Influence of iontophoresis on delivery of NSAID-loaded deformable liposomal dispersions: and evaluation.

Negatively charged deformable liposomes (DL) of ketoprofen were formulated to enhance transdermal delivery of ketoprofen (KP) under the influence of iontophoresis for intraarticular delivery. Conventional and deformable KP liposomes were prepared using thin film hydration, characterized and intraarticular delivery of KP was evaluated using Sprague-Dawley rats. Vesicles displayed entrapment efficiency (>71%); zeta potential <-25 mV; size between 152.

Convective Solvent Transport Pathways for Absorption of Drugs from Topical Formulation.

Physicochemical and formulation factors influencing penetration of drugs from topical products into the skin and mechanisms of drug permeation are well investigated and reported in the literature. However, mechanisms of drug absorption during short-term exposure have not been given sufficient importance. In this project, the extent of absorption of drug molecules into the skin from aqueous and ethanolic solutions following a 5-min application period was investigated.

Liposomes as Carriers for the Delivery of Efavirenz in Combination with Glutathione-An Approach to Combat Opportunistic Infections.

Human immunodeficiency virus (HIV)-infected individuals display an enhanced production of reactive oxygen species (ROS). This reduction of antioxidant capacity in host tissues has been related to the decrease in total levels of ROS scavengers such as glutathione (GSH). Prevention of opportunistic infections due to a weakened immune system is becoming a key strategy along with HIV elimination.

Evaluation of nanoparticle drug-delivery systems used in preclinical studies.

Multifunctional nanoparticles have been identified as a promising drug-delivery system for sustainable drug release. The structural and size tunability and disease-targeting ability of nanoparticles have made them more suitable for multiple drug loading and delivery, thereby enhancing therapeutic results through synergistic effects. Nanoparticulate carriers with specific features such as target specificity and stimuli-responsiveness enable selective drug delivery with lower potential side effects.

Iontophoretic Mediated Intraarticular Delivery of Deformable Liposomes of Diclofenac Sodium.

Background And Objective: Topical therapy is ineffective in the case of Musculoskeletal Disorders (MSD) as it is not able to maintain therapeutic levels of the drug in the affected joint due to its inability to surpass the dermal circulation and penetrate into deeper tissues. One of the approaches to enhance deep tissue penetration of drugs is to increase drug delivery much above the dermal clearance. The objective of the present work was to formulate negatively charged Deformable Liposomes (DL) of Diclofenac Sodium (DS) using biosurfactants and target the same to the synovial fluid by application of iontophoresis.

Liposomes as carriers of resveratrol and vitamin E: Evaluating ameliorative antioxidant effect using chemical and cellular test systems.

Resveratrol (RES) in combination with antioxidant vitamins is reported to be more effective in protecting the cells from oxidative stress rather than any of these antioxidants alone. In continuation to our previous work using resveratrol and vitamin C, our main aim was to evaluate the antioxidant restorative effect using chemical and cellular test systems on resveratrol co-encapsulated vitamin E (VE) within liposomes. Z-average size was less than 135 nm, polydispersity index < 0.

Thermosensitive liposomal gels loaded with antimicrobial agent for oral care in critically ill patients.

A novel thermosensitive gel loaded with meropenem (MP) liposomes was designed to improve retention in the oral cavity as a prophylactic measure to prevent ventilator-acquired pneumonia in critically ill patients. Meropenem liposomes were incorporated into poloxamer 407 gels and gamma irradiated. Mean size of liposome was 247 nm, polydispersity index < 0.
