Antiseptics
Antiseptic agent is a substance which kills or
inhibits the growth of disease-causing bacteria and other microorganisms.
It is essentially nontoxic to to be applied to the skin or mucous membranes.
(Disinfectant including cresol, bleaching powder, and phenol is in general
toxic to cells of the body).
Common antiseptic agents are Benzalkonium Chloride, Cetrimide,
Chlorhexidine, Hexachlorophene, Iodine Compounds, Mercury Compounds
(Thimerosol), Alcohol and Hydrogen Peroxide, Hexamine Hippurate, Triclosan,
Cetylpyridinium Chloride, And Dequalinium. Other substances which can
be used for antiseptic purpose include Boric acid and volatile oils
such as Methyl Salicylate.
Hexachlorophene and Benzalkonium Chloride are used
primarily in hand or face washes. Benzalkonium Chloride must not be
applied to areas which have not been fully rinsed as it is inactivated
by organic compounds. Benzalkonium application many include disinfecting
instruments and preservativing drugs in low concentration form.
Iodine compounds have the widest spectrum of antiinfectives
against bacteria, fungi, spores, protozoa, viruses, and yeasts. Aqueous
iodine are less effective than alcoholic solutions, but alcoholic component
is drying and irritating to abraided skin. Povidone iodine is convenient
to use as it is less irritating, but not as effective.
Chlorhexidine is used as a safe antiseptic or disinfectant
to apply to prevent body infection and in oral rinses for treating sore
gums and mouth ulcers and preventing plaque on teeth. It is used in
the form of acetate, gluconate or hydrochloride, either alone or in
combination with others such as cetrimide.
Cetrimide is an antiseptic agent with detergent properties.
It has the wide spectrum of antiinfectives against bacteria and fungi.
It is used as an ingredient of shampoos for treating seborrhoea and
psoriasis. A very dilute solution can be applied topically for the relief
of sore gums.
Hippuric Acid, an amino acid glycine, is excreted from
the body and is used in urinary system drugs. Hexamine hippurates is
helpful for preventing and treating infections of the urinary system;
it acts by being transformed to formaldehyde.
Triclosan is a very popular antibacterial agent. It
is used in hospitals for cleansing and disinfecting the skin of patients
and surgeons. It is used in cosmetics, household goods and personal
care products. It is also used in plastics and textiles for antibacterial
activity purpose.
Cetylpyridinium chloride is used in oral rinses for
cleaning mouth and treating minor throat or mouth infections and teething
problems.
Dequalinium chloride is antiinfectives against bacteria
and fungi. It is used in treating bacterial or fungal infections of
mouth and throat.
