 이러한 장점 중에는 비교적 장기간 동안 약물의 혈중농도를 바람직한 수준으로 유지할 수 있어 종래 동일 목적을 얻기 위해서 필요한 투약횟수를 감소시킬 수 있을 뿐만 아니라, 결과적으로 환자들에 대한 약물적응성을 높일 수 있다는 것도 있다. The advantages of sustained release preparations in the pharmaceutical art are generally well known. Among these advantages, the blood concentration of the drug can be maintained at a desirable level for a relatively long period of time, which can reduce the number of administrations required to achieve the same purpose in the past, and consequently, can improve the drug adaptability to patients.

이러한 장점을 가진 서방성 제제는 친수성 고분자와 같은 서방성 담체가 연속상을 이루고 있는 매트릭스(matrix) 내에 약물이 분산되어 있는 매트릭스 제제가 사용되어지고 있다. 이러한 서방성 제제에서 약물의 용출속도는 친수성 고분자의 점도(Grade Viscosity; 2%, 20℃), 친수성 고분자와 약물의 함량비, 타정 압력, 정제의 모양 및 두께, 부형제, 약물의 입자도, 정제의 표면적 등에 의해 영향을 받으나, 주로 친수성 고분자의 점도 및 친수성 고분자와 약물의 함량비 및 약물의 물리, 화학적 성질에 의해 결정되어진다. Sustained release formulations having such advantages are used in which a matrix formulation in which drugs are dispersed in a matrix in which a sustained release carrier such as a hydrophilic polymer forms a continuous phase. In these sustained-release formulations, the dissolution rate of the drug was determined by the viscosity of the hydrophilic polymer (Grade Viscosity; 2%, 20 ° C), the content ratio of the hydrophilic polymer and drug, the tableting pressure, the shape and thickness of the tablet, the excipient, the particle size of the tablet, and the tablet. It is influenced by the surface area, etc., but mainly determined by the viscosity of the hydrophilic polymer, the content ratio of the hydrophilic polymer and the drug, and the physical and chemical properties of the drug.

이러한 서방성 제제의 공지 기술로는 다음과 같은 것이 있다.Known techniques for such sustained release preparations include the following.

Shah, A. 는 히드록시프로필메칠셀룰로오스(hydroxypropylmethylcellulose, HPMC), 메칠셀룰로오스(methylcellulose, MC), 카르복시메칠셀룰로오스나트륨(Na-carboxymethylcellulose, Na-CMC) 등을 사용하여 이브프로펜(ibuprofen), 디클로페낙(diclofenac), 인도메타신(indomethacin) 등을 서방형 제제로 제조하고[유럽특허 제 227,814호], Sheth P.R. 등은 HPMC, 히드록시프로필셀룰로오스(hydroxypropylcellulose, HPC) 등을 사용하여 아세틸살리실산(acetylsalicylic acid)을 서방형 제제로 제조하였다[미국특허 제 4,126,672호]. 또한 Devi 등은 옥소프레놀롤(Oxoprenolol)에 HPMC와 Na-CMC를 1:0.4:1.6의 중량비로 혼합하여 매트릭스형의 정제를 제조하여 옥소프레놀롤에 대한 서방형 제제를 제조하였다[Pharm.Res.,6(4), p313∼317, Apr.1989].Shah, A. uses hydroxypropylmethylcellulose (HPMC), methylcellulose (MC), sodium carboxymethylcellulose (Na-carboxymethylcellulose (Na-CMC), etc. diclofenac), indomethacin (indomethacin) and the like as a sustained release formulation (European Patent No. 227,814), Sheth PR Et al. Prepared acetylsalicylic acid as a sustained release formulation using HPMC, hydroxypropylcellulose (HPC) and the like (US Pat. No. 4,126,672). In addition, Devi et al. Prepared a matrix-type tablet by mixing HPMC and Na-CMC in a weight ratio of 1: 0.4: 1.6 in oxoprenolol (Oxoprenolol) to prepare a sustained-release formulation for oxoprenolol [Pharm. Res. , 6 (4), p313-317, Apr. 1989].

