Development of a biocompatible, biodeshipple polymer for medicine and agriculture, able to long-term extract of bioactive substances

A team of authors developed a technology for producing biocompatible biodegradable polymer films based on high-molecular polylactide with the properties necessary for medical and agricultural use. A technology has been developed for the inclusion of active substances (gentamicin sulfate, lincomycin hydrochloride, cefotaxime) into films of high-molecular polylactide. The rate of release of active substances from polylactide can vary with time as a decaying exponent, as well as a function close to linear. The process of release of active substances is significantly affected by the pH of the surrounding film of the solution. It was found that the dynamics of release of active substances from biocompatible biodegradable polymer films created on the basis of high-molecular polylactide depends on the properties of the substance immobilized in the film, the technology of the film and the conditions under which the extraction is carried out. The technical parameters of biocompatible biodegradable polymer films based on high-molecular polylactide are quite suitable for the manufacture of coatings of stents and prostheses with prolonged and controlled release of drugs into the surrounding tissues, as well as for use in agriculture to increase the safety of the harvest.
