Clioquinol – Hydrocortisone

Antibacterial – Antifungal – Topical Corticosteroid

Action And Clinical Pharmacology: Clioquinol, the antimicrobial component of Vioform Hydrocortisone, is active against a broad spectrum of pathogenic microorganisms, including fungi (e.g., Candida, Microsporum, Trichophyton) and gram-positive bacteria (e.g., Staphylococci). Clioquinol has only a slight inhibitory effect on gram-negative bacteria. Clioquinol exerts a bacteriostatic, rather than a bactericidal action.

Hydrocortisone is a mild glucocorticoid with an anti-inflammatory, antiallergic and vasoconstrictive effect. In inflammatory skin diseases of widely varying type and origin it affords prompt relief and eliminates symptoms such as pruritus.

Vioform Hydrocortisone combines the antifungal and antibacterial actions of clioquinol with the anti-inflammatory and antipruritic effects of hydrocortisone for broad control of acute and chronic dermatologic disorders.

Indications And Clinical Uses: The initial treatment of corticosteroid-responsive inflammatory skin diseases complicated by bacterial and/or fungal infections, with appropriate systemic antibiotics if necessary. For example: atopic dermatitis, seborrheic dermatitis, contact dermatitis (dermatitis venenata), superficial forms of intertrigo, and dermatomycosis in which acute inflammation is a prominent feature.

The cream has a slightly drying effect primarily useful for moist, weeping lesions and in intertriginous areas.

Contra-Indications: Viral infections of the skin (e.g., chicken-pox, skin eruptions following vaccination, herpes simplex, herpes zoster), tuberculosis of the skin, syphilitic skin infections.

Known hypersensitivity to hydrocortisone or to corticosteroids in general, hydroxyquinolines, clioquinol, or other quinoline derivatives, iodine, as well as to any other components of Vioform Hydrocortisone (see Supplied).

Application to ulcerated areas.

Application to the eye.

Children: Do not use in children under 2 years of age.

Manufacturers’ Warnings In Clinical States: Pregnancy and Lactation: The safety of Vioform Hydrocortisone during pregnancy or lactation has not been established. Animal studies have shown that corticosteroids may induce fetal abnormalities in pregnant animals. The relevance of this finding to human use has not been elucidated. It is not known whether the active substance passes into the breast milk when applied topically. Therefore, the potential benefit of Vioform Hydrocortisone, if used during pregnancy (particularly in the first 3 months) or lactation, should be weighed against possible hazard to the fetus or the nursing infant.

Precautions: Application to relatively large and/or eroded areas, treatment for longer than 1 week, as well as use under occlusive dressings may lead to a marked increase in protein-bound iodine (PBI) and should be avoided.

Provided the preparation is used as recommended, unwanted systemic effects are unlikely to occur. On basic medical grounds, the possibility of a clinically important effect on adrenocortical function should nevertheless be borne in mind, particularly if the preparation is used under occlusion, over large areas of the body, in pediatrics and in patients undergoing prolonged therapy.

If no improvement occurs within 1 week, the therapy should be discontinued; it is then advisable to identify and treat the causative pathogens.

Vioform Hydrocortisone should not be used to treat bacterial or mycotic skin diseases in which acute inflammation is not present.

If in exceptional cases Vioform Hydrocortisone is applied in large amounts, the patient should be kept under regular medical supervision.

As a general rule, advise patients to inform subsequent physicians that they have been using corticosteroids.

Vioform Hydrocortisone should not be allowed to come into contact with the conjunctiva.

Vioform Hydrocortisone should not be used in the external auditory canal if the eardrum is perforated.

In patients suffering from hepatic and/or renal failure, caution is indicated.

Vioform Hydrocortisone may turn yellow when exposed to air and may cause staining of the skin, nails, hair or fabrics.

Interactions : Topical use of clioquinol, as well as other iodine-containing compounds, may increase the amount of protein-bound iodine (PBI) in patients with normal thyroid function and therefore may interfere with some thyroid function tests (such as PBI, radioactive iodine and butanol-extractable iodine). These tests should not be performed within a period shorter than 1 month following the use of Vioform Hydrocortisone. Other thyroid function tests, such as the T3 resin sponge test or the T4 determination, are unaffected by clioquinol.

The ferric chloride test for phenylketonuria may yield a false-positive result when clioquinol is present in the urine.

Adverse Reactions: Occasionally: signs of irritation such as burning sensation, itching or skin rash at the site of application; hypersensitivity reactions.

If an exacerbation or allergic type reaction occurs, treatment with Vioform Hydrocortisone should be discontinued.

Local adverse reactions reported during topical treatment with glucocorticoids (predominantly with glucocorticoids more potent thant hydrocortisone) include contact allergy, changes in skin pigmentation, secondary infections. Topically applied glucocorticoids may give rise to striae rubrae distensae, telangiectasia, purpura, skin atrophy, or steroid acne, especially if applied for prolonged periods of time, under occlusive dressings, to large areas or to permeable areas (e.g., face, axillae). However, serious side effects caused by topically applied hydrocortisone are rare unless it is used excessively.

Symptoms And Treatment Of Overdose: Symptoms and Treatment: Application to extensive and/or eroded areas of skin may lead to increased PBI values within 1 week. Elevated PBI values may also occur where relatively small areas of skin are treated for more than 1 week. If signs and symptoms resembling those of thyrotoxicosis occur, the preparation should be withdrawn at once.

Dosage And Administration: Apply Vioform Hydrocortisone to affected area in a thin layer 2 to 3 times daily.

Use of Vioform Hydrocortisone under occlusive dressings is not recommended as the resulting humid conditions may promote secondary infections with nonsensitive organisms and also may increase the possibility of elevated PBI.

Availability And Storage: Each tube of off-white water soluble cream contains: clioquinol 3% and hydrocortisone 1%. Nonmedicinal ingredients: cetyl alcohol, cetyl palmitate, glycerin, petrolatum, phenoxyethanol, sodium lauryl sulfate, stearyl alcohol and water. Sodium:
