BIOERODIBLE COMPOSITION FOR THE ADMINISTRATION OF A BIOACTIVE AGENT, KIT FOR FORMATION OF A BIOERODIBLE COMPOSITION, METHODS OF PRODUCTION OF A BIOERODIBLE COMPOSITION FOR THE ADMINISTRATION OF A BIOACTIVE ADDITIONAL ADMINISTRATOR IMPLANTABLE DOCTOR, AND METHOD OF ADMINISTRATION OF A BIOACTIVE AGENT TO A BODY SITE NEEDING IT. A bioerodible composition for providing a bioactive agent is the reaction product of a reaction mixture including an oxidized dextrate solution, and a solid mixture containing a dihydrazide, a bioactive agent, and optionally a ph adjusting agent. in an amount sufficient to produce a reaction mixture ph of 6 or less. The composition may include a release agent for the controlled release of the bioactive agent from the composition. The bioactive agent may therefore be delivered to the body site in need thereof by providing a first aliquot portion of a reaction mixture by providing a first aliquot portion of a reaction mixture composed of an oxidized dextrate solution. , and a second aliquot portion of a reaction mixture composed of a mixture of solids composed of a dihydrazide, a bioactive agent, and a solid acid which is present in a quantity sufficient to produce a reaction mixture ph of 6 or memos, mixing the first and second aliquot portions to form the reaction mixture thereof, and then installing the reaction mixture at the body site, allowing a bioerodible drug delivery composition to be formed in situ thereof. . The present invention may be presented in the form of a kit consisting of a double syringe containing respectively the first and second aliquots of the reaction mixture so that they may be mixed immediately prior to use.COMPOSIçãO BIOERODìVEL PARA A ADMINISTRAçãO DE UM AGENTE BIOATIVO, KIT PARA A FORMAçãO DE UMA COMPOSIçãO BIOERODìVEL, MéTODOS DE PRODUçãO DE UMA COMPOSIçãO BIOERODìVEL SOLIDIFICADA PARA A ADMINISTRAçãO DE UM AGENTE BIOATIVO E DE FORMAçãO DE UM FILME BIOERODìVEL PARA A ADMINISTRAçãO DE UM AGENTE BIOATIVO, DISPOSITIV
