Topical delivery is an attractive route for local and systemic treatment. Novel topical application has many advantages like avoids the GI-irritation, prevent the metabolism of drug in the liver and increase the bioavailability of the drug over the conventional dosage forms. The aim of present work was to prepared and characterized erythromycin encapsulated cubosomes using different concentration of glyceryl monooleate and poloxamer 407 by emulsification method. The prepared dispersion of cubosomes was characterized for surface morphology, particle size, entrapment efficiency and in vitro release. Further, optimized formulation was converted to cubosomal gel by incorporating carbopol 934 at different concentrations. The prepared gel was characterized for homogeneity, pH, viscosity, spreadibility, drug content and in vitro drug release study. The result of optimized cubosomes showed average particle size of 264.5±2.84nm and entrapment efficiency about 95.29±1.32 % and the pH of optimized cubosomal was found to be 6.5, viscosity 2475-8901(cp), drug content 95.29% and the spreadibility was found to be 11.74 gm.cm/sec. The in vitro drug release kinetics of optimized formulation was found to follow Korsmeyer peppas model having highest R2 value 0.835 and in vitro drug release of optimized erythromycin loaded cubosomal gel and plain drug gel in 24 hr was found to be 89.91±0.73 and 88.64±2.16, while in 36 hr plain drug gel and cubosomal gel showed drug release about 87.64±0.97 and 91.55±1.09, and sustained release was obtained after 24 hr in case of cubosomal gel.

Optimizing the use of topical retinoids in Asian acne patients.

DOI: 1346-8138.14314  PMID: 29611225   Acne vulgaris is a common disease among people in Asia. International guidelines and treatment recommendations emphasize the central role of topical retinoids in the management of acne. However, topical retinoids remain underutilized in clinical practise, which may be in part due to fear of retinoid-associated dermatitis/lack of experience, particularly in Asian patients. …
