The aim of the present study was to design a novel topical skin-target drug-delivery system, the paeonol microsponge, and to investigate its drug-release patterns in dosage form, both in vitro and in vivo. Paeonol microsponges were prepared using the quasi-emulsion solvent-diffusion method. In vitro release studies were carried out using Franz diffusion cells, while in vivo studies were investi...

Microsponge were prepared by liquid-liquid suspension polymerization of styrene and methyl methacrylate. Microsponges were dispersed in gel prepared by using carbopol 940 and evaluated for drug release using Franz diffusion cell. Free flowing powder with size distribution 30 to 107 μm was obtained. The average drug release from the gels containing microspongic fluconazole was 67.81% in 12 h. dr...

Background. Oxybenzone, a broad spectrum sunscreen agent widely used in the form of lotion and cream, has been reported to cause skin irritation, dermatitis, and systemic absorption. Aim. The objective of the present study was to formulate oxybenzone loaded microsponge gel for enhanced sun protection factor with reduced toxicity. Material and Method. Microsponge for topical delivery of oxybenzo...

The aim of the present study was to develop and evaluate microsponge based topical delivery system of acyclovir for sustained and enhanced drug deposition in the skin. Microsponges containing acyclovir were prepared by an emulsion solvent diffusion method. The effect of formulation variable such as drug: polymer ratio, stirring speed, internal phase on the physical characteristics of microspong...

Objective: The objective of the present study was to compare release effect Luliconazole from different polymeric (Hydrophilic and Hydrophobic) microsponges prepared using varying concentrations. best microsponge selected incorporated into gel (Natural synthetic) drug is determined compared with marketed formulation.
 Methods: Polymers such as EC, HPMC, Eudragit RSPO PVA emulsifier, solven...

We present an observational sign that ensures perfect alignment during femtosecond laser-assisted in situ keratomileusis (FS LASIK). Alignment is assured when a microsponge is used to dry the flap and the area of dryness exceeds the area of direct touch of the microsponge. The area might even reach the whole circumference of the flap at the first touch. This sign of alignment can be explained b...

The objective of present work was to formulate and evaluate Fluconazole (FLZ) microsponges using quasi emulsion solvent diffusion technique and microsponge gel by using carbopol. Microsponges containing FLZ were obtained successfully with different proportions of ethyl cellulose polymer (EC). The formulations were studied for particle size and physical characterization. The physical characteriz...

In the field of drug delivery system, there are numerous new formulation techniques. Microsponge one most recent novel technique which gaining popularity now days due to their use controlled release and targeted system. technology offers entrapment ingredient is believed contribute towards reduced side effect, improved stability, increase elegance enhanced flexibility. addition, microsponges no...

OBJECTIVE The rationale behind present research vocation was to develop and investigate a novel microsponge based gel as a topical carrier for the prolonged release and cutaneous drug deposition of fluconazole (FLZ); destined for facilitated fungal therapy. MATERIALS AND METHODS Microsponges were prepared using quasi-emulsion solvent diffusion method using Eudragit S-100. In the direction of ...

Antisense oligonucleotides can be employed as a potential approach to effectively treat cancer. However, the inherent instability and inefficient systemic delivery methods for antisense therapeutics remain major challenges to their clinical application. Here, we present a polymerized oligonucleotides (ODNs) that self-assemble during their formation through an enzymatic elongation method (rollin...
