In Japan, transdermal fentanyl (Durotep Patch) was launched in March 2002, and it was regarded as making opioid rotation possible. When changing from morphine to transdermal fentanyl, the efficacy ratio of 1:150 is used in Japan as well as in many other countries. However, the ratio of 1:100 is used in Germany. As a result, a dose increase in transdermal fentanyl is often required to control pa...

Abstract Background Transdermal delivery of drugs is a quite challenging task for pharmaceutical scientists. The transdermal route preferred over the oral due to various advantages like avoidance first-pass effect, non-invasiveness, and high patient compliance. Therefore, it necessary develop an effective carrier system that enables passage drug through dermal barrier. Main body abstract Variou...

materials and methods liposomes were prepared by thin film method using soya lecithin and cholesterol. physicochemical characteristics of the liposomes such as, particle size, drug encapsulation efficiency were determined. also, drug release and in vitro skin permeability through rat skin were evaluated using franz diffusion cells. results the results showed that the maximum drug encapsulation ...

OBJECTIVES The importance of adolescent engagement in health decisions and public health programs such as immunisation is becoming increasingly recognised. Understanding adolescent preferences and further identifying barriers and facilitators for immunisation acceptance is critical to the success of adolescent immunisation programs. This study applied a discrete choice experiment (DCE) to asses...

PURPOSE The purpose of the present work was to assess iontophoretic permeation of Lisinopril at different current densities and concentrations for development of patient-controlled active transdermal system. METHODS In vitro iontophoretic transdermal delivery of Lisinopril across the pigskin was investigated at three different drug concentrations and three different current densities (0.25- 0...

Objective (s): Transdermal preparations for testosterone are becoming popular because of their unique advantages such as avoidance of first-pass effect, convenience, improved bioavailability, and reduction of systemic side effects. A novel testosterone transdermal delivery system (TDDS) was developed using a palm oil base called HAMINTM (a commercial product) and tested using in vitro and in vi...

Fentanyl citrate is a potent opioid that can be delivered by the transdermal route in cats and dogs. Publications regarding transdermal fentanyl patches were obtained and systematically reviewed. Seven studies in cats and seven studies in dogs met the criteria for inclusion in this review. Dogs achieved effective plasma concentrations approximately 24 hours after patch application. Cats achieve...

A dminMed is developing an innovative line of novel microneedle-based transdermal drug delivery devices. The current pipeline comprises an advanced microneedle arraybased pen-injector device (the AdminPen) that painlessly and conveniently injects therapeutic levels of standard liquid pharmaceutical drugs or cosmetic actives through the skin. This breakthrough technology revolutionizes the way i...

Background: Due to its minimal systematic adverse effects, transdermal estrogen is widely used for the prevention of osteoporosis in postmenopausal women.The present meta-analysis aimed to clarify the effects of transdermal estrogen on bone mineral density (BMD) of postmenopausal women.Methods: Studies were identified by searching electronic databases including Cochrane Library, MEDLINE, Embase...
