A new delivery system of clobetasol-17-propionate (lipid-loaded microspheres 0.025%) compared with a conventional formulation (lipophilic ointment in…
2004
Summary Background Topical application of clobetasol-17-propionate has been diffusely reported as an efficacious therapy in atrophic/erosive oral lichen planus (OLP), without exposing the patient to systemic side-effects. However, prolonged contact and respective topical effects on the oral mucosa should be avoided. Objectives The aim of the present study was to evaluate efficacy and compliance of new lipid microspheres loaded with 0·025% of clobetasol propionate (formulation A) compared with a commonly used formulation (a sort of dispersion of a lipophilic ointment in a hydrophilic phase) with the same amount of drug (formulation B) in the topical treatment of OLP. Patients and methods …
Antibacterial PEGylated Solid Lipid Microparticles for Cosmeceutical Purpose: Formulation, Characterization, and Efficacy Evaluation
2020
The development of efficacious means of delivering antioxidant polyphenols from natural sources for the treatment of skin diseases is of great interest for many cosmetic and pharmaceutical companies. Resveratrol (RSV) and Limonene (LIM) have been shown to possess good anti-inflammatory and antibacterial properties against Staphylococcus aureus infections responsible for many skin disorders, such as acne vulgaris. In this study, solid lipid microparticles are designed as composite vehicles capable of encapsulating a high amount of trans-RSV and enhancing its absorption through the stratum corneum. A microparticulate system based on mixture of PEGylate lipids, long-chain alcohols and LIM is a…
Optimization of local delivery of antifungal agents in the oral cavity by a new formulation
2012
In recent years, with the increased use of antibiotics and immunosuppres-sive agents, there was an increased incidence of oral mycosis and Candida albicans is the most common etiologic agent in oropharyngeal candidiasis, especially in patients with HIV. The aim of this work is to develop a new dosage form containing miconazole (MN) to be topically applied on oral mucosa, allowing for a massive penetration of the drug in the tissue. The vehicle for the drug delivery was lipid microparticles incorporated in a hydrophilic gel. The lipospheres were obtained by hot melt encapsulation method using as matrix ingredients a mixtures of esters of fatty acids with higher fatty alcohols, having low mel…
