Bigels are unique two-phase systems that have recently been presented as a structured method for active ingredient application. The purposes of the current study were to develop and characterize bigel formulations containing loxoprofen. They benefits both hydrogel organo-gel. In order enhance penetration, pluronic lecithin was added form organo-gel, HPMC hydrogel, which properly hydrates stratu...

Domperidone is practically insoluble prokinetic drug; the systemic bioavailability of the drug following oral administration is only 13-17% because of extensive presystemic metabolism in the gut wall and liver. The applicability of the solid dispersion technique as a method for enhancing absorption of the drug through achieving better dissolution characteristics and better bioavailability for d...

Polyesters are extensively used in drug delivery because of their controllable biodegradation properties and perceived favorable cytocompatibility. However, new ester-based materials are continually being sought which can be produced from readily accessible monomers, which can be tuned for drug encapsulation and which retain good cellular compatibilities. In this study, 5 polyesters of similar ...

The drying of hydrogel films formed by poly(ethylene oxide)-poly(propylene oxide) (PEO-PPO) block copolymers (Pluronic P105 and Pluronic L64) is investigated at various air relative humidity (RH) conditions in the range 11-94%. These amphiphilic block copolymers self-assemble to form a variety of ordered (lyotropic liquid crystalline) structures as the water content decreases. The amount of wat...

The present study investigated the release profiles of insulin from Pluronic F-127 (PF-127) gel containing unsaturated fatty acids such as oleic acid (18:1), eicosapentaenoic acid (20:5) or docosahexaenoic acid (22:6) and the hypoglycemic effect of insulin following the buccal administration of the gel formulations in normal rats. Insulin release from the gels decreased in the presence of unsat...
