19
Q

What are SGLT2 inhibitors associated with?

A

increased UTIs

20
Q

What could SGLT2 inhibitors lead to?

21
Q

ketoacidosis

A

metabolic state with high concentrations of ketone bodies

22
Q

structural modification of phlorizin has lead to a number of SGLT2 selective inhibitors by _____

A

lead optimization

23
Q

(SAR) OH group on B ring of SGLT2 inhibitors

A

not essential for inhibition

**responsible for toxicity

24
Q

What can dual therapy help with?

A

reduce blood glucose quicker and remain there longer

25
complications of DM
neuropathy nephropathy microangiopathy macroangiopathy
26
T/f all diabetics will develop the late complications associated with the disease
true
27
DCCT study
T1D * **keep BG levels under tight control - slows progression of damage
28
UKPDS study
T2D * **keep BG levels under tight control - decreased complications
29
People newly diagnosed with T2D but otherwise good health, ADA suggests aiming for _____
tight control (normal) + lifestyle changes
30
Ideal HbA1C under tight control
6-6.5%
31
People who have had diabetes for awhile, HbA1C goal is
slightly higher 7.5-8%
32
Why would people who already have diabetes have looser blood sugar control?
- older age - frequent bouts of hypoglycemia - presence of other medical conditions requiring multiple meds and needing more than 2 drugs to lower BG - limited finances
33
Who is tight control most worthwhile for?
healthy people who can live at least 10 more years
34
Who is not recommended to go on tight control?
- children **need glucose for brain development | - elderly
35
Ways to measure hyperglycemia
- glucose levels - Frductosamine - glycated hemoglobin (HbA1C - 1,5-AG
36
How do you measure fructosamine?
colorimetric procedure
37
How do you measure HgA1C?
affinity chromatography
38
How do you measure glucose levels?
blood | urine
39
1,5-AG
naturally occurring monosaccharide | 100% non metabolized
40
1,5 AG during hyperglycemia
decrease
41
1,5 AG post hyperglycemia
return to normal
