methotrexate MOA
blocks DHF reductase and conversion of DHF to THF
34
glucuronyl transferase in liver does what?
renders compounds water soluble
35
cyclooxygenase is acted on by what drug?
Aspirin - COX inhibited. Irreversible | NSAIDS - reversible
36
Thromboxane A2. Where is it synthesized and does it vasoconstrict or vasodilate?
synth in platelet | vasoconstricts and increases platelet aggregation
37
1. effect of proton blockers? 2. H2 blockers? 3. Ach? 4. Misoprostol?
1. blocks H+-K+ ATPase proton pump in parietla cell. not a receptor mediated event 2. blocsk H2 receptor which normally activate adenylate cyclase --> cAMP --> protein kinase 3. activates cholinergic receptor --> ca release --> protein kinase 4. blocks prostaglandin receptor whcih normally inhibits adenylate cyclase and cAMP production
38
7-fold membrane spanning protein drug?
propanolol a beta blocker
39
phase 3 clinical trials are?
double blind
40

MOA of finasteride
blocks 5-alpha reductase -- .testosterone to dihydrotest --> inc testosterone proximal to block --> dihyrotestosterone dec
44
MOA of flutamide, cyproterone, spironolactine
block androgen receptor --> testosterone/dihydrotestosterone inc but no physiologic effect
45
MOA of ketoconazole
inhib testosterone synth (supp adrenal steroid synth)
46
leuprolide MOA
GnRH analogue, which when given in sustined fashion inhibits FSHa dn LH --> lower testosterone and estrogen
