OBJECTIVES In situ formation of nanocrystals and dissolution profiles of fenofibrate (FFB) from a self-microemulsifying drug delivery system (SMEDDS) were characterized. METHODS SMEDDS formulated with Myritol and surfactant mixture (Smix) of D-α-Tocopheryl polyethylene glycol 1000 succinate (TPGS) and either Tween 20 (A, C, E, G, M, S, N, T, O) or Tween 80 (B, D, F, H, P, U, Q, V, R) at vario...
Alginate-based composite sponges were developed as carriers to prolong the gastric retention time and controlled release of curcumin-loaded self-microemulsifying drug delivery systems (Cur-SMEDDS). Liquid Cur-SMEDDS was incorporated into a solution made up of a mixture of polymers and converted into a solid form by freeze-drying. The ratio of alginate as the main polymer, adsorbent (colloidal s...
The supersaturatable self-microemulsifying drug delivery system (S-SMEDDS) represents a new thermodynamically stable formulation approach wherein it is designed to contain a reduced amount of surfactant and a water-soluble polymer (precipitation inhibitor or supersaturated promoter) to prevent precipitation of the drug by generating and maintaining a supersaturated state in-vivo. The supersatur...
Oral route is the most preferred route of drug administration due to its easy accessibility, intake, and wide range of choices making it economical. Currently, greater than 60% of marketed drugs are oral products. Over 90% of therapeutic compounds given orally areknown to possess oral bioavailability limitations. Therefore, there is a need to explore various approaches that can be used to impro...
Self-microemulsifying drug delivery system (SMEDDS) of lovastatin was aimed at overcoming the problems of poor solubility and bioavailability. The formulation strategy included selection of oil phase based on saturated solubility studies and surfactant and co-surfactant screening on the basis of their emulsification ability. Ternary phase diagrams were constructed to identify the self-emulsifyi...
The majority of drugs have a low dissolution rate, which is a limiting step for their absorption. In this manuscript, solid dispersions (SD), solid self-microemulsifying drug delivery systems (S-SMEDDS) and solid self-nanoemulsifying drug delivery systems (S-SNEDDS) were evaluated as potential formulation strategies to increase the dissolution rate of carbamazepine. Influence of increased disso...
To assess the comparative bioavailability of two cyclosporine capsule products with different pharmaceutical formulation an open randomized two-period cross over study was conducted in 24 healthy volunteers. Our results, obtained from cyclosporine HPLC determination onto the whole blood samples collected, show that the test cyclosporine non-SMEDDS formulation was not bioequivalent cyclosporine ...
Olmesartan medoxomil (OLM) is an angiotensin II receptor blocker (ARB) antihypertensive agent administered orally that has absolute bioavailability of only 26% due to the poor aqueous solubility (7.75 μg/ml). The aim of the present investigation was to develop a self-microemulsifying drug delivery system (SMEDDS) to enhance the oral absorption of OLM. The solubility of OLM in various oils, surf...
In this study, various formulations of solidified carvedilol-loaded SMEDDS with high loading (up to 67% w/w) were produced the spray drying process using porous silica-based carriers. The yield was improved higher atomization gas flow rate during and prolonged mixing time dispersion liquid solid carriers prior process. Depending on choice carrier SMEDDS:carrier ratio in SMEDDS, different drug l...
