Treatment of diabetes COPY Flashcards
albiglutide
incretin - GLP-1 analogues
- Secretion
- Etneroendocrine cells (L cells) in ileum encoded by proglucagone gene and derived from natrual proglucagon protein
- GLP1 release stimulated by nutrient entering the gut
- Physiological effects
- Pancreas: increases insulin secretion but decreases glucagon secretion
- Stomach: delays gastric emptying
- Hypothalamus: decrease appetite
- Analog
- Exenatide, liraglutide, albiglutide, duraglutide
- AE
- Nausea, vomiting and diarrhea

- Reduces postprandial glucose peak
- Competitive and reversible inhibitors of pancreatic a-amylase and intestinal a-glucosidase enzymes
- Acarbose and miglitol
- Often used in combination with other hypoglycemic agents
- No risk for hypoglycemia (you just arent absorbing as much)

more rapid onset of action
- MOA
- Similar to sulfonylureas by binding to SUR1 but at a different site to activation the K channel
