How to memorize those equations? every time I see them and have an example, I can carry it out easily. However, when I just move to questions at the end of the chapter, I can not remember anything!!

Simple: repetition.

stuff that you're weak on, especially equations - which imo, are easy points on the exam; with an exception to some of the biostats question, should be all easy points.

write them out every morning right before you start studying. yeah, there's a lot, but when you get that x > 260, you really won't care. also, try to understand what you're solving for, that'll make the ease of getting absorbed into your mammillary bodies easier. :naughty:
 
I suggest doing practice questions from outside of Uworld, if you have exhausted Uworld: The Katzung and Lange Pharm book is good. The Guyton physio review book is good.

Here's all the Pharm equations I needed for my class's PK test (note that I also go to lecture, so this is a summary of learning, not the process of learning):


t1/2 = .7 x Vd / CL
C_ss = Infusion rate / CL
Infusion rate_ss = Rate of elim_ss = CL x TC / F
CL = dose / AUC = Rate of elim / C = Vmax / (Km + C)
Rate of elim = CL x C = Vmax x C / (Km + C)
Loading dose = Vd x Css / F = Maint dose x F
Maint dose = Dosing rate x Intv
AF = 1 / %(LOST in 1 Intv)
PeakCss = PeakC1 x AF
pH - pK = log [deprot] / [prot] ; A- / AH ; B / BH+
pH > pK ---> DEPROTONATE (ionize weak acids in base, ionize weak bases in acid)

I have not run into a UWorld question that didn't use an equation in the back of FA (or one you could derive very easily). Just write those out a bunch and you should be set.
