ABSTRACT:
A long acting antimicrobial and especially antibacterial composition (a) free elemental iodine (b) a polymeric linear polymer formed from the recurrence of the 2-pyrrolidone monomer ##STR1## HAVING A MOLECULAR WEIGHT OF 1,000 TO 500,000 AND PREFERABLY WHEREIN N IS SUFFICIENTLY LARGE TO FORM A POLYMER HAVING AN INHERENT VISCOSITY OF AT LEAST 2.0 AND PREFERABLY FROM 3.0 TO 5.0 DECILITERS PER GRAM. AND (C) A HIGH MOLECULAR WEIGHT ISOTONIC ACIDIC MATERIAL PREFERABLY A POLYCARBOXYLATED ACID POLYMER SUCH AS POLYACRYLIC ACID OR A POLYCARBOXYLATED VINYL RESIN HAVING A MOLECULAR WEIGHT OF AT LEAST 10,000 AND PREFERABLY BETWEEN 250,000 AND 300,000 GRAM MOLECULAR WEIGHT UNITS. Ointments, dressings and sutures all are made from this polymer complex.
