Abstract

Methods are provided for treatment of wounds using a complex antimicrobial sorption composition possessing the necrolytic effect for treating the purulent wounds, the trophic ulcers, the wounds, and the infiltrates with the significant necrotic and exudative components represents the silica sorbent with the immobilized drug. Pyrogenic silica is used as a siliceous sorbent, and serrathiopeptidase as a drug.

Claims (7)

1. A method for treating a wound, comprising the steps:

a) providing an effective amount of a composition of matter comprising a dry powder antimicrobial composition comprising from 90 to 99% by weight a silicious absorbent made of:

globules of hydrated pyrogenic silica and polysilicic acid (SiO 2 *H 2 O); and

the remainder by weight, comprising 1% to 10% serrathiopeptidase immobilized thereon; and

b) applying said composition to the surface of said wound.

2. The method of claim 1 , said pyrogenic silica having an average radius of 4.35 nm.

3. The method of claim 1 , said wound selected from the group consisting of a festering wound, a necrotic wound, an exudative wound, and a wound with inflammatory infiltration.
