UNLABELLED SUMMARY  AIM To evaluate the use of transdermal buprenorphine patches (Transtec®) in routine clinical practice. PATIENTS & METHODS A prospective, noninterventional, postmarketing study performed in the Czech Republic by 71 investigators in various clinical practice settings. Patients with chronic moderate-to-severe cancer pain, or chronic severe noncancer pain insufficiently cont...

Although sildenafil citrate (SC) is used extensively for erectile dysfunction, oral delivery of SC encounters many obstacles. Furthermore, the physicochemical characteristics of this amphoteric drug are challenging for delivery system formulation and transdermal permeation. This article concerns the assessment of the potential of nanomedicine for improving SC delivery and transdermal permeation...

BACKGROUND Psoriasis is an autoimmune disease that is caused by a shift in the Th1/Th2 balance toward Th1-dominant immunity. It has been established as an effective treatment to counteract psoriasis by subcutaneous injection of recombinant interleukin (IL)-4, and IL-4 gene therapy by topical transdermal penetration has shown its antipsoriatic effect in mice. Retinoic acid (RA) and dimethylsulfo...

Transdermal drug delivery is the application of drug on the skin surface so that it can permeate through the skin and reaches the systemic circulation at sufficient concentration to ensure therapeutic efficacy. Transdermal drug delivery system (TDDS) has several advantages over conventional system; TDDS offers sustained drug release, avoidance of first pass effect, patient compliance, ease of a...

Objective: The present study aimed to develop transdermal patches containing alkaloid fraction, flavonoid fraction and tannin fraction from Ficus racemosa bark and to assess its wound healing potency. Methods: In the present investigation, herbal transdermal patches were formulated using natural polymer Protanal LF10/60 by solvent evaporation technique. The physicochemical parameters like flexi...

BACKGROUND Postmenopausal estrogen replacement therapy (ERT) has an antioxidant effect that opposes the oxidation of LDL particles. Oral ERT-induced increases in plasma triglyceride, however, decrease LDL particle size, which may counteract this antioxidant effect. Because transdermal ERT decreases plasma triglyceride, it may not decrease LDL particle size and may preserve estrogen's antioxidan...

The purpose of this research was to develop a matrix-type transdermal therapeutic system containing drug Diclofenac acid, Pressure Sensitive Adhesive (PSA) like acrylic adhesive by the solvent evaporation technique. Different concentrations of Labrasol, oleic acid and triacetin were used to enhance the transdermal permeation of diclofenac acid. Polyethylene monolayer film as a backing membrane ...

OBJECTIVES To evaluate the effects of transdermal estrogen therapy on bone mineral density (BMD) in postmenopausal Korean women. METHODS A total of 149 healthy postmenopausal women were retrospectively evaluated: 100 were on hormone therapy (HT) and 49 were the control group. For the HT group, 54 applied estrogen transdermally using either a patch (n = 21) or gel (n = 33), and 46 took estroge...

BACKGROUND Lipid-based nanosystems have great potential for transdermal drug delivery. In this study, nanostructured lipid carriers (NLCs) for short-acting alkaloids lappacontine (LA) and ranaconitine (RAN) isolated from Aconitum sinomontanum (AAS) at 69.47 and 9.16% (w/w) yields, respectively, were prepared to enhance percutaneous permeation. Optimized NLC formulations were evaluated using uni...

OBJECTIVE Activated protein C (APC) resistance not related to the factor V Leiden mutation is a risk factor for venous thrombosis. Oral estrogen replacement therapy (ERT) has been reported to induce APC resistance. Little is known about the effect of transdermal estrogen. METHODS AND RESULTS We enrolled 196 postmenopausal women who were randomly allocated to receive either 1 mg 17beta-estradi...
