true
Difference between myfortic and cellcept
myfortic is enteric coated to decrease diarrhea
Cellcept IV is stable in ____ only
D5W
mycophenolate drug interactions considerations
reduce efficacy of oral contraception
Mycophenolate works by
inhibiting T- and B-lymphocyte proliferation by altering purine nucleotide synthesis

A patient tells you they are deficient in TMPT. They may need a decreased dose of:
azathioprine

increased susceptibility to infection
side effects of prograf
(tacrolimus)
increased BP
nephrotoxicity
increased BG
neurotoxicity

trough level goal
(electrolytes are monitored as well as renal fxn, LFTs, BG, BP, lipids)
T/F: Tacrolium XL and IR are not interchangeable
true
Tacrolimus is a CYP_____ ____
CYP450 3A4 and P-gp substrate
Tacroliumus IV considerations
must use a non-PVC bag
Cyclosporine brand names include:
gengraf, neoral, sandimmune, restasis (eye drops)
Gengraf boxed warning
nephrotoxicity, increased risk of lymphoma and other malignancies, skin cancer, increased risk of infection, increased BP
Difference between Gengraf/Neoral and Sandimmune
Gengraf/Neoral are modified formulations of cyclosporine with greater bioavailability compared to non-modified Sandimmune
do not interchange them
Monitor cyclosporine with
trough levels, eletrolytes, renal function, BP, BG, lipids
Cyclosporine is a CYP_____
Cyp3A4 inhibitor, CYP3A4 and P-gp substrate
Considerations with oral liquid cyclosporine
do not administer from a plastic or styrofoam cup
mTOR kinase inhibitors include
everolimus and sirolimus
mTOR kinase inhibitors work by
inhibiting T-lymphocyte activation/proliferation; synergistic w/ CNIs
Zortress warnings
(everolimus)
hyperlipidemia, impaired wound healing
side effects of everolimus
peripheral edema, thrombosis
