Itraconazole in treatment for Yeast{malassezia]

I am a vet in Hong Kong and our practice has been using Itraconazole for treatment of Malassezia with limited success. I have read that it is universally accepted that itraconazole is not effective against yeast....is that true and is the mode of action in yeast different to fungi. Also some practitioners are using pulse therapy for the yeast....is this feasible given that the yeast live on the skin and not in the hair shaft as does the fungus.

i look forward to your reply

Thank you...Dr gavin hay
