insulin glargine

Pronunciation

/ˈɪnsəlɪn ˈɡlɑːrdʒiːn/ Mechanism of action Recombinant human insulin analog modified (asparagine → glycine at A21; two arginines added at B30) so it is soluble at acidic pH (pH 4 in vial) but precipitates at the neutral pH of subcutaneous tissue. The microprecipitate slowly dissolves, releasing insulin into circulation over \\~24 hours with a relatively flat (\\"peakless\\") profile. Binds insulin receptors, promoting glucose uptake into muscle and adipose tissue and suppressing hepatic gluconeogenesis. Provides basal insulin coverage \\[1\\]. Standard dosing -/
