Zusammenfassung: | A stable pharmaceutical composition containing, as the active substance, tenofovir disoproxil fumarate, or a combination of tenofovir disoproxil fumarate with another active substance, which further contains a disintegrant selected from the group including crospovidone, maize starch, and hydroxypropylcellulose. Additionally, a stable pharmaceutical composition containing, as the active substance, tenofovir disoproxil fumarate, or a combination of tenofovir disoproxil fumarate with another active substance, which further contains sodium salt of croscarmellose and an acid selected from the group including fumaric, citric, malic, maleic, L-tartaric, and malonic acids. Using of the dispersant or the combination of sodium salt of croscarmellose and acid prevents the conversion of tenofovir disoproxil fumarate to tenofovir disoproxil hemifumarate (TDF to TDHF).
L'invention concerne une composition pharmaceutique stable contenant, comme substance active, du fumarate de disoproxil de tenofovir ou une combinaison de fumarate de disoproxil de tenofovir et d'une autre substance active, qui contient en outre un délitant choisi parmi le groupe constitué de crospovidone, d'amidon de maïs et d'hydroxypropylcellulose. De plus, une composition pharmaceutique stable contenant, comme substance active, du fumarate de disoproxil de tenofovir ou une combinaison de fumarate de disoproxil de tenofovir et d'une autre substance active, contient en outre un sel de sodium de croscarmellose et un acide choisi parmi le groupe constitué d'acides fumarique, citrique, malique, maléique, L-tartrique et malonique. L'utilisation du délitant ou de la combinaison de sel de sodium de croscarmellose et d'acide empêche la conversion du fumarate de disoproxil de tenofovir en hémifumarate de disoproxil de tenofovir (TDF en TDHF). |
