Dissolution tester Pharma test GembH (Germany) Pharma test GembH (Germany)

용출 시험의 정의 용출 시험이라 함은 정제, 산제, 좌제 등의 제형을 용매가 채워진 정해진 규격의 vessel 에 투입하여 녹아 나오는 정도를 측정하는 것으로, 이때 시간에 따라 녹아 나오는 정도에 대한 정보는 인체 내에서의 활성 물질의 반응과 제품의 제형에 대한 품질관리에 매우 중요한 자료가 된다.

품질관리 용출 되는 정도의 곡선이 주어진 기준 곡선과 부합하는가 ? 용출 되는 활성성분의 양이 주어진 각각의 시간에 따라 주어진 그래프와 일치 하는가 ? Example: Dissolved amount: After 5 min = 30 % OK/NOK? After 20 min = 80% OK/NOK? After 50 min = 85% OK/NOK?

연구 및 개발부 Pharmaceutical oral dosage form (tablet, etc.) In vivo Drug release Dissolution Characteristics (time, where is the dosage form dissolving, dissolution curve etc.) ?

약전에 의한 용출법 Apparatus 1 Apparatus 2 Apparatus 3 Apparatus 4 Used for Tablets, Capsules, especially when the media is changed during the test run Standard Apparatus, used for solid dosage forms BioDiss: Used when the medium and the pH is changed continuously Used for lipophilic solid dosage forms suppositories and soft capsules

Apparatus 5 Apparatus 6 Disks and Extraction cells are used to test transdermal patches. The Rotating cylinder is used to Test Transdermal patches. PTSWO: Special Tester for Suppositories, Soft Gels and similar products

탈기, 용매의 제조 “ The United States Pharmacopoeia (USP) ” recognises that dissolved gases in the Dissolution Media may affect Dissolution Test Results and recommends that gases should be removed before the test is performed ” (USP23/NF18) Prepared Medium to reproducible standards USP prescription of : Heating, Circulating and Vacuum The Temperature of the Media must be in the range of 37 +/- 0,5 °C

탈기의 중요성 Particle with associated air bubble. The dissolution process is highly influenced.
