This article describes current strategies to enhance aqueous solubility and dissolution rate of poor soluble drugs. Most drugs in the market are lipophilic with low or poor water solubility. There are various methods to enhance solubility: co-solvency, particle size reduction, salt formation and Self Nanoemulsifying drug delivery systems, SEDDS is a novel approach to enhance solubility, dissolution rate and bioavailability of drugs. The study involves formulation and evaluation of solid self-Nano emulsifying drug delivery system (S-SNEDDS) to enhance aqueous solubility and dissolution rate. Oral route is the most convenient route for non-invasive administration. S-SNEDDS has more advantages when compared to the liquid self-emulsifying drug delivery system. Excipients were selected depends upon the drug compatibility oils, surfactants and co surfactants were selected to formulate Liquid SNEDDS these formulated liquid self-nano emulsifying drug delivery system converted into solid by the help of porous carriers, Melted binder or with the help of drying process. Conversion process of liquid to solid involves various techniques; they are spray drying; freeze drying and fluid bed coating technique; extrusion, melting granulation technique. Liquid SNEDDS has a high ability to improve dissolution and solubility of drugs but it also has disadvantages like incompatibility, decreased drug loading, shorter shelf life, ease of manufacturing and ability to deliver peptides that are prone to enzymatic hydrolysis.

Objective: To enhance solubility and dissolution rate of budesonide through development of solid self-nanoemulsifying drug delivery system (S-SNEDDS). Methods: Liquid self-nanoemulsifying drug delivery systems (L-SNEDDS) were prepared and ternary phase diagram was constructed using Origin pro 8. Liquid self-nanoemulsifying formulation LF2 having 20% oil and 80% of surfactant/co-surfactant was optimized from the three formulations (LF1-LF3) to convert in to solid, through various characterization techniques like self-emulsification, in vitro drug release profile and drug content estimation. The prepared L-SNEDDS converted into S-SNEDDS, SF1-SF6 by adsorption technique using Aerosil 200, Neusilin US2, and Neusilin UFL2 to improve flowability, compressibility and stability. Results: Formulation LF2 exhibited globule size of 82.4 nm, PDI 0.349 and Zeta potential -28.6 mV with drug indicating the stability and homogeneity of particles. The optimized formulation SF4 containing Neusilin UFL2 was characterized by DSC, FTIR, X-Ray diffraction studies and found no incompatibility and no major shifts were noticed. Formulation SF4 released 100 % drug in 20 min against pure drug release of 47 % in 60 min. Regardless of the form (i.e. liquid or solid) similar performance of emulsification efficiency is observed. Conclusion: The results demonstrated that the technique of novel solid self-nanoemulsifying drug delivery system can be employed to enhance the solubility and dissolution rate of poorly water-soluble drug budesonide.

Objective: The main objective of this study was to preparation and evaluation of efavirenz (EFV) to enhance its solubility and dissolution rate by self-emulsifying drug delivery system. Methods: EFV self-emulsifying drug delivery systems (SNEDDS) were formulated using different oils, surfactant, and co-surfactant. Peceol, Tween 20, and Capmul MCM were used as oil, surfactant, and co-surfactant, respectively, followed by the evaluation by the performance of different tests such as visual observation, solubility studies, thermodynamic stability study, transmittance studies, drug content, and in-vitro release study. Results: Fourier-transform infrared studies revealed negligible drug and polymer interaction. From the phase diagram, it was observed that self-emulsifying region was enhanced with increasing surfactant and co-surfactant concentrations with oil. F13 was selected as optimized formulation on the basis of physicochemical parameters, particle size, and in-vitro dissolution studies with the release of 98.39±5.10% drug in 1 hour. The optimized formulation size was found to be 156.7 nm as mean droplet size and Z-Average of 808.6 nm with -18.3 mV as zeta potential. Conclusion: The study demonstrated that SNEDDS was a promising strategy to enhance the dissolution rate of EFV by improving solubility.

Present research work was aimed to enhance aqueous solubility and dissolution rate of olanzapine by solid self nano emulsifying drug delivery system(S-SNEDDS). Olanzapine is a BCS class II drug having 65% oral bioavailability; it is used in the treatment of psychosis, depression and mania conditions. Oils, Surfactants, Co surfactants were selected depending upon the saturated solubility of olanzapine in those components; excipients were screened depending on olanzapine solubility in various oils, surfactants and co surfactants. Surfactant: co surfactant {Smix} ratios i.e., 3:1 and 4:1 were prepared to determine nano emulsion regions and also to formulate liquid self nano emulsifying drug delivery system (L-SNEDDS). Pseudo ternary phase diagram were plotted by using Triplot version 4.1.2 software, nano emulsion region was determined and evaluated. Formulations were designed based on saturated solubility of olanzapine and Pseudo ternary phase diagram using various ratios of oils [Capryol 90], surfactants [Kolliphor EL], co surfactants [Lauroglycol 90] depending on its solubility and nano emulsion formation four formulations were developed which are further selected for characterisation of L-SNEDDS like robustness to dilution, self emulsification, determination of droplet size, PDI, Drug loading efficacy, zeta potential and also Invitro drug release. Among those four formulations, F1 (SB184J 4:6) was optimum because compared to other three formulations F3 gave best results in terms of droplet size (66nm) with PDI (0.24), Invitro drug release, dissolution rate of F1 SNEDDS having (88.201± 0.25%). Invitro drug release of F1 formulation was compared with that of Olanzapine [API] (45.281± 0.52%) the results indicating that there is a increase in solubility and dissolution rate of olanzapine by 2.2 times more compared to pure olanzapine (API). F1 (SB184J 4:6) were converted into S-SNEDDS by adsorption process by addition porous carriers (Aerosil 200). Formulated S-SNEDDS were undergone various evaluation parameters and also reconstitution parameters to determine Droplet size and Invitro drug release of solid F1 (SB184J4:6) formulation. The results of present study demonstrates that olanzapine SNEDDS has an ability and potential to enhance solubility and dissolution rate.
