Abstract: Provided are pharmaceutical compositions comprising an anion exchanger and a calcium salt; methods for inducing hemostasis at a site of bleeding by applying to the site of bleeding an effective amount of the compositions; and methods of preparation of the compositions.

Abstract: An expandable biodegradable hemostatic matrix comprised of oxidized cellulose, and having a density ranging from about 0.8 to about 1.2 gr/cm3 is disclosed herein. The matrix may be expandable to at least 3 times its original volume within 4 sec upon contact with an aqueous solution room temperature. Further disclosed are methods for making the hemostatic matrix as well as method of treating a wound.

Abstract: The present invention provides compositions comprised of oxidized cellulose (OC) and glycerol, with the ratio of glycerol to OC being at least about 0.5:1 w/w glycerol:OC and/or with the viscosity of the composition being at least 10% higher than that of the glycerol and lower than about 2.6×109 cP, with the total water content being less than about 8% w/w. Further provided is adhesion prevention powder comprised of OC having a carboxyl content of equal to below 18% characterized by high adhesion prevention potency. Uses of the compositions as hemostats or as adhesion prevention material, and methods for the preparation thereof are further provided herein.
