L36 Antidiabetic drugs Flashcards
A1C test
Insensitive to recent meals
Measures glycation of hemoglobin
Standard of Care for treating diabetes
Sulfonylureas
Regulation of Insulin release
ATP/ADP low (fasting), K channel open, cell hyperpolarized, L-type Ca closed, insulin not secreted
ATP/ADP high, K channel open, cell depolarized, Ltype Ca open, insulin secreted
Sulfonylurea mechanism
Bind to subunit of Beta cell ATP K channel
Standard of Care
Meglitinide use
Used before meals, short duration
Stops K channel
Secretagogues
Sulfonylurea
Meglitinide
Incretins (work on GLP1 receptor)
Incretins
Glucagon like peptide 1 acts on GLP 1 receptor to stimulate insulin release
Metformin mechanism
Opposes glucagon
Inhibits respiratory chain complex I
Thiazolidinediones mechanism
Effects on PPAR-gamma decrease insulin resistance
Alpha-glucosidase inhibitors mechanism
inhibit digestion of glucose
