    摘要: The invention relates to novel materials based on biodegradable homopolyamino acids and which can be used for the vectorization of (an) active ingredient(s) (AI). The invention also relates to novel pharmaceutical, cosmetic, dietetic or phytosanitary compositions based on said homopolyamino acids. The aim of the invention is to produce a novel polymer raw material which can be used for the vectorization of AI and which meets all specifications in an optimum manner: biocompatibility, biodegradability, the ability to become easily associated with a large number of active ingredients or to solubilize them and to release said ingredients in vivo. According to the present invention, which primarily relates to linear homopolyamino acids having aspartic or glutamic units and whose extremities include hydrophobic groups having 8-30 carbon atoms. Said homopolymers are amphiphilic and anionic and can easily be transformed at low cost into particles for the vectorization of active ingredients. Said particles can form stable aqueous colloidal suspensions.

    摘要: The invention relates to oral pharmaceutical compositions for the prevention and/or the treatment of viral diseases. This invention also addresses methods of prevention and/or treatment of these viral diseases, using these oral compositions. One of the main problems considered in the present invention is to enhance the efficiency of anti-viral treatments, especially against Hepatitis C virus by means of ribavirin, for example in combination with interferon. The oral ribavirin antiviral composition according to the invention increases the bio-absorption time of ribavirin, and thus improves the treatment of patients. Said composition comprises at least one modified release form of ribavirin, the bio-absorption time BAT of which is greater than the bio-absorption time BAT* of a reference* immediate release form of ribavirin administered at the same dose; BAT being preferably comprised between 2 and 15 h and more preferably between 4 and 12 h. Said composition is a reservoir type form or a matrix type form. Said composition is a gastric retentive system or a multiparticulate form.
