Objective: The aim of the present study was to select excipients in an oral solid dosage form with a dry extract of round-leaved wintergreen (Pyrola rotundifolia L.) by using asymmetric, rotatable composite plan of the second-order (uniform plan No. 17). Methods: The tablets were prepared by using a direct compression method. The most important pharmaceutical factors selected were considered in more details at developing the optimal composition and technology of the studied tablets of the round-leaved wintergreen extract. Each one was studied at five levels using asymmetric, rotatable composite plan of the second order. Results: Increasing amounts of PROSOLV® EASYtab SP and croscarmellose sodium in the powder mass, its flowability decreases, and increasing amounts of Tablettose® 80 improves flowability. Increasing the amount of Tablettose® 80 in the tablets composition leads to improved uniformity. The strength of the tablets increased with increasing amounts of Neusilin® US 2 at different combinations of levels of the other three factors. When studying the effect of the amounts of croscarmellose sodium on the disintegration of tablets, it was found that the best disintegration values were obtained in the study of croscarmellose sodium at the upper level. Conclusion: Oral solid dosage form with dry extract of round-leaved wintergreen was successfully prepared by the direct compression method. The optimal composition of tablets was determined by the regression analysis.

Pharmaco-technological and physico-chemical properties of the samples were studied according to conventional methods of the State Pharmacopoeia of Ukraine. Results and discussion. According to the results of the crystallographic analysis, the ability to the moisture absorption, resistance to crushing, disintegration time, fluidity indicators, angle of repose and bulk volume the effect of modern excipients on physicochemical and pharmaco-technological properties of the dry extract of ginger has been studied. Conclusions. According to the results of microscopic analysis, it has been found, that the rational fillers are GalenIQ 721, Prosolv HD 90, Prosolv SMCC 50, Vivapur 102 and Vivapur 112, as they provide a uniform system and the necessary resistance to destruction. The study of the kinetics of the moisture absorption has shown that addition of the fillers significantly reduces the increase in moisture compared to the dry extract. The mixture with GalenIQ 721 has the lowest parameters of moisture absorption at a relative air humidity of 45 %, 75 % and 100 %. In accordance with the results of the pharmaco-technological studies, it has been found that addition of GalenIQ 721 leads to improved flowability, disintegration, settling qualities; it indicates the feasibility of its inclusion into the composition of the solid dosage form.

Objective: The main objective of this study is comparative study of natural and synthetic superdisintegrants in orodispersible Metformin tablet by using direct compression method and wet granulation method. Method: Orodispersible Metformin tablet were prepared by wet granulation method and direct compression method by using different synthetic and natural superdisintegrants. Orodispersible tablets (ODTs) have received more interest in the pharmaceutical industry for their easy to use and self medication. ODTs overcome the problem of dysphagia (difficulty in swallowing) in the all group age of patients and advantage particularly for the paediatric and geriatric patients. Metformin hydrochloride (Hcl) is an orally administered antihyperglycemic agent, used in the management of non-insulin dependent (type-2) diabetes mellitus. Metformin orodispersible tablet is prepared by using two methods i.e. direct compression method and wet granulation method. Both methods are applied to prepare Orodispersible Metformin tablet. Orodispersible tablet of Metformin was prepared by using superdisintegrants from both natural and synthetic origin. In natural superdisintegrants we used the mucilage of Fenugreek and Lepidium sativum. In synthetic superdisintegrants we used crospovidone and sodium starch glycolate. Conclusion: In direct compression and wet granulation method final blend and granules were evaluated the flow properties like bulk density, tapped density, compressibility index, hausner’s ratio and angle of repose. The values of precompression parameter evaluated were found to be within the prescribed limit and indicated good flow properties. The data obtained from the post compression methods was studied. Other parameters such as wetting time, water absorption ratio were also evaluated. The formulation (F5) containing 10% crospovidone prepared by wet granulation method was found the optimize formulation.

The aim. The aim of the research was to study the effect of different groups of excipients on the pharmaco-technological propertiesof the powder mass for tabletting in the development of the composition of the tablets with dry extract of Sanguisorba officinalis for complex therapy of the gastrointestinal tract diseases. Materials and methods. Objects of study - dry extract Sanguisorba officinalis, 25 excipients used in the production of tablets by the method of direct compression, grouped into five groups of factors (fillers based on sugars and microcrystalline cellulose, disintegrants, glidants and lubricants), samples of powder masses. Studies on the determination of pharmaco-technological properties (fluidity, bulk density, bulk density after shrinkage, degree of compressibility, Hausner ratio, and angle of repose) of the obtained powder masses were carried out according to the methods of the State Pharmacopoeia of Ukraine, Second edition. The method of mathematical planning of the experiment was used in the work, the obtained results were subjected to variance analysis, and the ranked series of advantages were placed, in which the excipients were placed in the sequence of their influence on the studied pharmaco-tecnological parameters. Results and discussion. The influence of excipients (factors) on the pharmaco-technological properties (responses) of the powdered tablet masses with the construction of ranked benefits was studied using a five-factor experiment, a hyper-Graeco-Latin square. The results of the analysis of variance showed that glidants have the greatest influence on the fluidity, the bulk density and the bulk density after shrinkage. Neusilin US 2 significantly affects the fluidity of the powder masses and Hausner ratio, the talc having the greatest effect on the bulk density and the bulk density after shrinkage of the powder masses. The representative of the disintegrants group – Sodium starch glycolate most influences the compressibility index, the sugar-based filler – Pearlitol 500 DC – on the angle of repose. Conclusions. The effect of 25 excipients on the pharmaco-technological characteristics of the powdered tablet masses with dry extract of Sanguisorba officinalis was studied. It was found that among the sugars-based fillers equally good results were shown in the powder masses with Compri sugar, Tablettose 80 and Pearlitol 500 DC; among the microcrystalline cellulose based fillers is Prosolv 90; among glidants – Neusilin US 2; no comparison was made of the disintegrants and lubricant excipients from the studied list of leader substances. The results of the studies indicate the possibility of obtaining tablets by the direct compression method, and further study of their pharmaco-technological characteristics will allow to establish the optimal composition of excipients.
