Description:
Each
gram of Dermazene® Cream 1% contains 10 mg of hydrocortisone and
10 mg of iodoquinol in a cream base of purified water, propylene glycol,
cerasynt SE, amerchol L101, isopropyl palmitate, cetyl alcohol, arlacel
60, myrj 52, tween 60, sorbic acid, methyl paraben and propyl paraben.
Chemically, hydrocortisone is
[Pregn-4-ene-3, 20-dione,
11,17, 21-trihydroxy-(11ß)-]
with the molecular formula
(C21H30O5) and is represented
by the following structural formula:
and
iodoquinol, 5, 7-diiodo-8-quinolinol (C9H5I2NO) is represented by
the following structure:
Hydrocortisone
is an anti-inflammatory and antipruritic agent,while iodoquinol is
an antifungal and antibacterial agent.

Clinical
Pharmacology:
Hydrocortisone has anti-inflammatory, antipruritic
and vasoconstrictor properties. The mechanism of anti-inflammatory
activity is unclear. There is some evidence to suggest that a recognizable
correlation exists between vasoconstrictor potency and therapeutic
efficacy in man. Iodoquinol has both antifungal and antibacterial
properties.

Pharmacokinetics:
The extent of percutaneous absorption of
topical corticosteroids is determined by many factors including vehicle,
the integrity of the epidermal barrier, and the use of occlusive dressings.
Hydrocortisone can be absorbed from normal intact skin. Inflammation
and/or other inflammatory disease processes in the skin increase percutaneous
absorption. Occlusive dressings substantially increase the percutaneous
absorption of topical corticosteroids. Once absorbed through the skin,
hydrocortisone is metabolized in the liver and most body tissues to
hydrogenated and degraded forms such as tetrahydrocortisone and tetrahydrocortisol.
These are excreted in the urine, mainly conjugated as glucuronides,
together with a very small proportion of unchanged hydrocortisone.
There are no data available regarding the percutaneous absorption
of iodoquinol; however, following oral administration, 3-5% of the
dose was recovered in the urine as a glucuronide.

Indications
and Usage:
Based on a review of a related drug by the
National Research Council and subsequent FDA classification for that
drug, the indications are as follows: Possibly Effective:
Contact or atopic dermatitis; impetiginized eczema; nummular eczema;
infantile eczema; endogenous chronic infectious dermatitis; stasis
dermatitis; pyoderma; nuchal eczema and chronic eczematoid otitis
externa; acne urticata; localized or disseminated neurodermatitis;
lichen simplex chronicus; anogenital pruritus (vulvae, scroti, ani);
folliculitis; bacterial dermatoses; mycotic dermatoses such as tinea
(capitis, cruris, corporis, pedis); moniliasis, intertrigo. Final
classification of the less-than-effective indications requires further
investigation.

Contraindications:
Dermazene Cream is contraindicated in those
patients with a history of hypersensitivity to hydrocortisone, iodoquinol
or any other components of the preparation.

Warnings
and Precautions:
For external use only. Keep away from eyes.
If irritation develops, the use of Dermazene Cream should be discontinued
and appropriate therapy instituted. Staining of the skin and fabrics
may occur. If extensive areas are treated or if the occlusive technique
is used, the possibility exists of increased systemic absorption of
the corticosteroid, and suitable precautions should be taken. Children
may absorb proportionally larger amounts of the corticosteroids and
thus be more susceptible to systemic toxicity. Parents of pediatric
patients should be advised not to use tight-fitting diapers or plastic
pants on a child being treated in the diaper area, as these garments
may constitute occlusive dressings. Iodoquinol may be absorbed through
the skin and interfere with thyroid function tests. If such tests
are contemplated, wait at least one month after discontinuance of
therapy to perform these tests. The ferric chloride test for phenylketonuria
(PKU) can yield a false positive result if iodoquinol is present in
the diaper or urine. Prolonged use may result in overgrowth of non-susceptible
organisms requiring appropriate therapy. Keep out of reach of children.
Carcinogenesis, Mutagenesis, and Impairment of Fertility: Long
term animal studies have not been performed to evaluate the carcinogenic
potential or the effect on fertility of hydrocortisone or iodoquinol.
In vitro studies to determine mutagenicity with hydrocortisone have
revealed negative results. Mutagenicity studies have not zbeen conducted
with iodoquinol.
Pregnancy Category C: Animal reproductive studies have not
been conducted with Dermazene Cream. It is not known whether Dermazene
Cream can cause fetal harm when administered to a pregnant woman or
can affect reproductive capacity. Dermazene Cream should be given
to a pregnant woman only if clearly needed.
Nursing Mothers: It is not known whether this drug is excreted
in human milk. Because many drugs are excreted in human milk, caution
should be exercised when Dermazene Cream is administered to a nursing
woman.
Pediatric Use: Safety and effectiveness in children under the
age of 12 have not been established.

eruptions, Hypopigmentation, Perioral dermatitis, Allergic contact
dermatitis, Maceration of the skin, Secondary infection, Skin atrophy,
