5. Some common antiseptics & their actions :
, including ethanol and 2-propanol/isopropanol
are sometimes referred to as . They are used
to disinfect the skin before injections are given, among
other uses.
is used as a skin antiseptic and
to treat inflammation of the gums (gingivitis).
is used as a 6% (20 Vols) solution to
clean and deodorize wounds and ulcers. More commonly,
3% solutions of hydrogen peroxide have been used in
household first aid for scrapes, etc.
6. is usually used in an alcohol solution
(called ) or as Lugol's iodine
solution as a pre- and post-operative antiseptic.
The great advantage of iodine antiseptics is their
wide scope of antimicrobial activity, killing all
principal pathogens and, given enough time,
even spores, which are considered to be the
most difficult form of microorganisms to be
inactivated by disinfectants and antiseptics.
, currently
increasingly used in continental Europe, often as
a chlorhexidine substitute.
7. is an
antimicrobial compound suitable for clinical use in critically
colonized or infected acute and chronic wounds. The
physicochemical action on the bacterial envelope prevents
or impedes the development of resistant bacterial strains.
is a mild antiseptic.
is a sodium hypochlorite solution,
originally also containing boric acid to lower pH. It is mostly
used on live tissues for cleaning wounds off bacteria, fungi
and viruses. Because of practicality of preparation and
lower cost, it is largely used on Veterinary Medicine
treatments. It's colourless and doesn't stain the animal's fur,
so it doesn't affect its aesthetics or commercial value.

12. An antifungal medication, also known as an
antimycotic medication, is a pharmaceutical
fungicide or fungistatic used to treat and
prevent mycosis such as
serious
systemic infections such as cryptococcal
meningitis, and others.
13. How antifungal medicines work :
Antifungal medicines work by either:
• Killing the fungal cells – for example, by affecting a
substance in the cell walls, causing the contents of
the fungal cells to leak out and the cells to die.
Or,
• Preventing the fungal cells growing and
reproducing.

15. Classes
Polyene antifungals
A polyene is a molecule with multiple conjugated double bonds. A polyene antifungal
is a macrocyclic polyene with a heavily hydroxylated region on the ring opposite the
conjugated system. This makes polyene antifungals amphiphilic.
• Amphotericin B
• Candicidin
• Filipin – 35 carbons, binds to cholesterol (toxic)
• Hamycin
• Natamycin – 33 carbons, binds well to ergosterol
• Nystatin
• Rimocidin
16. Imidazole, triazole, and thiazole antifungals
Azole antifungal drugs (except for abafungin)
inhibit the enzyme lanosterol 14 α-
demethylase; the enzyme necessary to
convert lanosterol to ergosterol. Depletion of
ergosterol in fungal membrane disrupts the
structure and many functions of fungal
membrane leading to inhibition of fungal
growth.
19. Allylamines
Allylamines inhibit squalene epoxidase, another enzyme required
for ergosterol synthesis. Examples include amorolfin, butenafine,
naftifine, and terbinafine.
Echinocandins
Echinocandins may be used for systemic fungal infections in
immunocompromised patients, they inhibit the synthesis of glucan in
the cell wall via the enzyme 1,3-Beta-glucan synthase:
• Anidulafungin
• Caspofungin
• Micafungin
20. Others :
- have been shown to possess antifungal
properties.
– has antifungal properties, but must
be combined with a keratolytic agent such as in
Whitfield's ointment.
– (ciclopirox olamine) – is a
hydroxypyridone antifungal that interferes with
active membrane transport, cell membrane integrity,
and fungal respiratory processes. It is most useful
against tinea versicolour.
21. – an antimetabolite
pyrimidine analog.
– binds to polymerized microtubules
and inhibits fungal mitosis.
– discontinued due to the emergence of
more modern antifungals with fewer side effects.
– a thiocarbamate antifungal, which
inhibits fungal squalene epoxidase (similar
mechanism to allylamines like terbinafine).
22. – an unsaturated fatty acid derived
from natural castor oil; fungistatic, antibacterial,
antiviral, and inhibits Candida morphogenesis.
– a triarylmethane dye, it has antibacterial,
antifungal, and anthelmintic properties and was
formerly important as a topical antiseptic.
has antifungal properties.
- pyrimidine synthesis inhibitor.
disrupts fungal cell membrane dynamics by
interacting with ergosterol.
