Abstract: | ABSTRACT The aim of the present research was to investigate the rheological properties of the medicinal syrup for oral administration with glucosamine hydrochloride and levocarnitine. Matherials and methods: Coefficient of the dynamic flow (at shear rates of 3,49 and 10,3 s -1, as well as at shear rates of 27.2 and 149.0 s-1), mechanical stability, the index of destruction and restoration were studied. The rheological (structural-mechanical) properties of the samples were determined using a Rheolab QC rotaryviscometer (AntonPaar, Austria) with coaxial cylinders CC27 / S-SN29766. Therheologicalparameters werestudiedat the temperature 20±0,5 °С. Results: Itisestablishedthatthesyrup hasweaklyexpressedplasticviscousandthixotropicproperties (the hysteresisareaforthesyrupis 1710.19 Pas/s). Such results characterize the system as a reopex. Conclusions:Theresultsofthestudy enables classification of the research objectassystemwith a lowdegreeof fluidity. Such dependenceistypical forsystemsofthe Newtonian typeof flow andcharacterizes thesyrupunder investigation as a weaklystructureddispersesystem. |
