March 12 Exam - set 1 Flashcards
Raloxifene (type)
SERM
Calcitonin analogs (MOA)
decreased osteoclast activity;
blocks renal reabsorption of PO4 and Ca2+
Cinacalet
Calcium receptor potentiator
Binds to Ca-sensing region of CaR to inhibit PTH release
–allosteric modulator .. in presence of Ca2+, it makes it more effective at stimulating receptor
Vitamin D MOA
inc Ca2+ and PO4 abs from gut and reads from renal tubules
Bisphosponates MOA
inhibit bone reabsorption
- reduce formation and dissolution of hydroxyapatite crystals
- inhibit farnesyl-PP synthesis of osteoclasts
Suffix of bisphosphonates
-dronate
Teriparatide
PTH analog (aa 1-34)
Prolia (Denosumab)
Humanized monoclonal AB against RANKL .. binds RANKL to prevent activation of RANK and therefore prevent differentiation of osteoclasts
What is difference about atypical vs typical antipsychotics?
- Better affinity at D2 receptors
- Addition of activity at 5HT2A and others
- Better control over negative and cognitive sx (positive already controlled by typicals)
- Fewer EPS
Key feature of antipsychotics
block of D2 receptors
Dopamine pathways
Mesocortical/mesolimbic
-therapeutic and cognitive activities of D2 antagonists
Nigrostriatal (basal ganglia)
- motor control
- EPS sx arise here
First gen antipsychotics
Penothizaines
Haloperidol
2nd gen antipsychotic
–whats diff about it?
Clozapine
–acquisition of 5HT2A pharmacology
Aripirazole
D2 partial agonist
Classic early and atypical antipsychotics
Chlorpromazine
Haloperidol
Thioridazine
Sulpiride
