전 세계적으로 당뇨병은 성인 사망의 중요한 원인의 하나가 되고 있고, 비만 인구의 증가에 따라 당뇨환자의 수도 급격하게 늘어나고 있으며, 이는 과도한 글루코스 생성 및 말초 인슐린 저항성으로 인한 과혈당증을 특징으로 한다.Diabetes is one of the leading causes of adult death worldwide, and the number of diabetic patients is increasing rapidly with the increase in the obese population, characterized by hyperglycemia due to excessive glucose production and peripheral insulin resistance.
혈장 글루코스는 통상적으로 신장 사구체에서 여과되고, 근위 세관에서 능동적으로 재흡수된다. SGLT-2는 이 부위에서 글루코스의 재흡수에 관여하는 주요 수송자로 판단된다.Plasma glucose is usually filtered in the renal glomeruli and actively resorbed in the proximal tubule. SGLT-2 is believed to be the major transporter involved in the resorption of glucose at this site.
따라서 당뇨병 환자에서 SGLT-2(Sodium-Glucose linked Transporter 2)의 선택적 억제는 유의한 위장 부작용 없이 소변 중의 글루코스 배출을 증대시켜 인슐린 민감성을 개선시키고 당뇨병 합병증의 발병을 지연시킴으로써 혈장 글루코스를 정상화시킬 수 있다. 이에, SGLT-2 억제제는 당뇨병, 당뇨병 관련 질환 및 당뇨병성 합병증의 예방 또는 치료제로 주목 받고 있다. Thus, selective inhibition of SGLT-2 (Sodium-Glucose linked Transporter 2) in diabetics can normalize plasma glucose by increasing glucose excretion in urine without significant gastrointestinal side effects, improving insulin sensitivity and delaying the onset of diabetic complications. . Therefore, SGLT-2 inhibitors are attracting attention as a prophylactic or therapeutic agent for diabetes, diabetes-related diseases and diabetic complications.
SGLT-2 억제제 중 하나인 다파글리플로진(Dapagliflozin, (2S,3R,4R,5S,6R)-2-[4-클로로-3-(4-에톡시벤질)페닐]-6-(히드록시메틸)테트라히드로-2H-피란-3,4,5-트리올)은 하기 화학식 1의 화합물로서, 미국특허 제6,515,117호에 개시되어 있다.Dapagliflozin, (2S, 3R, 4R, 5S, 6R) -2- [4-chloro-3- (4-ethoxybenzyl) phenyl] -6- (hydr, one of the SGLT-2 inhibitors Oxymethyl) tetrahydro-2H-pyran-3,4,5-triol) is a compound represented by the following formula (1) and is disclosed in US Pat. No. 6,515,117.

당뇨병은 만성질환으로서 그 병태가 복잡하기 때문에, 병의 증상이 다종의 합병증을 동반하면서 진행되는 경우가 많으며 질환의 특성상 장기간 약물의 복용이 요구된다. 따라서 개개의 환자의 그때의 병상에 가장 적합한 약제를 선택할 필요가 있으며, 개개의 약제를 단독으로 사용하는 경우 증상에 따라 충분한 효과가 얻어지지 않는 경우도 있고, 또한 투여량의 증대나 투여의 장기화에 따른 부작용의 발현 등 여러 가지 문제로 인해 임상 현장에서는 약물의 선택이 곤란한 경우가 많다.Diabetes is a chronic disease, and its condition is complicated, so the symptoms of the disease often progress with various complications, and the nature of the disease requires long-term administration of the drug. Therefore, it is necessary to select the most appropriate drug at the time of the individual patient, and when the individual drugs are used alone, sufficient effects may not be obtained depending on the symptoms. Due to various problems such as the appearance of side effects, it is often difficult to select a drug in the clinical field.
따라서 당뇨병, 당뇨병 관련 질환 및 당뇨병성 합병증의 예방 또는 치료와 관련하여 한 가지 약물을 단독으로 투여하기 보다는 상이한 기전을 가진 2 이상의 약물을 병용 투여하는 방안이 제시되고 있다.Therefore, in connection with the prevention or treatment of diabetes mellitus, diabetes-related diseases and diabetic complications, a method of co-administering two or more drugs having different mechanisms rather than one drug alone has been proposed.
그러나, 2 이상의 약물을 혼합한 복합 제제를 제조할 시, 2 이상의 약물의 상호작용 등으로 인해 안정성에 문제가 생기거나 또는 각 성분이 단일 제제에서 나타내는 용출율보다 더 낮은 용출율을 나타내는 등 용출율이 저하되는 문제점이 발생할 수 있다.However, when preparing a combination formulation of two or more drugs, the dissolution rate is lowered due to the problem of stability due to the interaction of two or more drugs, or the dissolution rate of each component is lower than that of the single agent. Problems may arise.
