Description
본 발명은 약물 코팅의 기술 분야, 특히 장용성 필름 코팅 조성물(enteric soluble film coating composition)에 관한 것이다.The present invention relates to the technical field of drug coating, particularly enteric soluble film coating composition.
필름 코팅 기술은 1940년대에 개발된 신기술이다. 제약 산업이 발전함에 따라 필름 코팅 기술은 점점 더 발전하고 성장하였으며 점차 전통적인 당의 코팅(sugar coating) 공정을 대체하였다.Film coating technology is a new technology developed in the 1940s. As the pharmaceutical industry develops, film coating technology develops and grows, gradually replacing the traditional sugar coating process.
필름 코팅은 코어 재료, 예를 들면, 분말, 입자, 펠렛 또는 정제의 표면에 필름 층을 코팅하는 것을 지칭한다. 코팅 필름은 습기를 방지하고 외관을 향상시키며 식별을 용이하게 하고 기계적 힘을 방지하며 악취를 은폐하고 착색하며 위장 반응을 감소시키고 약물 활성 성분의 방출 성능을 향상시킬 수 있다. 전통적인 당의 코팅에 비해 필름 코팅 기술은 생산 주기가 짧고 재료가 적게 들며 내습성이 강하다는 특징을 갖는다.Film coating refers to coating a film layer on the surface of a core material, such as a powder, particle, pellet or tablet. The coating film can prevent moisture, improve appearance, facilitate identification, prevent mechanical force, conceal bad odor, color, reduce gastrointestinal reaction, and improve the release performance of drug active ingredients. Compared to traditional sugar coating, film coating technology has the characteristics of a short production cycle, low material requirements, and strong moisture resistance.
기존의 장용성 필름 코팅 예비혼합물은 일반적으로 포괄적인 성능이 좋지 않다.Conventional enteric film coating premixes generally have poor overall performance.

Dissolution rate test: According to the first method of the Pharmacopoeia, the rotation speed of the rotating basket is set to 120 r/min and the dissolution medium is artificial gastric fluid and artificial intestinal fluid for dissolution test. Sample 5 ml of microporous membrane for filtration within 45 minutes. The filtrate is measured according to literature and compared to a sample membrane coated tablet to calculate the dissolution rate of the membrane coated tablet within 45 minutes.
2. 내열성 시험: 실시예 2 및 비교실시예에서 제조한 필름 코팅 정제의 저온 및 고온에서의 외관에 미치는 영향을 연구한다.2. Heat resistance test: Study the effect on the appearance of the film-coated tablets prepared in Example 2 and Comparative Examples at low and high temperatures.
3. 안정성 시험: 실시예 2 및 비교실시예 2에서 제조된 약물 필름 코팅의 안정성을 시험한다. 코팅 전 정제 코어의 방출량을 100% 기준으로 한다. 두 그룹은 동일한 작동 매개변수로 동일한 뱃치의 정제 코어를 코팅하였다. 6개월간의 가속 시험 후, 정제 코어는 1개월마다 시험하였다. 데이터는 하기 표에 제시하였다.3. Stability test: The stability of the drug film coating prepared in Example 2 and Comparative Example 2 is tested. The emission amount of the tablet core before coating is based on 100%. Both groups coated the same batch of tablet cores with identical operating parameters. After 6 months of accelerated testing, the tablet cores were tested every month. The data is presented in the table below.
본 발명에 의해 제조된 약물 필름 코팅은 양호한 안정성을 가짐을 실험 결과로부터 알 수 있다. 6개월의 저장 기간 후에 코팅 내의 코어에 있는 활성 성분은 산화 또는 수분 흡수가 비교적 적어서 100%로부터 81.7%로 감소한다.It can be seen from the experimental results that the drug film coating prepared by the present invention has good stability. After a storage period of 6 months, the active ingredient in the core within the coating decreases from 100% to 81.7% with relatively little oxidation or moisture absorption.
위의 실시예는 본 발명의 여러 양태를 나타낸 것일 뿐이며, 그 설명이 보다 구체적이고 상세하지만, 발명 특허의 범위를 한정하는 것으로 이해되어서는 안 된다. 당업자는 본 발명의 보호 범위에 속하는 본 발명의 개념을 벗어나지 않으면서 여러 변형 및 향상이 이루어질 수 있음을 주목해야 한다. 그러므로, 본 발명의 특허의 보호 범위는 첨부된 청구범위의 적용을 받으며 설명 및 첨부된 도면을 사용하여 청구범위의 내용을 설명할 수 있다.The above examples only illustrate various aspects of the present invention, and although the description is more specific and detailed, they should not be understood as limiting the scope of the invention patent. Those skilled in the art should note that various modifications and improvements can be made without departing from the concept of the present invention, which falls within the protection scope of the present invention. Therefore, the scope of protection of the patent for the present invention is subject to the appended claims, and the content of the claims can be explained using the description and accompanying drawings.
