Abstract
The delivery of antihistaminic agents via the oral route is problematic, especially for elderly patients. This study aimed to develop a sublingual formulation of promethazine hydrochloride by direct compression, and to mask its intensely bitter taste. Promethazine hydrochloride (PMZ) sublingual tablets prepared by direct compression were optimized using Box-Behnken full factorial design. The effect of a taste-masking agent (Eudragit E 100, X1), superdisintegrant (crospovidone; CPV, X2) and lubricant (sodium stearyl fumarate; SSF, X3) on sublingual tablets’ attributes (responses, Y) was optimized. The prepared sublingual tablets were characterized for hardness (Y1), disintegration time (Y2), initial dissolution rate (IDR; Y3) and dissolution efficiency after 30 min (Dissolution Efficiency (DE); Y4). The obtained results showed a significant positive effect of the three independent factors on tablet hardness (P < 0.05), and the interactive effect of Eudragit E 100 and CPV on tablet hardness was significant. Disintegration time was mainly affected by Eudragit E 100 and CPV concentrations. Moreover, IDR was employed to assess the taste masking effect, lower values were obtained at higher Eudragit E 100 concentration despite it was statistically insignificant (p > 0.05). Optimized formulation that was suggested by the software was composed of: Eudragit E 100 (X1) = 2.5% w/w, CPV (X2) = 4.13% w/w, and SSF (X3) = 1.0% w/w. The observed values of the optimized formula were found to be close to the predicted optimized values. The Differential Scanning Calorimetric (DSC) studies indicated no interaction between PMZ and tablet excipients.

Abstract
Pioglitazone (PGZ) is an oral antidiabetic agent that increases cell resistance to insulin, thereby decreasing blood glucose levels. PGZ is a class II drug. Because of its pH-dependent solubility, it precipitates at the intestinal pH, resulting in an erratic and incomplete absorption following oral administration, which causes fluctuations in its plasma concentration. A nanoparticle drug delivery system offers a solution to enhance the dissolution rate of this poorly water-soluble drug. PGZ nanoparticles were formulated by the wet milling technique using a planetary ball mill. The effects of the steric stabilizer (Pluronic F-127, PL F-127), electrostatic stabilizer (sodium deoxycholate, SDC), and number of milling cycles were optimized using a Box-Behnken factorial design. The results showed that the ratio of PL F-127: SDC significantly affected the zeta potential and the dissolution efficiency (DE%) of PGZ. The optimized PGZ nanoparticle formulation enhanced the dissolution to reach 100% after 5 min. The in-vivo results showed significant enhancement in Cmax (1.3-fold) compared to that of the raw powder, and both AUC0-24 and AUC0-∞ were significantly (p < 0.05) enhanced. In conclusion, PGZ nanoparticle formulation had enhanced dissolution rate in the alkaline media, which improved its drug bioavailability relative to that of the untreated drug.

Abstract
Purpose Rosuvastatin calcium (ROSCa) nanoparticles were fabricated by planetary ball mill to enhance ROSCa dissolution rate and bioavailability. Methods Milling time factors (milling cycle time and number as well as pause time) were explored. The effect of different milling ball size, speed, and solid-to-solvent ratio were also studied using Box-Behnken factorial design. The fabricated nanoparticles were evaluated in term of physicochemical properties and long-term stability. Results The obtained data revealed that the integrated formulation and process factors should be monitored to obtain desirable nanoparticle attributes in terms of particle size, zeta potential, dissolution rate, and bioavailability. The optimized ROSCa nanoparticles prepared by milling technique showed a significant enhancement in the dissolution rate by 1.3-fold and the plasma concentration increased by 2-fold (P<0.05). Moreover, stability study showed that the optimized formula of ROSCa nanoparticles exhibits higher stability in long-term stability conditions at 30°C with humidity of 60%. Conclusion Formulation of ROSCa as nanoparticles using milling technique showed a significant enhancement in both dissolution rate and plasma concentration as well as stability compared with untreated drug.

Abstract
Apigenin (APG) is a poorly soluble bioactive compound/nutraceutical which shows poor bioavailability upon oral administration. Hence, the objective of this research work was to develop APG solid dispersions (SDs) using different techniques with the expectation to obtain improvement in its in vitro dissolution rate and in vivo bioavailability upon oral administration. Different SDs of APG were prepared by microwave, melted and kneaded technology using pluronic-F127 (PL) as a carrier. Prepared SDs were characterized using "thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), Fourier transform infra-red (FTIR) spectrometer, powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM)". After characterization, prepared SDs of APG were studied for in vitro drug release/dissolution profile and in vivo pharmacokinetic studies. The results of TGA, DSC, FTIR, PXRD and SEM indicated successful formation of APG SDs. In vitro dissolution experiments suggested significant release of APG from all SDs (67.39-84.13%) in comparison with control (32.74%). Optimized SD of APG from each technology was subjected to in vivo pharmacokinetic study in rats. The results indicated significant improvement in oral absorption of APG from SD prepared using microwave and melted technology in comparison with pure drug and commercial capsule. The enhancement in oral bioavailability of APG from microwave SD (319.19%) was 3.19 fold as compared with marketed capsule (100.00%). Significant enhancement in the dissolution rate and oral absorption of APG from SD suggested that developed SD systems can be successfully used for oral drug delivery system of APG.

Abstract
Purpose Rosuvastatin calcium (ROSCa) is a poorly soluble drug with bioavailability not exceeding 20%. Decreasing the particle size may enhance its solubility, dissolution rate and bioavailability. Therefore, the aim of the current study is to prepare ROSCa nanoparticles by wet milling technique using planetary ball mill. The codesign between formulation and stabilization of nanoparticles was studied to achieve both high dissolution as well as bioavailability. Methodology ROSCa nanosuspensions was prepared by wet milling technique using planetary ball mill, by applying milling ball size of 0.1 mm at speed of 800 rpm for 3 cycles each cycle composed of 10 minutes. HPMC, PVP k-30, pluronic F-127, Tween 80 and PEG 6000 were used as stabilizers. The nanosuspensions were then freeze-dried, and the dried nanoparticles were evaluated for particle size, zeta potential, in-vitro dissolution test, XRPD and in-vivo study. Results ROSCa nanoparticles stabilized with 10% PVP (P3) had a good stability with smallest particle size, which in turn enhanced the dissolution rate. The particle size of the leading formula was 461.8 ± 16.68 nm with zeta potential of -31.8 ± 7.22 mV compared to untreated drug that has a particle size of 618μm. The percent of ROSCa dissolved after 1 hour enhanced significantly which reached 72% and 58.25% for leading nanoparticle formula and untreated ROSCa, respectively (P < 0.05). The in-vivo study of ROSCa from the leading nanoparticle formula showed a significant enhancement in the Cmax after 2 h (82.35 ng/ml) compared to 9.2 ng/ml for untreated drug. Conclusion Wet milling technique is a successful method to prepare ROSCa nanoparticles. From different stabilizer used, PVP (10%) was able to produce stable nanoparticle with small particle size which significantly enhance the dissolution rate and pharmacokinetics parameters of ROSCa.
