Q

Mechanism of action: Glucose

A

Enters Beta cell via GLUT2–> glycolysis produces ATP–> ATP closes K channels–> cell depolarizes–> Ca channels open–> insulin release

Q

Mechanism of action: Metformin

A

bypasses insulin receptor–> directly into cell–> stim PPAR and inhibits mitochondrial glycerophosphate dehydrogenase–> ↑ tissue sensitivity to insulin and ↓ liver gluconeogensis

19
Q

SE’s of Metformin

A

possible lactic acidosis, GI distress; CI in CHF. NO weight or hypoglycemia

20
Q

Mechanism of action: Acarbose & Miglitol

A

inhibits a-glucosidase in SI–>↓ breakdown of glucose to absorbable carb–>↓ postprandial glucose–> ↓insulin demand. NO HYPOGLYCEMIA

21
Q

SE’s of Acarbose & Miglitol

A

GI discomfort, flatulence, diarrhea, hepatotoxicity

22
Q

Thiazolidinediones

A

Pioglitazone and Rosiglitazone

23
Q

Mechanism of action: Thiazolidinediones

A

bind to nuclear PPARy–> transcription of insulin-responsive genes–> sensitization of tissues to insulin, ↓hepatic gluconeogenesis and TGs, and ↑insulin receptor numbers

24
Q

SE’s of Thiazolidinediones

A

GOOD: less hypoglycemia than sulfonylureas, ↓TG ↑HDL

BAD: weight gain, bone fractures, increased bladder cancer and edema; CI in CHF; Rosiglitazone ↑ LDL

25
Q

Mechanism of action: Exenatide

A

GLP-1 receptor agonist; GLP-1 ↑glucose-dependent insulin secretion, ↓glucagon secretion, slows gastric emptying, ↑satiety; used in type 2 diabetes in combo w/other

26
Q

SE’s of Exenatide

A

nausea, hypoglycemia w/sulfonylureas, acute pancreatitis, caution w/renal insufficiency

27
Q

Mechanism of action: Sitagliptin

A

inhibits DPP-4 (which normally inactivates GLP-1)

28
Q

Mechanism of action: Repaglinide and Nateglinide

A

Closes K channels–>stimulates insulin release; T2DM

29
Q

Mechanism of action: Pramlintide

A

slows rate of food absorption–> ↓glucose production and ↓appetite; T1DM and T2DM

30
Q

Meglitinides: Drug types and SE’s

A

Repaglinide and Nateglinide; weight gain, hypoglycemia, very short acting

31
Q
