| abstract |
FIELD: chemical-pharmaceutical industry, pharmacy. n SUBSTANCE: invention relates to a new pharmaceutical preparation comprising active substance and chitosan derivative that present in nanosol in an isoionic state. Pharmaceutical preparation is prepared by the following manner: the chitosan derivative is taken to provide isoionic state at the definite level of pH value or equilibrating charges of active substance and a carrier in the preparation. An aqueous sol is prepared from chitosan derivative that contains an active substance. The pH level is regulated to provide an isoionic state at possible precipitation of colloidal particles or nanoparticles of active substance, and prepared sol is dried. Pharmaceutical preparation elicits the enhanced bioavailability, releases active substance rapidly and stable in storage. n EFFECT: improved and valuable properties of pharmaceutical preparation. n 8 cl |
