Mechanism of Action of Preservative
Sodium perborate was one of the first
oxidative preservatives to be developed. It destroys numerous types of bacteria
and can destroy Aspergillus niger, a fungus that is difficult to kill.
Sodium perborate is a precursor of H2O2. When sodium perborate
combines
with water it produces hydrogen
peroxide, an effective antimicrobial agent. Once sodium perborate is
instilled in the eye, it is decomposed into water and oxygen by catalase
and other enzymes present in the conjunctival sac in maximum 60 sec.
