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...

      Topical and transdermal drug delivery systems are noninvasive and can be self-administered with the minimization of side-effects, have received increased attention during the past few years. Nanoemulsions, emulsions sized between 20-200 nm with narrow distributions, offer several advantages for topical and transdermal delivery of pharmaceutical agents including controlled droplet size, th...

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 ...

Nowadays about 74% of drugs are taken orally and found not to be as effective required. To improve such characters transdermal drug delivery system was emerged. Drug through the skin attain a systemic effect is commonly known differs from traditional topical delivery. Transdermal systems (TDDS) dosage forms involves transport viable epidermal or dermal tissues for local therapeutic while very m...

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...

   Repeated oral administration of mexazolam, an anti-anxiety agent, may cause adverse effects such as gastric disturbance, drowsiness, and ataxia due to transiently high blood levels. Transdermal administration would avoid the systemic side effects and gastric disorders after oral administration. We have developed a matrix using ethylene-vinyl acetate (EVA), a heat-processible and flexible mat...

Background and aim: Eczema is a common inflammatory skin disease. Although history and physical examination are important in diagnosis of allergen, because of extent of environmental allergens, those are not simply recognized. The objective of this study was to determine allergens in patients with contact or atopic dermatitis referred to Razi hospital.Materials and Meth...

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 Drug Delivery System (TDDS) is one of the systems lying under the category of controlled drug delivery, in which the aim is to deliver the drug through skin in a predetermined and controlled rate. Hypertension is one of the common disorder for the mankind. It is not a disease in itself, but is an important risk factor for cardiovascular mortality and morbidity. The present article d...
