Pharmaceutical composition for the preparation of infusion solutions of antimicrobial preparations, its production process (variations)
The proposed compositions and methods for preparation thereof relate to pharmacology, medicine, veterinary science and pharmaceutical industry. The compositions can be used for preparing infusion solutions of antimicrobial (antibacterial and antifungal) preparations increasing therapeutic efficiency thereof. The compositions include nanostructured colloidal silica and are efficient when treating overwhelming sepsis of tested animals, provoked by Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans . The pharmaceutical compositions have a proven and significant clinically important potentiating impact on therapeutic efficiency of the infusion solutions, when treating inflammatory diseases, in comparison with traditional solvents. The methods include—obtaining a mixture of colloidal silica with sodium chloride or with dextrose in a certain weight ratio, which mixture includes a mass fraction of fine-dispersed particles of colloidal silica, having dimensions not exceeding 5 micrometers, and —subjecting the mixture to impacting-abrasive actions, until the mass fraction is increased at least twice.
1. A powder composition for combining with an antimicrobial preparation to produce a formulation for treatment of sepsis in a mammal caused by a pathogen selected from the group consisting of S. aureus, E. coli, P. aeruginosa , and Candida albicans , said powder composition comprising a mechano-chemical activated powder of colloidal silica and sodium chloride, wherein:
(i) the mechano-chemical activated powder is activated by intensive mechanical impact and abrasive action;
(ii) the sodium chloride and colloidal silica constitute a weight ratio of 9:1 to 9:5; and
(iii) the colloidal silica consists of silica nanoparticles having an average diameter of from 7 nm to 40 nm joined into microparticles having a size of less than 100 μm.
