Article history: Received on: 07/11/2013 Revised on: 21/12/2013 Accepted on: 16/01/2014 Available online: 27/02/2014 Nisoldipine is used for treatment of hypertension and angina pectoris. However, it suffers from very low bioavailability due to its extensive pre-systemic metabolism. This together with its low dose made it excellent candidate for transdermal delivery. Accordingly, the aim of thi...

Coming Soon 10:15 Networking Coffee Break Critical Issues—The Pharmacokinetics of Transdermal Delivery 10:40 Minimization of CYP2D6 Polymorphic Differences and Improved Bioavailability via Transdermal Administration Thean Yeoh, Ph.D., Associate Research Fellow, Pfizer Transdermal delivery has the potential to offer improved bioavailability by circumventing first-pass gut and hepatic metabolism....

   Repeated oral administration of mexazolam, an anti-anxiety agent, may cause adverse effects such as gastric disturbance, drowsiness, and ataxia due to transiently high blood levels. Transdermal administration would avoid the systemic side effects and gastric disorders after oral administration. We have developed a matrix using ethylene-vinyl acetate (EVA), a heat-processible and flexible mat...

AIM To uptake and release hydrophilic model drugs and insulin in a novel conductive polymer (CP) nanotube transdermal patch. MATERIALS & METHODS The externally controlled transdermal delivery of model drugs and insulin were tested ex vivo and results were compared with CP films. The unique intrinsic properties of CPs provide electrostatic interaction between the model drugs and polymer backbo...

Transdermal administration of analgesic medications offers several benefits over alternative routes of administration, including a decreased systemic drug load with fewer side effects, and avoidance of drug degradation by the gastrointestinal tract. Transdermal administration also offers a convenient mode of drug administration over an extended period of time, particularly desirable in pain med...

OBJECTIVE To deliver 2,3,5,6-tetramethylpyrazine (TMP) in a relatively large dose through a transdermal route and facilitate the practical application of microemulison in transdermal drug delivery. METHODS The pseudo-ternary phase diagram for microemulsion regions was constructed using isopropyl myristate as oil phase, Labrasol(®) as surfactant, and Plurol(®) Oleique CC 497 as cosurfactant. A...

Advances in materials science and bionanotechnology have allowed the refinements of current drug delivery systems, expected to facilitate the development of personalized medicine. While dermatological topical pharmaceutical formulations such as foams, creams, lotions, gels, etc., have been proposed for decades, these systems target mainly skin-based diseases. To treat systemic medical condition...

Nowadays about 74% of drugs are taken orally and found not to be as effective required. To improve such characters transdermal drug delivery system was emerged. Drug through the skin attain a systemic effect is commonly known differs from traditional topical delivery. Transdermal systems (TDDS) dosage forms involves transport viable epidermal or dermal tissues for local therapeutic while very m...
