Description

오메프라졸 경구제제의 제조방법 {Manufacturing Method of Omeprazole oral dosage forms}Manufacturing method of omeprazole oral preparations {Manufacturing Method of Omeprazole oral dosage forms}

본 발명은 유효한 위산 분비 억제제인 오메프라졸(omeprazole) 또는 란소프라졸(lansoprazole) 및 그의 약리학적으로 활성을 나타내는 염류를 함유하는 안정한 신규의 경구제제의 제조방법에 관한 것으로, 이 제제를 사용하여 위산분비를 억제하여 위장관 세포를 궤양으로부터 효과적으로 보호하기 위한 것이다. The present invention relates to a method for preparing a stable oral preparation containing an effective gastric acid secretion inhibitor omeprazole or lansoprazole and its pharmacologically active salts. It is to effectively protect the gastrointestinal cells from ulcers.

특히, 오메프라졸 및 그 염류는 산성 및 중성에서 경시적으로 분해 및 변형되기 쉬우며 보통 pH 4이하에서의 반감기는 10분 이내이며 또한 중성 pH에서도 약 14시간 정도에 지나지 않는 매우 불안정한 화합물의 일종이다. 그러나 pH값이 알카리성(pH 10)일 경우에는 다소 안정하여 약 300여일 정도인 것으로 알려져 있다. 오메프라졸의 분해는 산 매질에 의해 급격하게 분해되므로 제제화에 많은 문제점으로 남아있다. 또한 오메프라졸의 안정성은 습기와 유기용매에 의해서도 영향을 받는다.In particular, omeprazole and its salts are susceptible to degradation and modification over time in acid and neutral, and have a half-life of less than 10 minutes at pH 4 or less, and are also very unstable compounds of about 14 hours at neutral pH. However, when the pH value is alkaline (pH 10), it is known to be somewhat stable and about 300 days. The degradation of omeprazole remains a major problem in formulation because it is rapidly degraded by the acid medium. The stability of omeprazole is also affected by moisture and organic solvents.

오메프라졸을 함유한 안정한 제제는 현재까지 많은 제조방법이 개발되어 사용되고 있으나 보다 향상된 안정화 방법의 개발이 요구되고 있다. 현재 개발되어 있는 오메프라졸 함유 제제의 이러한 문제점을 해결하고, 혁신적으로 공정시간을 단축할 수 있는 제조방법이 본 발명에 의해서 가능하였다.Stable formulations containing omeprazole have been developed and used to date, but there is a need for further development of stabilization methods. The present invention has been made possible to solve this problem of the currently developed omeprazole-containing formulations and to innovatively shorten the process time.

본 발명은 상기한 오메프라졸 또는 란소프라졸을 함유한 보다 안정한 제제를 제공함으로써 치료효과를 극대화한 것으로, 본 발명의 목적은 상기한 제제의 경구 투여시 위산에 의한 활성의 소실을 차단하고 소장에서의 약물 흡수를 용이하게 할 수 있는 약제학적으로 안정한 신규의 경구제제의 제조방법을 제공하고자 하는 것이다.        The present invention maximizes the therapeutic effect by providing a more stable formulation containing the omeprazole or lansoprazole as described above, an object of the present invention is to block the loss of activity by gastric acid during oral administration of the formulation and to absorb the drug in the small intestine It is to provide a method for preparing a pharmaceutically stable new oral formulation that can facilitate.

본 발명은 유효활성물질인 오메프라졸 또는 란소프라졸을 적당한 용매를 사용하여 용해 또는 분산시킨 후 각종 시드(seed)를 사용하여 과립화 및 구형화를 실현하여 상기의 목적을 달성할 수 있었는바, 선행 기술에 의한 유사제제의 제조시 낮은 수율을 극복하여 원료의 손실을 최소화할 수 있다. 또한 본 발명은 적당한 부형제 및 용제를 첨가하여 용해를 용이하게 하였다. 아울러 본 발명은 과립화 및 구형화한 약물을 적당한 기제를 사용하여 보호코팅 및 장용코팅을 실시하는 기술로서 그 공정이 매우 단순해 질 수 있다.The present invention was able to achieve the above object by dissolving or dispersing an active active material omeprazole or lansoprazole using a suitable solvent and then realizing granulation and spheronization using various seeds. It is possible to minimize the loss of raw materials by overcoming low yields in the preparation of analogous preparations. The present invention also facilitated dissolution by adding suitable excipients and solvents. In addition, the present invention is a technique for carrying out protective coating and enteric coating of granulated and spherical drugs using a suitable base, the process can be very simple.

