SOLID SMEDDS THESIS

Solubility study also indicated that FK has poor aqueous solubility and was independent of pH of the medium. Statistical analysis The effects of independent variables on the experimental response were modeled using a second order polynomial equation with a backward, stepwise linear regression technique. More importantly the large quantity of surfactants in the formulations can induce GI irritations. The improved therapeutic efficacy could be primarily because of increased solubility and dissolution rate of FK leading to its rapid and efficient dispersion in GI tract. Recently the liquid nanoemulsifying drug delivery systems SNEDDS have shown dramatic effects on improving oral bioavailability of poorly soluble drugs. Then the rotated SE pellets were sieved by mesh 60 sieve and weighed in order to determine friability.

Based on previous studies, 18 a self-emulsifying system was prepared containing a fixed proportion of loratadin 0. In contrast, Carbitol and propylene glycol, short chain amphiphiles, can penetrate perfectly at interface. Details of shape analysis results are brought in Table 3. Drug and excipients Sr. The pellets were produced by the following processes:

Effect of FK loading on physical stability of microemulsions was studied using optimized composition i.

Carbitol and propylene glycol, hydrophilic cosurfactants increased spontaneity of microemulsion formation. In this study, we intended to prepare and characterize solid self-nanoemulsifying drug delivery system for oral delivery of loratadin as the model insoluble drug.

Microemulsion formulation for enhanced absorption of poorly soluble drugs I. Pharmacodynamic Evaluation In Mice Immunosuppressant effect of FK is due to its selective and reversible inhibition of T lymophocytes, preventing formation of interleukins that are responsible for T-cell activation and proliferation.

Quality assessment of the produced pellets was made by evaluating their size and shape, 22 and percentages of the SE pellets in the sieve fraction are shown in Table 3. Preparation and evaluation of the self-emulsifying drug delivery system containing loratadine.

Thus, the study gave an insight into relative emulsification properties of SMEDDS components and forms the basis of their selection. Mice were administered formulations equivalent to 3. Improved oral bioavailability of artemisinin through inclusion complexation with beta- and gamma-cyclodextrins. Optimum SNE pellet formulations were then selected and their in-vitro drug release was evaluated in comparison with liquid SEDDS, conventional loratadin tablets and pellets. Oral delivery of liposomal tacrolimus: The resulting SNE pellets exhibited uniform size and shape.

Thus, it was thought that, combination of above factors smeedds result in an increase in rate and extent of absorption of FK leading to its improved therapeutic efficacy over commercial formulation.
