Polyethylene glycols (PEGs) 600,1000, and 2000 were used to study the molecular weight
permeability dependence in the rat nasal and gastrointestinal mucosa. Absorption of the …

The permeation of fentanyl and sufentanil through cadaver skin membranes was investigated
using in vitro diffusion cell techniques. Neither drug influenced the permeation of the other …

The 3-day AAPS/FDA Workshop on ‘Bioequivalence of Topical Dermatological Dosage
Forms–Methods of Evaluating Bioequivalence’, held on September 4–6, 1996 in Bethesda, Md., …

The hair follicle, hair shaft, and sebaceous gland collectively form what is recognized as the
pilosebaceous unit. This complex, three-dimensional structure within the skin possesses a …

Results of permeation experiments involving finite dose diffusion cells with hairless mouse
skin as the membrane indicate that neither intact liposomes nor the phospholipid of which …

The physicochemical properties of select opioid and anilinopiperidine narcotic analgesics
were investigated. The solubilities of the narcotics in hexane and water and, for morphine, in …

Transdermal delivery of fentanyl from various adhesive matrix formulations to achieve a
steady‐state skin flux was investigated. For this purpose, various pressure‐sensitive adhesives …

A method to study the influence of hydration on skin permeability where the skin is immersed
in saline for up to 30 hr and under circumstances where a steady state rate of permeation …

In order to develop a basic concept of the permeability of the human nail plate and thus create
a better understanding of the toxic potentials and therapeutic possibilities of substances …

The permeation of intact hairless mouse skin by alkanols was studied. The method is described,
and data for the quasi-steady-state and nonstationary-state aspects of mass transfer are …
