vitamin e (α-tocopherol) is a natural antioxidant very useful for preventing the harmful effects of uv sun rays as skin aging and cancers. in this study, different mlv formulations were made using egg lecithin and varying molar ratios of α-tocopherol and/or cholesterol, and their encapsulation efficiencies were determined. the best liposomal product was incorporated into a carbomer 980 gel. the...

background the increased incidence of fungal resistance has necessitated the need to search for new antifungal agents. objective the main objectives of the present study were to investigate the effectiveness of the essential oil of eucalyptus camaldulensis on dermatophytes growth and to formulate and characterize a liposomal gel loaded with the essential oil. materials and methods the essential...

Possible leakage of 5-fluorouracil from stable plurilamellar vesicles was monitored during storage of the liposomal concentrates, gels and lyophilized powders. Changes in release profile of dibucaine were taken as indicator of instability. Release profiles were obtained using the dialysis technique for a freshly prepared liposomal concentrate, gel or reconstituted lyophilized powder (zero time)...

Liposomal carriers, eminent for their potential in topical drug delivery have been chosen to help embedding of nystatin molecules in the skin layers. The objective of present study was to develop and carry out rheological investigations of nystatin liposomal gel by using optimization technology in terms of 2 factorial design. In this study attempts have been made to formulate liposomal dispersi...

Arthritis is a major cause of disability and morbidity, particularly in older individuals. The symptoms and signs of arthritis and related conditions include pain, stiffness, swelling, muscle weakness, and limitation of movement of the joints. The objective of the present work was to provide a dosage form for localized action of drugs used in treatment of arthritis to the affected tissues for p...

Liposomal encapsulation is known to signifi cantly improve the therapeutic index of a drug. In the present investigation liposomal formulations were chosen to transport clindamycin, which is considered as the most effective topical antibiotic for acne, into the skin layers. Liposomes with clindamycin phosphate were prepared using lipid fi lm hydration method and the optimum ratio of the compone...

BACKGROUND Peripheral opioid receptor targeting has been well established as a novel target in clinical pain management for acute and chronic peripheral inflammatory pain. The physiochemical properties of the peripheral mu-opioid receptor agonist, loperamide HCl, limit the use of the free drug as an analgesic or anti-inflammatory agent, particularly for dermal delivery across intact skin. OBJ...

PURPOSE To develop an in situ gel system comprising liposome-containing paclitaxel (PTX) dispersed within the thermoreversible gel (Pluronic® F127 gel) for controlled release and improved antitumor drug efficiency. METHODS The dialysis membrane and membrane-less diffusion method were used to investigate the in vitro drug release behavior. Differential scanning calorimetry (DSC) thermal analys...

This study evaluates the prophylactic effect of the peripherally-selective mu-opioid receptor agonist, loperamide, administered topically in a liposomal gel formulation on pain, inflammation, and disease progression in the adjuvant-induced model of experimental rheumatoid arthritis in female Lewis rats. In a randomized, blinded and controlled animal trial, AIA rats were divided into six groups ...

cyproterone acetate (ca) has been loaded to liposome by solvent evaporation and thin film formation technique. the effects of some formulation variables such as temperature of organic solvent evaporation, rotary evaporator speed, volume of organic solvent, volume of balloon and temperature of hydrating buffer has been evaluated. the data showed that bigger balloon with higher surface area has b...
