Summary:
The present paper investigates drugs and polymers intended for the impregnation of textile carriers
intended for use as wound covers. Their suitability was evaluated on the basis of the evaluation of
the antimicrobial efficacy of a combination of trimetoprim and sulfadimidine with the local anaes-
thetics carbizocaine and lidocaine, and the immunomodulating substance fungal glucan. A greater
inhibitory effect on the growth of microorganisms was shown by a combination of antimicrobial
substances with carbizocaine. In the study of liberation of chlorohexidine from hydrophilic macro-
molecular dispersions its bond to glucan was confirmed. Dispersions of Natrosol proved to be more
advantageous; chlorohexidine as well as local anaesthetics were released from them more rapidly
than from methylcellulose gels. The dispersions under study are of a non-Newton character with
pseudoplastic flow, glucan-containing gels are thixotropic.
Key words:
textile wound covers – antimicrobial substances – local anaesthetics – glucan –
liberation of drugs
