Transbuccal Permeation of a Nucleoside Analog, Dideoxycytidine: Effects of Menthol as a Permeation Enhancer

International Journal of Pharmaceutics, 1999
The use of a safe and effective permeation enhancer is paramount to the success of a buccal drug delivery system intended for systemic drug absorption. The enhancing effects of menthol (dissolved in an aqueous buffer in the absence of co-enhancers) on buccal permeation of a model hydrophilic nucleoside analog, dideoxycytidine (ddC), were investigated ...

Effect of Permeation Enhancers and Organic Acids on the Skin Permeation of Indapamide

International Journal of Pharmaceutics, 2008
The aim of present study was to investigate the transdermal properties of indapamide and to explore the efficacy of various permeation enhancers and organic acids with regard to the percutaneous absorption of indapamide. Permeation experiments were performed in vitro, using rat abdominal skin as a barrier. In the permeation studies, 2-chamber diffusion

A Skin Pharmacokinetics Study of Permeation Enhancers: The Root Cause of Dynamic Enhancement Effect on in Vivo Drug Permeation

European Journal of Pharmaceutics and Biopharmaceutics, 2023
Skin pharmacokinetics (SPK) of permeation enhancers can answer the question of why enhancement effects different at the kinetic level. Herein, SPK of permeation enhancers were classified into two categories, namely, lateral elimination (elimination to surrounding stratum corneum (SC)) and longitudinal elimination (elimination to deep epidermal (EP ...

Effect of Iontophoresis and Permeation Enhancers on the Permeation of an Acyclovir Gel

Current Drug Delivery, 2010
The purpose of the present study was to explore the combined effect of chemical enhancers and iontophoresis on the in vitro permeation of acyclovir gel across porcine skin. Acyclovir gel was formulated using carbopol 940 and hydroxypropyl methylcellulose K4M (HPMC K4M). Effect of drug concentration on the delivery of acyclovir was examined.

Effects of Adhesives and Permeation Enhancers on the Skin Permeation of Captopril

Drug Development and Industrial Pharmacy, 2001
To formulate a transdermal drug delivery system of captopril, monolithic adhesive matrix type patches containing 20% captopril, different pressure-sensitive adhesives, and various permeation enhancers were prepared using a labcoater. The effects of the adhesives and permeation enhancers on skin permeation of captopril from the prepared patches were ...

Homoharringtonine is a transdermal granular permeation enhancer

Biochemical and Biophysical Research Communications, 2022
Although modulation of claudin-1-based tight junction (TJ) in stratum granulosum is an option for transdermal absorption of drugs, granular permeation enhancers have never been developed. We previously found that homoharringtonine (HHT), a natural alkanoid, weakened intestinal epithelial barrier with changing expression and cellular localization of TJ ...

Intestinal Permeation Enhancers

Journal of Pharmaceutical Sciences, 2000
This review addresses the field of improving oral bioavailability through the use of excipients that increase intestinal membrane permeability. The critical issues to consider in evaluating these approaches are 1) the extent of bioavailability enhancement achieved, 2) the influence of formulation and physiological variables, 3) toxicity associated with

Permeation Enhancers for Transdermal Drug Delivery

Drug Development and Industrial Pharmacy, 2000
The transdermal route has been recognized as one of the highly potential routes of systemic drug delivery and provides the advantage of avoidance of the first-pass effect, ease of use and withdrawal (in case of side effects), and better patient compliance.
