the application of low-frequency ultrasound for transdermal delivery of insulin is of particular public interest due to the increasing problem of diabetes. the purpose of this research was to develop an air ultrasonic ceramic transducer for transdermal insulin delivery and evaluate the possibility of applying a new portable and low-cost device for transdermal insulin delivery. twenty-four rats ...

Aim: The objective of the present research work was to formulate and compare two different kinds of penetration enhancer in transdermal patch with placebo patch using a drug (Salbutamol sulphate) and compare for in vitro drug release. Study Design: The transdermal patches of Salbutamol sulphate were prepared by solvent evaporation technique using different ratios of Hydroxy propyl methylcellulo...

lisinopril dihydrate (angiotensin converting enzyme inhibitor) is a lysine derivative of enalaprilat and does not require hydrolysis to exert pharmacological activity. it has an extensive hepatic first pass metabolism resulting in a bioavailabil-ity of 6-60%. to overcome the poor bioavailability of the drug, transdermal patches have been prepared. the present study also aims at optimization of ...

Article history: Received on: 07/11/2013 Revised on: 21/12/2013 Accepted on: 16/01/2014 Available online: 27/02/2014 Nisoldipine is used for treatment of hypertension and angina pectoris. However, it suffers from very low bioavailability due to its extensive pre-systemic metabolism. This together with its low dose made it excellent candidate for transdermal delivery. Accordingly, the aim of thi...

AIM To uptake and release hydrophilic model drugs and insulin in a novel conductive polymer (CP) nanotube transdermal patch. MATERIALS & METHODS The externally controlled transdermal delivery of model drugs and insulin were tested ex vivo and results were compared with CP films. The unique intrinsic properties of CPs provide electrostatic interaction between the model drugs and polymer backbo...

A new frontier in the administration of therapeutic drugs to veterinary species is transdermal drug delivery. The primary challenge in developing these systems is rooted in the wide differences in skin structure and function seen in species ranging from cats to cows. The efficacy of a transdermal system is primarily dependent upon the barrier properties of the targeted species skin, as well as ...

Transdermal delivery that avoids the presystemic disposition can provide an alternative to oral administration of tadalafil. Accordingly, the aim of this study was to select the best vehicle as the first step in optimization of tadalafil transdermal delivery. The vehicles were used neat or in selected binary combinations and were evaluated for drug solubilization and transdermal delivery. The d...

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...

PURPOSE The main objective of the investigation was to develop a transdermal therapeutic system for alfuzosin hydrochloride and to study the effects of polymeric system and loading dose on the in vitro skin permeation pattern. MATERIALS AND METHODS Principles of experimental design have been exploited to develop the dosage form. Ratio of ethyl cellulose (EC) and polyvinyl pyrrolidone (PVP) an...
