3 major types of insulin?
how are they categorized? What rapid insulins are inhaled, and work faster than regular insulin? |
rapid acting, intermediate, long-acting
time of onset, duration of effect Lispro, Aspart, Glulisine |
|
Insulin secretagogues are useful for which DM type?
oldest/longest medication class: Insulin sensitizer, biquanide: Effective in which DM type? PPAR-G receptor activators: |
Type 2
oral sulfonylureas Metformin both T1, T2 rosi, pioglitazone (Gamma = glucose) |
|
Amylin analog:
incretin mimetic: DP-4 inhibitor: |
pramlintide
exenatide sitagliptin |
|
Explain physiology of insulin release:
Differentiating factors between DKA, NKDC: Electrolyte imbalance, causing arrhythmias, needing insulin: |
B-cells in pancreas detect increased BS --> block ATP-dependent K+ channel --> depolarization, Ca++ influx --> insulin release
DKA - lower BS, fruity breath, Kussmaul respirations, acidosis hyperkalemia |
|
onset/duration of rapid-acting insulins:
onset/duration of long-acting insulins: Which type do you give right before meals? Rapid-acting can mix with what other type of insulin? |
< 1hr, 4-8 h.
1-2 hrs, up to 24 h. rapid acting NPH - intermediate |
|
Which type of insulin cannot be mixed?
Which insulins are given SQ, not IV? Non-clear insulins should not be given by ____. How is Lispro structure different from human insulin? |
long-acting
glulisine, long-acting insulins IV Lys/Pro are switched in the chain |
|
How is Aspart different?
Glulisine differences? Why is Lispro quicker acting than regular insulin? Patient education with Lispro should include what? |
Aspartic acid for proline
Glutamic acid for proline structure allows it to escape the SQ tissue tell them to freakin' eat right after. |
|
Main difference between detemir and glargine?
When do you give rapid insulin? How often is intermediate/long acting administered? Monitoring levels for FPG, PPG, Hgb A1C, Urine glucose/ketones: |
detemir soluble at physiological pH - less variable absorption; glargine forms microprecipitates, soluble at acidic pH
immediately before meals intermediate - BID, QD long acting - usually QD FPG - 90-130, PPG - <180, Hgb <7%, negative glucose/ketones |
|
Which DM type still needs insulin w/ a missed meal?
Two classic medications that raise glucose: Dawn phenomenon, treatment: |
Type 1
glucocorticosteroids, BB's early am hyperglycemia due to loss of activity - give more insulin, change to longer-acting |
|
Insulin secretagogues are used in which type of DM?
2 classes? How often are OS and meglitinides given? Which generation of OS are usually given and why? |
Type 2
oral sulfonylureas (1st gen -amides, 2nd gen -ides), meglitinides (-linides) OS - QD (like long-acting insulins) meglitinides - 15-30 min before meal 2nd gen - less active metabolites, less SE's |
|
Indications for secretagogues:
What should you monitor in OS/meglitinides: chlorpropamide has what unique SE's? MOA/indications of Metformin: |
type 2 uncontrolled by diet/exercise alone
OS - SCr/BUN, meg's - LFT's disulfiram-like flushing, hyponatremia (SIADH) insulin sensitizer - doesn't increase secretion - uncontrolled T2DM |
|
SE's of Metformin:
Contraindications: A-glucosidase inhibitors, MOA, dosing, SE's: |
Metallic taste, GI, lactic acidosis, anemia
increased risk of lactic acidosis - COPD, liver disease Acarbose, Miglitol - bind membrane A-glucoside hydrolase, amylase; blocks absorption of carbs; give TID SE's - GI (farting, bloating, diarrhea); treat with DEXTROSE only |
|
PPAR-G activators:
MOA? Unique non-glucose effects: AE's: |
TZD's, glitazones - Rosi (Avandia), Pio (Actos)
bind PPAR-G receptor - regulate gene expression/proteins - better insulin sensitivity Rosi - increases TC, LDL, TG Pio - no effect on TC, LDL, decreased TG's liver, weight gain, anemia, MI |
|
Amylin analogs, MOA:
Indications, administration: AE's: |
Pramlintide - neuroendocrine peptide produced w/ insulin, slows GI emptying, suppresses glucagon, improves satiety
uncontrolled T1/T2 DM already on insulin; give SQ TID and reduce insulin by 1/2 N/V, rash, dizziness, HA |
|
Incretin mimetic, hormones it mimics, and effect on glucose/GI:
unique aspects of MOA: Dosing, SE's: |
exenatide - GIP, GLP-1 - increased insulin secretion, decreased glucagon, gluconeogenesis, slowed gastric emptying, satiety
only increases insulin in high BS; doesn't affect normal response given SQ BID, reduce dose of other drugs - SE's of N/V, GI, HA |
|
DPP-IV inhibitor, MOA:
Dosing, SE's: What is the ultimate goal of Hgb A1C levels in tx of DM? |
sitagliptin (Januvia) - blocks DPP-IV, inhibits metabolism of GLP, GIP
give PO QD - SE's - GI, no wt loss Hgb < 7 |
