My doctor prescription me a medication and said I must drink 2L of water each day to make sure the medication will have maximum strength. Why does me peeing all day make the medication work better?

As others have said, ask your doctor.
But to add another potential reason, some medications have dehydration as a side effect (maybe it messes with thirst cues, increases urination frequency, increases sweating, etc).
