    Opis:
    W artykule przedstawiono wstępne wyniki porównawczych badań wytrzymałościowych i cech antykorozyjnych oryginalnych części nadwozi samochodowych i ich zamienników. Wyniki tych badań pozwalają wnioskować o przydatności niektórych zamienników, a równocześnie mogą być wstępem do wypracowania kryteriów jakościowych dopuszczenia do użytkowania zamienników części nadwozi.
    Preliminary results of comparative strength tests and anti-corrosion characteristics of original car body parts and replacements of these parts are presented. The results allow concluding about the suitability of some substitutes, and at the same time may be a prelude to the development of quality criteria for obtaining a certificate for release to service of replacements for body parts.

    The aim of the study was to evaluate the effect of Carbopol 934 P and PVP K 90 on the rheological properties of chitosan gels. Hydrogels were prepared with hydrocortisone containing chitosan, Carbopl 934P, PVP, propylene glycol-1,2 or polyethyleneglycol 400 and glycerol. Addition of polymers had positive influence on the dispersion of hydrogels. The studied gels have thixotropic properties, their viscosity increases with the increase of the concentration of polymers. Increase of the content of polyvinylpyrrolidone K 90 and Carbopol 934 P increases the consistence, gels are more firm and cohesive. Gels with 5 % chitosane, 15% polyvinylpyrrolidone K 90 and Carbopol 934 P in the presence of additives have prolonged half release period of hydrocortisone.

    The aim of the study was to evaluate the effect of changing the concentrations of chitosan on the rheological properties of the obtained formulation. Hydrogels were prepared with 1% hydrocortisone containing 4% sodium carboxymethylcellulose with the addition of chitosan, propylene glycol-1,2 or polyethylene glycol 400 and glycerol or paraffin. The concentration of chitosan and excipients affects the rheological properties of gels and the pharmaceutical availability of hydrocortisone. Increasing the concentration of chitosan have influence on increasing the viscosity, hardness, and cohesiveness of the tested gels.

    Opis:
    Combinations of polymers and biopolymers of biologically active compounds in the last period have been the subject of intensive research. The active substance linked to a polymer often has a modified function and sometimes no action. On the other hand, the use of unsuitable polymers may result in a type of mismatch of drug-polymer. The aim of the study was to examine whether the active substance ketoconazole causes incompatibility with dietary supplements containing chitosan. Antifungal drug adsorption phenomenon was investigated by the static method in the concentration range of the single dose using a pharmaceutical model of the gastrointestinal tract. The test results show that the antifungal agent is adsorbed onto the chitosan in the pH ranges used, and the binding ability of the chitosan depends on the variety, or indirectly from the reaction environment. It was observed that the average sorption, depending on the variety of chitosan, was located in the limit from 94% to 100%. The increase of the size of the adsorption of anti-inflammatory drugs on the polymer with increasing pH from 7.6 to 8.0 can be explained by the swelling properties of chitosan, which grow with increasing pH of the environment in the direction of alkaline pH. Thus, the specific surface area and polymer sorption capacity is increased. Based on the above considerations, it can be concluded that, between the test drug and the polymer, there is antagonistic interaction involving the adsorption of the drug of this group on a polymer which is chitosan.

    The aim of the study was to investigate the effect of chitosan on the dissolution of fenofibrate incorporated into this polymer carrier. The study investigated fenofibrate in physical mixtures at the drug to polymer ratio of 1:9, 3:7, and 5:5. The solubility investigation was performed by means of a dynamic method in a dissolution apparatus; mean amount of dissolved fenofibrate and the drug to polymer quantitative ratio in which the solid dispersion possessed the most beneficial properties improving the drug solubility were calculated. The study revealed a multi-fold increase (from 13 to 70 times) in fenofibrate solubility in the presence of chitosan, which increased with duration of the study and with increasing percentage of the polymer in formulations. The dissolution rates of fenofibrate in the presence of chitosan at the weight ratio 1:9 increased with the increment of the molecular weight of the chitosan. The obtained results may help develop new technologies for fenofibrate preparations with chitosan, with better solubility characteristics, and thus increased bioavailability of the drug.

The solubility investigation was performed by means of a dynamic method in a dissolution apparatus; the mean amount of dissolved ketoprofen and the drug to polymer quantitative ratio in which the solid dispersion possessed the most beneficial properties improving the drug solubility were calculated. The study revealed a multifold increase (33 times) in ketoprofen solubility in the presence of chitosan, which increased with duration of the study and with increasing percentage of the polymer in formulations. The dissolution rates of ketoprofen in the presence of chitosan at the weight ratio 1:9 increased with the decrease of the molecular weight of the chitosan. The results obtained may help to develop new technologies for ketoprofen preparations with chitosan, with better solubility characteristics, and thus increased bioavailability of the drug.

    Opis:
    In clinical practice for the treatment of obesity, several natural macromolecular compounds are used, whose operation is based on supporting weight loss. During the use of dietary supplements containing chitosan, disease sometimes occurs and treatment for this often comprises different therapeutic agents and antibiotics. The aim of our study was to determine the binding capacity of simvastatin to chitosan, which is found in dietary supplements promoting weight loss, depending on variable physicochemical factors in the gastrointestinal tract model. The phenomenon of adsorption of simvastatin was investigated by a static and dynamic pharmaceutical model (according to the Modified method of Polish Pharmacopoeia IX) simulating the conditions in vitro. The amount of bound drug is used to calculate the average percentage of the adsorbed dose. The obtained results showed that simvastatin is adsorbed by chitosan in the used pH ranges, and the binding capacity is dependent on the environmental pH, viscosity, the concentration of the drug, the type of chitosan and additional substances present in the gastrointestinal tract. The average adsorption of simvastatin in the system of chitosan-nutrients, depending on the pH of the medium, was in the range of 27 to 95%. The highest amount of adsorption was noted above pH 7 (chitosan precipitated polymer forming the emulsion-gel system), when the bioavailability of dietary supplement using chitosan was almost zero.

    The aim of the present study was to increase the solubility of ibuprofen. Among the methods to increase the solubility selected solid dispersions of the drug with the polymer. Chitosan was used as the polymer. Solid dispersion obtained. Ibuprofen was incorporated into the chitosan type 652 with molar masse chitosan Mη = 429 kDa. Solid dispersions were prepared by using different ratios of ibuprofen and chitosan (1:9. 3:7 and 5:5). Formulations were tested dissolution rate of the ibuprofen. The highest dissolution of ibuprofen, amounting to 12.59%, was observed after 60 minutes from solid dispersion prepared by the evaporation method and 12.18% from physical mixtures with drug-polymer weight ratio 1:9 in the presence chitosan. The solubility of the drug improved more than 60-fold. XRPD analysis indicates the presence of the ibuprofen in amorphous form in the solid dispersion obtained by the modified solvent evaporation.
