T2DM Drugs Flashcards
Pharmacology
Name the 4 actions of T2DM drugs.
- increase insulin secretion
- decrease insulin resistance and reduce hepatic glucose output
- slow glucose absorption in GI tract
- enhance glucose excretion by kidney
name the 4 classes of drug that increase insulin secretion.
sulfonylureas
glinides (meglitinides)
incretic analogues
DPP-4 inhibitors
name the 2 classes of drug that decrease insulin resistance and hepatic glucose output
biguanides and thiazolidinediones (glitazones)
name the class of drug that slows glucose absorption from the GI tract
alpha-glucosidase inhibitor
name the class of drug that enhances glucose excretion by the kidney
sodium glucose type-2 (SGLT2) inhibitors
are alpha-glucosidase inhibitors and sodium glucose type-2 (SGLT2) inhibitors insulin dependent?
no
SUR1 subunits regulate __________ channel activity
SUR1 subunits regulate POTASSIUM channel activity
___ binding to each of the Kir6.2 subunits closes the channel causing ______________ of the ____ cell and _______ release
ATP binding to each of the Kir6.2 subunits closes the channel causing DEPOLARIZATION of the BETA cell and INSULIN release
ADP-Mg2+ binding to the SUR1 subunits ______ the channel maintaining the resting potential of the ____ cell and _________ insulin secretion
ADP-Mg2+ binding to the SUR1 subunits OPENS the channel maintaining the resting potential of the BETA cell and INHIBITS insulin secretion
sulfonylureas used in T2DM bind to SUR1 and _____ the channel causing _____________ and insulin release independent of plasma ________ concentration
sulfonylureas used in T2DM bind to SUR1 and CLOSE the channel causing DEPOLARIZATION and insulin release independent of plasma GLUCOSE concentration
