TECHNOLOGICAL BASIS FOR THE CREATION OF IMPLANTS WITH A PHARMACEUTICAL COMPOSITION OF CIPROFLOXACIN AND THEIR ANTIMICROBIAL ACTIVITY IN EXPERIMENTS IN VITRO
Аннотация:The article is devoted to the investigation of the possibility of immobilized on the surface of the titanium implantable devices (model plates, “U-shaped” brackets) antimicrobial substances. Material and methods . The object of research were modeling titanium plates and titanium “U-shaped” brackets for implantation. Ciprofloxacin, hydroxypropylmethylcellulose and methylcellulose has been proposed as materials for the creation of antimicrobial pharmaceutical composition to immobilization. The antimicrobial properties of titanium implantable “U-shaped” brackets with ciprofloxacin was evaluated for potential antimicrobial activity against medically important bacterial (S. aureus, P. aeruginosa, E. coli, E. faecalis and S. pyogenes) using method of diffusion in agar. Results . The results showed the possibility of putting and holding а ciprofloxacin in grooves on the modified surface of titanium implants. In the course of the study was developed a pharmaceutical composition, comprising ciprofloxacin and hydroxypropylmethylcellulose. The results showed high antimicrobial activity of pharmaceutical composition with ciprofloxacin against the test organisms (S. aureus, P. aeruginosa, E. coli, E. faecalis and S. pyogenes).
