The solubilisation of griseofulvin in 1 wt% aqueous micellar solutions of Pluronic F127 at 37 degrees C has been modified by adding polyethylene glycol PEG 35000 or poly(vinylpyrrolidone) PVP K30. The solubilisation capacity expressed in terms of unit weight of F127 is increased by the addition of 0.5 wt% PEG 35000 to a value approaching double that of a 2.5 wt% solution of F127 alone, but there is no advantage in adding 0.5 wt% PVP K30.
