Controlled release of hydrocortisone acetate from dermal bases.


The effect of the complexation with beta-cyclodextrin, hydroxypropyl beta-cyclodextrin and polyvinylpyrrolidone on the diffusion kinetics of hydrocortisone acetate through a non porous lipidic membrane was analyzed starting from different dermal bases: a Carbopol gel and lanovaseline. A constant diffusive gradient was achieved; this suggests that the… (More)
