CRYOPROTECTIVE OINTMENT Russian patent published in 2005 - IPC

FIELD: pharmaceutics.

SUBSTANCE: the present innovation deals with cryoprotective ointment containing recombinant interferon-α₂. The suggested cryoprotective ointment contains recombinant interferon-α₂, glycerol, polyethylene glycol 300-6000, polyglucin, buffered 0.02%-Trilon B solution at pH of 5.5-7.0 and ointment foundation at a certain content of components per 1.0 g ointment. Additionally, cryoprotective ointment could contain glycine 3,7-bis(dimethylamino)phenothiazonium chloride, dry immunoglobulin preparation or dry immunoglobulin preparation for enteral application. Ointment foundation of cryoprotective ointment could contain water-free lanolin, Vaseline and Vaseline oil, at the following ratio of components: 2.5;3.5:1 - 6.5:0.5:1. The innovation provides maximal safety of recombinant interferon-α₂ activity in cryoprotective ointment at multiple alteration of positive and negative environmental temperature and at keeping cryoprotective ointment under these conditions.

EFFECT: higher efficiency of application.
