The invention refers to a novel pharmaceutical composition having especially antimycotic activity and comprising the zinc complex of 5-chloro-7-iodo-8-hydroxyquinoline of formula (I) < IMAGE > (I) and one or more pharmaceutically acceptable carriers. The pharmaceutical composition of the invention can be used for the effective treatment of mycotic infections on the skin surface, mucous membranes or nails. The complex of formula (I) is prepared by reacting a solution of an alkali metal salt of 5-chloro-7-iodo-8-hydroxyquinoline with a solution containing an excess of an inorganic or organic zinc salt or a zinc complex having a lower stability constant than that of the complex of formula (I) and separating the product precipitated. EL COMPLEJO DE FORMULA (I) SE PREPARA HACIENDO REACCIONAR UNA SOLUCION DE UNA SAL METALICA ALCALINA DE 5-CLORO-7-YODO-8-HIDROXI-QUINOLINA CON UNA SOLUCION QUE CONTENGA UN EXCESO DE UNA SAL INORGANICA U ORGANICA DE CINC O UN COMPLEJO DE CINC DOTADO DE UNA CONSTANTE DE ESTABILIDAD INFERIOR A LA DEL COMPLEJO DE FORMULA (I), Y SEPARANDO EL PRODUCTO PRECIPITADO.LOS PRODUCTOS OBTENIDOS SON APLICABLES AL TRATAMIENTO EFECTIVO DE INFECCIONES MICOTICAS EN LA SUPERFICIE DE LA PIEL, MEMBRANAS, MUCOSAS O UÑAS.
