example 1

[0031] Example 1. Preparation of solid composition. NaCl: colloidal silicon dioxide.

[0032] Blends of sodium chloride and colloidal silica in weight ratios of 4.5:1, 4.5:2, 4.5:5, 9:1, 9:2, and 9:5 were processed in a rotary drum mill1 , 2 or 4 hours.

[0033] The particle content of suspensions of initial colloidal silica particles and their composition with NaCl in different variants in water was analyzed on a Microsizer-201а particle size laser analyzer manufactured by the Russian company «VA Instalt». Place 1g to 5g of the powder under study into the sample preparation module (liquid volume 150sm 3 ) in an amount sufficient to transmit 70% to 75% of the light through the test tube. After 1 or 2 minutes, the measurement is taken while the suspension is processed to break up clumps. Data processing is performed according to a calculation program embedded in the analyzer. The results are presented in the form of a histogram of weight distribution versus particle size. ...

example 2

[0040] Example 2. Preparation of solid composition

[0041] Dextrose: Colloidal silicon dioxide. Blends of dextrose and colloidal silica in weight ratios of 20:1, 20:2, 20:5, 50:1, 50:2, and 50:5 were processed in a rotary drum mill1 , 2 or 4 hours.

[0042] Following the method described in Example 1, the particle content of the suspension of colloidal silica in water and the adsorption rate of antibiotics were measured. The data obtained are shown in Table 2. From these data, it can be seen that the method for preparing the provided composition also increases the proportion of the colloidal silica fine powder fraction (particle size ≤ 5 μm) by at least 2 times and the binding of colloidal silica particles to the molecules of the antimicrobial preparation reached at least 40%.

example 3

[0046] Example 3. Determination of the therapeutic efficacy of a solution (for intravenous injection) based on an antibacterial preparation prepared using a pharmaceutical composition.

[0047] A study has been conducted against β-lactam antibiotics (amoxicillin + clavulanic acid, cefotaxime, ceftriaxone, cefoperazone + sulbactam, ceftazidime, cefepime, aztreonam, meropenem), Research on macrolides (azithromycin), aminoglycosides (amikacin sulfate), glycopeptides (vancomycin), antifungals (voriconazole), and fosfomycin.

[0048] In order to determine the therapeutic efficacy of antimicrobial agents, an experimental model of sepsis was first established, and according to [19, 20], the obtained results (χ 2 ) statistical processing method.

[0049] microorganism : Staphylococcus aureus (ATCC No. 25923F-49), Escherichia coli (ATCC No. 25922F-50), Pseudomonas aeruginosa (ATCC No. 27853F-51), Candida albicans (ATCC No. 24433).

Abstract

The present invention relates to pharmacology, medicine, veterinary medicine and the pharmaceutical industry, that is, to pharmaceutical compositions for the preparation of infusion solutions of antibacterial preparations, which are A pharmaceutical composition enhances the therapeutic efficacy of an antibacterial drug; and also relates to a method of preparing an initial compounded pharmaceutical composition. The provided pharmaceutical compositions containing finely divided nanostructured colloidal silica powders for the preparation of injections of all tested antibacterial formulations were tested in the treatment of test animals with Staphylococcus aureus (Staphylococcus aureus), Escherichia coli (Escherichia coli), Pseudomonas aeruginosa (Pseudomonas aeruginosa) and Candida albicans (Candida albicans) caused by refractory sepsis definitely increased its therapeutic efficacy. Compared with traditional solvents (prototype of the present invention), the provided pharmaceutical composition (NaCl: colloidal silicon dioxide and dextrose: colloidal bismuth) for the preparation of antibacterial preparations and antifungal preparations for intravenous infusion Silicon oxide) is clinically of considerable importance in enhancing the therapeutic potential of said antibacterial and antifungal agents for the treatment of malignant infectious and inflammatory diseases.

Description

technical field [0001] The present invention relates to pharmaceutical preparations suitable for the preparation of solutions of injectable preparations of antibacterial drugs and their compounding techniques, which can be used in medicine and veterinary medicine for the treatment of infectious and inflammatory diseases of different etiologies, and in the pharmaceutical industry for the preparation of raw materials drug and final dosage form.
