Topical Nano and Microemulsions for Skin Delivery
Nanosystems such as microemulsions (ME) and nanoemulsions (NE) offer considerable opportunities for targeted drug delivery to and via the skin. ME and NE are stable colloidal systems composed of oil and water, stabilised by a mixture of surfactants and cosurfactants, that have received particular interest as topical skin delivery systems. There is considerable scope to manipulate the formulatio...
متن کاملMicroemulsions- Potential Carrier for Improved Drug Delivery
The novel carriers have been exploited through almost all the routes of administration. Association of drugs with carriers is normally noncovalent, based on collective strength of weak binding forces. Many newer carriers are evolving with the advent of technology and the demand of targeted delivery like microemulsions. Microemulsions are clear, stable, isotropic mixtures of oil, water and surfa...
متن کاملImplantable Devices for Sustained, Intravesical Drug Delivery
In clinical settings, intravesical instillation of a drug bolus is often performed for the treatment of bladder diseases. However, it requires repeated instillations to extend drug efficacy, which may result in poor patient compliance. To alleviate this challenge, implantable devices have been developed for the purpose of sustained, intravesical drug delivery. In this review, we briefly summari...
متن کاملDevelopment and Evaluation of Microemulsions for Transdermal Delivery of Insulin
Insulin-loaded microemulsions for transdermal delivery were developed using isopropyl myristate or oleic acid as the oil phase, Tween 80 as the surfactant, and isopropyl alcohol as the cosurfactant. The pseudoternary phase diagrams were constructed to determine the composition of microemulsions. The insulin permeation flux of microemulsions containing oleic acid as oil phase through excised mou...
متن کاملWater-in-oil microemulsions for effective transdermal delivery of proteins.
INTRODUCTION A water-in-oil microemulsion is a thermodynamically stable emulsion that has the capacity to 'hide' water-soluble molecules within a continuous oil phase. The very small size of the water droplets within the microemulsion means that these types of formulation can be applied topically to the skin, with the result that peptides and proteins can be delivered effectively into the derma...
