Curatoderm 4 micrograms/g Lotion
Each gram of lotion contains 4 micrograms of tacalcitol (as monohydrate).
Excipients with known effect
1 g of lotion contains 100 mg of propylene glycol and 0.2 mg of dodecyl gallate.
For the full list of excipients, see section 6.1.
White, thin emulsion.
Curatoderm Lotion is indicated for the treatment of psoriasis vulgaris in adults, especially on the scalp.
Adults and the Elderly:
Apply once daily to the affected areas, preferably at bedtime. The amount applied should not exceed 10 ml of lotion/day. When used together with Curatoderm Ointment, the total dose of tacalcitol should not exceed 280 μg/week (e.g. 30 ml of Curatoderm Lotion plus 40 g of Curatoderm Ointment). Normally duration of treatment depends on the severity of the lesions and should be decided by the physician.
There is clinical trial experience with continuous and intermittent treatment in adults with tacalcitol ointment up to 18 months, and with tacalcitol lotion for up to 8 weeks.
Curatoderm Lotion can be used on all areas of the body (including face, hairline, scalp, axilla and other flexures).
Not recommended. There is limited clinical experience with tacalcitol in children.
• Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
• Patients with hypercalcaemia or other known disorders of calcium metabolism.
At the doctor's discretion, in patients at risk of hypercalcaemia, or patients taking high Vitamin D preparations (in excess of 500 IU vitamin D) albumin corrected serum calcium levels should be closely monitored. Treatment should be stopped if hypercalcaemia occurs. Serum calcium levels should also be monitored in patients with renal impairment.
Care should be exercised in patients with generalised pustular or erythrodermic exfoliative psoriasis as the risk of hypercalcaemia may be enhanced.
When applying to the face avoid contact with the eyes. If Curatoderm Lotion accidentally comes into contact with the eyes, thorough rinsing with water is recommended. Patients should be advised to wash their hands after applying the lotion to avoid inadvertent transfer to other parts of the body.
This medicine contains 100 mg propylene glycol and 0.2 mg dodecyl gallate in each gram.
Propylene glycol may cause irritation of the skin.
Dodecyl gallate may be mildly irritant to the skin, the eyes and mucous membrane.
Instruct patients not to smoke or go near naked flames - risk of severe burns. Fabric (clothing, bedding, dressings etc) that has been in contact with this product burns more easily and is a serious fire hazard. Washing clothing and bedding may reduce product build-up but not totally remove it.
No interactions are likely in patients using multivitamin preparations with up to 500 IU vitamin D.
UVB radiation can be combined with Curatoderm Lotion. This approach increases the efficacy of tacalcitol treatment and shortens the radiation period. UV radiation should be given in the morning and Curatoderm Lotion at bedtime. There has been limited experience of the concomitant use of tacalcitol with topical corticosteroids, urea, emollients, dithranol cream and PUVA.
For Curatoderm Lotion no clinical data on exposed pregnancies are available. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development. Caution should be exercised when prescribing to pregnant women.
It is not known whether tacalcitol is excreted in human milk. Given the low systemic exposure in humans following topical treatment with tacalcitol, it is probably not necessary to stop breast-feeding during treatment, unless the breast area is affected. In that case, either the breast area should not be treated in lactating women who are breast-feeding, or breast-feeding should be stopped.
The data given for frequency of adverse reactions is based on the following categories:
Very common (≥ 1/10)
Common (≥ 1/100 to < 1/10)
Uncommon (≥ 1/1,000 to < 1/100)
Rare (≥ 1/10,000 to 1/1,000)
Very rare (< 1/10,000)
Not known (frequency cannot be estimated from the available data)
Metabolism and nutrition disorders
Frequency unknown: Hypercalcaemia
Skin and subcutaneous tissue disorders:
Rare: Skin irritation (e.g. burning, erythema), itching, contact dermatitis, worsening of psoriasis.
Skin irritation and itching are generally mild and transient.
Reporting of suspected adverse 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, Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow card in the Google Play or Apple App Store.
Overdosing by ingestion of a lotion is very unlikely. It cannot be excluded that topical application of excessive amounts may lead to hypercalcaemia. In this case Curatoderm treatment and other possible vitamin D or calcium supplement intakes must be stopped until serum calcium returns to normal.
Pharmacotherapeutic group: Other antipsoriatics for topical use, ATC Code: D05A X04.
Tacalcitol is a vitamin D3 derivative, which inhibits keratinocyte hyper-proliferation and induces differentiation of these cells. The normalisation of these mechanisms is the basis for the efficacy in the treatment of psoriasis. In biopsies from patients treated with tacalcitol specific indicators for inflammation were improved. Tacalcitol binds to the keratinocyte vitamin D receptor to the same extent as natural active vitamin D3.
Single or repeated application of tacalcitol ointment in humans results in less than 0.5% of the drug being systemically absorbed through psoriatic skin. Tacalcitol is completely bound to plasma proteins (vitamin D binding protein). The main metabolite is 1α, 24, 25 (OH)3 vitamin D3, a metabolite shared with the natural active vitamin, with 5-10 times less vitamin D activity. Tacalcitol and metabolites are excreted mainly in the faeces in rat and dog studies with excretion in urine in man. It cannot therefore be excluded that if there is sufficient systemic absorption accumulation may occur in patients with renal failure.
The toxic effects of tacalcitol are typical of those expected from excessive pharmacological activity of calciferols and resultant hypercalcaemia. The NOEL in rats treated subcutaneously for 12 months was 4 ng/kg/day.
Reproductive toxicity studies in rats and rabbits revealed no teratogenic effects.
Tacalcitol was negative in a battery of in vitro mutagenicity studies.
