RESUMO
The ciclopirox olamine (CPO) has a broad antimicrobial profile including dermatophytes, yeasts and is used in various pharmaceutical forms. The aim of this study is to evaluate the quality of the CPO gels according to biopharmaceutial tests in vitro and antifungal activity assay. Hydroxypropyl cellulose, chitosan and poloxamer 407 were selected as agents gelificants. The effects of gelling agent properties and concentration on the consistency and flow characteristics have been studied by rheometer. CPO release rates from gel were measured with Franz type diffusion cells. The antifungal activity of gels was tested using agar well diffusion technique. The results of the experimental study have shown that the rheological properties of the medications depend on the selected gelling agent and the amount of it. The higher amounts of CPO were released from the poloxamer 407 gels. Though all tested CPO gels showed great inhibition of Microsporn canis.
