The available range of phytopreparations for topical use in the oral cavity does not fully meet the needs of patients as mainly medicinal plant raw materials and tinctures of domestic production represent it. Therefore, we developed a pharmaceutical composition in the form of tablets based on dry extracts herb of Geranium sanguineum L., Geranium sibiricum L. and essential oil of Salvia sclare. To optimize the composition of the tablets it is necessary to study and select the necessary excipients and their quantities, which was the purpose of the work. In order to study the influence of 10 quantitative factors on the properties of powder masses and the main quality indicators of tablets with plant extracts and essential oil, the method of random balance was used. The obtained powder mixtures and tablets based on them were subjected to the determination of the following pharmaco-technological parameters: bulk density, tapped density, flowability, the angle of repose, the uniformity of weight, tablet hardness testing, the friability test, disintegration time, desirability function. The pharmaco-technological index of bulk density improves with an increase in the amount of Pregelatinized Starch, Mannitol 60, Emcompress, as well as a decrease in the amount of Neusilin UFL2 and Neusilin US2. Regarding the tapped density, Neusilin US2 significantly affects it, with the increase of which this indicator decreases. With the introduction of more Neusilin US2, Mannitol 60, Pregelatinized Starch, Ludipress, Emcompress and Magnesium Stearate, the value of the angle of repose is improved. The average mass has the greatest influence on fluidity, at its decrease this indicator improves. The same happens with the introduction of Neusilin UFL2, Neusilin US2, Pregelatinized Starch and Magnesium Stearate. The uniformity of weight of all series of tablets fluctuates within ± 5%, and friability to 1%, which meets the requirements of the State Pharmacopoeia of Ukraine. Also, despite the results obtained, all series of tablets were very strong, with the lowest tablet hardness testing – 159 N. The disintegration of the tablets varies within 6 minutes. After evaluating the results of the scattering diagrams of all pharmaco-technological parameters as well as the desirability function, Neusilin US2, МCC 102, Sodium croscarmellose, Mannitol 60 and Magnesium Stearate were selected for further research. The average weight of tablets should be increased to 0.55 g.

BACKGROUND: Pugun tano extract had been studied for its effect as hepatoprotector. However, the usage of the plant in the form of extract has a limitation, especially if the extract is consumed by the people due to the unpleasant taste and odour. Then, the extract needs to be transformed into a particular dosage form, such as a capsule. But before the capsule can be produced, a preformulation study of pugun tano extract into a granule mass in capsule need to be evaluated. AIM: The study aimed to formulate the ethanolic extract of pugun tano (Curanga fel-terrae (Lour.) Merr) as granule mass in the capsule dosage form. METHODS: The pugun tano ethanolic extract was formulated in several steps included preparation of dry extract using coating method with polyvinylpyrrolidone (PVP) and granule mass production. The excipients used for the granule mass were lactose granules (made with tapioca starch using wet granulation), corn starch (made with 3 concentrations of 5% (F1), 7.5% (F2) and 10% (F3)), talcum, magnesium stearate, methylparaben, and propylparaben. The granule mass was evaluated for the bulk density, tapped density, inter-particle porosity, Carr’s index, Hausner ratio, angle of repose, and flowability. RESULTS: The results showed that all of the formulae passed the requirement of the preformulation test. The bulk density of the granule mass was 0.79 – 0.86 g/ml; the tapped density was 0.88 – 0.90 g/ml; the inter-particle porosity was 0.03 – 0.14; the Carr’s index was 2.71 – 11.94%; the Hausner ratio was 1.09-1.12; the angle of repose was 26.10 – 28.90°; and the flowing time was 5.97 – 6.63 seconds.

Background: Developing a new excipient and obtaining its market approval is an expensive, time-consuming and complex process. Compared to that, the co-processing of already approved excipients has emerged as a more attractive option for bringing better characteristic excipients to the market. The application of the Design of Experiments (DoE) approach for developing co-processed excipient can make the entire process cost-effective and rapid. Objective: The aim of the present investigation was to demonstrate the applicability of the DoE approach, especially 32 full factorial design, to develop a multi-functional co-processed excipient for the direct compression of model drug - cefixime trihydrate using spray drying technique. Methods: The preliminary studies proved the significant effect of atomization pressure (X1) and polymer ratio (microcrystalline cellulose: mannitol - X2) on critical product characteristics, so they were selected as independent variables. The angle of repose, Carr’s index, Hausner’s ratio, tensile strength and Kuno’s constant were selected as response variables. Result: The statistical analysis proved a significant effect of both independent variables on all response variables with a significant p-value < 0.05. The desirability function available in Design Expert 11® software was used to prepare and select the optimized batch. The prepared co-processed excipient had better compressibility than individual excipients and their physical mixture and was able to accommodate more than 40 percent drug without compromising the flow property and compressibility. Conclusion: The present investigation successfully proved the applicability of 32 full factorial design as an effective tool for optimizing the spray drying process to prepare a multi-functional co-processed excipient.

