도 1은, 본 발명의 제제예 1과 시판제제에 대한 염산슈도에페드린의 용출시험 결과를 나타낸 그래프이다.BRIEF DESCRIPTION OF THE DRAWINGS The graph which shows the dissolution test result of pseudoephedrine hydrochloride in the preparation example 1 of this invention and a commercial preparation.

본 발명은 염산슈도에페드린 및 염산세티리진을 함유한 제제로 속방성으로 염산슈도에페드린과 염산세티리진을 함유하고 따로 서방성의 염산슈도에페드린 약물층을 가진 약제학적 제제로서 단일 제제에 두 약물을 모두 포함하며, 서방성 약물층의 약물 방출이 위장관내 pH 변화와 무관하게 이루어지는 것을 그 특징으로 한다.The present invention is a pharmaceutical formulation containing pseudoephedrine hydrochloride and cetirizine hydrochloride, which contains immediate release of pseudoephedrine hydrochloride and cetirizine hydrochloride, and has a sustained-release suedephedrine hydrochloride drug layer, which includes both drugs in a single formulation. Drug release of the drug layer is characterized in that it is independent of pH changes in the gastrointestinal tract.

슈도에페드린(C10H15NO, MW=165.2)은 에페드린의 광학이성체로 에페드린과 유사한 작용을 하지만 진정작용은 상대적으로 작다. 슈도에페드린의 염으로는 염산슈도에페드린(C10H15NO?HCl, MW=201.7)과 황산슈도에페드린((C10H15NO)2?H2SO4, MW=428.5)이 의약품으로 사용되고 있다. 슈도에페드린 및 그 염은 SYMPATHOMIMETIC AGENT로 일반적으로 알러지성 비염에 기인하는 비울혈의 개선을 위해 항히스타민제와 함께 처방된다. 반감기는 5~7시간 정도이고 산성뇨에서 소실속도가 증가하여 반감기가 짧아진다. 또한 MAO 대사를 거치지 않고 대부분이 비대사체로, 일부 간대사를 받은 대사체와 함께 뇨중으로 배설된다. 하루 3-4회 경구 복용하는 제제가 일반적으로 장시간 유효농도의 유지가 가능한 항히스타민제는 통상의 방법으로 방출되고, 슈도에페드린 등의 비울혈완화제는 제어방출을 통해 1일 2회 내지는 1일 1회로 투여하는 것이 이상적이며 환자의 순응도에서 유리한 점이 있다.Pseudoephedrine (C10H15NO, MW = 165.2) is an optical isomer of ephedrine, which acts similar to ephedrine but has a relatively small sedation. As a salt of pseudoephedrine, pseudoephedrine hydrochloride (C10H15NO? HCl, MW = 201.7) and pseudoephedrine sulfate ((C10H15NO) 2? H2SO4, MW = 428.5) are used as medicines. Pseudoephedrine and its salts are SYMPATHOMIMETIC AGENT, which are usually prescribed with antihistamines for the improvement of nasal congestion due to allergic rhinitis. The half-life is about 5-7 hours and the half-life is shortened due to the increase of the disappearance rate in acidic urine. It is also excreted in urine together with metabolites that have undergone some hepatic metabolism, mostly without metabolism, without undergoing MAO metabolism. Antihistamines, which can be administered orally 3-4 times a day in general, can maintain their effective concentration for a long time, and are released in a conventional manner, and non-depressants such as pseudoephedrine are administered twice a day or once a day through controlled release. Ideally, there is an advantage in patient compliance.

염산세티리진(C21H25ClN2O3?2HCl, MW=461.8)은 피페라진계의 2세대 H1-리셉터 길항약으로서 진정작용이 작고, 항무스카린 효과가 미미하다. 경구로 투여할 경우 위장관내에서 신속하게 흡수되어 1시간 이내에 최대혈중농도에 도달하고, 반감기는 약 11시간이며 주로 요중으로 배설된다. 일반적으로 10mg을 1일 1회 또는 5mg을 1일 2회 투여한다.Cetirizine hydrochloride (C21H25ClN2O3-2HCl, MW = 461.8) is a piperazine-based second-generation H1-receptor antagonist with small sedation and minimal antimuscarinic effects. When taken orally, it is rapidly absorbed in the gastrointestinal tract, reaching a maximum blood concentration within 1 hour, with a half-life of about 11 hours, mainly excreted in the urine. Generally, 10 mg is administered once a day or 5 mg is administered twice a day.

백당으로 만든 구형입자에 염산슈도에페드린을 서방성약물층과 속방성약물층으로 나누어 코팅하여 펠렛을 제조하고, 따로 염산세티리진을 속붕해성 정제로 만든 다음 공캅셀에 충전한 제품이 상품명 씨러스캅셀 로 시판되고 있다. 그러나 이렇게 펠렛과 정제를 하나의 공캅셀에 충전하는 경우 특수한 충전기가 필요하고 제조공정이 길어지는 단점이 있다.The pellets are prepared by coating susceptible hydrochloride with suede hydrochloride into a sustained-release drug layer and a rapid-release drug layer, and separately preparing cetirizine hydrochloride as a fast disintegrating tablet and filling it into a blank capsule. It is commercially available. However, when the pellets and tablets are filled in one empty capsule, a special charger is required and the manufacturing process is long.

약물을 서방출시술은 크게 정제나 미세구체를 코팅하여 코팅막이 점차 파괴되며 약물이 방출되는 코팅형과 약물과 왁스 또는 고분자 물질을 함께 혼화하여 만 든 매트릭스형이 있다. 이중에서 미세구체에 약물을 입힌 다음 고분자 물질로 코팅하여 펠렛으로 만드는 방법은 Multiple unit으로 투여되므로 단일제제로 투여되는 경우에 비해 약물 방출을 정교하게 조절할 수 있고, 음식물의 영향이나 제제의 손상에 비교적 안정적인 장점이 있다. Sustained release of the drug is largely coated with tablets or microspheres, the coating film is gradually destroyed, there is a coating form in which the drug is released and a matrix made by mixing the drug and wax or polymer material together. Among them, the method of coating the microspheres and coating them with a polymer material to form pellets is administered in multiple units, so that the drug release can be precisely controlled compared to the case of a single agent, and relatively stable to food effects or damage to the preparation. There is an advantage.

약물이 약효를 발현하기 위해서는 유효혈중농도를 유지해야 하는데 이를 위해서는 하나의 제제에 서방출성 약물저장부 이외에 속방출성 약물저장부를 함께 설계하면 초기에 신속하게 유효혈중농도에 도달한 다음 지속적으로 유효혈중농도를 유지하는 장점이 있다. 특히 비충혈개선제나 알러지성 비염에 사용되는 항히스타민제와 같은 약물들은 신속한 증상 완화와 지속적인 증상 개선을 위해 위와 같은 제제로 설계할 필요성이 있다. 이와 같이 서방출성 약물저장부와 속방출성 약물저장부를 한 제제에 포함시키고자 하는 선행기술로는 다음과 같은 것들이 있다.In order for the drug to express its efficacy, it is necessary to maintain the effective blood concentration. For this purpose, if one drug is designed together with the slow-release drug storage in addition to the slow-release drug storage, the effective blood concentration is rapidly reached and then continuously There is an advantage of maintaining the concentration. In particular, drugs such as anti-hyperstatin and antihistamines used for allergic rhinitis need to be designed with such preparations for rapid symptom relief and continuous improvement of symptoms. As described above, there are the following prior arts for including the sustained release drug storage unit and the rapid release drug storage unit in one formulation.
