Insulin half life and metab
3-5 minutes
Insulases in liver (50%), kidney, placenta
C-peptide half life and metab
3-4x insulin
Degraded by kidney
Benefit of short insulin half life
permits rapid changes in circulating levels
Benefit of long C-peptide half life
ideal marker of endogenous insulin produx and secretion
Basal insulin purpose
COntrol plasma glucose during fasting/between meals to prevent liver from making too much glucose
prevent ketosis
T1DM insulin dosing
Basal 24hrs + rapid w meals
T2DM insulin dosing
start basal and progress to meals if needed
NPH dosing
Humulin-N
Novolin-N
QHS or BID
DOA 12-16 hrs
