Use above the recommended dose may cause elevated serum calcium which subsides when treatment is discontinued. The symptoms of hypercalcemia include polyuria, constipation, muscle weakness, confusion and coma.
Due to the content of calcipotriol, Psorcutan®* is contraindicated in patients with known disorders of calcium metabolism.
Should not be mixed with other medicinal products.
The estimation of the frequency of adverse reactions is based on a pooled analysis of data from clinical studies and spontaneous reporting.
The most frequently reported adverse reactions during treatment are pruritus, skin irritation and erythema.
Systemic reactions (hypercalcaemia and hypercalciuria) have been reported. The risk of developing such reactions increases if the recommended total dose is exceeded.
Adverse reactions are listed by MedDRA SOC and the individual adverse reactions are listed starting with the most frequently reported. Within each frequency grouping, adverse reactions are presented in the order of decreasing seriousness.

Approximately 25% of the patients treated with Psorcutan®* Ointment could experience an adverse reaction. These reactions are usually mild.

* Various types of rash reactions such as rash erythematous, rash maculo-papular, rash morbilliform, rash papular and rash pustular have been reported.
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 at: www.mhra.gov.uk/yellowcard.The effect on calcium metabolism is approximately 100 times less than that of the hormonally active form of vitamin D3.
Calcipotriol has shown maternal and foetal toxicity in rats and rabbits when given by the oral route at doses of 54 µg/kg/day and 12 µg/kg/day, respectively. The foetal abnormalities observed with concomitant maternal toxicity included signs indicative of skeletal immaturity (incomplete ossification of the pubic bones and forelimb phalanges, and enlarged fontanelles) and an increased incidence of supernumerary ribs.
There is insufficient pharmacokinetic data available to quantify the safety margin for the embryofoetal effects.
A dermal carcinogenicity study in mice and an oral carcinogenicity study in rats revealed no special hazard to humans.
In a study where albino hairless mice were repeatedly exposed to both ultraviolet (UV) radiation and dermally administered calcipotriol for 40 weeks at dose levels corresponding to 9, 30 and 90 µg/m2/day (equivalent to 0.25, 0.84, 2.5 times the maximum recommended daily dose for a 60 kg adult, respectively), a reduction in the time required for UV radiation to induce the formation of skin tumours was observed (statistically significant in males only), suggesting that calcipotriol may enhance the effect of UV radiation to induce skin tumours. The clinical relevance of these findings is unknown.
Psorcutan®* Ointment is indicated for the topical treatment of plaque psoriasis (psoriasis vulgaris) amenable to topical therapy.
ATC Code: D05A X02
Pharmacotherapeutic group: Antipsoriatics for topical use
Calcipotriol is a vitamin D derivative. In vitro data suggest that calcipotriol induces differentiation and suppresses proliferation of keratinocytes. This is the proposed basis for its effect in psoriasis.
Data from a single study containing 5 evaluable patients with psoriasis treated with 0.3-1.7 g of a 50 micrograms/g tritium labelled calcipotriol ointment suggested that less than 1% of the dose was absorbed.
However, total recovery of the tritium label over a 96 hour period ranged from 6.7 to only 32.6%, figures maximised by uncorrected chemiluminescence. There were no data on 3H tissue distribution or excretion from the lungs.
Effects on calcium metabolism
Due to the content of calcipotriol, hypercalcaemia may occur if the maximum weekly dose is exceeded. Care should be exercised in patients with other types of psoriasis, since hypercalcaemia has been reported in patients with generalised pustular or erythrodermic exfoliative psoriasis. Serum calcium is normalised when treatment is discontinued. The risk of hypercalcaemia is minimal when the dosage recommendations are followed. The maximum weekly dose in adults is 100 g of cream or ointment (equivalent to 5 mg of calcipotriol) or 60 ml of scalp solution (equivalent to 3 mg of calcipotriol). When cream, ointment or cutaneous solution are applied together, the total dose of calcipotriol should not exceed 5 mg per week.
Local adverse reactions
Psorcutan®* should not be applied to the face, as it may cause skin irritation
The patient must be instructed in correct use of the product to avoid accidental transfer to the face and eyes. Hands must be washed after each application to avoid accidental transfer to these areas.
UV exposure
During Psorcutan®* Ointment treatment, physicians are recommended to advise patients to limit or avoid excessive exposure to either natural or artificial sunlight. Psorcutan®* should be used with UV radiation only if the physician and patient consider that the potential benefits outweigh the potential risks.
Unevaluated use
Due to lack of data, Psorcutan®* should be avoided in guttate, erythrodermic, exfoliative and pustular psoriasis.
Due to lack of data, Psorcutan®* should be avoided in patients with severe liver and kidney disease.
Adverse reactions to excipients
Psorcutan®* ointment contains propylene glycol as an excipient which may cause skin irritation.
Calcipotriol has no or negligible influence on the ability to drive and to use machines.
| Adults: | Psorcutan®* Ointment should be applied to the affected area once or twice daily. For maximum benefit use the ointment twice daily. Maximum weekly dose should not exceed 100 g. |
| Children over 12 years: | Psorcutan®* Ointment should be applied to the affected area twice daily. Maximum weekly dose should not exceed 75 g. |
| Children aged 6 to 12 years: | Psorcutan®* Ointment should be applied to the affected area twice daily. Maximum weekly dose should not exceed 50 g. |
Children under 6 years: | There is limited experience of the use of Psorcutan®* Ointment in this age group. A maximum safe dose has not been established. |
These dose recommendations are based on extensive experience in adults. In respect of children, clinical experience in children has shown Psorcutan®* to be safe and effective over eight weeks at a mean dose of 15 g per week but with wide variability in dose among patients. Individual dose requirement depends on the extent of psoriasis but should not exceed the above recommendations. There is no experience of use of Psorcutan®* in combination with other therapies in children.
No special requirements.
