the purpose of the present study was to explore the passive and electrically assisted transdermal transport of granisetron hydrochloride (gra) in solution and gel formulation through iontophoresis and also the feasibility of delivering therapeutic amounts of drug for the treatment of chemotherapy-induced nausea and vomiting. in this study, iontophoretic permeation of gra through guinea pig skin...

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...

Background: Due to its minimal systematic adverse effects, transdermal estrogen is widely used for the prevention of osteoporosis in postmenopausal women.The present meta-analysis aimed to clarify the effects of transdermal estrogen on bone mineral density (BMD) of postmenopausal women.Methods: Studies were identified by searching electronic databases including Cochrane Library, MEDLINE, Embase...

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 ...

Interest in bacteriophages as therapeutic agents has recently been reawakened. Parenteral delivery is the most routinely-employed method of administration. However, injection of phages has numerous disadvantages, such as the requirement of a health professional for administration and the possibility of cross-contamination. Transdermal delivery offers one potential means of overcoming many of th...

Nanoemulsions have been widely applied to dermal and transdermal drug delivery. However, whether and to what depth the integral nanoemulsions can permeate into the skin is not fully understood. In this study, an environment-responsive dye, P4, was loaded into nanoemulsions to track the transdermal translocation of the nanocarriers, while coumarin-6 was embedded to represent the cargoes. Particl...

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...

BACKGROUND AND THE PURPOSE OF THE STUDY Sertraline hydrochloride is a selective serotonin reuptake inhibitor principally used in the treatment of major depressive disorder. To maintain the therapeutic plasma drug concentration of the drug for prolonged period, the transdermal drug delivery has been chosen as an alternative route of drug delivery. The pharmacokinetic properties of sertraline hyd...
