5 PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

ATC Code: D0 8A

Antiseptics and Disinfectants

Hydrogen peroxide is a well-known antiseptic agent, and is effective against a majority of pathogenic micro-organisms.

In-vitro pharmacology studies have shown that hydrogen peroxide has both activity against a wide variety of micro-organisms, and is a potent antibacterial agent with effect against Gram-positive as well as Gram-negative bacteria.

In-vitro studies have shown that the bactericidal activity of Crystacide cream

1% is equal in effect compared with a 1% aqueous solution of hydrogen peroxide, and the duration of action is longer for the cream.

There are no known pathogenic bacteria or fungi that develop resistance to hydrogen peroxide.

5.2 Pharmacokinetic properties

Reports on the rate of absorption, distribution and excretion of hydrogen peroxide after oral administration are sparse. In the absence of stabilising agent, hydrogen peroxide gradually decomposes to oxygen and water. The decomposition is rapid in the presence of the endogenous enzyme catalase or peroxidase.

5.3 Preclinical safety data

There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
