etiology of diaper rash:
Occlusion , humidity and friction:
When the skin is wetted the fraction
coefficient of the skin increase more
damage from minor abrasion.
Wet skin decrease the normal barrier
and increase the permeability
Allow urine and stool to accelerate skin
-laundry soap, fabric softener , or bleach
used to wash reusable diaper irritant
Skin PH and fecal enzymes:
*normal skin ph is 4 – 5.5 .
*Skin occlusion elevate skin ph
*Bacteria on the skin metabolize
urine to form ammonia elevate skin ph
*at elevated ph the lipase and protease
enzyme found in feces activated
skin breakdown due to proteolytic
action, increase permeability of the skin
to bile salts which cause skin irritation
Candidal growth :
Candida albicans has extended from infant
GIT reservoir to affect the diaper area by
feces contact with skin, the recurrence is
likely to occur
Such as psoriasis , atopic dermatitis,

,erosion ,lesion) require referral.
If more than 7 days secondary infection with
Candida, especially if the skin is broken
Nature of diaper (the occlusive nature of
diapers helps to facilitate transcutaneous
absorption of medication).
-Infant don’t metabolize or detoxify
medications as well as adult.
Many enzyme systems are absent or deficient
-The diaper area is relatively large
percentage of the infant’s body
Conclusion: Because of all these
factors , pharmacists must take
great care to use only safe &
Safe & effective medication.
1. Skin protectants considered the only
ingredients safe &effective for diaper rash:
1. Talc( 45-100%)emollient effect on skin,
also absorbs sweat.
2. Corn starch (10-98%)protect skin
through absorbent action.
3. Zinc oxide (1-25%)/ Zinc oxide
1. talc & corn starch must be used with caution
since it is powder and could cause breathing
problems (keep away from child’s face).
2. Don’t use powder on broken skin.
3. avoid Mercury preparation because it is
hazardous over a large area.
4. The use of anti fungal, anti bacterial,
external analgesics, hydrocortisone should be
In persistent or especially bad
rashes, an antifungal cream often
has to be used. In cases that the
rash is more of an irritation, a
mild topical corticosteroid
preparation, e.g. hydrocortisone
cream, is used