서방성 제제설계에 있어서 발생될 수 있는 두가지의 문제점으로 첫번째는 초기 약물의 과다방출(Burst-out 또는 dose-dumpping)로 인해 서방기능이 저하되는 현상과 두번째는 목적하는 시간에 약물방출이 지연되어 적절한 약물방출을 할 수 없는 현상(Lag-phase)이 있다. 이러한 문제점 때문에 유효성분의 특징 등을 고려하여 제제설계시 서방성 제제의 기제를 선택하는 것은 매우 중요하다.
Two problems that can occur in the design of sustained-release formulations are: first, the slow release of the drug due to over-release of the initial drug (Burst-out or dose-dumpping) and second, delayed release of the drug at the desired time. There is a lag-phase incapable of adequate drug release. Because of this problem, it is very important to select the base of the sustained release formulation in the design of the formulation in consideration of the characteristics of the active ingredient.

한편, 약물로 지용성 비타민을 사용하고, 매트릭스기제로 친수성 고분자를 사용하여 경구형 서방성 제제로 제조하는 기술이 다수 공지되어 있으나, 지용성 비타민을 상기 공지기술로 서방성 제제로 제조할 경우 유효성분이 장시간 동안 일정한 속도로 용출되지 않아 1일 1회 복용으로 충분한 치료효과를 나타낼 수 없는 문제가 있어 왔다. 특히, 상기 지용성 비타민 중 본 발명의 유효성분인 활성비타민 D 화합물은 일반적으로 속방성 연질 캅셀로 제제화되어 1일 2회 이상 복용하는 약제로 사용되고 있다. 이러한 활성비타민 D 화합물은 일반적으로 골대사질환 치료제로 사용되고 있어 장기간 지속적으로 복용하여야 하기 때문에 환자에게 복용시 편이성은 그 약효 못지 않게 중요한 요소가 되고 있다.
On the other hand, a number of techniques for preparing oral sustained-release preparations using fat-soluble vitamins as drugs and using hydrophilic polymers as matrix bases are known. There has been a problem that does not elute at a constant rate during a day does not exhibit sufficient therapeutic effect by taking once a day. In particular, the active vitamin D compound which is an active ingredient of the present invention among the fat-soluble vitamins is generally formulated as a rapid-release soft capsule and used as a medicament to be taken twice or more a day. Since the active vitamin D compound is generally used as a drug for treating bone metabolic diseases, it has to be taken continuously for a long time, and thus the ease of taking it to patients has become an important factor as well as its efficacy.

이에, 본 발명에서는 저용량의 난용성 약물인 활성비타민 D 화합물을 유효성분으로 일정량 사용하고 기제로 히드록시프로필메칠셀룰로오스와 메칠셀룰로오스를 일정비율로 혼합하여 적정량 사용하여 서방화하고 이를 경구투여용으로 제제화시킴으로써 본 발명을 완성하였다.Therefore, in the present invention, a small amount of the active vitamin D compound, which is a poorly water-soluble drug, is used as an active ingredient, and hydroxypropyl methyl cellulose and methyl cellulose are mixed at a predetermined ratio as a base, so that they are sustained by using an appropriate amount and formulated for oral administration. This invention was completed by making it.

따라서, 본 발명은 유효성분인 활성비타민 D 화합물이 체내에서 서서히 방출되도록 함으로써 활성비타민 D 화합물의 지속적 방출과 일정농도의 유지가 가능하도록 하여 환자에게 투약횟수를 감소시킬 수 있을 뿐만 아니라 약물적응성을 높일 수 있도록 한 비타민 D 경구투여용 서방성 약제 조성물을 제공하는데 그 목적이 있다.
Accordingly, the present invention allows the active vitamin D compound, which is an active ingredient, to be slowly released in the body, thereby enabling sustained release of the active vitamin D compound and maintaining a constant concentration, thereby reducing the number of doses to the patient and improving drug adaptability. The purpose is to provide a sustained release pharmaceutical composition for oral administration of vitamin D.

