Transdermal delivery holds a promising carrier in the transport of drugs to get direct access across the skin deep into the systemic circulation.. It has attracted many researchers due to various biomedical advantages. The barrier nature of stratum corneum poses a threat to the drug delivery. However, various attempts have been made to modify this property of the skin and thus, to improve the t...

the aim of the present study was to investigate the influence and the mechanisms of cineoleand terpineol on the in-vitro transdermal delivery of huperzine a from microemulsions, andtheir potential synergistic effect on the permeation enhancement. the transdermal deliveryof huperzine a from microemulsions with different concentrations of cineole and terpineolthrough the rat abdominal skin was de...

In past few decades, scientists have made tremendous advancement in the field of drug delivery systems (DDS), through transdermal pathway, as the skin represents a ready and large surface area for delivering drugs. Efforts are in progress to design efficient transdermal DDS that support sustained drug release at the targeted area for longer duration in the recommended therapeutic window without...

Transdermal administration of drugs is generally limited by the barrier function of the skin. Colloidal systems are one of the most contentious methods for transdermal delivery of active substances across the skin. The colloidal systems helps in overcoming the shortcomings associated with transdermal drug delivery systems and provide sustained and controlled release of drugs. This review presen...

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...

Microemulsions have received great attention for applications in transdermal drug delivery. The use of curcumin for treating various skin diseases like scleroderma, psoriasis, and skin cancer was extensively reported. The solubility of curcumin in various oils, surfactants, and cosurfactants was studied herein in order to find the optimal components for a transdermal delivery vehicle. Microemul...

We recently reported that electret, which was prepared by a corona charging system with polypropylene film, could enhance the transdermal delivery of several drugs of low molecular weight. The aim of this study was to investigate whether electret could enhance the transdermal delivery of protein drugs by N-trimethyl chitosan nanoparticles (TMC NPs) prepared by an ionic gelation method. A series...

one of the most significant issues in pharmaceutical industries, prior to commercializationof a pharmaceutical preparation is the “preformulation” stage. however, far too attention hasbeen paid to verification of the software assisted statistical designs in preformulation studies.the main aim of this study was to report a step by step preformulation approach for a semisolidpreparation based on ...

Transdermal delivery that avoids the presystemic disposition can provide an alternative to oral administration of tadalafil. Accordingly, the aim of this study was to select the best vehicle as the first step in optimization of tadalafil transdermal delivery. The vehicles were used neat or in selected binary combinations and were evaluated for drug solubilization and transdermal delivery. The d...

Transdermal medication delivery systems provide systemic therapy by passive diffusion through the skin. They offer an alternative route of medication administration and may be well suited for patients who are unable to take or retain oral medications. Granisetron transdermal system (Sancuso(R), ProStrakan, Inc.) is the first transdermal medication patch indicated for the prevention of nausea an...
