I am preparing microemulsion of Lornoxicam, which is soluble in 7.4 pH buffer and 0.1 N NaOH, but in the screening of various oils, I have to dilute the saturated solution of drug in oil. However, when in dilute with 7.4 pH buffer and 0.1 N NaOH, which is immissible with oils, what do I have to do to dilute the saturated oils solutions?