본 발명은 유효성분으로 활성비타민 D 화합물 0.00025 ∼ 1 중량%, 기제로서 메칠셀룰로오스와 히드록시프로필메칠셀룰로오스의 혼합물 10 ∼ 60 중량% 및 약제학적 첨가제 10 ∼ 89 중량%가 포함된 비타민 D 경구투여용 서방성 약제 조성물을 그 특징으로 한다.The present invention is an active ingredient for vitamin D oral administration containing 0.00025 ~ 1% by weight of active vitamin D compound, 10 to 60% by weight of a mixture of methyl cellulose and hydroxypropyl methyl cellulose and 10 to 89% by weight of pharmaceutical additives as a base It is characterized by a sustained release pharmaceutical composition.

이와 같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.

본 발명은 비타민 D 경구투여용 서방성 약제 조성물에 관한 것으로서, 저용량의 난용성 활성비타민 D 화합물과 특정 기제를 일정함량으로 조절하여 서방화시 키고 이를 경구투여용으로 제제화하여 장기간 동안 약물의 혈중농도를 바람직한 수준으로 유지할 수 있어 종래 동일 목적을 얻기 위해서 필요한 투약횟수를 감소시킬 수 있을 뿐만 아니라, 결과적으로 환자들에 대한 약물적응성을 높일 수 있는 장점을 가진 비타민 D 경구투여용 서방성 약제 조성물에 관한 것이다.The present invention relates to a sustained-release pharmaceutical composition for oral administration of vitamin D, wherein a low dose of a poorly soluble active vitamin D compound and a specific base is controlled to a sustained amount and is formulated for oral administration so that the blood concentration of the drug for a long period of time. It can be maintained at a desirable level can not only reduce the number of doses required to achieve the same purpose in the past, but as a result of the sustained-release pharmaceutical composition for oral administration of vitamin D having the advantage of increasing the drug adaptability to patients will be.

본 발명의 약제 조성물의 조성성분에 따라 더욱 상세히 설명하면 다음과 같다. According to the composition of the pharmaceutical composition of the present invention will be described in more detail as follows.

먼저, 유효성분으로 활성비타민 D 화합물을 사용할 수 있다. 상기 활성비타민 D 화합물은 저용량의 난용성 약물로서 전체 약제 조성물 중에 0.00025 ∼ 1 중량% 함유하는 것이 바람직하며, 만일 그 함유량이 0.00025 중량% 미만이면 원하는 약리활성을 나타낼 수 없으며, 1 중량%를 초과하면 활성비타민의 부작용인 고칼슘혈증 또는 고칼슘뇨증 등의 부작용이 초래된다.First, an active vitamin D compound can be used as an active ingredient. The active vitamin D compound is a low dose, poorly soluble drug, it is preferable to contain 0.00025 to 1% by weight in the total pharmaceutical composition, if the content is less than 0.00025% by weight can not exhibit the desired pharmacological activity, if it exceeds 1% by weight Side effects such as hypercalcemia or hypercalciuria, which are side effects of active vitamins, are caused.

상기 활성비타민 D 화합물로는 1α,25-디하이드록시비타민 D3, 1α,24-디하이드록시비타민 D3, 1α-하이드록시비타민 D3, 1α,25-디하이드록시비타민 D2 , 1α,24-디하이드록시비타민 D2, 1α-하이드록시비타민 D2, 1α,25-디하이드록시비타민 D4, 1α,24-디하이드록시비타민 D4 또는 1α-하이드록시비타민 D4 등을 사용할 수 있으며, 바람직하게는 1일 최대투여용량이 0.5 ㎍ 이하인 1α,25-디하이드록시비타민 D3가 좋다.
To the active vitamin D compound is 1α, 25- dihydroxy-vitamin D 3, 1α, 24- dihydroxy-vitamin D 3, 1α- hydroxy-vitamin D 3, 1α, 25- dihydroxy vitamin D 2, 1α, be used as the 24-dihydroxy vitamin D 2, 1α- hydroxy-vitamin D 2, 1α, 25- di hydroxy vitamin D 4, 1α, 24-dihydroxy vitamin D 4 or 1α- hydroxy-vitamin D 4 Preferably, 1α, 25-dihydroxyvitamin D 3 with a maximum daily dose of 0.5 μg or less is preferred.

