Formulation and Preparation of Felodipine Nanoemulsions
نویسندگان
چکیده
The objective of present work was development of felodipine nano emulsion formulations using sesame oil as sole lipid phase by high pressure homogenization technique. A combination of non-ionic surfactants was used based on HLB (Hydrophilic lipophilic balance) values. The resultant nano emulsions were characterized for particle size, zeta potential. The particle size for the optimized nano emulsions was 162.7±8.1 and zeta potential was -37.5±5.2. Percentage drug content was found to be 79.56±1.43%. Centrifugation and freeze – thaw cycling showed no signs of creaming.

Response surface methodology was employed to study the effect of formulation composition variables, water content (60%-80%, w/w) and oil and surfactant (O/S) ratio (0.17-1.33), as well as high-shear emulsification conditions, mixing rate (300-3,000 rpm) and mixing time (5-30 minutes) on the properties of sodium diclofenac-loaded palm kernel oil esters-nanoemulsions. The two response variables w...

Brinzolamide (BZ) is an intraocular pressure reducing agent with low bioavailability. The purpose of the present study was to overcome this issue by development of BZ containing nanoemulsions (NEs) as an ocular drug delivery system with desirable therapeutic efficacy. Brinzolamide NEs were prepared by the spontaneous emulsification method. Based on initial release studies, twelve formulations w...
متن کاملCurrent State of Nanoemulsions in Drug Delivery
Nanoemulsions have attracted great attention in research, dosage form design and pharmacotherapy. This is as a result of a number of attributes peculiar to nanoemulsions such as optical clarity, ease of preparation, thermodynamic stability and increased surface area. Nanoemulsions also known as submicron emulsions serve as vehicles for the delivery of active pharmaceutical ingredients as well a...
متن کاملA Detailed Review on Nanoemulsion Drug Delivery System
Nanoemulsions are submicron sized emulsions that are under investigation as drug carriers for improving the delivery of therapeutic agents. These are the thermodynamically stable isotropic system in which two immiscible liquids are mixed to form a single phase by means of appropriate surfactant and cosurfactant. Nanoemulsion droplet sizes fall typically in the range of 20200nm and shows narrow ...
