Methimazole
anti-osteoporotic drug with adverse effect of osteonecrosis of jaw and subtrochanteric fracture
denosumab and bisphosphonates
why should denosumab not be used together with bisphosphonates
both can cause osteonecrosis of jaw and subtrochanteric fracture as adverse effects
DOC for osteoporosis in general
bisphosphonates
DOC for severe hypocalcemic tetany
calcium gluconate IV
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.

bisphosphonates
example of selective estrogen receptor modulator (SERM)
raloxifene
only IV form of bisphosphonate
zolendronic acid or zolendronate
MOA of this anti-osteoporotic drug is preventing RANKL to bind to RaNKL receptor leading to osteoclast inhibition . This drug is also a human monoclonal antibody
Denosumab
This hormone found in pancreatic islets of langerhan modulate appetite and regulate gastric emptying

glucagon is an inhibitor of insulin secretion. true or false
False. Glucagon STIMULATES insulin secretion. on the other hand, insulin INHIBITS glucagon. Ang selfish ng insulin noh
