Kinase experiment: | The bactericidal activities of OCT and CHG against Staphylococcus aureus are measured by exposing cultures to several different concentrations of each compound for various lengths of time. OCT is diluted from the 5 mM stock solution and tested in phosphate buffer at levels ranging from 0.5 to 5.0 FsM. The test is begun by adding the bacterial culture to the test solution containing OCT or CHG; samples are taken at 5, 15, 30, and 60 min afterward. The inoculum size is approximately 106 CFU/mL[1]. |
Animal experiment: | Monkeys: Four solutions of OCT are prepared by dissolving OCT in distilled water to final concentrations (wt/wt) of 0.2, 0.4, 0.8 and 1.6%, equivalent to 3.2, 6.4, 12.8 and 25.6 mM, respectively. Skin-degerming activities of aqueous and formulated octenidine and formulated chlorhexidine are compared in single and multiple applications of these agents to the hand and foot surfaces of monkeys by using a glove-juice extraction procedure to measure the skin microflora[1]. |

Octenidine is an antimicrobial agent.1 It is active against a variety of bacteria, including methicillin-sensitive and -resistant S. aureus, vancomycin-resistant Enterococcus, E. faecalis, and S. pneumoniae (MICs = 1-32 mg/L), and the fungus C. albicans (MIC = 1 mg/L). Octenidine (2 mM) reduces methicillin- or vancomycin-resistant S. aureus biofilm formation.2 Topical application of octenidine (1%) reduces dental plaque accumulation in cynomolgus monkeys fed a high-sucrose diet.3

Octenidine dihydrochloride: chemical characteristics and antimicrobial properties
J Wound Care2016 Mar;25(3 Suppl):S3-6.PMID:26949863DOI:10.12968/jowc.2016.25.Sup3.S3.
The empiric use of antibiotics is being restricted due to the spread of antimicrobial resistance. However, topical antiseptics are less likely to induce resistance, owing to their unspecific mode of action and the high concentrations in which they can be used. One such antiseptic, Octenidine dihydrochloride (OCT), can be used either prophylactically or therapeutically on the skin, mucosa and wounds. Evidence to support its use comes from in-vitro, animal and clinical studies on its safety, tolerability and efficacy. This article summarises the physical, chemical and antimicrobial properties of OCT in the context of wound care.
Antimicrobial and antiseptic strategies in wound management
Int Wound J2013 Dec;10 Suppl 1(Suppl 1):9-14.PMID:24251838DOI:10.1111/iwj.12175.
Wounds, especially chronic wounds, represent a global problem costing millions of dollars per year in developed countries and are characterised by microbial complications including local or overt infection, delayed healing and spread of multiresistant germs. Therefore, antimicrobial wound management is a major challenge that continues to require new solutions against microbes and their biofilms. As systemic antibiotics can barely penetrate into wound biofilms and topically applied ones can easily lead to sensitisation, antisepsis is the method of choice to treat germs in wounds. This brief review discusses the role of antiseptics in reducing bioburden in chronic wounds. Balancing antimicrobial potency and tolerability of antiseptic procedures is critical in wound therapy. However, antiseptics alone may not be able to achieve wound healing without addressing other factors regarding the patient's general health or the wound's physical environment. Although the precise role of bioburden in chronic wounds remains to be evaluated, planktonic as well as biofilm-bound microbes are indications for antiseptic intervention. Octenidine dihydrochloride and polyhexanide are the most effective, as well as best tolerated, antiseptics in wound management today, and new strategies to reduce bacterial wound burden and support the body's immune response are being developed.
Octenidine dihydrochloride, a modern antiseptic for skin, mucous membranes and wounds
Skin Pharmacol Physiol2010;23(5):244-58.PMID:20484966DOI:10.1159/000314699.
Octenidine dihydrochloride (octenidine) was introduced for skin, mucous membrane and wound antisepsis more than 20 years ago. Until now, a wealth of knowledge has been gained, including in vitro and animal studies on efficacy, tolerance, safety and clinical experience both from case reports and prospective controlled trials. Nowadays, octenidine is an established antiseptic in a large field of applications and represents an alternative to older substances such as chlorhexidine, polyvidone-iodine or triclosan. The review is based on the current literature and unpublished original data as well.
Consensus on Wound Antisepsis: Update 2018
Skin Pharmacol Physiol2018;31(1):28-58.PMID:29262416DOI:10.1159/000481545.
Wound antisepsis has undergone a renaissance due to the introduction of highly effective wound-compatible antimicrobial agents and the spread of multidrug-resistant organisms (MDROs). However, a strict indication must be set for the application of these agents. An infected or critically colonized wound must be treated antiseptically. In addition, systemic antibiotic therapy is required in case the infection spreads. If applied preventively, the Wounds-at-Risk Score allows an assessment of the risk for infection and thus appropriateness of the indication. The content of this updated consensus recommendation still largely consists of discussing properties of Octenidine dihydrochloride (OCT), polihexanide, and iodophores. The evaluations of hypochlorite, taurolidine, and silver ions have been updated. For critically colonized and infected chronic wounds as well as for burns, polihexanide is classified as the active agent of choice. The combination 0.1% OCT/phenoxyethanol (PE) solution is suitable for acute, contaminated, and traumatic wounds, including MRSA-colonized wounds due to its deep action. For chronic wounds, preparations with 0.05% OCT are preferable. For bite, stab/puncture, and gunshot wounds, polyvinylpyrrolidone (PVP)-iodine is the first choice, while polihexanide and hypochlorite are superior to PVP-iodine for the treatment of contaminated acute and chronic wounds. For the decolonization of wounds colonized or infected with MDROs, the combination of OCT/PE is preferred. For peritoneal rinsing or rinsing of other cavities with a lack of drainage potential as well as the risk of central nervous system exposure, hypochlorite is the superior active agent. Silver-sulfadiazine is classified as dispensable, while dyes, organic mercury compounds, and hydrogen peroxide alone are classified as obsolete. As promising prospects, acetic acid, the combination of negative pressure wound therapy with the instillation of antiseptics (NPWTi), and cold atmospheric plasma are also subjects of this assessment.
Use of Octenidine dihydrochloride in meticillin-resistant Staphylococcus aureus decolonisation regimens: a literature review
J Hosp Infect2010 Mar;74(3):199-203.PMID:20060619DOI:10.1016/j.jhin.2009.08.022.
Decolonisation of patients colonised with meticillin-resistant Staphylococcus aureus (MRSA) is one of the recommended methods for controlling MRSA in hospitals but there is a limited choice of agents that can be used. Octenidine dihydrochloride is a relatively new antiseptic that has been used for MRSA decolonisation in some countries. On reviewing available literature on its use for MRSA decolonisation, only four observational studies were found. All of these were small studies, which differed in study design. MRSA decolonisation rates of 6-75% have been reported. Patients with wound colonisation were included in these studies but it was not clear if the hair was treated in two of these. Octenidine appears to be as effective as chlorhexidine for MRSA decolonisation with fewer adverse effects, but large randomised trials incorporating octenidine as a skin disinfectant for MRSA decolonisation need to be undertaken to confirm its usefulness in clinical settings.
