Audavate 0.1% W/W Ointment
Audavate 0.1% w/w Ointment
One gram of ointment contains 1 mg of betamethasone (0.1% w/w) as valerate. For a full list of excipients, see section 6.1.
4.1 Therapeutic indications
Audavate preparations are indicated for the treatment of: eczema in children over 1 year elderly and adults; including atopic and discoid eczemas; prurigo nodularis; psoriasis (excluding widespread plaque psoriasis); neurodermatoses, including lichen simplex, lichen planus; seborrhoeic dermatitis; contact sensitivity reactions; discoid lupus erythematosus and they may be used as an adjunct to systemic steroid therapy in generalised erythroderma.
In general, ointment preparations are particularly appropriate for dry, lichenified or scaly skin conditions whereas a cream preparation may be more suitable in the case of moist or weeping lesions.
4.2 Posology and method of administration
For topical use only.
If no improvement is seen after two to four weeks, the diagnosis should be reconsidered and specialist referral may be necessary.
Adults, adolescents and the elderly
A small quantity of Audavate should be applied to the affected area one to three times daily or as directed by physician until improvement occurs. It may then be possible to maintain improvement by applying once a day, or even less often, or by using the appropriate ready diluted (1 in 4) preparation, Audavate RD 0.025% Ointment.
Allow adequate time for absorption after each application before applying an emollient. If no improvement is seen within two to four weeks, reassessment of the diagnosis or referral, may be necessary.
In the more resistant lesions, such as the thickened plaques of psoriasis on elbows and knees, the effect of Audavate can be enhanced, if necessary, by occluding the treatment area with polythene film. Overnight occlusion only is usually adequate to bring about a satisfactory response in such lesions; thereafter improvement can usually be maintained by regular application without occlusion.
Therapy with betamethasone valerate should be gradually discontinued once control is achieved and an emollient continued as maintenance therapy. Rebound of pre-existing dermatoses can occur with abrupt discontinuation of betamethasone valerate.
Patients who frequently relapse
Once an acute episode has been treated effectively with a continuous course of topical corticosteroid, intermittent dosing (apply once a day twice a week without occlusion) may be considered. This has been shown to be helpful in reducing the frequency of relapse. Application should be continued to all previously affected sites or to known sites of potential relapse. This regimen should be combined with routine daily use of emollients. The condition and the benefits and risks of continued treatment must be re-evaluated on a regular basis.
Betamethasone valerate is contraindicated in children under one year of age.
Children are more likely to develop local and systemic side effects of topical corticosteroids and, in general, require shorter courses and less potent agents than adults; Courses should be limited to five days. Occlusion should not be used.
Care should be taken when using betamethasone valerate to ensure the amount applied is the minimum that provides therapeutic benefit.
For topical administration.
Clinical studies have not identified differences in responses between the elderly and younger patients. The greater frequency of decreased hepatic or renal function in the elderly may delay elimination if systemic absorption occurs. Therefore the minimum quantity should be used for the shortest duration to achieve the desired clinical benefit.
Renal / Hepatic Impairment
In case of systemic absorption (when application is over a large surface area for a prolonged period) metabolism and elimination may be delayed therefore increasing the risk of systemic toxicity. Therefore the minimum quantity should be used for the shortest duration to achieve the desired clinical benefit.
Rosacea, acne vulgaris, pruritus without inflammation, perioral dermatitis and use in widespread plaque psoriasis. Primary cutaneous viral infections (e.g. herpes simplex, chickenpox). Hypersensitivity to any component of the preparation.
The use of Audavate skin preparations is not indicated in the treatment of primarily infected skin lesions caused by infections with fungi (e.g. candidiasis, tinea); or bacteria (e.g. impetigo); primary or secondary infections due to yeast; peri-anal and genital pruritus; dermatoses in children under 1 year of age, including dermatitis and napkin eruptions.
Long-term continuous topical therapy should be avoided where possible, particularly in infants and children, as adrenal suppression, with or without clinical features of Cushing's syndrome and reversible hypothalamic-pituitary-adrenal (HPA) axis, can occur even without occlusion. In this situation, topical steroids should be discontinued gradually under medical supervision by reducing the frequency of application, or by substituting a less potent corticosteroid because of the risk of adrenal insufficiency (see section 4.8 Undesirable Effects and Section 4.9 Overdose).
