Journal ArticleDOI
The effects of ethanol on the transport of lipophilic and polar permeants across hairless mouse skin: Methods/validation of a novel approach
TL;DR: It is suggested that ethanol (< 50%) may work as an effective ‘fluidizing’ agent at some locus in the stratum corneum lipid bilayer at or near the polar head plane, but not in the bilayer hydrocarbon interiors.
Journal ArticleDOI
Cotransport of estradiol and ethanol through human skin in vitro: understanding the permeant/enhancer flux relationship.
TL;DR: The model demonstrates that ethanol enhances the stratum corneum transport of estradiol and of itself by increasing the respective diffusion coefficients at lower concentrations (<50%) and by both increasing the diffusion coefficients and decreasing the membrane activity coefficients at moderate concentrations (50 to 75%).
Journal ArticleDOI
Enhanced transdermal delivery of estradiol in vitro using binary vehicles of isopropyl myristate and short-chain alkanols
Melinda Goldberg-Cettina,Puchun Liu,James Alan Schriver Nightingale,Tamie Kurihara-Bergstrom +3 more
TL;DR: In this paper, the effect of binary vehicles of isopropyl myristate (IPM) and short-chain alkanols on the enhancement of skin permeation of estradiol (E 2 ) was studied in vitro using human epidermal membrane.

Andrea Leone-Bay,Kelly Kraft,Destardi Moye-Sherman,David Gschneidner,Maria A. P. Boyd,Puchun Liu,Pingwah Tang,Jun Liao,John E Smart,John J. Freeman +9 more
TL;DR: Phenoxy carboxylic acid compounds and compositions for the delivery of active agents are provided in this paper, with methods of administration and preparation as well as methods of preparation and administration.
Journal ArticleDOI
Pharmacokinetic and local tissue disposition of [14C]sodium diclofenac following iontophoresis and systemic administration in rabbits
Xiaoying Hui,Angela Anigbogu,Parminder Singh,Glen L. Xiong,Nicholas Poblete,Puchun Liu,Howard I. Maibach +6 more
TL;DR: The results suggest that the cutaneous microvasculature is not always a perfect "sink" and that transdermal iontophoresis facilitated the direct penetration of diclofenac sodium to deeper tissues.
