According to TMF, we should not use buffered Cetomacrogolcreme for erythromycin but buffered for cortisone preparations. What now with next preparation? Betamethasone Dipropionate

I must begin by saying that the doctor should be informed that in this creme composition The two drugs are incompatible. These two medicines should be prescribed separately for the reason, which you tighten yourself. I would take buffered cream and thus give priority to the Cortico. But due to the large amount of erythromycin, the pH will move up to a value between 5.6 and 8.

Fair: a NOT recommendable combination! Miracles are not possible, not in the Galenic pharmacy!
