It was aimed to develop the matrix type polysaccharide-based transdermal films of nifedipine (NFD) to provide its long term plasma concentration. The mechanical tests were carried out on gel formulations which were utilised in the fabrication of transdermal films to determine the type of polymer (pectin, sodium alginate) and plasticizer (propylene glycol, glycerine) as well as their concentrati...

Iron deficiency anemia is one of the major nutritional deficiency disorders. Iron deficiency anemia occurs due to decreased absorption of iron from diet, chronic blood loss and other associated diseases. The importance of iron and deleterious effects of iron deficiency anemia are discussed briefly in this review followed by the transdermal approaches to deliver iron. Transdermal delivery of iro...

Transdermal drug delivery (TDD) is a non-invasive route of drug administration, although its applications are limited by low skin permeability. It is an attractive alternative technique over the conventional techniques for administration of systemic approaches. For both local and systemic effects skin is the major site of application. However, to penetrate the drug through skin, stratum corneum...

Sinomenine is extracted from Sinomenii caulis (a traditional Chinese medicine), and it is used as the active ingredient in rheumatic arthritis treatments. It has been used in clinical applications for decades. However, there are some disadvantages, including low activity in transdermal permeation and a high dosage being clinically required. To overcome these defects, sinomenine was used as a pr...

Transdermal delivery is preferable for some drugs to oral administration or intravenous injection. Macromolecules such as peptide drugs, however, little penetrate through the skin. Iontophoresis is an effective transdermal method for macromolecules. In this study the effect of duration of applying electric field and degree of current density has been investigated under in vitro conditions. The ...

Transdermal transport is now becoming one of the most convenient and safe pathways for drug delivery. In some cases it is necessary to use skin penetration enhancers in order to allow for the transdermal transport of drugs that are otherwise insufficiently skin-permeable. A series of oleanolic acid amides as potential transdermal penetration enhancers was formed by multistep synthesis and the s...

Oxybutynin is an efficacious treatment for overactive bladder, but its clinical utility is hampered by relative intolerability due to its side effect profile. Over the last few years, various attempts to enhance the tolerability of oxybutynin by varying the drug delivery mechanism have been introduced and have included extended release, rectal suppository, transdermal patch, and gel formulation...
