But per what? This study reveals no further information about this. So maybe someone who is used in such matters can help me.

microM stands for microMolar (M = moles/litre), which is a concentration term. It's sort of like parts per million, but not really. Parts per million is on a mass basis, whereas microMolar is molecules in a given volume. One mole is 6.022 X 10^23, so one microM solution is 6.022 X 10^17 molecules per liter of solution.
Few drugs (none?)would reach microM concentrations under normal therapeutic use, as far as I know.
