Ciclosporin
Brand names: Neoral, Sandimmun, Capimune, Deximune, Vanquoral
Ciclosporin is a calcineurin-inhibitor immunosuppressant used in rheumatology as a disease-modifying agent for severe rheumatoid arthritis and other autoimmune conditions unresponsive to first-line therapy.
Adult dose
Dose adjustments
§4.2 verbatim: 'Ciclosporin undergoes minimal renal elimination, and its pharmacokinetics are not extensively affected by renal impairment. However, due to its nephrotoxic potential, careful monitoring of renal function is recommended.' For NON-transplantation indications: 'With the exception of patients being treated for nephrotic syndrome, patients with impaired renal function should not receive ciclosporin. In nephrotic syndrome patients with impaired renal function, the initial dose should not exceed 2.5 mg/kg/day.' On-treatment rule: reduce the dose by 25 to 50% if eGFR falls more than 25% below baseline on more than one measurement, consider further reduction if the fall exceeds 35%, and discontinue if dose reduction does not improve eGFR within one month — 'These recommendations apply even if the patient's values still lie within the laboratory's normal range.' §4.4 adds that the rise in serum creatinine and urea is 'dose-dependent and reversible, usually responding to dose reduction'.
§4.2 verbatim: 'Ciclosporin is extensively metabolised by the liver. An approximate 2- to 3-fold increase in ciclosporin exposure may be observed in patients with hepatic impairment. Dose reduction may be necessary in patients with severe liver impairment to maintain blood levels within the recommended target range and it is recommended that ciclosporin blood levels are monitored until stable levels are reached.' §4.2 also requires determination of bilirubin and hepatic function parameters before starting, with close monitoring during treatment. (§4.4's hepatotoxicity paragraph was cut off at the source-fetch limit.)

Contraindications
- Hypersensitivity to the active substance or to any of the excipients listed in section 6.1 (§4.3)
- Combination with products containing Hypericum perforatum (St John's Wort) (§4.3)
- Combination with medicines that are substrates for the multidrug efflux transporter P-glycoprotein (Pgp) or the organic anion transporter proteins (OATP) and for which elevated plasma concentrations are associated with serious and/or life-threatening events, e.g. bosentan, dabigatran etexilate and aliskiren (§4.3)
- INCOMPLETE LIST: the fetched §4.3 ends mid-bullet at the source-fetch limit — check the SPC for any further contraindications before publishing
Side effects
- §4.8 summary: 'The principal adverse reactions observed in clinical trials and associated with the administration of ciclosporin include renal dysfunction, tremor, hirsutism, hypertension, diarrhoea, anorexia, nausea and vomiting. Many side effects associated with ciclosporin therapy are dose dependent and responsive to dose reduction.'
- Very common: hyperlipidaemia; tremor; headache (§4.8)
- Common: leucopenia; anorexia, hyperuricaemia, hyperkalaemia, hypomagnesaemia, hyperglycaemia; paraesthesia; convulsions (§4.8)
- Uncommon: anaemia, thrombocytopenia (§4.8)
- Rare: microangiopathic haemolytic anaemia, haemolytic uraemic syndrome (§4.8)
- Not known: thrombotic microangiopathy, thrombotic thrombocytopenic purpura (§4.8)
- Renal dysfunction — §4.4: 'an increase in serum creatinine and urea may occur during Capimune therapy. These functional changes are dose-dependent and reversible... During long-term treatment, some patients may develop structural changes in the kidney (e.g. interstitial fibrosis)'
- Infections — increased risk of viral, bacterial, fungal and parasitic infection, including reactivation of polyomavirus infections leading to polyomavirus associated nephropathy (PVAN/BK virus nephropathy) or JC virus associated progressive multifocal leukoencephalopathy (PML), with serious and/or fatal outcomes reported (§4.4, §4.8)
- Malignancy — increased risk of lymphomas, lymphoproliferative disorders and other malignancies, 'particularly of the skin'; 'The frequency of malignancies increases with the intensity and duration of therapy' (§4.4, §4.8)
- This side-effect list may be incomplete — check the full SPC.
Monitoring
- Renal function — establish a reliable baseline from at least two measurements before starting, then assess frequently; apply the eGFR-based dose-reduction rule in renalAdjustment (§4.2, §4.4)
- Blood pressure — §4.2: 'Regular monitoring of blood pressure is required'
- Liver — §4.2: 'The determination of bilirubin and parameters that assess hepatic function are required prior to starting therapy and close monitoring during treatment is recommended'
- Biochemistry — §4.2: 'Determinations of serum lipids, potassium, magnesium and uric acid are advisable before treatment and periodically during treatment'
- Ciclosporin blood levels — §4.2: 'Occasional monitoring of ciclosporin blood levels may be relevant in non-transplant indications, e.g. when Capimune is co-administered with substances that may interfere with the pharmacokinetics of ciclosporin, or in the event of unusual clinical response'; blood-level monitoring is required for transplantation patients when switching oral formulations
- Skin surveillance and sun protection — §4.4: patients, 'in particular those treated for psoriasis or atopic dermatitis, should be warned to avoid excess unprotected sun exposure and should not receive concomitant ultraviolet B irradiation or PUVA photochemotherapy'
- Infection surveillance — consider polyomavirus-associated nephropathy or PML in immunosuppressed patients with deteriorating renal function or neurological symptoms (§4.4)
- Prescriber setting — §4.4: ciclosporin should be prescribed only by physicians who can provide adequate follow-up 'including regular full physical examination, measurement of blood pressure, and control of laboratory safety parameters'
Clinical monograph
How it works
It binds cyclophilin and inhibits calcineurin, blocking the transcription of interleukin-2 and other cytokines and thereby suppressing T-lymphocyte activation.
Prescribing in practice
- Nephrotoxic and hypertensive — renal function and blood pressure must be measured before and regularly during treatment, with dose reduction or withdrawal if creatinine rises persistently.
- Numerous interactions occur via CYP3A4 and P-glycoprotein; avoid concurrent live vaccines and minimise other nephrotoxins.
- Prescribe and dispense by brand name because formulations are not interchangeable, and check the SPC for the relevant indication.
Monitoring
Monitor serum creatinine, blood pressure, potassium, liver function, lipids and (where indicated) blood ciclosporin concentrations during therapy.
Counselling the patient
- Report swelling, reduced urine output or persistent headache.
- Avoid grapefruit juice and tell clinicians about all other medicines.
- Use sun protection and attend monitoring appointments.
Evidence & guidelines
Long-standing use is supported by controlled trials and UK guidance for severe refractory inflammatory arthritis.
