Alpha cells in the pancreas
|
produce glucagon
|
|
Beta cells in the pancreas
|
produce insulin
|
|
Beta cells are found
|
Islets of Langerhans
|
|
Delta cells in the pancreas
|
produce somatostatin
|
|
product of proinsulin cleavage used to assess insulin abuse
|
C-peptide
|
|
Exogenous insulin
|
Little C-peptide
|
|
Endogenous insulin
|
Normal C-peptide
|
|
very rapid acting insulin, having fastest onset and shortest duration of action
|
Lispro (humalog)
|
|
rapid acting, crystalline zinc insulin used to reverse hyperglycemia
|
Regular (Humulin R)
|
|
Long acting insulin
|
Ultralente (humulin U)
|
|
Ultra long acting insulin, has over a day duration of action
|
glargine (Lantus)
|
|
Major SE of insulin
|
hypoglycemia
|
|
Important in synthesis of glucose to glycogen in the liver
|
GLUT 2
|
|
Important in muscle and adipose tissue for glucose transport across muscles and TG storage by lipoprotein lipase activation
|
GLUT 4
|
|
Examples of alpha-glucosidase inhibitors (AGI)
|
Acarbose, miglitol
|
|
MOA of AGIs
|
Act on intestine, delay absorption of glucose
|
|
SE of AGIs
|
flatulence, diarrhea, abdominal cramps (do not use beano to tx)
|
|
Alpha-glucosidase inhibitor associated with elevation of LFTs
|
Acarbose
|
|
Amino acid derivative
|
nateglinide (D-phenylalanine)
|
|
MOA of nateglinide
|
insulin secreatagogue
|
|
Biguanide
|
Metformin
|
|
Drugs available in combination with metformin
|
Glyburide, glipizide, and rosiglitazone
|
|
MOA of metformin
|
decreases hepatic glucose production and intestinal glucose absorption; increase insulin sensitivity
|
|
Most important potential SE for metformin
|
lactic acidosis
|
|
Meglitinide
|
repaglinide
|
|
MOA of repaglinide
|
insulin release from pancrease; faster and shorter acting that sulfonylurea
|
|
First generation sulfonylurea
|
Chlorpropamide, tolbutamide, tolazamide
|
|
Second generation sulfonylurea
|
glyburide, glipizide, glimepiride, etc
|
|
MOA of both generations
|
insulin release from pancreas by modifying (closing) K channels
|
|
Common SE of sulfonylureas, repaglinide, and nateglinide
|
hypoglycemia
|
|
Sulfonylurea NOT recommended for elderly because very long half life
|
Chlorpropamide
|
|
Thiazolidinediones
|
Pioglitazone, Rosiglitazone, Troglitazone(withdrawn from market)
|
|
Reason troglitazone was withdrawn from market
|
hepatic toxicity
|
|
MOA of thiazolindinediones
|
stimulate PPAR-gamma receptor to regulate CHO and lipid metabolism
|
|
SE of thiazolindinediones
|
Edema, mild anemia; interaction with drugs that undergo CYP4503A4 metabolism
|
|
Hyperglycemic agent that increases cAMP and results in glycogenolysis, gluconeogenesis, reverses hypoglycemia, also used to reverse severe beta-blocker OD and smooth muscle relaxation
|
Glucagon
|
|
Pramlintine
|
Type 1 and 2- analog of amylin activates amylin receptors- RANK- suppresses glucagon release, slows gastric emptying, works in CNS to reduce appetite
|
|
Exenatide
|
long-acting injectable peptide analog of GLP-1; used in combo with metformin or sulfonylurea for Type 2
|
