bisphosphonates
27
anti-osteoporotic drug associated with risk of infection

teriparatide
30
anti-thyroid drug that can cause cutis aplasia (congenital malformation)
Methimazole
31
anti-osteoporotic drug with adverse effect of osteonecrosis of jaw and subtrochanteric fracture
denosumab and bisphosphonates
32
why should denosumab not be used together with bisphosphonates
both can cause osteonecrosis of jaw and subtrochanteric fracture as adverse effects
33
DOC for osteoporosis in general
bisphosphonates
34
DOC for severe hypocalcemic tetany
calcium gluconate IV
35
net effect of PTH vs Vitamin D vs Calcitonin on calcium and phosphate level
PTH increases calcium and decreases phosphate. VITAMIN D increases both. CALCITONIN decreases both.
36
alendronate, ibandronate, zolendronic acid are examples of
bisphosphonates
37
example of selective estrogen receptor modulator (SERM)
raloxifene
38

44
this sulfonylurea has no active metabolite drug being excreted thru the kidneys
glipizide
45
thiazolidinediones have this pancreatic sparing effect and will decrease insulin requirement due to this action
improve GLUT 4 expression in muscle and adipose
46
main mechanism for the glucose lowering effect of metformin
decrease hepatic glucose output
47
examples of rapid acting insulin
lispro, aspart, glulisine (walang LAG kasi rapid)
48
examples of long acting insulin
detemir, degludec, glargine (think of glalalalaalalaglargine. matagal mag gargle ganun. to differentiate it from glulisine)
49
rapid acting insulin appearance in solution
clear
50
this specific insulin is in an acidic solution that when injected subcutaneously will form stable aggregates...
glargine. kaya siya long acting
51
true or false. insulin is used for emergency treatment of hypokalemia.
false. for hyPERkalemia dapat
52
insulin is composed of what 2 polypeptides
A chain (21AA) and B chain (30AA)
53
this glucose transporter is insulin mediated and facilitates glucose uptake from muscles and adipose tissue

54
what is the only type of insulin that can be given intravenously
short acting insulin (regular insulin)
55
due to its acidic pH, this long acting insulin should not be mixed with short acting or rapid acting insulin

67
exenatide and liraglutide are examples of
GLP1 receptor agonist
68
pramlintide is an example of
amylin mimetic
69
anti diabetic drug class that decrease hepatic glucose output

72
anti diabetic drug class that are PPAR gamma agonist, increases number of GLUT 4 transporters in muscle and adipose tissue
thiazolidinediones (-glitazone)
73
anti diabetic drug class that binds bile acid in intestinal tract
bile acid sequestrant (colesevelam)
74
