Hi All,

» What‽ If you would succeed in demonstrating BE of C_max you would have proven that your product is not an ER. Bizarre idea.

Hmmm
the only option I see is something like this

t <- c(seq(0,24,0.1))

ka <- .5

ke <- 0.1

D = 100

V = 2

C <- D/V*(ka/(ka-ke))*(exp(-ke*t) - exp(-ka*t))

C[50] <- C[50]*10

ggplot2::qplot(t,C, geom = "line")

Could it be Mexico's reviewers ER vision?
