The aim of the study was to develop and evaluate a self- -emulsifying drug delivery system (SEDDS) formulation to improve solubility and dissolution and to enhance systemic exposure of a BCS class II anthelmetic drug, albendazole (ABZ). In the present study, solubility of ABZ was determined in various oils, surfactants and co-surfactants to identify the microemulsion components. Pseudoternary phase diagrams were plotted to identify the microemulsification existence area. SEDDS formulation of ABZ was prepared using oil (Labrafac Lipopfile WL1349) and a surfactant/ co-surfactant (Tween 80/PEG 400) mixture and was characterized by appropriate studies, viz., microemulsifying properties, droplet size measurement, in vitro dissolution, etc. Finally, PK of the ABZ SEDDS formulation was performed on rats in parallel with suspension formulation. It was concluded that the SEDDS formulation approach can be used to improve the dissolution and systemic exposure of poorly water-soluble drugs such as ABZ.

Objective: Cancer is the deadliest disease affecting the life of the people all around the world. Colon cancer is the cancer which is affecting the colon region it is the last part of the gastrointestinal tract which is mainly responsible for the absorption of water and minerals from the food debris. Colon cancer is the second most cancer creating death in the world. It affects both male and female equally. Curcumin is a flavonoid used from decades for the treatment of various ailments including cancer. This present work is to formulate Self-nanoemulsifying drug delivery (SNEDDS) system with the help of curcumin for colon delivery. Materials and Methods: Nanoemulsion was prepared using the curcumin pre-concentrated self-nanoemulsifying drug delivery system, with which tablets were prepared and coated with pectin followed by the evaluation test such as in vitro dissolution and cell line studies. Results: Solubility profile of curcumin was found with a greater impact using Capmul MCM and Labrafac PG which is then added with the surfactants and co-surfactants and were converted into Nano-droplets. F1 formulation was selected after carrying out the characterisation studies and converted into a tablet dosage form and then coated with pectin, in vitro studies depicted a release of 80% in pH 6.8. Conclusions: Formulation of a solid self-Nano emulsifying drug delivery system using curcumin was successfully carried out. From the results obtained, the formulation (F1) was selected for the formation of the tablets and the further experimental part is carried out. The tablet dosage form is then coated with pectin and used for targeting the colon cancer cells for its treatment.

Background: The study was aimed to prepare and evaluate tamoxifen loaded controlled release liposomes to reduce the side effects of tamoxifen during cancer treatment.  Methods: Different tamoxifen loaded liposomes were prepared by modified ether injection (MEIM) and thin film hydration method (TFHM) under prescribed conditions. The prepared liposomes were characterized by using optical microscopy, evaluating encapsulation efficiency, in-vitro and ex-vivo diffusion studies by using dialysis membrane and chicken intestinal sac respectively. Results: The data revealed that all of the liposomes were spherical in shape and stable under three physical conditions i.e. 4, 25 and 37 ± 2°C temperatures and 60 ±5% relative humidity. Additionally most of the liposomes followed zero order and class II release kinetics. It was also observed that with the increase of phospholipids and cholesterol, entrapment efficiency of liposome vesicles increased thus giving a controlled release drug delivery system but further increase reduced this efficiency at a certain level. Conclusion: The formulated control release liposomes might be a good drug delivery system for target oriented drug delivery with minimum side effects of tamoxifen during cancer treatment.