• Risk factors for increased systemic effects are:
• Potency and formulation of topical steroid
• Duration of exposure
• Application to a large surface area
• Use on occluded areas of skin e.g. on intertriginous areas or under occlusive dressings (in infants the nappy may act as an occlusive dressing)
• Increasing hydration of the stratum corneum
• Use on thin skin areas such as the face
• Use on broken skin or other conditions where the skin barrier may be impaired
• In comparison with adults, children may absorb proportionally larger amounts of topical corticosteroids and thus be more susceptible to systemic adverse effects. This is because children have an immature skin barrier and a greater surface area to body weight ratio compared with adults.
The face, more than other areas of the body, may exhibit atrophic changes after prolonged treatment with potent topical corticosteroids. This must be borne in mind when treating such conditions as psoriasis, discoid lupus erythematosus and severe eczema. Therefore, treatment courses should be limited to five days and occlusion should not be used
If applied to the eyelids, care is needed to ensure that the preparation does not enter the eye, as glaucoma and cataract might result from repeated exposure.
If used in childhood, or on the face, courses should be limited to five days and occlusion should not be used.
Topical corticosteroids may be hazardous in psoriasis for a number of reasons including rebound relapses, development of tolerance, risk of generalised pustular psoriasis and development of local or systemic toxicity due to impaired barrier function of the skin. If used in psoriasis careful patient supervision is important.
Appropriate antimicrobial therapy should be used whenever treating inflammatory lesions which have become infected. Any spread of infection requires withdrawal of topical corticosteroid therapy and systemic administration of antimicrobial agents. Bacterial infection is encouraged by the warm, moist conditions within skin folds or caused by induced by occlusive dressings, and so the skin should be cleansed before a fresh dressing is applied.
Betamethasone valerate should be used with caution in patients with a history of local hypersensitivity to other corticosteroids.
If signs of hypersensitivity appear, application should stop immediately. Local hypersensitivity reactions (see section 4.8) may resemble symptoms of the condition under treatment.Exacerbation of symptoms may occur.
Topical corticosteroids are sometimes used to treat the dermatitis around chronic leg ulcers. However, this use may be associated with a higher occurrence of local hypersensitivity reactions and an increased risk of local infection.
There have been a few reports in the literature of the development of cataracts in patients who have been using corticosteroids for prolonged periods of time. Although it is not possible to rule out systemic corticosteroids as a known factor, prescribers should be aware of the possible role of corticosteroids in cataract development.
The least potent corticosteroid, which will control the disease, should be selected. None of these preparations contain lanolin. Audavate ointment and cream and the corresponding RD 0.025% preparations do not contain parabens.
Co-administered drugs that can inhibit CYP3A4 (e.g. ritonavir, itraconazole) have been shown to inhibit the metabolism of corticosteroids leading to increased systemic exposure. The extent to which this interaction is clinically relevant depends on the dose and route of administration of the corticosteroids and the potency of the CYP3A4 inhibitor.
There is inadequate evidence of safety. Topical administration of corticosteroids to pregnant animals can cause abnormalities of fetal development including cleft palate and intrauterine growth retardation. There might therefore be a very small risk of such effects in the human fetus. Administration of Betamethasone valerate during pregnancy should only be considered if the excpected benefit to the mother out weighsthe risk to the foetus. The minimum quantity should be used for the minimum duration.
This product should not be used during pregnancy or lactation unless considered essential by the physician
The safe use of topical corticosteroids during lactation has not been established.
It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable amounts in breast milk. Administration of betamethasone valerate during lactation should only be considered if the expected benefit to the mother outweighs the risk to the infant. If used during lactation betamethasone valerate should not be applied to the breasts to avoid accidental ingestion by the infant.
There have been no studies to investigate the effect of betamethasone valerate on driving performance or the ability to operate machinery.
A detrimental effect on such activities would not be anticipated from the adverse reaction profile of topical betamethasone valerate.
