Composition:
Miconazole nitrate 20 mg/g and Hydrocortisone 10 mg/g.
INDICATIONS:
Organisms which are susceptible to miconazole are dermatophytes and pathogenic yeasts (e.g. Candida spp.). Also many Gram-positive bacteria including most strains of Streptococcus and Staphylococcus.
DOSAGE AND ADMINISTRATION:
For topical administration.
Apply the cream two or three times a day to the affected area, rubbing in gently until the cream has been absorbed by the skin.
Because of its corticosteroid content avoid long-term treatment with THIS CREAM. Once the inflammatory symptoms have disappeared (after about 7 days),
treatment can be continued where necessary with miconazole nitrate 2% cream or miconazole nitrate 2% powder. Treatment should be continued without interruption until the lesion has completely disappeared (usually after 2 to 5 weeks).
If after about 7 days’ application, no improvement has occurred, cultural isolation of the offending organism should be followed by appropriate local or systemic antimicrobial therapy.
The same dosage applies to both adults and children.
Elderly
Natural thinning of the skin occurs in the elderly, hence corticosteroids should be used sparingly and for short periods of time.
Pediatrics
In infants and children, caution is advised when THIS CREAM is applied to extensive surface areas or under occlusive dressings including baby napkins (diapers). In infants, long term continuous topical corticosteroid therapy should be avoided.
CONTRAINDICATIONS:
WARNINGS AND PRECAUTIONS:
Visual disturbance may be reported with systemic and topical corticosteroid use. If a patient presents with symptoms such as blurred vision or other visual disturbances, the patient should be considered for referral to an ophthalmologist for evaluation of possible causes which may include cataract, glaucoma or rare diseases such as central serous chorioretinopathy (CSCR) which have been reported after use of systemic and topical corticosteroids.
INTERACTION:
Miconazole administered systemically is known to inhibit CYP3A4/2C9. Due to the limited systemic availability after topical application, clinically relevant interactions are rare. However, in patients on oral anticoagulants, such as warfarin, caution should be exercised and anticoagulant effect should be monitored.
Miconazole is a CYP3A4 inhibitor that can decrease the rate of metabolism of hydrocortisone. Serum concentrations of hydrocortisone may be higher with the use of THIS CREAM compared with topical preparations containing hydrocortisone alone.
PREGNANCY:
Clinical data on the use of THIS CREAM Cream in pregnancy are limited. In animals, corticosteroids are known to cross the placenta and consequently can affect the foetus. Administration of corticosteroids to pregnant animals can cause abnormalities of foetal development. The relevance of these findings to humans has not been established.
As a precautionary measure, it is preferable to avoid the use of THIS CREAM during pregnancy. Treatment of large surfaces and the application under occlusive dressing is not recommended.
BREAST-FEEDING
There are no adequate and well-controlled studies on the topical administration of THIS CREAM Cream during
breastfeeding. It is not known whether concomitant topical administration of THIS CREAM Cream to the skin could result in sufficient systemic absorption to produce detectable quantities of hydrocortisone and miconazole in breast milk in humans.
A risk to the newborn child cannot be excluded.
A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from THIS CREAM therapy taking into account the benefit of breast feeding for the child and the benefit of therapy for the woman. Treatment of large surfaces and the application under occlusive dressing is not recommended.

OVERDOSE:
Prolonged and excessive use can result in skin irritation, which usually disappears after discontinuation of therapy.
Topically applied corticosteroids can be absorbed in sufficient amounts to produce systemic effects.
PHARMACOLOGICAL PROPERTIES:
Pharmacodynamic effects:
Miconazole nitrate is active against dermatophytes and pathogenic yeasts, and many Gram-positive bacteria.
Hydrocortisone is an anti-inflammatory steroid. Its anti-inflammatory action is due to reduction in the vascular component of the inflammatory response, suppression of migration of polymorphonuclear leukocytes, and reversal of increased capillary permeability. The vasoconstrictor action of hydrocortisone may also contribute to its anti-inflammatory activity.
Pharmacokinetic properties:
Absorption:
Miconazole remains in the skin after topical application for up to 4 days. Systemic absorption of miconazole is limited, with a bioavailability of less than 1% following topical application of miconazole. Plasma concentrations of miconazole and/or its metabolites were measurable 24 and 48 hours after application. Approximately 3% of the dose of hydrocortisone is absorbed after application on the skin.
Distribution:
Absorbed miconazole is bound to plasma proteins (88.2%) and red blood cells (10.6%). More than 90% of hydrocortisone is bound to plasma proteins.
Metabolism and elimination:
The small amount of miconazole that is absorbed is eliminated predominantly in faeces as both unchanged drug and metabolites over a four-day post-administration period. Smaller amounts of unchanged drug and metabolites also appear in urine.
The half-life of hydrocortisone is about 100 minutes. Metabolism takes place in the liver and tissues and the metabolites are excreted with the urine, mostly as glucuronides, together with a very small fraction of unchanged hydrocortisone.
INCOMPATIBILITIES:
Contact should be avoided between latex products such as contraceptive diaphragms or condoms and THIS CREAM since the constituents of THIS CREAM may damage the latex.
STORAGE CONDITIONS: Store at temperature below 25°c.
PRESENTATION: MYCONAZOL PLUS cream is supplied in a tube containing 20 g or 40g of the cream.
