A solution with fluconazole in DMSO.

Given that fluconazole is not available as pure raw material, you will have to grind Diflucan and the obtained powder sieves. Then rub it off with DMSO. I suspect that Fluconazole will fix it in DMSO. But given that we do not have the certainty, we check the sedimentation of the powder suspended in DMSO. Should the suspended powder settle too quickly then I suspect the suspension can be stabilized with 0.25 à 0.5% Carbopol.
