Patent

CA 2413990

A package comprising components which, upon being mixed, are capable of forming a pharmaceutical composition that is effective in treating acne, the composition tending to degrade prematurely, one of the components comprising an oxidizing agent and another of the components comprising an antibiotic which is effective against acne-associated bacterial species, the components separated one from the other in the package, one component having a viscosity within about 50 % of the viscosity of the other component. In addition, a package comprising: (A) components which, upon being mixed, are capable of forming a pharmaceutical composition that is effective in treating acne, one of the components comprising a benzoyl peroxide gel and another of the components comprising a gel of erythromycin and hydroxypropylcellulose; and (B) containers for holding the components in the package separated one from the other; the components having viscosities such that, upon the application of a uniform forces to the components, substantially equal volumes of the components are capable of being dispensed simultaneously from the containers.

L'invention porte sur un conditionnement comprenant des composants qui, lorsqu'on le mélange, sont capables de former une composition pharmaceutique efficace dans le traitement de l'acné, cette composition ayant tendance à se dégrader prématurément. L'un des composants comprend un agent d'oxydation et l'autre un antibiotique efficace contre les espèces bactériennes associées à l'acné. Ces deux composants sont séparés dans le conditionnement, l'un ayant une viscosité représentant environ 50 % de la viscosité de l'autre. Ce conditionnement comprend de plus : (A) des composants qui, lorsqu'on les mélange, peuvent former une composition pharmaceutique efficace dans le traitement de l'acné, l'un des composants comprenant un gel de peroxyde de benzoyle et l'autre un gel d'érythromycine et d'hydroxypropylcellulose ; et (B) des réceptacles accueillant les composants et séparés l'un de l'autre dans le conditionnement. Ces composants ont des viscosités telles que, lors de l'application d'une force uniforme sur les composants, des volumes pratiquement égaux des composants peuvent être distribués simultanément depuis les réceptacles. La composition de traitement de l'acné comprend également : (A) un peroxyde de benzoyle ; (b) érythromycine ; et (c) hydroxypropylcellulose.
