The invention relates to the field of biotechnology and medicine, and specifically to insulin-containing preparations used, in particular, for treating diabetes mellitus. The present preparation comprises a mixture of insulin and a pharmacologically acceptable polymer having a hydrodynamic diameter of more than 4.5+/-0.5 nanometers. As said polymer, at least one polymer having a molecular weight of 20-70 kDa may optimally be used, selected from a group including: dextran, polyethylene glycol and albumin. As regards insulin preparations used in the composition of the preparation, it is possible to use human recombinant insulin and genetically engineered analogues thereof used in the form of commercial preparations. Experiments have shown that using the aforementioned polymers provides insulin preparations with a prolonged effect without the use of chemical or genetic engineering methods to modify insulin molecules. The method is not specific and can thus be applied across a wide range of therapeutic proteins. |
