Lempuyang gajah rhizome (Zingiber zerumbet (L) Smith is considered potential as larvicidal. A previous study has shown that the purified extract of Z. zerumbet rhizome was toxic against Adese aegypti larvae.  The aim of the study it to formulate a purified extract of Z. zerumbet (L) Smith in granule preparations by combining Sodium starch glycolate, PVP K-30 and tween 80.  The granule formulation was optimized by the Simplex Lattice Design (SLD) method with using Design expert program 7.1.5. The results showed that the interaction of the three components can increase the flow rate index, the angle of repose, and reduce absorption. The optimum formula obtained was Sodium starch glycolate 2%, PVP K-30 2%, and Tween 80 5%. The analysis of one sample t-test shows that there is no significant difference between the predicted parameter values and the experimental results of the flow rate index and angle of repose, while the absorption response is significantly different. The optimum formula for granules has larvicidal activity with 100% larval death during 12-hour treatment.

Furosemide is a potent diuretic drug that has low bioavailability. Furosemide can be formulated into nanoemulsion preparations using the SNEDDS method to increase its bioavailability as SNEDDS can form stable nanoemulsions with droplet sizes 200 nm. This study aims to identify the optimum formula for variations in the concentration of surfactant Tween 80 and cosurfactant PEG 400 based on the characterization tests of emulsification time, percent transmittance, and drug loading. The independent variables used in this study were Tween 80 and PEG 400. Seven furosemide SNEDDS formulas from the Simplex Lattice Design (SLD) method were tested for characterization in the form of emulsification time, percent transmittance, and drug loading. The characterization results were optimized using Simplex Lattice Design. The optimum formula was re-characterized, including emulsification time, percent transmittance, drug loading, particle size, zeta potential, and in vitro dissolution. The results were then compared with theoretical values and analyzed using the One-Sample T-test method. Optimization results showed Tween of 61.4922% and PEG 400 of 18.5078% with the characterization of emulsification time 15.25 seconds, percentage transmittance 94.20%, drug loading 50 100.2 ppm, particle size 12.18 nm. Furthermore, the zeta potential was -17.6 mV, and the in vitro dissolution rate reached 106.71% within 15 minutes.

The aim of this work was to apply the simplex lattice design in the formulation development of lozenges containing Vernonia cinerea extract. The different ratios of three diluents; milk powder, xylitol, and inulin were investigated. The preformulation parameters of powder mixtures were evaluated. The compressed lozenges were evaluated for their weight variation, thickness, hardness, friability, and disintegration time. Results showed that the ratios of the three diluents affected the preformulation parameters. The angle of repose data revealed that all 12 powder mixtures had excellent flow property. The formulation containing milk powder had the highest values of Carr’s index and Hausner ratio, indicating the poor compressibility. While formulation containing inulin had the best compressibility. A formulation containing xylitol had the lowest moisture content. The compressed lozenges had a weight variation of less than 5%, a diameter of 1.5 mm, a thickness of 5-6 mm, and a hardness of 2-12 kP. The 8 of 12 formulations had friability of less than 1%. Use of milk powder provided the longest disintegration time. The desired properties of developed lozenge achieved when the medium amount of xylitol and inulin and low amount of milk powder were used. The optimal diluent ratio providing the weight variation not more than 5%, the hardness of 5-8 kP, friability not more than 1%, and disintegration time not more than 30 min was an equal weight ratio of milk powder, xylitol, and inulin.

Water fraction of binahong (Anredera cordifolia (Ten.) Steen)  leaf has been proven to heal ulcus diabetic. In order to make the use easier and more practical, in this study the water fraction of binahong leaves is formulated in gel preparation form. This study was conducted to obtain a comparison of the amount of sodium alginate and carboxymethyl chitosan as gelling agent to produce gel that meets the good physical requirements. The method used to determine the amount of comparison of sodium alginate and carboxymethyl chitosan is to use Simplex Lattice Design (SLD). Eight variations of gel formula are designed with the ratio of sodium alginate:  carboxymethyl chitosan as follows: F1 (0:3% w/w), F2 (0:3% w/w), F3 (0.75:2.25% w/w), F4 (1.5:1.5 % w/w), F5 (1.5:1.5% w/w), F6 (2.25:0.75% w/w), F7 (3:0% w/w), F8 (3:0% w/w). Physical parameters observed included pH, viscosity, dispersion, and adherence. Data obtained compared with the actual conducted by researchers using one sample test t-test with 95% confidence level. Based on the results of the study, increased sodium alginate concentration can increase viscosity and adhesiveness and decrease the pH and spreadability of the gel. One sample t-test analysis shows that there is no significant difference between predicted parameter value and actual result so SLD equation can be used to construct gel formula of water fraction of binahong leaf. The conclusion is a combination of sodium alginate 1.546% w/w and carboxymethyl chitosan 1.454% w/w yield gel optimum. Physical parameter response of optimum formula is pH 5.86; viscosity 2000 cps; spreadability of 21,96 cm2; and adhesiveness of 19,81 seconds.

Aim: The present research work was carried out to formulate stable fixed dose combination tablets of Bilastine and Montelukast Sodium, used to treat allergic rhinitis associated with asthma and rhino-conjunctivitis on basis of pre and post post-compression parameters evaluation and drug-drug-excipients compatibility studies. Methods: Direct compression methodology was used for tablet production and final composition of drugs and excipients was optimized by evaluating pre and post compression evaluations of blend and tablets respectively. The chemical instability and stability studies were carried out using HPLC method. Results: The Evaluation of pre-compression parameters of batch F1 to F5 shows that as we increase the amount of sodium starch glycolate and colloidal silicon dioxide from F1 to F5, bulk density and tapped density increases slightly whereas the compressibility index and hausner’s ratio of tablets was shifted from excellent to good. Angle of repose shows excellent flow property from F3-F5. After evaluation of post-compression parameters from F1 to F5, there is no significant difference in diameter, thickness and average weight of tablets. The hardness of tablets was decreased slightly from F1 to F5 therefore, the % friability was found to be increased from F1 to F5 and disintegration time was found to be decreased from F1 to F5. Dissolution studies shows % release of Bilastine and Montelukast was increased towards F1 to F5 as the percentage of Sodium Starch Glycolate increases. The drug-drug-excipients compatibility shows that there is no physical and chemical incompatibility between the drug-drug-excipients at accelerated conditions. The stability studies show that % assay of long term and accelerated samples are within 100±2%. Conclusion: The optimized composition found in order to scale up the production of tablets.
