metformin
not sulfonurea( they increase insulin release from pancreas thereby driving the glucose and lead to obesity |
|
how metformin work
|
block gluconeogenesis and increased tissue sensitivity to insulin
reduce intestinal glucose ansorbtion # 1 choice for obese patients be aware of lactic acidosis |
|
when metform is contrind
|
in P with renal disfunction because it can accumulate and cause metabolic acidosis and in elderly
COPD CHF alcohol abuse hepatic disease be aware of lactic acidosis especially if serum Cr .1.4 in fem and >1.5 in male |
|
sulfonylureas
|
tolbutamide
chlorpropamide glyburide glipizide glimepiride stimulate insuline secretionfrom beta cells in pacreas, expect drop of HgA1C on 2 % #1 choice for BMI <30 asymp or mild DM without pregancy ( contrindicated) if Hb A1C>7-- add acarbose orthiasalidine ( increase Gi abcrobt of glucose) or insuline insulin is need when hyperglycemia is out if control even in insulin resistance most offet ass with hypo glycemia |
|
thiasolinidiones
|
improve the insulin resistance and pancreatic beta cells function
m |
|
thiasolinidiones what may precipitate
|
acute CHF exacerbation especially in those with underlying CHF and bone loss
|
|
rapid acting secretagogues--
|
nateglydine
repaglydine very short life can cause immediate release of insulin they do not add any therap effect to sulfonurea |
|
increatins
|
exenatide- synthetic analog exendine 4? polypeptide that mimics incretin and promote insulin secretion ....
they are part of mechanism when oral glucose normally produce a rise in insulin adn decrease glucagon level GLP1- SQ administration BID reduces gastric emptying, causing early satiety and help in weight loss stimulate insuline secretion inhibit glucagon secretion they decrease DM type 2 |
|
increatins adv effe
|
nausea in 30 %
may cause pancreatitis |
|
dipeptydil peptidase 4 ingibitors
|
sitagliptin inhibit the enzyme dipeptudile peptidas 4.. который ингибирует increatin
increatin>>>incres insulin release and reduc gluycagon secretion |
|
alfa glucosidase inhibitors
|
acarbose , miglitol (-) enzyme that digest complex carbohydrates
block glucose absorb in the bowek they add a 50 % of decrease in Hb A1C they cause flatus diarrea abd pain |
|
pramlintide
|
synthetic analog of the polypeptide pancreatic hormone amylin with slows gastric emptying, suppress glucagon and regulate appetite
