OBJECTIVES To evaluate the treatment of Peyronie's disease (PD) with verapamil and dexamethasone iontophoresis. METHODS Twenty nine patients with PD were treated by means of a Miniphysionize" dispositive 3 sessions a week during 4 consecutive weeks. 5mL of a combination of verapamil(10mg.) and dexamethasone (4mg.) were transdermally administered with a 2.5 mA current during 20 min. The aim ...

This study aims to develop an amperometric glucose biosensor, based on carbon nanotubes material for reverse iontophoresis, fabricated by immobilizing a mixture of glucose oxidase (GOD) and multiwalled carbon nanotubes (MWCNT) epoxy-composite, on a planar screen-printed carbon electrode. MWCNT was employed to ensure proper incorporation into the epoxy mixture and faster electron transfer betwee...

The aim of this study was to investigate the feasibility of using layer-by-layer polymer coated gold nanoparticles (AuNP) as a carrier for topical iontophoretic delivery of imatinib mesylate (IM). AuNP were prepared by the Turkevich method and were stabilized and functionalized using polyvinylpyrrolidone and polyethylene imine. The functionalized AuNP were then sequentially coated with anionic ...

celecoxib is used in the treatment of osteoarthritis, rheumatoid arthritis, acute pain, joint inflammation and sport injuries. long term administration of the drug results in such complications as gastrointestinaland renal disturbances and cardio-vascular complications. the main objective of the present study was to investigate the feasibility of delivering celecoxib incorporated in gel formula...

Cardiovascular disease is the leading cause of death in western societies, and endothelial dysfunction is one of the earliest signs seen in the development of such conditions. The development of prognostic tools to aid in the prediction of microand macrovascular disease, based on assessment of vascular reactivity, is therefore of paramount importance. Transdermal iontophoresis offers a quick, n...

Nicotine transdermal systems are being used as an aid to smoking cessation programs. As the kinetics of nicotine delivery is important in success of a smoking cessation program, rapid and high input of nicotine is required, which is not possible by passive methods and requires enhancement strategies such as iontophoresis. Iontophoretic permeation, of nicotine looks promising, based on published...

formulation by using chemical penetration enhancers and to study the effect of pulsed current on permeation through guinea pig, Wistar rat and human cadaver skin. Modified Franz diffusion cell was used to study the in vitro permeation across various types of skin by iontophoresis. The thermo-reversible gel was prepared and optimized by cold method using poloxamer 407 as a gelling agent. Thermo-...

Allograft bone is widely used in orthopaedic surgery, but peri-operative infection of the graft remains a common and disastrous complication. The efficacy of systemic prophylactic antibiotics is unproven, and since the graft is avascular it is likely that levels of antibiotic in the graft are low. Using an electrical potential to accelerate diffusion of antibiotics into allograft bone, high lev...

Vitamin B12 deficiency, which may result in anemia and nerve damage if left untreated, is currently treated by administration of cyanocobalamin via oral or intramuscular routes. However, these routes are associated with absorption and compliance issues which have prompted us to investigate skin as an alternative site of administration. Delivery through skin, however, is restricted to small and ...

Superoxide dismutase (SOD) is a potent antioxidant agent that protects against UV-induced skin damage. However, its high molecular weight is a significant obstacle for efficient delivery into the skin through the stratum corneum and development of antioxidant activity. Recently, we developed a non-invasive transfollicular delivery system for macromolecules using a combination of liposomes and i...
