Abstract
Transdermal delivery of drugs through the skin to the systemic circulation provides a convenient route of administration for a variety of clinical indications. For transdermal delivery of drugs, stratum corneum is the main barrier layer for permeation of drug. So to circumvent the stratum corneum and to increase the flux through skin membrane, different approaches of penetration enhancement are used. Many reviews had described regarding iontophoresis, electroporation, sonophoresis, phonophoresis but other physical method of penetration enhancement like magnetophoresis, laser radiation and photomechanical waves, radio frequency, thermophoresis, microneedle based devices, skin puncture and perforation, needleless injection, suction ablation, application of pressure, skin stretching, skin abration are not exploited for reviews. These physical methods are used extensively to enhance permeation of drugs through skin. The review presents mainly the routes of penetration through skin and the physical approach of penetration enhancement to optimise the transdermal delivery system. Keywords: Transdermal; Penetration enhancement; Physical method; Skin.

Progress in recent years in the field of stimuli-responsive polymers, whose properties change depending on the intensity of a signal, permitted an increase in smart drug delivery systems (SDDS). SDDS have attracted the attention of the scientific community because they can help meet two current challenges of the pharmaceutical industry: targeted drug delivery and personalized medicine. Controlled release of the active ingredient can be achieved through various stimuli, among which are temperatur...

Abstract Nanosized materials have favorable applications in nanomedicine including photothermal therapy (PTT) and sonodynamic therapy (SDT) of most malignancies. Since conventional methods of cancer treatment encounter some limitations to this serious disorder, development of efficient routes is quite necessary. In this study, a gold/manganese dioxide nanocomposite (Au/MnO2 NC) was synthesized as a novel photo- and sono- responsive nanomaterial that was activated upon laser light of 808-nm wavel...

Pay-load deliveries across the skin barrier to the systemic circulation have been one of the most challenging delivery options. Necessitated requirements of the skin and facilitated skin layer cross-over delivery attempts have resulted in development of different non-invasive, non-oral methods, devices and systems which have been standardized, concurrently used and are in continuous upgrade and improvements. Iontophoresis, electroporation, sonophoresis, magnetophoresis, dermal patches, nanocarri...

This review demonstrates the progress, current status and problems of photodynamic therapy and laser photothermolysis for various skin diseases and rejuvenation. These new minimally invasive technologies are detailed from the points of view of their advantages and disadvantages. Particular attention is paid to complications, associated with prolonged dermal phototoxicity after intravenous photosensibilisation and insufficient intradermal penetration of photosensibilisers after local application ...

Transdermal drug therapy has made a breakthrough over the past few years amid emerging technologies and strategies for repositioning of drugs to deliver through the skin: a strong barrier. In spite of various benefits of transdermal routes of drug delivery such as avoidance of first-pass metabolism, easy mode of application, high patient compliance, and controlled release of medication, researchers today are facing numerous challenges in order for patients and clinicians to embrace transdermal d...

AbstractIn recent years, there has been a surge in the research and development of microneedles (MNs), a transdermal delivery system that combines the technology of transdermal patches and hypodermic needles. The needles are in the hundreds of micron length range and therefore allow relatively little or no pain. For example, biodegradable MNs have been researched in the literature and have several advantages compared with solid or hollow MNs, as they produce non-sharp waste and can be designed t...

The goal of delivery system is to get optimal therapeutic management. But, it still remains a challenge in the field of pharmaceuticals for delivery of ionic species and some non ionic. Several transdermal approaches have been used and recently the Iontophoretic technique has been widely used. This technique of facilitated movement of ion across a membrane under the influence of an externally applied potential difference is one of the most promising physical penetrations enhancing method. The ra...

Introduction: The success of drug delivery through the mucosal tissue of the oral cavity represents a current challenge as well as a great future perspective. The need for more rapid onset of action and improved absorption of medications has resulted in great development of drug delivery technologies that use physical methods to overcome the barrier properties of oral mucosae. Areas covered: This review discusses the various physical techniques which have been, and are being, explored to sustain...
