The present study was undertaken to develop a suitable transdermal matrix patch of Metoprolol tartrate with different proportions of polyvinyl pyrrolidone (PVP) and chitosan crosslinked with glutaraldehyde (GA). The prepared transdermal patches were subjected to different physicochemical evaluations such as thickness, tensile strength, folding endurance, drug content, swellability, surface pH, ...

The present study was undertaken to develop a suitable transdermal matrix patch of ketorolac tromethamine with different proportions of polyvinyl pyrrolidone (PVP) and ethyl cellulose (EC) using a D-optimal mixture design. The prepared transdermal patches were subjected to different physicochemical evaluation. The surfacet opography of the patches was examined by scanning electron microscopy (S...

The availability of nicotine-replacement therapies is very low in India, as there are only a few importers. Currently, negligible forms of transdermal patches are available, they are expensive, and not easily accessible to the common man. In this study, an attempt was made to develop transdermal patches of nicotine, which are cost effective and conducive to the Indian market. Two types of patch...

We reported that nicotine applied via a transdermal patch (21 mg/day) induced viral reactivation and ocular shedding in herpes simplex virus type 1 (HSV-1) latent rabbits. One possible mechanism of action involves the release of catecholamines and other similar agents, triggering HSV reactivation. Bupropion (Zyban, Wellbutrin), a non-nicotine aid to smoking cessation, inhibits neuronal uptake o...

Transdermal systems are attractive methods of drug administration specifically when treating patients for drug addiction. Current systems however are deficient in therapies that allow variable flux values of drug, such as nicotine for smoking cessation or complex dosing regimens using clonidine when treating opioid withdrawal symptoms. Through the use of functionalized carbon nanotube (CNT) mem...

Controlled-release delivery of 6-beta-naltrexol (NTXOL), the major active metabolite of naltrexone, via a transdermal patch is desirable for treatment of alcoholism. Unfortunately, NTXOL does not diffuse across skin at a therapeutic rate. Therefore, the focus of this study was to evaluate microneedle (MN) skin permeation enhancement of NTXOL's hydrochloride salt in hairless guinea pigs. Specifi...

The efficacy of oral aspirin treatment in the secondary prevention of cardio and cerebro vascular disease is well known. However oral administration is often associated with abdominal discomfort. The feasibility of delivering aspirin transdermally from eudragit and polyvinyl acetate (PVA) matrix-type patches to enhance its antithrombotic efficiency of aspirin was investigated. Transdermal films...

Background: Duloxetine hydrochloride is an antidepressant drug also approved for diabetic neuropathy, anxiety disorders, and fibromyalgia requiring repeated administration on chronic basis. The objective of this study was to develop a transdermal drug delivery system for duloxetine hydrochloride as a once daily dosage form. Methods: Transdermal patches were prepared by solvent evaporation metho...

Transdermal patches are now widely used as cosmetic, topical and transdermal delivery systems. These patches represent a key outcome from the growth in skin science, technology and expertise developed through trial and error, clinical observation and evidence-based studies that date back to the first existing human records. This review begins with the earliest topical therapies and traces topic...

Purpose: To to develop and evaluate matrix-type ondansetron hydrochloride (OS) transdermal patch for the treatment of chemotherapy-induced nausea and vomiting. Methods: Transdermal patches were prepared by solvent casting method using ethyl cellulose and polyvinyl pyrrolidone as matrix materials, and dibutyl phthalate and dibutyl sebacate as plasticizers. The formulations were evaluated for pat...