Background: In the previous study, investigators have synthesized acrylamide grafted and carboxymethylated derivatives of neem gum and evaluated their potential in the formulation of nanoparticles. In continuation of previous work, authors have evaluated neem gum polysaccharide (NGP), acrylamide grafted neem gum polysaccharide (NGP-g-Am) and carboxymethylated neem gum polysaccharide (CMNGP) as binding agent in the tablet dosage form. Methods: Diclofenac sodium was used as a model drug while microcrystalline cellulose and talc were used as excipient in the preparation of granules employing wet granulation technique. NGP, NGP-g-Am and CMNGP were utilized as binding agent in the preparation of granules. Prepared granules were characterized for various pre-compression and post-compression parameters. Results and Discussion: Binding agents were used in the concentration of 4-24%w/w. NGP incorporated granules showed more bulk density and lower values of tapped density, Carr’s index, bulkiness, Hausner’s ratio and angle of repose as compared to NGP-g-Am consisting granules. NGP-g-Am consisting tablets showed more hardness and zero friability as compared to NGP based tablets. Drug content was found lower for the tablets having grafted polymer in place of NGP. CMNGP were also utilized to prepare granules but granules were not be able to compress keeping all the compacting parameters same as used in the case of NGP and NGP-g-Am consisting granules. NGP and NGP-g-Am were able to sustain drug release up to 6 and 8 h, respectively. Conclusion: It can be concluded that NGP-g-Am induces better properties when used as a binder in the tablet formulation than native polymer, while CMNGP cannot be utilized as a binding agent in the preparation of a tablet.

Ukraine has one of the highest mortality rates from cardiovascular diseases in Europe, accounting for 772.1 cases among men and 440.9 among women per 100 000 population. Antihypertensive drugs are different in dose, active substance and mechanism of action. Monotherapy is ineffective in most cases, therefore it requires a combination of several substances from different pharmacotherapeutic groups. Enalapril and amlodipine are the most often included in treatment regimens for hypertension. Therefore it is advisable to develop combined tablets with enalapril and amlodipine. The aim of the work was to study the effects of excipients on the pharmaco-technological parameters of intermediates and tablets with enalapril and amlodipine. During the work the studied excipients were grouped into 6 factors according to their functional purpose. The experiment was based on the method of mathematical planning. The tablets were preparated by compression after wet granulation. The studies were carried out according to pharmacopoeial methods. Statistical data processing was performed by dispersion analysis. During the experiment it was studied the effects of 30 excipients on the pharmaco-technological properties of granules (loss on drying), tablet mass (fluidity, angle of inclination, bulk density, tapped density) and tablets (uniformity of mass, hardness, friability and disintegration). The effect of 6 qualitative factors on the main reviews (indicators) of granules, powder masses and tablets with enalapril and amlodipine was studied. It is showed by ranked rows of advantages for the influence of excipients on 10 reviews (indicators) of granules, powder masses and tablets with enalapril and amlodipine. As a result of the study, the effects of excipients on the pharmaco-technological parameters of intermediates and tablets with enalapril and amlodipine were studied.

Ibuprofen is one of the common NSAIDs having poor water solubility, low dissolution, weak flow properties and reduced compressibility. These downsides of ibuprofen crystal upraise crucial challenges during development of a dosage form. The aim of this present work was to modify the physical form of ibuprofen by changing micromeritic properties. Seven different formulations of ibuprofen agglomerates such as F-1, F-2, F-3, F-4, F-5, F-6 and F-7 were prepared to convert the needle shaped ibuprofen crystals into agglomerates so that the desired micromeritic properties can be achieved. In this study, agglomerates of ibuprofen were prepared by Quasi emulsion solvent diffusion (QESD) method in association with two surfactants (sodium lauryl sulphateand Tween 80) at three different concentrations for each. The micromeritic properties of the prepared agglomerates were evaluated for bulk density, tapped density, Carr’s index, Hausner’s ratio, angle of repose along with the release behavior of agglomerates. From dissolution study, it was observed that the release of drug was directly proportional to the surfactant concentration. Here, it was also revealed that there was no interaction among ibuprofen and other excipients as evident from DSC and FTIR studies.Bangladesh Pharmaceutical Journal 20(1): 90-98, 2017