Adverse events are listed below by MeDRA system organ class and frequency. Frequencies are defined as: very common (^ 1/10), common (^ 1/100 and <1/10), uncommon 1/1000 and <1/100), rare (^ 1/10,000 and <1/1000) and very rare (<1/10,000) including isolated reports. Very common, common and uncommon events were generally determined from clinical trial data. The background rates in placebo and comparator groups were not taken into account when assigning frequency categories to adverse events derived from clinical trial data, since these rates were generally comparable to those in the active treatment group. Rare and very rare events were generally determined from spontaneous data.
Infections and Infestations
Very rare Opportunistic infection
Very rare: Hypersensitivity, generalised rash
If signs of hypersensitivity appear, application should stop immediately.
Very rare: Features of Cushing's syndrome.
Delayed weight gain/growth retardation in children, osteoporosis, glaucoma, hyperglycaemia/glucosuria, cataract,hypertension, increased weight/obesity, decreased endogenous cortisol levels, alopecia, trichorrhexis
As with other topical corticosteroids, prolonged use of large amounts or treatment of extensive areas can result in sufficient systemic absorption to produce suppression of the HPA axis and the clinical features of Cushing's syndrome (see Section 4.4 Special Warnings and Precautions for use). These effects are more likely to occur in infants and children, and if occlusive dressings are used. In infants the napkin may act as an occlusive dressing.
Common: Local skin burning/skin pain and pruritus.
Very rare: erythema, rash, urticaria , local atrophic changes in the skin such as thinning*, skin wrinkling*, skin dryness*, striae* and dilatation of the superficial blood vessels (telangiectasias)* may be caused by prolonged and intensive treatment with highly active corticosteroid preparations, particularly when occlusive dressings are used or when skin folds are involved.
Pigmentation changes, hypertrichosis, allergic contact dermatitis, exacerbation of symptoms, pustular psoriasis (due to treatment of psoriasis with corticosteroids or its withdrawal: see Section 4.4. Special Warnings and Precautions for use)
Very rare Application site irritation/pain *Skin features secondary to local and/or systemic effects of hypothalamic-pituitary adrenal (HPA) axis suppression.
Reporting of suspected reactions:
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.
Acute overdosage is very unlikely to occur. However, in the case of chronic overdosage or misuse the features of Cushing's syndrome may appear and in this situation topical steroids should be discontinued gradually under medical supervision (see Section 4.4 Special Warnings and Precautions for use).
In the event of overdose, betamethasone valerate should be withdrawn gradually by reducing the frequency of application, or by substituting a less potent corticosteroid because of the risk of glucocorticosteroid insufficiency.
Further management should be as clinically indicated or as recommended by the national poisons centre, where available.
ATC Code: D07 AC01 (Corticosteroid, potent,(group III))
Topical corticosteroids act as anti-inflammatory agents via multiple mechanisms to inhibit late phase allergic reactions including decreasing the density of mast cells, decreasing chemotaxis and activation of eosinophils, decreasing cytokine production by lymphocytes, monocytes, mast cells and eosinophils, and inhibiting the metabolism of arachidonic acid.
Betamethasone valerate is an active corticosteroid with topical anti-inflammatory activity antipruritic, and vasoconstrictive properties.
Topical corticosteroids can be systemically absorbed from intact healthy skin. The extent of percutaneous absorption of topical corticosteroids is determined by many factors, including the vehicle and the integrity of the epidermal barrier. Occlusion, inflammation and/or other disease processes in the skin may also increase percutaneous absorption.
The use of pharmacodynamic endpoints for assessing the systemic exposure of topical corticosteroids is necessary because circulating levels are well below the level of detection.
Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to systemically administered corticosteroids. They are metabolised, primarily in the liver.
Topical corticosteroids are excreted by the kidneys. In addition, some corticosteroids and their metabolites are also excreted in the bile.
5.3 Preclinical safety data
Subcutaneous administration of betamethasone valerate to mice or rats at doses ^0.1 mg/kg/day or rabbits at doses ^ 12 micrograms/kg/day during pregnancy produced fetal abnormalities including cleft palate and intrauterine growth retardation.
The effect on fertility of betamethasone valerate has not been evaluated in animals.
