In A classic nasal ointment, ephedrine base occurs. May these be replaced by ephedrine HCl, given the base can no longer be purchased in Belgium? Menthol 200mg Eucalyptol

You obviously have little choice. The use of ephedrine HCl does cause a few modifications, given its solubility in water (in the 5dr Adrenaline solution). When using ephedrine base, we may assume that this product will also be curable with eucalyptol and menthol. This mixture is then immediately soluble in the oils present. Whether this will be the case with the hydrochloride I don't know. Is to try out. Ephedrinehcl can partially dissolve in the adrenaline solution. A drama This is not there the prevailing pH will be still sour. This cannot be said for Borax. Borax will trigger a shift from an acidic pH to an alkaline. Therefore, in the past, solved questions (including question about a nasal ointment with fluimicil) are recommended not to use the solution but of a fixed dilution of adrenalin bitartrate. However, I have noticed that small packs of this product are not available. So that the use of the ampoules imposes itself to reduce the costs. I cannot find any justification for the presence of borax in the composition. Given the problems, which this product entails, I would definitely delete it in the presence of adrenalin in dissolved form.
