drug names 
MOA 
SE 
Indications 
contras
A

-liflozin
Canagliflozin, Dapagliflozin, Ertugliflozin, Empaglifozin

MOA: increases urinary glucose excretion by lowering renal glucose threshold—–reabsorbtion of filtered glucose in the tubular lumen of kidney

SE:

  • decrease the sodium reasborption causing—OSMOTIC DIURESIS—– causing HYPOTENSION
  • genitourinary infections-frequent UTIs and yeast infections
  • transient n/v

Indications:
-can be given with metformin

contra:
- renal impairment

102
Q

which drug is approved to reduce cardiovascular events in PTS with DM 2

A

Empagliflozin—– NA-glucose cotransporter 2 inhibitor

103
Q

whats the advantage to first line PO agents?

A

better overall HgA1C reduction over time

104
Q

List the SQ injectables for DM 2
what is their drug class
MOA
general BBW for all

A

-tide
GLP-1 rec agonists

Dulaglutide (truicity)
Liraglutide
Semaglutide
Exenatide

MOA: long acting GLP-1 receptor agonists–they increase glucose dependent insulin release, decreases secretion of glucagon, slows gastric empty and increases satiety

BBW: can cause medulary thyroid CA
CONTRA IN MEN 2 PT

109
Q

Other non-hyperglycemic agents to give
Indications?
MOA

A

Bromocriptine–dopamine agonist

Colvestram–bile sequestrant

  • not really used due to high SE profile
  • would be given to pre-DM

MOA: somehow lowr HbA1C