본 발명에서는 오메프라졸을 물과 알코올 또는 물만을 사용하여 용해 또는 분산시켜 사용하는 것으로 그 혼합 비율을 달리하여 용해도를 조절할 수 있다. 본 발명에서는 알코올과 물의 비율을 1:1, 0.8:1, 0.6:1, 0.5:1, 0.4:1, 0.2:1, 0:1등 다양하게 사용하였으며 알코올의 양이 많아질수록 용해도는 약간씩 증가하였으나 안정성이 부족하였는바, 탈크를 안정화부형제로 추가함유토록 설계하여 제제의 안정성을 확보할 수 있었다.          In the present invention, by using omeprazole dissolved or dispersed using only water and alcohol or water, solubility can be adjusted by varying the mixing ratio. In the present invention, the ratio of alcohol and water was used in various ways such as 1: 1, 0.8: 1, 0.6: 1, 0.5: 1, 0.4: 1, 0.2: 1, 0: 1, and solubility was slightly increased as the amount of alcohol increased. Although it increased gradually, the stability was insufficient, so that the talc was added as a stabilizing excipient to ensure the stability of the formulation.

한편, 탈크는 천연의 함수규산마그네슘으로 백색∼회백색의 미세한 결정성 가루이며 물, 에탄올 또는 에텔에 거의 녹지 않으므로 활성물질의 역가에 영향을 미치지 않는 중성의 활택성을 가진 부형제로 알려져 있다.           On the other hand, talc is a natural hydrous magnesium silicate and is white to gray fine crystalline powder, which is hardly soluble in water, ethanol or ether, and is known as an excipient with neutral glidability that does not affect the titer of the active substance.

본 발명은 다음의 공정들로 이루어진다.The present invention consists of the following processes.

전분 및 설탕, 또는 설탕만을 사용하여 직경 0.2∼0.7밀리미터의 입자도를 가지는 불활성 미세과립을 제조하고, 오메프라졸 또는 란소프라졸과 히드록시프로필메칠셀룰로오스, 또는 히드록시프로필셀룰로오스 및 그 유도체중에서 선택한 결합제를 정제수,아세톤,에탄올의 혼합용매에 용해 또는 분산시킨 다음, 이 용액을 상기의 미세과립에 탈크와 함께 조합시켜, 오메프라졸 또는 란소프라졸이 조합된 과립을 제조한후 필름코팅기제로 보호코팅을 실시하고 장용성코팅기제와 가소제로 장용코팅을 실시하여 입자도가 직경 0.3∼2.5 밀리미터 정도의 크기를 가지는 장용성펠렛을 제조하는 것을 특징으로 하며, 그람당 유효활성물질의 역가를 80∼100 밀리그람으로 만들 수 있었다.Inert microgranules having a particle size of 0.2 to 0.7 mm in diameter are prepared using only starch and sugar or sugar, and a binder selected from omeprazole or lansoprazole and hydroxypropyl methyl cellulose, or hydroxypropyl cellulose and its derivatives is purified water, acetone. After dissolving or dispersing in a mixed solvent of ethanol, the solution is combined with talc in the fine granules to prepare granules in which omeprazole or lansoprazole is combined, followed by protective coating with a film coating base, and an enteric coating base and a plasticizer. The enteric coating was performed to prepare an enteric pellet having a particle size of about 0.3 to 2.5 millimeters in diameter, and the potency of the active substance per gram was 80 to 100 milligrams.

본 발명에 있어서, 불할성 미세과립은 구형과립의 형태가 바람직하고, 장용성코팅기제로는 프탈산히드록시 프로필메칠셀룰로오스, 히드록시프로필메칠셀룰로오스 아세테이트숙시네이트 또는 메타아크릴산 공중합체중에서 선택하며, 가소제로는 폴리에칠렌 글리콜 6000이나 트리아세틴, 트리에칠시트레이트중에서 선택사용한다.In the present invention, the insoluble microgranules are preferably in the form of spherical granules, and the enteric coating base is selected from hydroxy propyl methyl cellulose, hydroxypropyl methyl cellulose acetate succinate or methacrylic acid copolymer, and as a plasticizer, polystyrene is used. Choose from Glycol 6000, Triacetin or Triethyl Citrate.

본 발명의 오메프라졸 경구제제는 오메프라졸 또는 란소프라졸을 유효성분으로 함유한 장용코팅 미세과립을 경질젤라틴 캅셀에 일정량씩 충전하여 복용을 편리하게 한 제제이다.Omeprazole oral preparations of the present invention are convenient formulations by filling a fixed amount of hard gelatin capsules with enteric-coated microgranules containing omeprazole or lansoprazole as active ingredients.
