A comparative analysis of the specific pharmacological activity and wound-healing properties of zinc oxide nanoparticles (ZnO-NPs) was carried out. It has been shown that ZnO-NP forms reduce the severity of formalin paw edema in mice and the exudative reaction in "felt" granuloma in rats. Notably, the effectiveness of the ointment form exceeded the effectiveness of the gel form. The ability of ointment and gel based on ZnO-NPs has been shown to significantly reduce the recovery time of hemorrhagic soft tissue injuries in rats and, unlike medicinal forms of heparin, to increase the blood clotting time of rabbits by 1.25 times and 1.19 times, respectively. Thus, ointment and gel containing ZnO-NPs are potential medicines with anti-inflammatory, anticoagulant properties and the property of shortening the recovery time of hemorrhagic soft tissue injuries. It is concluded that the therapeutic effect of samples containing ZnO-NPs, due to the ability of these nanoparticles to penetrate the skin epithelium, providing regenerating and fibrinolytic activity, blocking the activity of inflammatory mediators and providing, including the systemic effect on blood clotting.