본 발명에 따른 약제 조성물을 서방화시키는데 가장 중요한 성분인 서방화 담체인 기제로는 메칠셀룰로오스와 히드록시프로필메칠셀룰로오스를 혼합사용하도록 하는 바, 전체 약제 조성물 중에 10 ∼ 60 중량% 함유하는 것이 바람직하다. 만일, 기제로서 메칠셀룰로오스와 히드록시프로필메칠셀룰로오스 혼합물의 함유량이 10 중량% 미만이면 고분자 혼합물의 점도가 떨어져 약물방출 기구인 겔층이 소화액 등에 의하여 침식되어 제제의 서방기능이 저하되거나 겔이 빠른 시간 내에 소멸됨으로 유효성분의 용출속도가 너무 빨라 약물과다방출현상이 발생하게 되며, 60 중량%를 초과하면 고분자 겔층을 통한 약물확산이 저하되어 용출율이 떨어져 충분한 용출이 되지 않아 래그-페이스(lag-phase) 현상이 야기되어 기대하는 치료가 충분히 이루어지지 않을 수 있다. 상기 메칠셀룰로오스와 히드록시프로필메칠셀룰로오스의 혼합물은 수용성 매질과 접촉하여 약물방출 기구인 겔을 형성하여 서방화 담체 역할을 하며, 본 발명에서는 점도가 각각 500 ∼ 4,000 cps인 것을 사용하는 것이 바람직하며, 더욱 바람직하게는 메칠셀룰로오스와 히드록시프로필메칠셀룰로오스 점도가 각각 4,000 cps인 것이 좋다. 만일 메칠셀룰로오스와 히드록시프로필메칠셀룰로오스의 점도가 500 cps 미만이면 제제의 서방기능이 저하되거나 유효성분의 용출율이 일정양으로 지속적이지 못한 문제가 있고, 4,000 cps를 초과하면 고분자 겔층을 통한 약물확산이 저하되어 용출율이 떨어져 충분한 용출이 되지 않는 문제가 있다.As the base of the sustained release carrier which is the most important component for sustaining the pharmaceutical composition according to the present invention, the mixture of methyl cellulose and hydroxypropyl methyl cellulose is used. It is preferable to contain 10 to 60% by weight of the total pharmaceutical composition. . If the content of the mixture of methyl cellulose and hydroxypropyl methyl cellulose is less than 10% by weight as a base, the viscosity of the polymer mixture is lowered, and the gel layer, which is a drug release mechanism, is eroded by the digestive fluid. Excessive dissolution rate of the active ingredient due to extinction causes excessive drug release, and when it exceeds 60% by weight, drug diffusion through the polymer gel layer is lowered, and the dissolution rate is lowered. Symptoms may occur and the expected treatment may not be sufficient. The mixture of methyl cellulose and hydroxypropyl methyl cellulose forms a gel as a drug release mechanism in contact with a water-soluble medium to serve as a sustained release carrier, and in the present invention, it is preferable to use those having a viscosity of 500 to 4,000 cps, respectively. More preferably, the methyl cellulose and the hydroxypropyl methyl cellulose viscosity are each 4,000 cps. If the viscosity of the methyl cellulose and hydroxypropyl methyl cellulose is less than 500 cps, there is a problem that the sustained-release function of the formulation is lowered or the dissolution rate of the active ingredient is not sustained in a certain amount, and if the viscosity exceeds 4,000 cps, drug diffusion through the polymer gel layer There is a problem that the elution rate is lowered, so that the elution rate is not sufficient.

