In the present study, is to development of Azelnidipine (AZP) transdermal patches and to study the effect of Dimethyl sulfoxide (DMSO) on drug permeation through across the rat abdominal skin. The transdermal patches were prepared by solvent casting method using different amounts and combination of hydroxyl propyl methyl cellulose (HPMC E15), Ethyl cellulose (EC) and Eudragit RS100 (ERS). The d...

Skin permeability and local blood perfusion are important factors for transdermal drug delivery. Application of heat is expected to enhance microcirculation and local perfusion and/or blood vessel permeability, thus facilitating drug transfer to the systemic circulation. In addition, heating prior to or during topical application of a drug may facilitate skin penetration, increase kinetic energ...

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...

objective (s): transdermal preparations for testosterone are becoming popular because of their unique advantages such as avoidance of first-pass effect, convenience, improved bioavailability, and reduction of systemic side effects. a novel testosterone transdermal delivery system (tdds) was developed using a palm oil base called hamintm (a commercial product) and tested using in vitro and in vi...

The use of Acetyl Salicylic Acid (ASA) in the secondary prevention of cardio vascular diseases is well known. Orally administered ASA is rapidly metabolized to its principal metabolite Salicylic Acid (SA) in the gastrointestinal fluids, during absorption in the intestine and liver. ASA, and not its hydrolysis product SA, which exhibits antithrombotic activity. Transdermal delivery of acetylsali...

Flurbiprofen, a potent nonsteroidal anti-inflammatory drug, is widely used for relief of pain in patients suffering from rheumatic diseases, migraine, sore throat and primary dysmenorrheal. However, this drug has many gastrointestinal side effects produced by its oral administration, such as gastric bleeding and peptic ulcer. These effects were responsible for non-compliance among patients, whi...

Article history: Received on: 15/12/2012 Revised on: 24/02/2013 Accepted on: 11/03/2013 Available online: 30/03/2013 Verapamil Hydrochloride is a calcium channel blocking anti-anginal agent. Extensive first pass metabolism, low bioavailability (~20%) and short biological half life (4.8 hrs) altogether makes it an ideal candidate for transdermal drug delivery. The objectives of this study were t...

The present work comprises the formulation and evaluation delivery system of transdermal drug with a view of developing and preparing a losartan potassium releasing system utilizing natural oils as permeation enhancers for transdermal applications. Matrix systems were prepared by using polyvinyl pyrrolidine and ethyl cellulose (EC) polymers by incorporating dibutyl phthalate as plasticizer and ...

Rivastigmine, an anti-Alzheimer’s drug, is effective in the treatment of mild to moderate dementia. Oral immediate release (IR) formulation suffers from limitation like severe GI adverse effects which may even result in treatment interruption, like vomiting, diarrhea and anorexia resulting in wide fluctuations in drug plasma levels and calling for altered frequency of dosing. Even the Novel Dru...
