5 Sulfonylurea ( 혈당에무관하게 ) 췌장베타세포에서인슐린분비증가

6 Sulfonylurea 장점신속한효과, 뛰어난혈당강하능력, 가격저렴 단점저혈당발생체중증가고인슐린혈증이차성설폰요소제실패 ( 원인 : 체중증가, 운동부족, 점진적인인슐린저항성의증가, 인슐린분비의결핍 )

7 Meglitinides 장점 빠른효과 (10 분이내작용시작 ) 짧은작용지속시간적은저혈당빈도식후혈당조절용이식사직전에복용식사를거를때는약을복용안한다. 저혈당적음신기능이상시사용가능 단점 상대적으로약한혈당강하능력체중증가저혈당유발가능하루에여러번복용해야함

8 말초조직에서인슐린효과증진 비만환자에서처음사용약제 공복혈당감소에효과적 체중증가가없음 단독요법시저혈당발생하지않음 심혈관위험율을감소시킴 지방간개선효과 Metformin 장점

9 부작용 : 소화불량, 오심, 구토, 금속맛, 복부팽만감, 설사 소량부터서서히증량 약의대부분이신장으로배설, 신기능이상시에는사용못함 극히드물게치명적인유산혈증유발가능 CT 촬영시일시중단해야함 Metformin 단점 PET 촬영시정상, 악성감별힘들게함

10 말초조직에서인슐린효과증진 내장지방감소 Glitazone (Pioglitazone) 낮은저혈당빈도 단독요법시저혈당발생하지않음 동맥재협착억제 작용 고혈압및지질치개선효과

11 혈당강하효과를나타내기까지오래걸린다. (4 주이후에효과 ) Glitazone (Pioglitazone) 수분저류, 부종, 체중증가 심부전시사용금기 인슐린과같이사용시주의 간기능검사필요 (?) 단점 단독요법보다병합요법이효과적

15 Alpha Glucosidase Inhibitors 기전 : 소장에서포도당흡수억제, 지연사용방법 : 매식사직전복용 특징 : 식후급격한혈당상승억제효과, 식후고혈당에효과 장점 : 저혈당, 체중증가없음. 혈청지질농도에영향이없음단점 : 평균혈당강하능이낮음. 부작용 : 위장증상 ( 복부팽만, 방귀, 설사 ) 소화기계증상금기 : 염증성장질환, 신기능장애시금기