또한, 상기 메칠셀룰로오스와 히드록시프로필메칠셀룰로오스 혼합물의 혼합비는 1:1 ∼ 1:10 중량비가 바람직하며, 더욱 바람직하게는 1:2 중량비가 좋다. 만일 혼합비가 1:1 중량비 미만이면 고분자 혼합물의 점도가 떨어져 약물방출 기구인 겔층이 소화액 등에 의하여 빠르게 침식되어 장시간 동안 제제의 서방기능이 저하되거나 겔이 빠른 시간 내에 소멸되고, 1:10 중량비를 초과하면 고분자 혼합물의 점도가 높아져 팽윤된 겔층을 통한 유효성분의 용출속도가 저하되어 충분한 용출이 되지 않아 치료가 충분히 이루어지지 않거나 고분자 혼합물의 고점도의 영향에 의해 약물방출의 재현성과 분석상의 회수율에 문제가 있다.In addition, the mixing ratio of the methyl cellulose and hydroxypropyl methyl cellulose mixture is preferably 1: 1 to 1:10 by weight, more preferably 1: 2 by weight. If the mixing ratio is less than 1: 1 weight ratio, the viscosity of the polymer mixture is lowered, and the gel layer, which is a drug release mechanism, is rapidly eroded by the digestive fluid, so that the sustained-release function of the formulation is degraded for a long time, or the gel disappears quickly, and exceeds 1:10 weight ratio. When the viscosity of the polymer mixture increases, the dissolution rate of the active ingredient through the swollen gel layer decreases, so that the dissolution is not sufficient, and the treatment is not sufficiently performed or the reproducibility of the drug release and the analytical recovery rate are affected by the high viscosity of the polymer mixture. have.

한편, 약물의 서방성 제제를 제조하는데 있어 서방화 담체로 친수성 고분자를 적용하여 왔으나, 본 발명의 비타민 D 경구투여 제제에 적용되어서는 비타민 D와 부형제간의 상호작용에 따른 안정성이 문제가 되어왔다. 따라서, 본 발명에서는 공지의 친수성 고분자인 메칠셀룰로오스, 히드록시프로필셀룰로오스, 히드록시프로필메칠셀룰로오스, 카르복시메칠셀룰로오스나트륨, 트라가칸, 잔탄 검, 아라비아 검, 카보머, 유드라지트 등에서도 가장 주성분인 비타민 D와 상호작용이 없는 특성을 가지는 메칠셀룰로오스와 히드록시프로필메칠셀룰로오스를 서방화 담체로 선택하게 되었고, 또한 상기한 두 고분자를 1:1 ∼ 1:10 중량비로 혼합 사용함으로써 상기한 문제를 해결함과 동시에 본제제의 목적대로 장시간에 걸친 지속적으로 용출되는 서방성 효과를 얻을 수 있었다.
On the other hand, the hydrophilic polymer has been applied as a sustained release carrier in the preparation of a sustained-release preparation of the drug, the stability of the interaction between the vitamin D and the excipient has been a problem when applied to the vitamin D oral dosage formulation of the present invention. Therefore, in the present invention, methylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, sodium carboxymethylcellulose, tragacan, xanthan gum, gum arabic, carbomer, eudragit, etc., which are known hydrophilic polymers, Methyl cellulose and hydroxypropyl methyl cellulose, which have no interaction with vitamin D, were selected as a sustained release carrier, and the above problems were solved by mixing the two polymers in a 1: 1 to 1:10 weight ratio. At the same time, the sustained-release effect of eluting for a long time according to the purpose of the present agent was obtained.

또한, 본 발명에 따른 약제 조성물은 상기한 비타민 D 유효성분과 메칠셀룰로오스와 히드록시프로필메칠셀룰로오스의 혼합물로 이루어진 서방성 담체 이외에 일반적으로 경구투여용 고형제제에 허용되는 약제학적 첨가제, 즉 중성의 희석담 체, 결합제, 항산화제 및 활택제 등을 함유하는 바, 이들 첨가제는 전체 약제 조성물 중에 10 ∼ 89 중량% 함유하는 것이 바람직하다.In addition, the pharmaceutical composition according to the present invention, in addition to the sustained-release carrier consisting of a mixture of the above-mentioned vitamin D active ingredient, methyl cellulose and hydroxypropyl methyl cellulose, is generally acceptable pharmaceutical additives, that is, neutral diluents. Bars, binders, antioxidants, glidants and the like are included, and these additives are preferably contained in 10 to 89% by weight in the total pharmaceutical composition.
