Pancreatic hormones and anti diabetic drugs Flashcards
insulin dependent DM
Type 1
4 categories if Diabetes Mellitus
Type1 insulin dependent
Type 2 non insulin dependent
Type 3 juvenile
Type 4 Gestational DM
non insulin dependent DM
Type 2
juvenile DM
Type 3
Gestational DM
Type 4
4 main cell types in pancreas
glucagon
insulin
somatostatin
pancreatic polypeptide
alpha pancreatic cells secrete
glucagon
beta pancreatic cells secrete
insulin
gamma pancreatic cells secrete
somatostatin
effects of insulin on liver
inhibit glycogenolysis
inhibit conversion of AA and FA to keto acids
inhibit AA to glucose
anabolic action
effects of insulin on muscle
increase CHON. synthesis, AA transport, ribosomal synthesis
increase glycogen synthesis, glucose trasport
inhibits phosphorylase
effects of insulin on adipose tissue
increase triglyceride stores
lipoprotein lipase induced
glucose transport into cells
inhibits intracellular lipase
rapidly acting insulin
Lispro
Aspart
Glulisine
rapidly acting insulin (1) onset of action and (2) peak
ONSET: 15 minutes
PEAK: 30-90minutes
taken before meals
duration of action is 3-5 hours
rapidly acting insulin
crystalline zinc insulin that is now made by recombinant DNA techniques
short acting insulin
short acting insulin onset of action
within 30 min
peak of short acting insulin
2-4 hours after SQ
short acting insulin duration of action
5-8 hours
regular insulin / short acting insulins
Novolin
Humulin
regular insulin should be administered within
30-45 mins
intermediate acting insulin which combines insulin and protamine
Neutral Protamine Hagedorn or isophane insulin
intermediate acting insulin onset of action
1-2 hours
intermediate acting insulin peak
8 hours
duraton of action is 12-16 hours
intermediate acting insulin
usually mixed with regular, lispro, aspart, or glulisine insulin
NPH or isophane intermediate acting insulin
duration of action >24 hours
onset of actin 1-2 hrs
DETEMIR long acting insulin
soluble “peakless” insulin given once daily
GLARGINE Long acting insulin
insulin glargine onset of action
slow onset of action 1-1.5 hrs
insulin lispro, aspart, glusine acutely mixed with NPH
Pre-mixed insulin (doesnt affect rapid absorption)
available concentration of insulin
100 U/ml
external open loop pump for insulin delivery
Continuous SQ insulin infusion device (abdomen, flank, thighs)
most recently developed long scting insulin
DOSE dependent
DETEMIR insulin
insulin therapy formula
(wt in lbs) / (4) or
0.55) x (wt in kg
conventional insulin therapy
for DM type 2
fixed dose of intermediate or long acting
vary dos of short or rapidly acting
condition caused by inadequate or absent insulin replacement
Diabetic Ketoacidosis (DKA)
Tx for DKA
regular insulin IV 0.1IU/kg/h + IV hydration
DM type 2 characterized by HYPERGLYCEMIA and DEHYDRATION
Hyperosmolar Hyperglycemic Syndrome (HHS)
Tx for Hyperosmolar Hyperglycemic Syndrome (HHS)
aggressive rehydration and restoration of glucose
LOW DOSE Insulin therapy
most common complication of insulin therapy
HYPOGLYCEMIA
2 major disorders of insulin therapy
insulin allergy
immune insulin resistance
immediate type hypersensitivity, rare condition
insulin allergy
disorder where low titer IgG anti insulin antibodies neutralize the action of insulin
immune insulin resistance
abnormal or degenerative conditionof the body’s adipose tissue
Lipodystrophy
oral anti diabetic agents
Secretagogues BIGuanides Thiazolidinediones Alpha-glucosidase inhibitors Incretin based therapies Amylin analogs
insulin secretagogues
Sulfonylureas
